المستخلص: The present study aimed to search for safe and effective antifungal agents through investigation of the phytochemical characterization and bioactive properties of medicinal plants (Pimpinella anisum essential oil and Moringa oleifera and Malva sylvestris leaf extracts) and their effect on gene expression of keratinases produced by T. rubrum using Real Time PCR.Phytochemical analysis of active materials of P. anisum essential oil and M. oleifera leaf extracts were carried out, through TLC accompanied autobiography, high performance liquid chromatography (HPLC) and GC - MS analyses were proceeded to relate the chemical profile with their antifungal activity. Also, the cytotoxic effects of active compound and crude extract for both plant extracts were determined using MTT (3 - (4,5 - dimethylthiazol - 2 - yl) - 2,5 - diphenyltetrazolium bromide dye) assay. Screening the antifungal activity of Pimpinella anisum essential oil, Moringa oleifera leaf extracts and four traditional antifungal agents against growth and development of two strains of T. rubrum differed in their virulence were conducted. MIC for crud extracts and antifungal agent were also determined using microdilution plate, moreover, the effects of crud extracts and active compounds on gene expression was evaluated.Qualitative TLC, HPLC analysis for the anise essential oil extract revealed the presence of anethole which was identified as a main volatile compound in this extract which was identified as anethole. GC - MS analysis also revealed that trans - anethole is the major compound (96.8%), then Himachalene (1.84%), other components were also present but less than 1% e.g. Estragole, cyclohexene and 2 - Methoxy - 5 - (1 - propenyl) phenol. On the other hand, LC - MS analysis were showed the existence of that keratinase inhibitor (extracted from Moringa oleifera leaf)IICryptochlorogenicacid (C16H18O9), Astragalin (C21H20O11), so the presences of these compounds reflected the inhibitory effects on keratinase enzyme.The results upon screening, revealed that the anise oil inhibited both strains of T. rubrum, since the growth inhibition for first strain were 21, 30 and 39 mm at 15.6, 31.2 and 62.5 μl/ml respectively, while in second strain were 24, 32 and 39 mm at 15.6, 31.2 and 62.5 μl/ml respectively. The tested strains of this fungus revealed substantial sensitivity pattern toward crude extract of essential oil and anethole as well. Results showed that there was considerable growth inhibition for both strains of T. rubrum at minimal inhibitory concentrations (MIC) between 15.6 μg/mL for crude oil and 7.5 μg/mL for anethole. The inhibition in radial growth due to the effect of anise essential oil increased from 56% at 3rd day to 86% at the 7th day. Sporulation was substantially decreased by anise oil treatment. Anise oil was significantly inhibited conidial germination for both strains. Treatment with anise oil induced morphological changes in the conidial group where the conidia were absent in treated sample. Protease inhibitor isolated from mature leaves of M. oleifera showed great ability to inhibit keratinase activity of T. rubrum.MTT assay revealed that anethole is safe as phototherapeutic agents, when it is having no effects on normal cell, but shown anticancer activity against cancer cell.Anise oil, anethole, M. oleifera crud inhibitor, Cryptochlorogenic acid and Astragalin showed high inhibitory effects on gene expression of keratinase enzyme in both strains of T. rubrum KP979791 and KP979787.

Carbohydrate fermentation test was used to distinguish the species of Bifidobacterium, the results revealed that the B.bifidum is more predominant than the other species; B.thermoacidophilum, B.adolescentis, B.breve, B.longum. Antibiotics susceptibility test to Staphylococcus aureus using antibiotic disc diffusion assay showed that Methicillin Resistant Staphylococcus aureus formed 70% and 30% of isolates were sensitive to the same antibiotics, also the ability of MRSA isolates to produce Biofilm and Slime layer was investigated by tube method and Congo red agar, then 10 isolates of Staphylococcus aureus were selected as efficient isolates according to the resistance of Methicillin and the high ability to produce biofilm and Slime layer. The antagonistic activity of Bifidobacterium spp was extracted and tested against these MRSA isolates, the results showed that the most isolates of Bifidobacterium spp were effective against Methicillin Resistant Staphylococcus aureus (MRSA), as well as the inhibition of growth and formation of Slime layer by using the wells and disc diffusion agar assay. The inhibition zone was between (10 - 30)mm, and the ability of bacteriocin production of Bifidobacterium spp against MRSA have been conducted by well diffusion broth method, B.bifidum3 was greater than other species in producing bacteriocin with asignificant increase (P<0.05). Furthermore the impact of bacteriocin production to inhibit the development and formation of biofilm was investigated, the results showed that the bacteriocin has ahigh activity against MRSA. The bacteriocidal and bacteriostatic effect of bacteriocin was conducted by using spectrophotometer, the results showed that these effects were bacteriostatic in the beginning of the growth MRSA while it was lethal during other time and 40 minutes is the period needed for killing MRSA bacteria.

During the period from October 2013 to February 2014, a total of 140 oral swab were collected from immunocompromised patients with attending to the three center in AL - Sadder Medical City (Oncology center and kidney center and Center for Diabetes and Endocrinology).In AL - Najaf Governorate, the samples were collected as following : - 110 mouth swabs from patients suffering from leukemia, prostate, stomach and bowel cancer, also 10 mouth swabs from kidney transplant patients and 20 mouth swabs from diabetes. The percentage of female to male was as following, female (86) 64(72.7%) infected, 22(42.3%) uninfected and male (54) 30(57.7%) uninfected, 24(27.3%) infected, with age range between (5 - 64) years. In this study, the results show that the incidence of candidiasis in women was higher than the male also the most cases of candidiasis in patients age range between (45 - 54) years. The results of the present study reveal that the prevalence of oral candidiasis from patient with cancer was more than diabetes & kidney transplant patients which was 72(81.18%), 12(13.65%) & 4(4.54%) respectively. When culturing oral samples on the primary isolation media Sabouroud dextrose agar (SDA) and the secondary media on CHROM agar, The results reveal the presence of 88 isolates belong to Candida spp.which include : - 42 (47.68%) belong to Candida albicans, 20 (22.72%) belong to Candida. dubliniensis, 18 (20.5%)belong to Candida krusei, 6 (6.8%) belong to Candida glabrata & 2 (2.3%) belong to Candida parapsilosis. According to this result, Candida albicans was found the most frequently isolated species and the occurrence of the other non - albicans isolates such as Candida dubliniensis and which followed Candida albicans in frequency of the isolates in oral candidiasis. In this study, the ability of C.albicans & non - albicans was tested to produce some virulence factors such as production of enzymes phospholipase, lipase, germ tube, chlamydospore & biofilms when culturing Candida spp. on different media. The results of the culture show that Candida albicans produces all virulence factor included germ tube, chlamydospore, biofilms & phospholipase. Some species share several phenotypic characteristics ability to produce enzymes of phospholipase such as C.krusei while C.dubliniensis produce chlamydospore, when culturing in the Casein agar & produce biofilms, In addition the molecular tests to was used for Candida albicans confirm the ability to secreted aspartyl proteinase (ASP2). This study showed the amplified from the Candida spp. as following : - C.albicans 306 bp, C.glabrata 594 bp, C.parapsliosis 387 bp, C.krusei 651 bp & C.dubliniensis 451 bp.

المستخلص: Between September and November 2013 a total of 140 urine specimens obtained from patients in Al - Kadhmiah Teaching Hospital, Ibn - Al Naffees Teaching Hospital, and Educational Laboratories in Medical city. These midstream urine specimens were obtained from patients clinically suspected to have urinary tract infection (UTI) in sterilized containers. All specimens were processed immediately after collection.A total number of 140 specimens of mid - stream urine were collected from patients suffering urinary tract infection symptoms. These isolates were obtained from 41 male and 99 female patients. They were distributed in the age group of 5 - 60 years old. All specimens were identified using biochemical tests and API 20 E system. 60 (42.85%) of urine specimens was Escherichia coli and 15(10.71%) of specimens growth was Klebsiella spp. and 25(17.85%) growth was Proteus spp. and 40 (28.57%) was G+ve bacteria.The adherence ability of E.coli isolates were evaluated by using Congo red agar and detected their ability to produce biofilm by using methylene blue staining technique in polystyrene microtiter plates and then Optical density was determined at 580 nm.All sixty isolates of E.coli were grown on Congo red agar medium to detect their adherence ability. Twenty (33.3%) isolates were given negative result by forming pink colonies on congo red agar, were as, forty (66.6%) isolates were given positive result by forming black colonies with a dry crystalline. Three isolates give strong results E.coli (13, 8, and 40). Consistency indicated biofilm production by microtiter plate. E. coli 40 which isolated produced the thickest biofilm (O.D. : =3.17).Type 1 fimbriae expression by E.coli 40 isolate was detected by mannose - resistant hemagglutination (MRHA) of human blood group (O) IRBCs in the presence of 2% D - mannose. The isolate showed strong MRHA characteristics of type 1 fimbriae under microscope (40x). The E.coli E.40isolate which produced the thickest biofilm and gave strong MRHA was elected to be the source of type 1 fimbriae.Type 1 fimbriae was extracted by heating and mechanical shearing and partially purified by Ultracentrifugation (48, 000xg for 3hrs). SDS - PAGE with a molecular weight 20, 000 Dalton.Anti - type1 fimbriae antisera were prepared in rabbits. The specificity and titration of anti - type1fimbriae antibodies were determined using IgG protein by radial immunodiffusion plate and bacterial agglutination. IgG antibodies to fimbriae type 1 were also detected in rabbit sera from immunized rabbit and non - immunized. Immunized rabbit test 1 had increases in Fim1 - specific IgG antibodies (9.5) mg/dl. Immunized rabbit test 2 had increases in Fim1 - specific IgG antibodies (8.6) mg/dl. The non - immunized rabbit had no increase in absolute IgG antibodies to Fim1.The antisera agglutinated bacterial cells up to 1/80 dilution confirming the presence and titer of specific antibodies against type1 fimbriae.The microtiter plate method was applied to estimate the role of the prepared anti - type1fimbriae antibodies in reducing the biofilim formation by E.coli. Prevention of bacterial adherence and subsequent biofilm formation to polystyrene microtiter plate was studied by employing different dilutions (1/10, 1/20, 1/40, 1/80, 1/160, 1/320, 1/640) of rabbit sera containing anti - type 1 fimbriae antibodies. The maximum inhibition of biofilm formation in terms of optical density (580 nm) was found in lowest dilution (1/10) (highest concentration of Abs). However, the minimum inhibition was observed in highest dilution of rabbit antisera (1/640) (lowest concentration of Abs). Here the inhibition occurs in a dose dependent manner as the biofilm formation increased dramatically with increasing in antisera dilution. The results also showed that there is a significant difference(P<0.05) among data treated with sera and data without sera and among serial dilutions.General urine examination and culture for urine that absorbed from test 2 and control was done (GUE) show that pus cell in urine was (1 - 2/HPF). There was no growth of bacteria in urine culture.The Histological section show that the Control and test 1 rabbit (have been immunized with fimbriae and adjuvant and injected with E.coli intra muscular) and Test 2rabbit (that has been immunized with fimbriae and adjuvant and injected with E.coli directly in bladder has normal epithelial cells and mucosa.

A total of 800 of urine samples were taken from patient suffering from urinary tract infections had been collected during a period from February, to September of 2012, from the hospitals of AL - Najaf province. All the samples were cultured on MacConkey agar. From those 300 samples gave positive bacterial growth , 250 were lactose fermentative isolates, which were submitted to conventional tests including IMVIC and motility tests ultimately lactose fermentative, non motile isolates were candidate to Vitek 2 system to confirm the identification. the results revealed that there were 42 (16.8%) of isolates identified as Klebsiellae represented by Klebsiella pnumoniae ssp pneumoniae, 9(3.6%) of isolates diagnosed as Raoultella ornithinolytica, and 1(0.4%) for both K. pnumoniae ssp.ozeanae and Raoultella planticola. Screening tests were performed , disk diffusion test revealed different pattern of resistance, screening of ESBLS by MacConkey agar medium supplemented with 2 mg /l of Ceftazidime showed that 31 (58.5%) of isolates were initially ESBLS producers.Phenotypes confirmatory tests were conducted to different classes of antimicrobial agents, Disk synergism test revealed that 20(37.74%) of isolates were ESBLS positive, while Disk combination test by Ceftazidime + clav and Cefepime + clav revealed that 28(52.83%) and 43(81.13%) were ESBLS producers respectively, disk replacement test pointed that positive isolates were 26(49%), vitek2 system revealed 33(62%) of isolates were ESBLS producers.Imipenem - Ceftazidime antagonism test revealed that there was no isolate produce induced AmpC beta - lactamase, AmpC disc test revealed that no one of isolates were AmpC producer.The result of MHT(Modified Hodge test) revealed that all isolates were not Carbapenemases producers. Molecular study of different antimicrobial resistance genes were performed, the results reveald high percent of occurence as follow : blaTEM genes (90.6%), blaSHV gene(81.13%), blaCTX - M genes (88.6%), sul genes (88.6%), aac(6')Ib - cr genes (84.9%) and qnr - B genes (41.5%).the study also highlighted an association between studied genes. Finally many attempts to study of gene transfer by conjugation were conducted but all of them were failed, except one isolate (No. 5) was succeeded with frequency of conjugation (0.5×10 - 7). This study concluded that there were high prevalence of some plasmid mediated genes of isolates with clear multi gene resistance patterns as compared with some other genes which propose the high selective pressure of these genes and isolates might acquired resistance by mobile elements such as plasmids and integrons.

In this study five hundreds thirty four samples of urine and wounds from patients with diabetes and healthy were collected from both sexes and all ages to isolation and identification of pathogenic bacteria by morphological, cultural and biochemical characteristics then determination of virulence factors and genetic variation between dominant type depending on the isolating source and the type of infection in diabetic patients. The counts of urinary tract infections and wound infection in non _diabetic patients were 118 and 52 respectively.The percentage of positive isolation of bacteria for both of them were 44, and 38.4% respectively and from the same patients with urinary tract Infections and wounds and Insulin Depended Diabetes (IDD) patients were 158 and 68 samples respectively and the percentage of bacterial isolation were at 78.5 and 67.6% respectively. The patients with Insulin Non - dependent Diabetes (INDD) were 69 and 42 samples, where positive isolates from bacteria were 75 and 71.4% respectively. The infections females from the Healthy and Diabetes Patients that (IDD) or (INDD) were larger than that of the males patients and with the same state with the wounds infections state for (IDD) patients, whereas the rate was smaller than of males for wounds infections to patients with the other diabetes infections type. The age group between 41 - 60 years was the larger percentage with all infections, except with wounds infections to (INDD) patients, while the age group between 16 - 40 years was the larger, and the infections were the largest means in the Winter and Autumn compare the other seasons.The higher rate of bacteria that isolated from patients with Urinary Tract Infections was Escherichia coli then other types like Citrobacter diversus , Proteus mirabilis, Morganella morganii, and Enterobacter aerogenes. The larger rate of bacteria in patients with diabetes and wounds Infections was Escherichia coli then Citrobacter diversus, Proteus mirabilis, Enterobacter aerogenes, Morganella morganii and Staphylococcus aureus. The rate of diabetes infections with urinary tract infections and wounds increased in winter and autumn seasons more than of summer and spring seasons, Most bacterial isolates where sensitive for chloramphenicol.Other antibiotics were highly variable in their ability to inhibit bacterial isolates.the bacterial isolates were different in their ability to produce virulence factors, the diabetes infections was the reason of increase the variation in their ability to produce that virulence factor and the bacteria that isolated from diabetes patients produced haemolysine factor and capsule.PCR technique was used to show the genetic variations for the more repeats bacterial isolates isolated from all sources infections and used the Specific Primers (KPSMT II) group II capsule, (CNF1) Cytotoxic Necrotizing factor, (CNFs) and (HLY A) haemolysine, the bands appeared after electrophoresis to represent the used Primers, one band was appeared in the sample of diabetes Patients with Urinary Tract Infections(KPSMT II) at molecular weight 270 bp, and one band appeared in the sample of diabetes with urinary tract infections for Primer (HLY A) and it is molecular weight was 177 bp. One band appeared in the sample of diabetes patients for the primer (CNF1)hg with Wound Infections and it is molecular weight 450 bp, and there is not any band in the Primer (CNFs).

المستخلص: اجريت الدراسة الحالية بهدف عزل وتشخيص المكورات المعوية البرازية Enterococcus faecalis من مصادر سريرية مختلفة، وتقييم التغيرات المظهرية والافات المرضية في بعض اعضاء الفئران البيض السويسرية المصابة تجريبيا لذا تضمنت هذه الدراسة محورين رئيسين هما : الجانب ال | The present study was conducted to isolate and diagnose an Enterococcus faecalis which are isolated from different clinical sources, and evaluate the appearance changes and pathological lesions in some Swiss white mice organs which are infected experimentally, so this study deals with two main aspects : The bacteriological type : The results obtained may be summarized as follows : - The total number of (310) clinical samples were collected from Baquba Educational Hospital and Al - Batol Hospital for Maternity and Children in Baquba city from the beginning of March to the end of September (2009) with various ages and from both sexes, including (82) urine samples from patients with urinary tract infections, (46) vaginal swab from infection of female reproduction system, (45) surgical wound swabs, (38) stool sample from patients with abdominal pains and diarrhea, (32) throat swabs from tonsillitis patients, (25) middle ear swabs, (22) burn swabs, and (20) blood sample from patients with bacteremia and prosthetic valvular heart diseases. The isolates diagnose depended on the cultural and microscobial characteristics and biochemical tests, serological diagnosis according to Lancefield method and assertion diagnosis according to (API - 20 Strep) was done to find (32) isolates of Enterococcus : (28) isolates of E. faecalis (87.5%), (3) isolates of E. faecium (9.4%) and one isolate of E.gallinarum (3.1%). - The sensitivity of E. faecalis was tested against (23) different antibiotics. The isolates showed resistance of about (100%) against Aztreonam, Amikacin, Co - Trimoxazole, Cephalexin and Cefotaxime, while the isolates were sensitive about (100%) against Amoxicillin, Nitrofurantoin, Imipenem and Ampicillin, while they showed a various resistance to another antibiotics involved in this study. - The ability of the isolates for producing the Beta - lactamase enzymes was tested by the standard rapid iodometric method. The results showed the disability of these isolates for producing the Beta - lactamase enzymes. - The production ability of E. faecalis for some virulence factors was evaluated. The results showed the ability of these isolates of adherence to the uroepithelial cells of human's urinary system were (93%), and (82.1%) were bacteriocin producer, and (28.6%) were hemolysin producer, and (43%) were gelatinase producer, and (10.7%) were lipase producer, and (35.7%) were capsule producer, and (14.3%) were cytolysin producer, while none of the isolates under the study showed the ability of haemagglutination.Histopathology type : (4.6 x 106) cell / ml concentration of the bacterial suspension of E. faecalis was used orally on mice and histopathological changes were examined after (3, 5, 7, 14) days of infection, which revealed the ability of bacteria for colonization and causing pathological lesions and many histological changes in the liver, kidney, small intestine and hearts of these animals. The damage in the animal tissues of the second group (treated with Streptomycin and EFU10) was more than that in the third group (treated with Streptomycin and EFS14), and fourth group (treated with EFU10 only). Generaly, the most important histopathological changes were the necrosis in some areas, and infiltration of inflammatory cells in infected tissues. These pathological lesions cause damage and decompose of tissues with distortion of their morphologies.

The epidemiologically which is main to determine the rates of infection as registered in some district of Diyala province in according to the age, sex, and the month of the year so according to the environmental conditions : - 7200 samples of blood collected from many different ages persons from different districts in Diyala. (3009 males, 4011 females) are examined. The study shows a positive cases of 607 distributed among the districts including (Jalawlaa, Bani Saa'd, Baladruz, Baquba, Alodeim amd DeliAbbas) these register a highest percentage of infection in Jalawlaa sub - district about 12.8% and less percentage of infection are in Baquba about 1.3% whiel is register highest percentage of in infection were (>1 - 5) years about 13.2% and lower percentage infection (<5 - 10) years wuth rate 2.4% so the groups of ages (25 - 30) years didn't appear any infections. according to the gender the males are high from the females whom effected with this disease the number of males (432) case with rate 71, 1%. The number of infected females about 175 cases with rate 28.8%.while in the month of years were the male infection are a highest infection in January - 2012, but did not register any infection in (June and July). The environmental condition infective in prevalence the disease between the people whom resident the houses which breed the animals inside, the number of infections are 245 cases from 607 positive cases with rate 40.3%. This was the low rate 4.9% from the infected people because of rats in their hoses. which didn't kill them. 2. The comparison of diagnostic methods of clinical test, laboratory test and serological test, with the molecular methods from the direction of sensitivity and specificity, The studies results appeared the importance of clinical test subtle in case of a similar cases depend on the clinical symptoms there are a highest cases from clinical test that the children suffering from liver magle their number are 176 cases the rate 80.36%, but the lowest cases of clinical test are 59.19% whom suffered from a skin pallor and black. The laboratory tests appeared the blood picture through testing the 350cases whom suspicion in their infection with leishmaniasis, the number of whom suffering from the lower of WBC 73 with rate 34.2%, while the low cases are 6 with rate 2.82% from whom suffering from hipper ESR, but the serological test was IFAT, Dipsrtick, spotkala - azor, ELISA, KA tex LATEX. Diagnostic infection leishmaniasis a best in diagnostic disease is dipstick test it's sensitivity are 95%, but it's specificity 100% but the lowest is the test of LATEX, it's sensitivity 75% and specificity 80%.3. The Molecular methods : PCR technique test clear recently the new highest sensitivity in diagnosis when the number of the parasite are a little in the blood in the infections peoples whom choose in random way. when testing 100 samples of DNA from the infection with cutaneous and visceral leishmaniasis, the number of infected male are 73, But the number of infected females are 27 with leishmaniasis. and studying the relation between PCR diagnosis according to the sex, age, district and environment condition, so as the recognize between the species of the parasite from the sequence Nitrogen basics with number in each species, (the species are L.donovani, L.infantum, L.tropica, L.major) so recognize the vector insect sand fly Morphology by key classification (ph.alexandri, ph.papatasi Ph.sergentasi, and sqauanlpleuris).

The vaginal examinations were done by gynecologist, two high vaginal swabs were taken from (250) women & a cervical swab from some women with vaginal discharge. General urine examination & blood group with Rh factor were performed for each woman with vaginal discharge. Direct microscopic examination, staining & culture of swabs were performed on different methods for diagnosis of Trichomonas vaginalis, followed to diagnose Candida albicans, Neisseria gonorrhoeae, Chlamydia trachomatis & Treponema pallidum as well as some other bacterial groups. The rate of Trichomonas vaginalis was (2.8%) & Neisseria gonorrhoeae (0.8%), while no Chlamydia trachomatis & Treponema pallidum recorded in this study. The highest rate of Trichomonas vaginalis was among the age group between 15 - 29 years (3.6%), the rate of Trichomonas vaginalis infection was higher among illiterate (5.7%) than educated ones. The highest rate of Trichomonas vaginalis was recorded among those with blood group O & Rh (+ve) (3.8%). The same result was found regarding other microorganisms in both sexes. Statistically the results were not significant.The rate of infections in females was higher than males in all infection except Neisseria gonorrhoeae was recorded highest rate in males(35%). The percentage of mixed infections with Trichomonas vaginalis was Candida albicans (1.6%) & B - hemolytic streptococcus (0.4%). The maximum infections rate in vaginal swabs were Staphylococcus aureus (42.3%) & lowest rate of Neisseria gonorrhoeae (2%). Regarding the distribution of microorganisms isolated from urine samples of females suffering from vaginal discharges, the highest rate of infection was Eschirechia coli (22.2%) & lowest rate of Neisseria gonorrhoeae (2%) respectively. The rate of isolated microorganisms from urethral discharge of males were Neisseria gonorrhoeae (35%) & Escherichia coli (5%). Antibiotics Ciprofloxacin & Amikacin showed good inhibition activity against all pathogenic microorganisms. Regarding the effect of different concentration of metronidazole & medical herbs to the Trichomonas vaginalis invitro, metronidazole showed clear effective inhibition at concentration (1.25%) during 24 hours. The inhibitory effect of Zea mays (both alcoholic & watery extractions) was greater than Apium graveolens & Foeniculum vulgare. At concentration (2.5% & 5%) of Zea mays in both extractions was almost identical to metronidazole. Six solvents were used by thin layer chromatography (TLC) in order to separate alcoholic & watery extraction of medical herbs, only three of them A, B & F gave good results in separating herbal extraction with differing in its component. By measuring relative flow rate (Rƒ) of all compounds that separated and determind. The chemical compounds of each herbal extract were established & included alkaloids, flavonieds, amines, pigments, oils, carbohydrates, phenols, purines & tanines.

المستخلص: تضمنت الدراسة الحالية عزل وتشخيص (19) نوع من السيانوبكتريا من عينات مياه وتربة طينية ومن الصخور من (5) خمسة مواقع في مدينة تكريت ضمن محافظة صلاح الدين، وقد تم اختيار ثلاثة انواع من هذه السيانوبكتريا وهي : Anabaena oryzae, Nostoc linckia, Anabaena laxa اعتم | The current study included Isolation and Identification of (19) species of cyanobacteria from water, clay soil and rocks samples, collected from (5) sites in Tikrit, salah Al - den province. Three species were chosen each species represent the environment which collected from it. These species were Anabaena oryzae, Nostoc linckia, Anabaena laxa. The effects of some environment factors on growth and biological products quantity has been studied in the three species above. The effects of the temperature showed that 26°C was the best for growth and biological products quantity than 16°C and 36°C. While the pH effects showed that pH 7.6 was the best for growth and biological products quantity than pH 6.6, 8.6. Three light intensities were used 1250, 2500, 5000 lux were used. The results showed that the light intensity of 2500 lux was the best for daily growth and quantity of extracted biological products. While the study of the effects of addition of macronutrient and micronutrient to Asm - 1 media which used for culturing of the three species of cyanobacteria by replacement of NaCl by NaNO3 in the medium, showed that there is an increase in daily growth and quantity of extracts of biological extracts, also the addition of FeSO4.7H2O and NaNO3 together showed further increase of daily growth and biological extracts quantity. The biological products has been identificated by HPLC - MS, IR and NMR. The results showed the presence of the neurotoxin Anatoxin - a and the hepatic toxin Microcystin in its various forms MCYST - LAba, MCYST - YM(O), [D - Asp3, Dha7]MCYST - LR and MCYST - YA in the biological products of Anabaena oryzae. The results also showed the presence of the hepatic toxin MCYST - YM(O) and [D - Asp3, Dha7]MCYST - LR in the extracts of the two spices of cyanobacteria Nostoc linckia and Anabaena laxa.The results also showed that the Muller Hinton Agar media is better than the Blood Agar media in testing the activity of these extracts in inhibition of the pathogenic bacteria, the method of holes is better than saturated discs, and the solvent DMSO (Di - Methyl Sulpho Oxide) is the better in testing of biological activities, while the filtrate of cyanobacteria did not shown any activity for inhibition of the pathogenic bacteria which include : Escherichia coli, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus Vulgaris, Staphylococcus aureus. The results showed the high capability of inhibition in concentrations of 1000, 2000, 3000 µg/ml of the extracts of the cyanobacteria Anabaena oryzae, Nostoc linckia and Anabaena laxa on the above pathogenic bacteria and some times more efficient than antibiotics used for comparison, and the concentration 3000 µg/ml was the most effective.The effects of biological extracts of the three species in concentrations of (1000, 2000, 3000) µg/kg of body weight on tested albino mice, using injection and feeding methods, was studied. The results showed poisoning nervous symptom for the first few hours, while the results showed hepatic poisoning symptom on the dissecting animals. The anatomic symptoms included changes the colour of the liver to darkening and appearance of necrosis, in addition to becoming lobbed and swollen some times with bleeding.While the poisoning effects on dissecting tissues of livers of the animals showed a simple swollen and some times assured in all of the liver accompanying with increase in growth and cell division, as well as increases in lymphatic cells inside the tissue and in general in liver tissue. The lymphocyte seemed bigger than for normal cell with multi - nuclei in white blood and increase in cell size and destruction of liver tissue. Nostoc linckia was the greater urging for cell division consequently probably more induce of cancer in the liver of the animals, while the biological product of Anabaena laxa showed more poisonous for liver cell than the biological products of Anabaena oryzae, the least effective in cytotoxic and urging cancer cell in liver of the animals.

These samples include : (75) Urine, (28) stool, (28) of wound swabs and (9) sputum samples.The incidence of nosocomial infection was (45.7%) of them, urinary tract infections were (50.7%) from (75) samples, followed by wound infections (42.9%) from (28) samples, gastrointestinal infections (39.3%) from (28) samples then pneumonia (33.3%) from (9) samples the nosocomial infections were more common in females and age group 51 - 89 years. Different bacterial species were isolated in this study and the results showed that the most commonly isolated type was Citrobacter koseri in a proporation (21%) of urinary tract infections, followed by the following bacterial species : Escherichia coli (15.7%), Staphylococcus schleiferi (10.5%) , Staphylococcus epidermidis (7, 8%), Proteus vulgaris, Staphylococcus saprophytica, Klebsiella ozaenae, Klebsiella ornithindytica in aproportion (5.2%) for each, Enterobacter aerogenes, Providencia stuartii, Staphylococcus warneri, Staphylococcus aureus, Proteus mirabilis in aproportion (2.6%) for each.Citro. koseri were also the most common in wound infections (25%), followed by the following bacterial species : E.coli (16.6%), P.mirabilis (16.6%), Staph.schleiferi, P.vulgaris, Prov.stuartii and Prov.rettgeri in aproportion (8.3%) for each. Citro.koseri were also the most common in the gastrointestinal tract infections in a proporation (36.3%), followed by E.coli (18.1%), S.flexneri (18.1%), P.mirabilisc, Prov.stuartii, Prov.alcalifaciens in a proporation (9%) for each. . While Strept.pneumoniae was the most common(66.7%) in penemonia cases followed by K.pneumoniae (33.3%).The isolated bacteria were tested for antibiotics susceptibility and it has been found that most of these isolates showed high resistance to the studied antibiotics other than Prov. Stuartti was sensitive to all antibiotics except of Rifampicin and Tetracycline. As well as bacterial species belonging to the genus Staphylococcus were sensitive to Amikacin, Staph.aureus was also sensitive to Nitrofurantoin while Staph.warneri was also sensitive to Ciprofloxacin and Nitrofurantoin also Enterobacter aerogenes was resistant to all antibiotics except for Ciprofloxacin and Nitrofuratoin. Eleven of most commonly isolated bacteria which were multidrug resistant were chosen for the curing experiments using SDS to study the relationship of their plasmids with resistant to antibiotics. The results showed that the cured cells of E.coli lost their resistance to Tetracycline Ciprofloxacin and Cefotaxime which Citro.koseri lost their resistance to Tetracycline while K. ornithinolytica lost resistance to both antibiotics Tetracycline and Ciprofloxacin either P.mirabilis lost resistance only to tetracyclin as well as Strept.pneumoniae lost their resistance to Cefotaxime, tracycline and Ampicillin. Which may mean that the genes responsible for resistance to these antibiotics are located on plasmids as proven by the results of electrophoresis.Electrophoresis results also showed that all studied bacterial isolates had the same plasmid profile which may regarded as an epidemiological pointer that plasmids are conjugative which have the ability to transfer antibiotic resistance to other bacterial strains of the same species or to other different bacterial species.

The isolation and identification of yeast isolates were done based on their morphological, Cultural and biochemical tests in addition to use the confirmatory systems such as the growth on Chrom Agar candida, Api Candida and Tobacco Agar medium to distinguish C.albicans from other yeast spp. Also, some virulence factors of C.albicans such germ tube formation, chlamydospores production, growth at of 45 c and resistance to cycloheximide were detected. The antibiotics sensitivity test was used in two method (disk diffusion & dilution) to determine the sensitive, trailing growth, resistance isolates and minimal inhibitory concentration (MICs) toward azole agents. The qRT - PCR was used to detect the relative quantitative of Erg11 gene expression and its relationship with resistance to azole and emergence of trailing growth phenomena in the presence of Fluconazoles and ketoconazole. The isolation and identification results revealed that the isolation percent of C.albicans was 47.05 % incomparison with other Candida species that were 15.3%, 11.76 %, 8.23 % and 5.9 % for C.krusi, C.dubliniensis, C.tropicalis, C. parapsilasis and C.glabrata , respectively. The antibiotic susceptibity tests of C.albicans showed the presence of resistance precent (38.89%) to fluconazole and the most of sensitive isolates revealed a trailing growth phenomena in the zone of growth inhibition of floconazole in a ratio 55.56%. While the resistance percent to ketoconazole was 27.78 % and the sensitive isolates showed the trailing growth in a ratio (38.89%). The statistical analysis showed a significant differences (P <0.05) among tested treatments. The MICs values of fluconazole against C.albicans isolates were 8, 16, and 64 Mg/ml for sensitive isolates and were 0.125 and 0.5 Mg /ml for resistance isolates and the trailing growth phenomena occurred at MICs value ? 8 Mg/ml within 24 hours of incubation while the values became ? 64 Mg/ml after 48 hours of incubation.There was a significant differences (p< 0.05) among tested treatments isolates incubated at 24 hours while there was no significant differences (P>0.05) at 48 hours of incubation. In respect with Ketoconazole, the resistance of C.albicans was increased after 48 hours of incubation at MICs values 0.125, 0.25, 0.5 and 1 Mg /ml while its was sensitive at values 4, 8 and 16 Mg /ml and the trailing growth phenomena occurred when the MICs ? 2 Mg/ml after 24 hrs of incubation, while it reached to ? 8 Mg/ml after 48 hrs of incubation. There was a significant differences (p< 0.05) among tested treatments incubated after 24 hours while there was no significant differences (P >0.05) among treatments after incubation 48 hours. The results of relative quantitative gene expression for both genes revealed a significant differences (p< 0.05) in gene expression levels through the occurrence of increased in the transcription of mRNA quantity among tested treatments.The up - regulation of Erg11 and fold change in mRNA transcription was 2.498 fold compared with 1.0 for control treatment after 24 hrs of incubation in the presence of antifungal, while the increasment was 12.606 fold after 48 hrs of incubation of isolates with antifungals.

المستخلص: Cryptic bacterial infection has been studied in urinary system to Human, where 50 underwent urine samples from patient mostly based consulting auditors Hilla public Education Hospital for the period from November 2012 until Feb. 2013. Patients ranged in age from 20 - 50 years males and females bacterial infection rate was 70% distributed between the cell wall defective bacteria had 38% and 32% cell - wall bacteria and the results showed 30% as negative cases. Amicroscopic examination of the urine sludge Showed clear sovereignty of non - specialized immune response type of mixed cell 34% followed by mononuclear cell 30%. Samples were cultured on routine media (Blood agar , Macchonky agar) and Modified media (Variant agar, Variant broth). Out put diagnosed by bacterial system diagnostics, phen - otypic, microscopically and biochemistry by using the special test for microorganism diagnosis and using API 20 E and the use VITEK 2 to confirm some samples results. Characterized by colonies of cell wall defective bacteria grow on variant agar it resembles fried egg which could seen after staining Deinse stain. Citrobacter freundii recorded 12%, the highest rate among cellwall defective isolates. Sensitivity test for bacterial isolates were screened from U.T.I both two type (CWB & CWDB) showed the highest rate of sensitive to Impinem 100% represented CWDB, as well as the highest rate of resistance to Ampicillin 100% represented by the same group of isolates. experimental study with urinary tract infection by injecting bacterial stuck of Citrobacter freundii to the three groups of rabbits : first group ( 3 Rabbits ) : immunized with viable surface antigen extracted from CWDB, second group : ( 3 Rabbits ) immunized with heat killed surface antigen extracted from CWB, the third group (4 Rabbits) represented control group it been treated with sterile normal saline. the injection process through urethra, and then underwent a histological study, was histological damage to the members of the animal - derived non - immunized (control group) seemed clear was the appearance of symptoms of the total cellular infiltration and disruption of the mucous layer and epithelial and other symptoms. The immunized animals have shown their ability to defy injury. It is the study of serological reactions to bacterial antigens Citrobacter freundii immunized with vaccines for rabbits given high caliber agglutination with its specialized vaccines and low with adversity and that the absorption and the corresponding and variant antigen does not remove the agglutination effectiveness with immune sera prepared suggesting that the absorption is incomplete and that the difference between the wall and a wall defective in terms of antigenic is quantitative and qualitative.
