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%). The same applies to the Amiriya district which recorded the highest percentage of people who use tap water and the lowest percentage of those using boiling water reaching ratios (41.49 %, 12.5%), respectively.

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.

المستخلص: اجريت الدراسة في مختبرات قسم علوم الحياة في كلية التربية بهدف عزل وتشخيص بعض انواع بكتريا حامض اللاكتيك ومحاولة اختبار قابلية خلاياها او النواتج الايضية منها وكذلك دراسة تاثير المستويات المختلفة من درجة الحرارة والاس الهيدروجيني في القابليـة التثبيطية لب | This work aimed to investigate the effects of some lactic acid bacteria (LAB) species (cells or their metabolic products) at different temperatures and pH levels on some soil pathogenic or toxin produced fungi species. 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

The results of geological screening and mineralization by using X - Ray Fluorescence and X - Ray - Diffraction showed that Beherii cave was mainly composed of manganese with 102 ppm comparing with other caves. While the concentration of iron and sulfur oxides were very low for all caves. The rocks of Beherii and Khanas caves were mainly composed of Dolomite (CaMg (CO3)2), Sharanish cave was composed of Calcite (CaCO3) and Dolomite with the closed ratio, while the rocks of Bejeel and Inishky were composed mainly of Calcite. The isolated bacteria in this study were identified according to cultural and morphological characteristics and biochemical tests, while the bacillus species were identified by using Microgen Bacillus Id System. Twenty two bacterial isolates were identified from total samples. There were nine (9)identified isolates from Beherii cave with 40.9% including Arthrobacter spp., Lysobacter spp., Caulobacter spp., Bacillus freudenreichii and Bacillus subtilis in with 4.5% for each isolate, while there was 18.1% of Methanogenic bacteria with its four genuses including Methanobacterium spp., Methanobrevibacter spp. Methanospirillium spp. and Methanosata spp. In Sharanish cave there was one isolate of sulfur oxidizing bacteria with 4.5 % from the total isolates. Three isolates were identified from Khanas cave included Pseudomonas spp., Xanthobacter spp., Clostridium spp. with 4.5% for each isolate. In addition, it was obtained from a cave Bejeel on six isolates included Bacillus lichiniformis, Bacillus lentus and 2 isolates of Bacillus cereus group, Streptomyces spp. and Gallionella spp. with 4.5% for each isolate and Merismopedia spp., Myxococcus Xanthus, Clostridium spp. were Isolated from Inishky cave with 4.5%for each isolate. The relation between some of bacterial species were studied by detection of the lytic ability of Lysobacter spp. and Myxococcus xanthus for Arthrobacter spp.The microbial role in caves were studied by detection of the ability of some isolated bacteria in Calcium Carbonate (calcite) formation and estimatation of calcite production, Xanthobacter spp. was the highest productive bacteria which gives0.2073 gram during 14 days comparing with other bacterial species.In addition, the effect of temperature and pH on calcite formation by Bacillus freudenreichii were studied, the results showed variation on calcite shape in 20?C and 30?C while the highest value of calcite production in pH.8 was 0.1336 gram comparing with pH.9 with 0.0190 calcite gram. The study also detected the ability of some isolated bacteria to oxidize of iron, manganese and sulfur, where Streptomyces spp. Gallionella spp. and one isolate of bacillus cereus group have shown the ability of oxidize iron on leptothrix medium while Bacillus freudenreichii, Bacillus lichinformis, Bacillus lentus, one isolate of Bacillus cereus group and Streptomyces spp. have shown the ability to the oxidize of manganese on Krumbein and Altmann Agar Medium. In addition, sulfur oxidizing bacteria has shown ability to oxidize sulfur on M.S. Agar and produce sulfuric acid as a product of the oxidation process.

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

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.

Only 51(31.875 %) Staph. epidermidis isolates were obtained during a period from September 2014 to January 2015, depending on some biochemical tests and VITEK2 system. The Staph. epidermidis was given (gram stain, catalase , urase) positive, (coagulase, manital fermentation, oxidase, motility) negative, non haemolytic to human blood with some exception, most of the strain were able to produce biofilm, and (100%), (64.70%), (74.50%) resistant to penicillin G, ampicillin, and amoxicillin respectively. The Staphylococcus species identified during study were 44 (27.5%) isolates of Staph. aureus, 5 (3.125 %) Staph. haemolyticus, 4 (2.5 %) Staph. saprophyticus, 8 (4%) isolates other Staphylococcus spp. such as Staph. hominis ssp. hominis, Staph. capatis, Staph. xylose, Staph. simulanus, Staph. lentus, and 48 (30 %) from unknown genera. To isolate bacterioghages from sewage water, several sewage water samples were assayed using plaque assay of double agar overlay as a source of Staph. epidermidis phages. The bacteriophages were described depending on plaques size and shapes, phage 1 was the most predominant and frequent in the bacterial lawn and able to infect other S. species such as S. aureus. It has been selected to study it is titer, latent, rise period, and burst size were calculated. The effect of temperature, pH , and NaCl ions on it is original titer were studied.The results revealed a gradual decreasing in the phage titer with increasing dilution number. Latent period extended to (30 minutes) , while rise period was started with (40 minutes) extending to (60 minutes) , burst size was 2.346. Each temperature at several incubation periods , pH , and NaCl ions was significantly varied depending on phage titer. The optimum temperature was 40 ° C, while the 80 ° C was represented the inhibitor temperature. L.S.D. at level (0.05) for interaction was 39.552. The pH 6.5 - 7.5 represented the optimal pH for the best phage activity while the phage titer beginning to declining in above and below this range of optimal pH, L.S.D. at level 0.05 was 17.898 , the optimum NaCl ions concentrations were (0.1 M and 0.25 M), while the titer was significantly decreased with increasing the NaCl ion concentration in the culture solution, the L.S.D. at level 0.05 was (10.696). In conclusion of this study found that Phage1 was considered as predominant phage because of their ability to infect other Staphylococci species such as Staph. aureus.

For these purpose, A total of 150 clinical specimens (skin scrapings (80), hair fragments (60) and nail clippings (10)) were collected from 100 patients (70 males&80 females) whom clinically diagnosed with dermatophytosis after attendingto the dermatology and venereal diseases centre of Mergan Teaching hospital and private clinic in Babylon city from Feb. 2014 to May 2014. T. rubrum were isolated and identified using cultural, biochemical and physiological tests. Isolates were then subjected for confirmation by PCR, genotyping using RFLP - PCR, sequencing and registration of these sequences in GeneBank for obtaining accession numbers then phylogeny. The growth conditions, were tested, in addition to, the genetic expression of proteases (exocellular protease and endocellular aminopeptidase) were determined using Real - Time PCR. Out of 150 specimens, 24 (16%) isolates were dermatophytic fungi and only 5 (20.8%) of them belong to T. rubrum. The influence of cultural conditions in growth of T. rubrum showed that the 30 ?C, pH 6, SDA medium and 7 days incubation were the optimal conditions for its growth. Proteolytic activity of isolates of T. rubrum against casein as a substrate revealed an ability to produce protease in solid and liquid media after 14 days of incubation. This activity was varies according to the type of isolate where the isolate No.1 (isolated from skin) gave a high proteolytic activity (5.6cm) in solid media and (80.1U/ml) in liquid media in comparison with other tested isolates (No.2 - No.8). on the other hands, the 9 days of incubation, 30 ?C, pH 7 and 0.5% substrate concentration were the optimal condition for proteolytic activity of these isolates. The molecular tests confirmed that all tested isolates belong to T. rubrum with amplicon size (601bp) after amplification of ITS1 primers using PCR technique. While the RFLP - PCR technique showed the presence of two genotypes (I%II) belong to T. rubrum with subgenotypes (Ia - Id) and (IIa - IId) respectively. The relative quantification of proteolytic activity (exocellular protease and endocellular aminopeptidase) produced by T. rubrum genotypes were expressed by using Real - Time PCR after amplification of the target gene of ptotease and aminopeptidase in comparison with housekeeping gene (? - actin) as a reference gene. The results showed the up - regulation of gene encoded to exocellular protease than the down - regulation of endocellular aminopeptidase produced by T. rubrum in the presence of casein as a substrate. The internal transcribed spacer 1, partial sequence, 5.8S ribosomal RNA gene and internal transcribed spacer 2, complete sequence and 28S ribosomal RNA gene, partial sequence of local isolates of T. rubrum were used for sequencing, registration in Genebank - NCBI and phylogeny. Five accession numbers were recorded and available to NCBI, EMBL in Europe and the DNA Bank of Japan. These accession numbers were : KP979787, KP979788, KP979789, KP979790, KP979791. Phylogenetic relation between local strains and world strain showed a high identicasl with T. rubrum (GQ376105.1). This is the first study in Iraq which employed sequencing, registration of sequences in Genebank - NCBI and carrying out phylogeny of local and world strains of T. rubrum.

المستخلص: تضمنت هذه الدراسة انتاج الفطر المحاري ostreatus Pleuroutus باستعمال اوساط زرعية محضرة من مخلفات صناعة محلية وما لها من اهميه من الناحية الاقتصادية كونه يعد عنصرا غذائيا مهما يحل محل البروتين الحيواني المتمثل باللحوم، وما لهذا الفطر من اهمية طبية وعلاجية ا | This study included the production of mushroom oyster Pleuroutus ostreatus by using agricultural media prepared from local industry and which has importance in the economic district it's consider important nutrition element instead of animal protein representive by meat. this fungus has importance of medical and therapeutic, the results showed existence of chemical substances concentrated in the fruiting bodies such as Galic acid and Statin and other substances. that have had an active role in reducing cholesterol in the blood as well as break the clot blood through the presence of certain types of enzymes that break down blood clotting, which may occur, the results showed when studying the mushrooms from the genetic diagnosis molecularly using the technique of the PCR to determine the type of isolation that gives the production of economically significant. Results showed the presence of gene hereditary called Osteareolysin who works with several aspects of the mushrooms which give the recipe contrast pathogenic fungi plant also this study included re - using some of the remnants of plant starch corn husks and Al - gluten and corn embryos. the remnants of Maysan sugar Factory of material Molasses and Molass Baggaz and the study of their role as carrying materials, central ferment and growth of the oyster mushroom during agricultural it on these remnants. The results of the chemical analysis of the remnants of the sugar indestrey in Maysan Molasses and Baggaz and waste plant starch in Al - hashemeyeh / Babylon Al - Baggaz and yellow corn straw showed that molasses substance was contain the amount of sugars which sometimes reach to 41%, that making it as a good base of food to mushroom. When added molasses at different levels 2, 4, 6% to the central media the study showed a positive relationship between the levels of molasses and the radial growth of the oyster mushroom. The concentrations 25, 50, 100% of the leaky innate showed ability Tdhadah high - fungal plant pathogen (Aspergillus niger, Aspergillus flavus, Fusarium solani, Stymphllium sp., Penicillium sp.) Antigonsim when studying the negative ability of the fungus. The results showed a significant increasing in the growth standards and gaining characteristics of the oyster mushroom in the mass production of fruiting bodies called the gaining total according to the wet weight and it was higher production on corn husks and pomace dates 761.89, 735.13 g /kg of media and concentration of molasses 6%. when measuring efficiency of the fungus to product the largest amount of fruiting bodies observed that the middle pea - corn husks and pomace dates gave a larger amount of the remaining media and a concentration of 6% 76.18, 73.51%, have been affected by the weights of pods fungal change is another factor which affected by rates of molasses. The results were closely between nutrition media but nevertheless observed superiority of Corn husks and Pomace dates on the rest of media (15.04, 13.77)by using 6% concentration of molasses. when calculate the lengths of the necks of the body fruiting because of the great importance in a statement recipes - gaining produced and influenced by user medai - aligned and concentrations of molasses, as there were differences moral at all concentrations of molasses, when calculating the percentage of dry matter increased significantly increase the concentration of molasses and all concentrations compared with a comparison of strew wheat, which amounted to 12.16% when adding 2% molasses observed the emergence of highly significant differences between treatments and compared with control treatment, which gave treatment of Pomace dates highest rates, followed by corn husks and corn embryo and Al - gluten and Baggaz 8.21, 9.00, 9.28, 9.29%, respectively. For the purpose of obtaining material efficient in maintaining the objects fruiting intact throughout the storage period tested preservatives (such as Sorbic acid and black pepper) and concentrations 40.20g / l of articles in a row leads to prolong longevity reservoir simulation of the objects fruiting and maintain the quality characteristics of the objects fruiting. The results showed that the addition of material to the feeder molass medai AGRO of oyster mushroom had been increased the proportion of protein in the fruiting bodies, either with respect to calculate the proportion of carbohydrates had been found that the percentage of carbohydrates are associated with a high positive correlation relationship between the concentration of molasses and the different transactions that were used in the experiment. The oils were represented less than what can be had reached attribute to 0%. Well conducted safety checks the health of the mushroom oyster and the results were that the fungus free of toxins by anatomy organic to members liver, kidney and intestines and by the standards of blood physiological mice tested. And the importance of this project calculated the economic viability and profits and revenue obtained from such a project.

المستخلص: تم التحري عن بكتريا السالمونيلا في 520 عينة من الاغذية المحلية في مدينة تكريت, وجدت هذه البكتريا في 26 عينة (5%), كانت اعلى نسبة لتواجدها في عينات اللحوم المثرومة (2.5%) والتي تمثل 16.25% من العينات الكلية للحوم المثرومة المدروسة.عزلت السالمونيلا من عي | The presence of Salmonella spp. was investigated in 520 local food samples in Tikrit city, Salmonella was found in 26 samples (5%), with the highest presence in minced meat (2.5%) which was represented 16.25% of all minced meat samples. Salmonella was isolated from chicken's meat at a percentage of 3.75%, and same percentages for meat slices samples, egg cortex and chicken's blood represented 5% for each one, and isolated too from vegetables and cheese at a percentage of 2.5% for each one. No Salmonella has been detected from sweet, yoghurt and egg content. Six Salmonella species were isolated, S. typhimurium was to be the most frequent and represented 42.30% of positive samples, then S. enteritidis and S. anatum in 34.61% and 11.53% respectively, but S. agona, S. typhi and S. arizona existed in a percentage about 3.84% for each one. Also, all the isolated species showed their own serological formula. The selective medium Tetrathionate broth (TTB) was found to be superior for isolation of Salmonella than Selenite cystine broth (SCB), the former positivity was 96.2% and 88.5% respectively. For test of better selective medium for isolation, TTB was found to be more suitable for isolation of S. anatum, while SCB was better for isolation of S. arizona.All the six isolated Salmonella species showed high sensitivity to Ciprofloxacin (5?g) and moderately sensitive to Chloramphenicol (30?g), while they showed high resistance to three antibiotics Amoxicillin (30?g), Nalidixic acid (30?g) and Pipracillin (100?g). They showed resistance with different percentages to the other tested antibiotics : Ampicillin (10?g), Gentamicin (10?g), Streptomycin (10?g), Tetracycline (30?g) and Trimethoprim (25?g).
