المستخلص: The study had included isolation and diagnosis of three hundred samples for both sexes their ages were between (1 - 60) years of the inpatients and outpatients in Tikrit Teaching Hospital and General Samarraa Hospital during the period from 1/9 / 2011 to 1/3/2012. The infections were distributed among the burns infections, the wounds, urinary tract infections (UTI) and female genital tract infections (High vagina). This study clarified that (192) sample from the total samples showed bacterial growth in percentage 64%. The results of this study indicated to the proportion 58% with (UTI) by (87) bacterial isolation were produced from (150) isolation. The percentage of burns infections were 81.81% from (55) sample which distributed among the first, second and third class burns. The burns of second and third class gave bacterial growth in a proportion 100% while the first class burns gave 64.28%. Concerning the wounds infections, bacterial growth was 62.9% from (62) sample. The infections proportion of (H.V) was 63.63% from (33) sample. The results of the current study showed that the infections in females were higher that in males with respect to (UTI), while there was not considered difference between the males and females about the burns and wounds infections. Differently, the (H.V) infections were just for the females in the ages between (18 - 45). It was clear according to the results of diagnosis that Escherichia coli had the highest proportion of isolations 25.52% from the total isolates followed by Staphylococcus aureus 18.23% Pseudomonas aeruginosa 15.63%, both Klebsiella pneumoniae and Proteus miribilis 10.42% Staphylococcus epidermidis 4.69% Citrobacter freundii 4.17%, Staphylococcus saprophyticus 3.64% both Serratia marcescens and Enterococcus faecalis 2.6%, Streptococcus pyogenes 1.56% and Staphylococcus intermedius had the least percentage 0.5% by one from (192) isolate. The sensitivity of these isolates was tested by (10) antibiotic which included quinolones, aminoglycosides, beta - lactams and tetracyclines antibiotics. Among these antibiotics imipenem and ciprofloxacin were more effective, while the other antibiotics were different either active or not active at all.The wheat germinating was used in this study with the ages (36 - 48) hour and its activity was tested by using some bacterial kinds. After completing several quantitative and qualitative tests on this germinating, the carbohydrates proportion was between 67 - 70%, the protein proportion by folin method was between 10 - 8%, the lipids proportion was 1.5%.Some mineral elements in germinated wheat were estimated which include Calcium, Iron, Magnesium, Potassium, Copper, Manganese, Zinc, Selenium, and Sodium element, active materials were also estimated in the wheat germinating extracts which had inhibitory effect on the microbiology. It was clear by the tests that the germinating contains a lot of Phenolic compounds, Terpeniods, glycosides and steroids. These materials were extracted by using some extracts included the cold water extracts and hot water extracts, alcoholic extracts (ethanol and methanol) and phenolic extract. All the extracts prepared in concentrations (25, 50, 100, 200) mg/ ml. This study showed that the phenolic extract had high effect on the bacterial kinds in comparison with the methanolic and ethanolic extracts at (200) mg/ ml concentration while the cold water extract had less effect on these bacterial isolates in comparison with the above extracts, finally the hot water extract had no inhibitory effect against any isolated bacterial type with all the concentrations. The inhibitory action of these extracts was compared with some antibiotics as a control sample. These antibiotics represents different groups of antibiotics and which contained Imipenem, Ciprofloxacin, Gentamicin, Ceftazidime in addition to Augmentin.In this study the minimum inhibitory concentration (MIC) of the fenolic, alcoholic and watery extracts was determined and the concentration was different according to the extract type, the bacterial type and the isolation site.

The most common fungi isolated from patient were Aspergillus Spp.36). (%22 followed by Candida Spp. (%67. 10), Trichophyton Spp(%6.5) , and Penicillium spp. (%3.94%), Aspergills niger appeared as the predominant fungi (%84. 36) followed by Aspergillus flavus (%36. 22), Candida albicans (42. 18%), Aspergills terrous (7.89%) , Candida kruzi, Penicillium spp (3.94%), Trichophyton mentagrophyte, Trichophyton verrucosum (63. 2%) and Trichophyton scheonlieni (%1.31), and no fungi were isolate from the healthy person. Higher percentage of fungi infection were recorded in female 46(60.52%) than male 30(39.47%). and the higher percentage for fungal infection was recorded in the age group (31 - 40) with percentage (23.68%). fungal ear infection was recorded with highest percentage in right ear 47 (61.84%), and for the left ear 29 (38.15%). and high rate of infection was recorded in august (73.69%), Higher percentage of infection was recorded in patient house wives (52.36%), the itching was the most commen symptom , The most habits used to clean the ear by dearty body (51.31%), Ahigher percentage (76.4%) recorded in non educated persons. The results of active ingredients test for Syzigium aromaticum and Ricinus communis revealed that clove dry flower buds contain Flavonoides, Glycosides, Tannins, Volatile oils, Terpenes, Resins, and Phenols, while castor leaves contain Flavonoids, Tannins, Volatile oils, Terpenes, Resins, Saponins and Phenols, pH of clove bud 4.3 and pH of castor leaves 5.8. Aqueous and alcoholic extracts were Prepeared, which belongs to Syzigium aromaticum and Ricinus communis under the study, commercial oil for clove and seed castor were used in the study, the effects of inhibition of Aqueous and Alcoholic extracts and commercial oil had been studied on the growth and protease production on the three fungi which were showed the high ratio appeared among the isolation sample under the study with 5 concentration 10, 20, 30, 40, 50 (mg /ml), and the affected rate of these extracts and oils under the study on fungi were varied. The relation between Aqueous extract of clove bud and fungi growing was increasing relation, While Alcoholic Extract and commercial oil showed preference in the inhibition of the isolated fungi grown while its effect on Candida albicans was increase with increase the concentration, The effect of aqueous and Alcoholic Extract of castor leaves on Moulds showed reverse effect. on the other hand the commercial oil effect was slight effect, and both extracts did not showed effect on the Candida albicans as well as the Commercial oil.When adding Clove Extracts and Commercial oil and in all concentrations dose not gave any production of the Protease enzyme in the solid media, whereas the extracts of castor leaves and commercial oil were showed effects on the production of Protease enzyme, and Aspergills niger was more effected and these extracts did not showed an effect on the Candida albicans.Aqueous and Alcoholic extract and commercial oil to the Clove revealed higher influence rate than the effect of the Castor leaves extract , and in a different rate

The samples included of patients in Medical City Hospital and Al - kindy Hospital (15 urine, 60 blood, 50 root canal and 10 wound swabs) Antibiotics susceptibility test for 20 isolates was done against 11 antibiotics, it was revealed that the isolates showed multi drug resistance were (18) isolates. The vancomycin susceptibility was determined by the minimum inhibitory concentration (MIC). Resistant and intermediate resistant to vancomycin was distributed among isolates at a ratio of 65% and 20%, respectively. Imipenem was found to be the most bactericidal agent against E. faecalis isolates E. faecalis virulence factors were detected phenotypically, The results showed that all isolates (100%) were hemolysin, protease and aggregation substance producer. 30% of isolates showed an ability to produce gelatinase. While (40.7%) of the isolates were a lipase producer. The results of the tube method showed that all E. faecalis isolates (100%) were slime layer and biofilm producer but the amount of adherent layer were different among the isolates ranged from strong to moderate and weak.The extracted DNA was subjected to Polymerase chain reaction (PCR) technique in a monoplex pattern to amplify the virulence factor Enterococcal Surface Protein (esp) which is chromosomal, results of this investigation showed that 20 (100%) E. faecalis isolates gave the amplicon size 933 base pair for the esp gene.The genetic determinants of Vancomycin - Resistant vanA and vanB genes were amplified using monoplex and multiplex PCR techniques in order to identify vancomycin resistant (van+) and sensitive (lacking van) among (13) E. faecalis. The vanA, vanB genes were detected in 11 and 4 E. faecalis isolates, respectively. The results of monoplex and multiplex PCR revealed that the molecular weight of vanA and vanB genes were 550 and nearly 600 bp, respectively. The results revealed that the vanA and vanB amplicons have a genetic variation in their molecular weight during the electrophoresis of PCR product.

المستخلص: The aim of This study is to determine the prevalence of OXA ? - lactamase in pseudomonas aeruginosa isolates from clinical and other environmental cases in Al - Diwaniya Teaching Hospital using phenotypic and molecular methods.The Samples of the study were collected from various sources and they were 390 samples for the period from November 2011 to March 2012, and they includ (292 clinical specimens and 98 environmental sample), the results of cultural and biochemical tests showed that 50 isolates (39 of them were from clinical cases and 11 were from environmental samples), belonged to ps. aeruginosa, and their diagnosis were confirmed by 16s - ribosomal RNA, and the study showed that all the isolates containing the 16s - ribosomal RNA gene, which represents the designed diagnostic gene in this study.The results of this study showed that the higher rate of P. aeruginosa isolates was due to burns infections (23.68 %) , followed by respiratory tract infections (sputum) that were (15.38 %) and then the case to otitis media infections (12.5 %), and lastly that due to urinary tract infections (10.49 %), while the rate isolation from the environmental samples was (5.11 %) from the floor of burns department, followed by (10.8 %) from the medical instruments of department workers.It was noted from this study that the age and gender of the patients have some effect on the infection by P. aeruginosa it was recorded that the higher rate of infection was in patients older then 61 year old, and regarding gender, it was found that females are more infected than male, especially in urinary tract infections. The study showed that there is high rate of infection in the admitted patients, in older people and in those who need urinary catheterization, in addition to those with severe burns and those in the intensive care units. Drug sensitivity test had been carried out for all the bacterial isolates to 22 types of antibiotics by disk diffusion method of Kirby - Bauer, and this study had indicated that there was relatively high resistance from P. aeruginosa to ? - lactam antibiotics, aminoglycoseides, and fluoroquinolone. The results also showed that the studied isolates has possibility of producing broad - spectrum ? - lactames enzymes, and this is supported by the resistance of this bacteria to the third generation cephalosporins and to Alaztronam, it was also shown that there was difference in the resistance to carbapenems antibiotics, the resistance rate to imipenem and meropenem were 16% and 64 %, respectively. Polymyxin B and Polymyxin E also called (Colistin) antibiotics were also used, and the resistance rate %0 for Colistin and %4 for Polymyxin B, that means there was two isolates which are resistant to Polymyxin B and this resistance was a challenge to the success of therapeutic efforts. this study noted that there was 22 (44%) isolates which were resistant to at least three types of antibiotics, and regarded as multi - drug resistant (MDR) and Extensive - drug resistance (XDR) isolates were26 (52%) which was the higher rate among the three types of resistance, The third type of resistance was 2 (4%) which represents the resistance to all types of studied antibiotics (PDR). The ability of these isolates to produce broad - spectrum OXA ? - lactames enzymes groups was investigated thrrough detection of presence of genes blaOXA - 10, blaLCR - 1, blaOXA - 18, blaOXA - 1, blaOXA - 2 in these isolates by using the polymerization chain reaction enzyme technology] (PCR) it showed 50/50 (100%) isolates contain blaOXA - 10 gene, which belongs to the OXA group I, and the results of this study showed no amplification results for blaOXA - 18, blaLCR - 1, blaOXA - 1, blaOXA - 2 genes, which belong to the main groups of broadspectrum OXA ? - lactames enzymes which are OXAgroup II, OXAgroup III and OXA groupV respectively except OXA18 enzyme

The results of the present study showed that 56% of the subjects were pregnant and 44%were not. The highest percentage of the infected subjects was of 26 - 30 years old as 30.37% among the pregnant women and 36.35% among the non - pregnant women of the age mentioned above. The highest percentage 37.5% of abortion of the first period of pregnancy was in pregnant women, and 45.53% in non - pregnant women. The results of the study also showed more cases of infected women among those who bred animals in their living places as 69%. It is also found that the highest percentage of the infected women 64% were of those who use the running water for drinking. Moreover, it is noticed that there is an increase in the percentage of the infected women among the uneducated women 38%. The study showed that the percentage of the infection is proportional to residence 63%, the infection increase among women living in rural areas. The percentage of T - lymphocytes in peripheral blood of patients were also measured through measuring the percentage of the CD4+ and CD8+cells by using fluorescent microscope.The results showed a significant decrease (p<0.05) in this type of cells.The rate of percentage of CD4+ of the patient's were 31.704±0.116 while the rate of CD4+ in the peripheral blood of the control group was 62.260±0.237.The rate of percentages of CD8+ 19.382±0.080, whereas it was 31.680±0.307 of the control group.The rates of the percentages of CD4+ to CD8+ were also measured, the results showed a significant decrease (p<0.05) in the rate of the percentage in the patient's group 1.642 while it was 1.968 in the control group. The statistic analysis showed significant differences between these tow groups (p<0.05). The intensity of Zinc and Copper has been measured in the serum of the infected women via use of Atomic absorption instrument, a significant decrease (p <0.05) appeared in the rate of Zinc intensity in the serum on the infected women as compared with the control group.The rate of the intensity in patient's group was 4.65% ± 2.628µmol /l while in the control group it was 15.353± 1.640 µmol /l.A significant increase (p<0.05)was also noticed in the intensity of Copper in the patient's group (28.589±4.335 µmol /l)whereas it was 12.854±1.501 µmol /l in the control group. The index of the specific antibodies IgM and IgG related to Toxoplasma gondii was measured by ELISA method, a significant increase (p<0.05) was observed in the value of IgM and IgG in the patient's group as compared with the control group. The rate of index for IgM in the patient's group was 1.354±0.05 while it was 0.163±0.05 in the control group. The rate of value of IgG in the patient's group was 1.163±0.074 whereas it was 0.358±0.033 in the control group. In the present study, Toxoplasma gondii was isolated and diagnosed from human as first attempt, and then the infection was created in laboratory mice as an essential step for growing the parasite. The second step was studying the effect of some selected drugs on the experimental treatment for disease of toxoplasmosis created in the mice. The drugs are : Pyrimethamin, Clarithromycin, Spiramycin, Ivermectin.The results of the study showed the effects of these drugs on the tissue cyst formed in the brain and lungs. The number of tissue cysts in the brain of the mouse treated with pyrimethamin was 14.8 ±1.067 after 28 days. Significant differences appeared when this result compared with the control group in which it was 27.4±1.029. The number of tissue cysts formed in lung, tissue in the mouse treated with the same drug after the same period of the time was 6.2±0.583.This showed a significant differences as compared with the control group in which it was 10.2±0.583. No significant differences appeared between both groups as for the treatment by Clarithromycin antibiotic as far as the number of the tissue cysts formed in the brain after 28 days is concerned. The number was 23.8 ±0.86 as compared with the control group 38.6±1.029.The same compared is true of the lungs, tissue. The number of the tissue cysts was 23.8±0.86 as compared with the control group 28.4±1.805. Concerning the antibiotic Spiramycin, the results showed the effectiveness of it in decreasing the tissue cysts formed in the brain.The significant differences were (p<0.05), the rate of the cysts was 9.6±0.6 as compared with the control group in which it was 22.8±1.067.The same effectiveness appeared on the lungs, tissue as the rate of tissue cysts after 28 days of treatment was 4.6±0.509 as compared with the control group in which was 17±1.14 and the significant differences were (p=0.000).The Ivermectin drug showed a great effectiveness in minimizing the number of the tissue cysts formed in the brain and the lungs. The numbers of the tissue cysts formed after 28 days were 3.2±0.374 and 1±0.316 respectively; significant differences are observed when these numbers are compared with the numbers of the control group which were 22±1.843 and 19.4±1.435. Thus, the use of Ivermectin drug is considered as a pioneer and fruitful study since this drug has not been used for the treatment of Toxoplasmosis.

المستخلص: هدف البحث الى التعرف على فاعلية التدريس باستراتيجية التعلم بالتعاقد في تحصيل مادة علم الاحياء لدى طلاب الصف الثاني المتوسط وتفكيرهم الابداعي. وللتحقق من ذلك تم صياغة الفرضيتين الصفريتين الاتيتين : 1 - لا يوجد فرق ذو دلالة احصائية عند مستوى (05.0) بين مت | 50 isolates of the bacteria Pseudomonas aeruginosa was obtained from 201 clinical samples were distributed between Burn Specialist Hospital and teaching laboratories from patients with burns, infected wounds, middle ear infection, urinary tract infection and respiratory tract infection for a period from 1st February till 1st May. And we obtained 50 bacterial isolates from 20 samples from contaminated and non - contaminated soils were distributed different areas of Baghdad for a period of 1st May 2013 till 1st August.Number of cultural microscopically, biochemical and sensitivity to antibiotics tests had been, than diagnosis was confirmed by API20E system.These isolates was tested for ability to production of biosurfactants (rhamnolipid) by haemolysis, oil spreasding test, calculate value of emulisification factor (E24) and measuring surface tension for liquid media. Tow isolates (PS42 and PP8) had been selected, first one was from soil samples and other was from pathological samples because of they have highest productivity, haemolysis ability, oil spreading, highest emulisification factor value and highest in lowering surface tension, there for these tow isolates selected for study their inhibitory activity against types of bacteria. The rhamnolipid was extracted from tow isolates P. aeruginosa PP8 and P. aeruginosa PS42 by using mixture of solvents as was obtained 15.45 g and 18.25 g per liter of each of the PP8 and PS42 respectively. The rhamnolipid was diagnosed by thin layer chromatography technology (TLC) and high - performance liquid chromatography (HPLC) showed that tow bacteria produced three types of rhamnolipids (mono - , di - rhamnolipid and rhamnolipid A). The rhamonlipid efficiency was tested for inhibitory activity against bacteria by measuring diameter of inhibitory zone surrounding holes and discs. The inhibitory activity was high against Bacillus cersus bacteria followed by P. aeruginosa, than Staphylococcus aeraus and the lowest one was E. colli. The inhibitory activity for biosurfactant was approached to inhibitory activity for industrial surfactants. Also in this study has been determined minimum inhibitory concentration (MIC) value and Minimum Bactericidal Concentration (MBC) value for biosurfactants and the results varied depending on different types of biosurfactants and type of bacteria and the lowest values for MIC and MBC of biosurfactant produced by P. aeruginosa PS42 on growth of B. cereus and reached to 16.It was first time at local level for testing inhibitory activity of biosurfactant against pathogenic bacteria S. aureus and P. aeruginosa which was studied in vivo (injuried skin) after introduction these pathogens experimentally into laboratory mice with clinical symptoms appeared in injured skin after 48 hours and then treated mice groups with of 30 mg \ ml concentration of biosurfactants produced from isolates of bacterial (P. aeruginosa PP8 and P. aeruginosa PS42), resulted in a decrease in the time required for healing as found from the results obtained by the different length of period needed for healing (depending on the nature of injury and type of microorganism that causes injury).The mice had been recovered after 5 days when used biosurfactant at concentration 30 mg/ml produced P. aeruginosa PS42 followed by mice recovered after 6 days when used biosurfactants 30 mg/ml produced by P. aeruginosa PP8 in comparison with control group which recovered after 12 days for mice infected with S. aureus. In mice infected with P. aeruginosa recovered after 10 days when used biosurfactant produced by P. aeruginosa PS42 at concentration 30mg/ml and followed by mice recovered after 12 days when used biosurfactant produced by P. aeruginosa PP8 at concentration 30mg/ml in comparison with control group which recovered after 17 days.

The direct examination shows positive results of 72 samples which represent 72% while for laboratory growth results, its shows 65 samples with positive results 65%. There are three types of Trichophyton fungus had been isolated which are T.rubrum 28 isolates, T.mentagrophytes 16 isolates and T.schoenleinii 4 isolates and there was one type of genus Microsporum which is M.canis 24 isolates. The results show that Tinea corporis infection is the common and its more among females than males where it is 26.39% and 13.89% respectively, then Tinea capitis which is 19.4% in males which is higher than in females which represents 13.89% while Tinea unguium was in females more than males which was in females 16.67% while in males 9.72%. The percentage of fungal skin infection was differ according to the location where the number of infections in the rural area for all types of Tinea were more than the number of infection in the urban area where the number of infected people with Tinea corporis was 18 which represent 25% while in the urban the number was 11 which represent 18.28% while the number of infected people with Tinea capitis in the rural area were 16 which represent 22.22% and the infected in the urban were 8 which represent 11.11%. While Tinea unguium the number of infected people in the rural 10 which represent 13.89% and in the urban 9 people which represent 12.5%. The diagnosis of isolated fungi depended on phenotype of fungal growth and microscopic examination, in addition to special tests for diagnosing skin fungal infections. Also the PCR was used for diagnosis and the work had been completed by using genotypic tree for fine diagnosis and detection the fungal species. The result were send to the genes bank site to be sure about the fungus type through comparison with the registered fungi in this site and by using MEGA6 program for genetic tree analysis of type (unweighted pair group method with arithmetic mean). The results of analysis shows clear converge of local Trichophyton spp. Isolates with Trichophyton rubrum in comparison with other types that appears in the genetic tree analysis while Microsporium diagnosed through genetic tree analysis of type (up GMA tree) and the result of analysis shows clear converge of local Microsporium spp. Isolates with Microsporium canis compared with other types of genetic tree analysis. The effect of silver nanoparticles that is used against growth of T.rubrum, T.mentagrophytes and M.canis. The results show that all the concentrations used were effective in stopping of growth of T.mentagrophytes when deal with the standard measure when dealt with concentration of 4 mg/l the more effective in stopping of radiating growth of the fungus. Regarding the fungus T.rubrum the concentrations of 4 mg/l more effective in stopping of growth while there was no difference for 1mg/liter concentration. Regarding the fungus M.canis, the mentioned concentrations had large effect on fungal colonization growth compared with the standard and this fungus more than other fungi affected by nano silver ions

Stool samples were examined by direct method using brine (Normal Saline) and tincture of iodine (Lugol's Iodine) and the floating way by sulphate zinc water (ZnSo4.7H2O) to investigate the prevalence of intestinal parasites and the relationship of infection by age, sex, number of family members, and the type of water used for drinking. The results showed the presence of significant difference at the possibility(p<0.05) in total infection for the regions of Abu Ghraib and Ameriyah where the percentage was (36.29%) in the area of Abu Ghraib and (27.57%) for the Amiriyah area. It has been diagnosed five types of intestinal parasites (protozoa + Helminthes) as follows : A - Intestinal protozoa in the Abu Ghraib and for the Amiriyah area : 1 - Entamoeba histolytica was (17.62%, 16.68%).2 - Giardia lamblia was (11.95%, 5.49%).3 - Entamoeba coli colon was (2.44%, 2.55%(.B - Helminthes1 - Dwarf tapeworm Hymenolepis nana was (2.37%, 1.76.(2 - pinworm Enterobius vermicularis was (1.88%, 1.07.(We Did not observe any significant differences between the infection of intestinal parasites and sex factor where the total infection for males was (6.53%) while for females, it reached (8.06%) for Abu Ghraib, as to the Amiriya region, also we did not notice any significant differences between the infection of intestinal parasites and sex factor where The total infection for males was (7.26%) while for females, it was (6.84%(. It has been also found that there are significant differences and when probability of (P <0.05) for the infection with parasite (Giardia lamblia) between the areas of Abu Ghraib and Amiriyah where infection rate reached (11.9%) in Abu Ghraib while for the Amiriyah area, it has reached the ratio of, (5.49%) for the same parasite, while there was no significant difference between the other four types of parasites. The individual injuries are prevalent Lama has reached bilateral injuries (56) bilateral injury in the Abu Ghraib area, and (13) in the area of bilateral injury Ameria and most of the injuries were bilateral parasite (E.histolytica+ G.lamblia). The results showed that there is a significant difference when probability (P <0.01) for the distribution of age groups, reaching the highest infection rate in the age group of (29 - 20) years, (56.68%) and the lowest infection in the age group (60 years and over) the percentage of infection was (21.42%) in the Abu Ghraib area, while for Amiriyah area, it has been recorded the highest infection rate in the age group of (29.20), where it reached (49.22%) and the lowest injury in the age group (60 years and above) where The percentage of infection was (4.82%(. Also, it was noticed the emergence of variation in the values of the components of the peripheral blood and the lack of significant difference when probability (P <0.05) in the area of Abu Ghraib where it recorded the highest proportion of hemoglobin in the parasite (Entamoeba histolytica), amounting to (12.40 g / 100 ml) and the lowest percentage hemoglobin was recorded in parasite (Enterobius vermicularis) amounting to (9.46 cells / mm3), and the lack of a significant difference in the total number of white blood cells where it recorded the highest rate in the parasite (Entamoeba histolytica) 6776.32 cells / mm3 while the lowest rate was recorded in the parasite (Enterobius vermicularis (5074.37cell\mm3, and lack of a significant difference for eosinophile numbers was recorded the highest proportion in parasite Hymenolepis nana 516.63 cell\mm3 and the lowst rate was recorded in parasite Entamoeba histolytica 159.63 cell\mm3. As for the Amiriyah, it hasn’t been noticed any significant differences when probability (P <0.05), where the highest proportion of hemoglobin in the parasite (Entamoeba histolytica), was (11.76 g / 100 ml) and the lowest percentage hemoglobin recorded in parasite (Enterobius vermicularis) was (9.90 g / 100ml), and there was the lack of a significant difference in the total number of white blood cells, where it has been recorded the highest rate in the parasite (Entamoeba histolytica) 6574.59 cells / mm3 and the lowest rate was recorded in the parasite (Entamoeba coli) 5700.00 cells / mm3 and the lack of a significant difference for eosinophile numbers. The highest proportion in parasite Enterobius vermicularis was 518.65 cell\mm3 and the lowst rate in parasite Entamoeba coli was 140.29 cell\mm3. The results also showed that there is a high significant difference when the probability (P <0.01) in the incidence of intestinal parasites and the relationship of water used for drinking where the study proved that the highest infection rates recorded of the people who use canal waters and water tank where It percentages was (49.54%, 39.00%), respectively while the lowest rate of infection was recorded in people who use boiling water which reached (14.02%).

المستخلص: اجريت هذه الدراسة للمدة من كانون الثاني 2011 ولغاية كانون الاول 2011 للمرضى الراقدين والمراجعين لمستشفى تكريت التعليمي وبعض المختبرات الخاصة في مركز المدينة وضواحيها والذين يعانون اعراض مرضية مختلفه ولفئات عمرية مختلفة ترواحت بين اقل من سنة الى 61 سنة، ح | This study was conducted for the period started from January 2011 until December 2011 on inpatients and outpatients of Tikrit educational hospital and some private laboratories at Tikrit city and surrounded suburbs. Symptoms of different diseases among various age groups varies between less than one year to 61 years. The tests used the (ELISA & PCR) and the analysis of the PCR - RFLP to discriminate the infection by assemblage of Giardia lamblia and differentiate between pathogenic amoeba Entamoeba histolytica and nonpathogenic Entamoeba dispar compared with microscopical examination. The result of present study showed that (75) person who represent (37.5%) were infected by Giardia lamblia and (75) person who represent (37.5%) were infected by E.histolytica/E.dispare complex, out of (200) stool samples which have been tested by microscopical examination. Epidemiological study showed no significant difference among the sex for the two species parasites whereas a high percentage for infection recorded in group at age (1? - 10) year for Giardia lamblia and E.histolytica / E.dispar complex reach to (60%, 36%) respectively. Regarding the place of living Giardia lamblia in rural area showed infection rate of (19.5 %), while infection rate by E.histolytica/E.dispar complex reaches (22.5%) in urban area. Statistical analysis shows a high difference of significance according the source of water supply. Tap water showed high incidence for initiating infection which reaches to (93.3%) by G.lamblia and (90%) for E.histolytica/E.dispar complex. For the infection rates and their relationship to the educational level, the results show that the highest rates of infection recorded in non - educated (52%) and (73.3%) of Giardia lamblia and E.histolytica / E.dispar complex, respectively. Depending on the sample texture, the result show that oily diarrhea is more correlate with infection reaches to (33.3%) of Giardia lamblia and the watery diarrhea form 40% by E.histolytica / E.dispar complex, while simultaneous occurrence of both symptom (colic and loss of appetite) are the most symptom synchronized with infection records (44%) for Giardia lamblia and (36%) for E.histolytica / E.dispar complex. The percentage of infection by Giardia Lamblia in this study depends on the test results of the ELISA was (20%), while the percentage of infection E.histolytica/E.dispar complex was (6.7%). Testing has shown sensitivity compared to microscopic examination reaches to (22.6%) and (8%) for both parasite respectively, while the test showed a high specificity which reaches the rate (93.3%) and (100%) for both parasites respectively. Result of PCR showed a percentage of infection by E.dispar about (32%) (64 sample) from the total samples, whereas it does register any cases infection by E.histolytica. By counting the results of the PCR for the three genes (ssu rRNA + TPIA + GDH) they show a total infection by Giardia lamblia which was (10.5%) (21 samples). This study recorded percentage of infection Giardia lamblia depending on the result of the three Genes separately amounted to (4%), (5%), (3%) for (ssu rRNA, TPIA, GDH) respectively. According to the result of the analysis PCR - RFLP for GDH gene by using the enzyme NIaIV, it did not record any infection by Giardia lamblia (assemblage A), whereas (6 samples) recorded (100) by Giardia lamblia (assemblage B), by using the enzyme Rsal to determine the secondary assemblage shows that the total (6 samples) infected there are 5 samples carrying infection by two type of secondary assemblage returning to the assemblage B (assemblage BIII +BIV) and only one sample infected with (assemblage BIV). To determine the assemblage and secondary assemblage for the parasite result compared with amplification of TPIA gene with lysis by enzyme for the resulting amplification for GDH gene, resulting a ratio of (14.3%) for a sample infection by both assemblage (A+B) and secondary assemblage (BIII+BIV) together, and a ratio of (57.14%) infection by assemblage A only and (21.4%) infection by secondary assemblage (BIII+BIV) together and (7.14%) infection by BIV only.

Six LAB isolates and the identification was depended on the morphological and cultural characterized and biochemical testes, the isolates were determined as Lactobacillus delubricii subsp. delubricii, Lactobacillus delubricii subsp. bulgaricus, Lactobcillus casei, Lactobacillus acidophilus, Leuconostoc mesentroides and Streptococcus thermophilus, and four fungal species Microsporum canis, Trichophyton mentagrophytes, Aspergillus fumigatus and Rhizopus stolinfer were identified. In this study the highest inhibition effect against the above mentioned fungi was shown by L. acidophilus as a significant (P< 0.05) efficacy where the diameter of inhibition zone in case of M. canis, T. mentagrophytes, A. fumigtus and R. stolonifer was 26, 32, 30 and 28 mm respectively. Less inhibition activity was exhibited by Leu. mesentroides and Str. thermophilus while the lowest inhibition was shown by L. delubricii. Results showed also that the temperature optimal for the growth of bacterial species (except L. casei and Str. thermophilus) tested and their inhibition activity was 30 °C. However, temperature of 35 °C was the optimal for the highest inhibitory effect of both L. casei and Str. thermophilus. At 25 °C of studied bacterial species showed decreased inhibitory effect against the tested fungi. Concerning the pH, the present study showed that the highest inhibitory of all tested bacteria species (except L. acidophilus) was at pH 6.5, L. acidophilus showed such activity at pH 5.5. This study revealed that the inhibitory effect of metabolites produced mixture of the tested bacterial species was directly proportional with its concentrate. Where this mixture was used at media concentration of 10, 20 and 40 mg/ml cultural. However, metabolic products from L. acidophilus, Leu. mesentroides and Str. thermophilus was the most effective in inhibition activity compared with the rest of the bacteria species used particularly at 40 mg/ml cultural media

Atotal of 155 sample from different clinical source has been collected during the period from October - 2012 to March - 2013, these include 20 samples from vaginal smear, 8 samples from saliva and 6 samples from human milk.The results of primary isolation, Laboratory diagnosis and biochemical test showed that 34 isolates has bee identified as L.salivarius.Ahigh precent of isolation has been carried out from human milk which was 40%. The ability of all isolates to produce gelatinase and biofilm has been detected and the results revealed the ability of some isolates to produce gelatinase and biofilm. Ahigh percent of gelatinase production has been detected in L.salivarius isolated from milk sample (50%), while alow percent of gelatinase production was 0% in L.salivarius isolated from saliva. The results of optical density of biofilm produced by L.salivarius isolates from milk which was 100% higher than it in isolates from vaginal and saliva which was 85% and 75% respectively. All isolates shows antibacterial effect against some Gram negative bacteria, the diameter of inhibition as between (2 - 8), the results showed the ability of 4 selective isolates of L.salivarius to produce bacteriocin in which the Rf valve of precipitate bacteriocin was (0.42 - 0.6) compard with leaky bacteriocin hich was (0.57 - 0.8), also leaky bacteriocin as more activity against G - ve bacteria than precipitate bacteriocin. The result of plasmid profile in L.salivarius revealed the presence of megaplasmid in all isolate except one which had one megaplasmid and one small plasmid. Bacterial conjugation between L.salivarius that produce bacteriocin and had megaplasmid which used as adonor cell with E. coli Jm 109 as a recipient cell showed transferring of megaplasmid from donor to recipient cell and the transconjugant cells showed high anti - bacterial effect due to bacteriocin production against G - ve bacteria. The result of amplification of Sal P gene encoding salivracin P by PCR confirmed that all isolate had no Sal P gene in there genetic materials which revealed that these isolates had another type of bacteriocin rather than Salivracin P.

المستخلص: Six Bifidobacterum isolates were isolated from fully breast - fed healthy infant faeces on reduced de Man Rogosa and sharp medium (MRS - C). Isolates identified on the basis of, colonial and microscopical properties, biochemical tests, and fructose - 6 - phosphate phosphoketolase enzyme (F6PPK) activity assay in cellular extracts. Carbohydrates fermentation profile used for identification of isolates to species level. All bacterial isolates diagnosed as Bifidobacterium genus where in this study B. adolescntis was the predominant species (50%), (B4, B5 and B6), followed by B. breve (B3), B. longum (B1) and B. dentium (B2) each one represent 16.67%.Bifidobacterium isolates were screened for their antagonistic effects against test organism, clinical isolate of shiga toxin producing E.coli O157 : H7 (STEC), using agar - well diffusion method. The isolates B3 and B6 showed clear inhibitory actions, 22 mm and 15 mm diameter of inhibitions zones, respectively. The rest of the tested isolates did not pronounce any inhibitory activity.B. breve in vivo antagonistic behavior and the possible protective effects against STEC was evaluated, using streptomycin treated murine model. Murine intestines was stably colonized orally with B. breve for 14 days, in conjunction mice were challenged orally with STEC, 103 CFU / mouse / day on day 8 of experiment. Bacterteriological analysis of mice faeces at time intervals, was indicated high levels of bacterial colonization were achieved in intestine by B. breve and STEC.Colonization of mice intestine by B. Breve did not inhibited STEC cells from proliferation during infection phase. Hence, the excretion level of STEC in faeces reached to 2.4 x 10 6 CFU/ g of faeces.STEC infected mice showed no severe clinical signs, characterized by hairloss, lethargy, paralysis of fore limbs, and shed of loose faeces. In the B. breve - colonized group, the mentioned clinical signs were almost completely inhibited, except the lethargic of some animals.Immunological studies showed an increase in the levels of sIgA by 2.7 - fold from that of blood IgA in B. breve - colonized mice while, reversed values were recorded in mice infected with STEC, blood IgA level was 1.95 - fold higher than that of sIgA.Histological changes in spleen, liver, kidney, and intestine tissues of mice were studied. The histological sections clarified the protective roles of B.breve, where no effective histological disorders were appeared in B.breve and STEC - colonized mice. In the STEC - infected mice, the pathological abnormalities within the kidney was the predominant, diagnozed as ulcers in the lining membranes, glomerular and tubular epithelium necrosis, without evidence of glomerular thrombi, mild damages was appeared in liver and spleen, and characteristic attaching and effacing (A / E) lesions appeared in the large intestine sections

المستخلص: للفترة من اذار 2014 الى اذار 2015 تم جمع 1300 عينة سريرية مختلفة (عينات ادرار ومسحات جروح وحروق وعينات دم ومسحات من الفم والاذن والعيون بالاضافة لعينات البراز والقشع) من اثنين من مستشفيات محافظة بابل (مستشفى الحلة التعليمي ومستشفى بابل التعليمي للنسائية و| During the period between March 2014 and March 2015, a total of 1300 clinical specimens (urine, wounds, burns, blood, throat, ear, eye, stool, and sputum) were collected from two hospitals in Babylon province; Al - Hillah Teaching Hospital, and Babylon Hospital for Maternity and Pediatric. All specimens were cultured and 10 Acinetobacter baumannii isolates were obtained from clinical specimens in a percentage of (0.76%) distributed in blood 1 (0.6%), urine 2 (1%), wound infection 1 (0.75%), burn 5 (0.85%) and throat 1 (2%). This study was conducted to determine the occurrence of carbapenem resistant A. baumannii isolates obtained from Hillah hospitals. Isolates were identified according to API20E system and further confirmed using PCR technique. Antibiotics susceptibility was assayed by using disks diffusion method according to CLSI recommendations. All isolates revealed positive results with rapid iodometric test indicting the ability of beta lactamase production. Phenotypic detection of carbapenemase production was performed using the imipenem - EDTA disk and modified Hodeg's test (MHT). Then isolates were subjected to monoplex PCR targeting blaOXA - 51, blaOXA - 23, blaOXA - 24, blaOXA - 58, blaIMP, blaSIM blaNDM - 1, blaNDM - 2 and blaVIM genes, as well as, efflux pumps genes. One of the identified isolates (10%) was found to be imipenem, meropenem and ertapenem resistant, this isolate gave positive result with the imipenem - EDTA disk and (60%) of isolates were positive to MHT. PCR experiments showed ; all isolates were harbored blaOXA - 51 gene, four (40%) isolates were harbored blaOXA - 23 gene, three (30%) isolates were harbored blaOXA - 24 gene, four (40%) isolates were harbored blaOXA - 58 gene, five (50%) isolates were harbored blaIMP gene, six (60%) isolates were harbored blaSIM gene, two (20%) isolates were harbored blaNDM - 1 gene, four (40%) isolates were harbored blaNDM - 2 gene, while none of these isolates harbored blaVIM gene. The present findings suggest that emergence of (OXA - 23, OXA - 24, OXA - 58, IMP, SIM, NDM - 1, NDM - 2) carbapenemase producing A. baumannii clinical isolates in Hillah City hospitals. Also there are indicative appearance of efflux pump genes ; (50%) for Ade - A and Ade - B each other, (40%) for Ade - C, (80%) for all of Ade - R and Ade - S, (100%) for all of Ade - I and Ade - J, and (50%) for Ade - Y. All isolates of A. baumannii appear as MDR, while only one appear to be as PDR. The trans - mobility of resistant genes was examined by trans - conjugation experiment ; the results indicated that only blaIMP and blaOXA - 23 genes were transferred horizontally in the current study. In attempting to investigate any blaNDM gene variation the results showed some different than NCBI - Blast A. baumannii blaNDM - 1 and blaNDM - 2 it may as a unique genotyping.These results revealed that carbapenemase producing A. baumannii were detected in both phenotypic and genotypic methods (PCR). This underlies the importance of their accurate identifications and reporting to prevent the emergence of complete resistance to the most potent drugs against A. baumannii in Babylon province.

The result of laboratory culture were positive in 67 samples. Depending on their cultural, morphological and biochemical characterization of bacterial isolates : (37.31%) of them were identified as Streptococcus pyogenes bacteria and the diagnosis is confirmed by the use of Remel Rapid STR System. Whereas (34.33%) belong to S.parasanguinis, (11.94%) S.mitis, (11.94%) S.oralis and (4.48%) S.thoraltensis were identification of them are confirmed by using Vitek - 2 System also. As well as Sensitivity test for S.pyogenes cultures for some of the antibiotics done and the results revealed that all cultures were sensitive to tetracycline and chloramphenicol drugs 100%, while it was different in their sensitivity for other drugs. According to age (2 - 13) years revealed the highest percentage of infection for both male and female, however the percentage of acute and chronic tonsillitis was higher in males than females. In this study, during investigation of the antagonist action of lactic acid bacterial isolates against these pathogenic bacteria, results revealed that the method of L.acidophilus discs gave a high inhibition zones with a diameter of 11.3 mm, while L.fermentum discs yielded a high inhibition zones with a diameter of 7 mm 24 hrs following incubation in comparison with well diffusion method by using suspension of L.acidophilus produced a high inhibition zones with a diameter 7.25 mm 48 hrs after incubation. L.fermentum suspension produced a high inhibition zones with 10 mm diameter 24 hrs following incubation. Also the study included measurement of the inhibition activity for bacteriocins produced by L.acidophilus bacteria against the pathogenic bacteria S.pyogenes on nutrient agar by well diffusion method in which results revealed stability of the bacteriocins effects under different PH (4, 5, 6) with percent (100, 60, 50)% respectively for 24 hrs at higher stability and the highest stability of bacteriocins during PH was 4 with percent 100%, while it lost a lot of its activity with acidic PH less than 2 and basal pH more than 8. During the study the effect of Nacl, Kcl and MgSo4 with different concentrations (1 - 5%) with constant inhibitory effect for bacteriocins produced by L.acidophilus against pathogenic S.pyogenes, The result revealed that Nacl had little effect in inhibition zone with 1&2% concentrations. The salt MgSo4 and Kcl showed reduction in the inhibitory activity with 1, 2, 3% concentration, however the higher concentration of salt caused great reduction as 5% concentration led to loss of inhibitory activity for bacteriocins completely.Also this study showed light on the inhibitory effect of probiotics suspensions against the adhesion property of S.pyogenes after treated with L.acidophilus and L.fermentum.where the Result shown that L.acidophilus inhibit the adhesion of S.pyogenes with percent 68.92% either L.fermentum inhibit the adhesion of this pathogenic bacteria to epithelial cell with percent 30.28%. The study is consisted of showed the inhibitory action for suspensions of L.acidophilus and L.fermentum on biofilm formation by S.pyogenes, it was noticed the action of L.acidophilus in the side more than from the action of L.fermentum. During the study of the effect of suspension and filter of L.acidophilus and L.fermentum on the production of Hemolysin enzyme by S.pyogenes, it was noticed that the ability of suspension belong to L.acidophilus and L.fermentum to reduce the diameter of hemolysis zone which was beta type more than the ability of filter L.acidophilus and L.fermentum to reduce of the hemolysis zone which was beta type.
