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: 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

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.

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).

المستخلص: اجريت هذه الدراسة التي امتدت من بداية شهر ايار (2007) لغاية نهاية شهر اب (2008) للتحري عن نسبة الخمج بالطفيلي المسبب لداء المقوسات بين النساء المجهضات والولودات طبيعا في بعض مناطق مدينة الموصل والمراجعات لمستشفى الخنساء التعليمي للولادة والاطفال.شملت عي | This study was conducted during the period from May 2007 to August 2008 to investigate the rate of infection with toxoplasmosis among aborted and normally delivered women in Mosul City territories who attending AL - Khansa'a educating hospital.Out of 150 women under study, 50 were aborted while 100 were normally delivered. The employed tests were included latex agglutination test LATEX and Enzyme Linked Immunosorbent Assay (ELISA) with its two types (ELISA - IgM), (ELISA - IgG) which used as a high specific and sensitive test to differentiate between types of infection acute, chronic and congenital. Toxoplasmosis was diagnosed in 28(56%) out of 50 abortive placenta and in 57(57%) out of 100 non abortive placenta (normally delivered women), these samples of placenta were microscopically examined after homogenizing and staining by Gimsa and Leishman's stain The parasite development stages were also noticed including developing from the tachyzoites into the oocysts stage and the histopathological effects resulting from infection in the placenta in both aborted and normally delivered women which were represented by necrosis, vaculation and cells degeneration , inflammatory cells infiltration and the focal inflammatory reaction in the villi in addition to hemorrhage and accumulation of eosinophilic substances, the results also showed that 41 (82%) of aborted placenta and 18 (18%) of non abortive placenta (normal delivered women) were infected with Toxoplasmosis by using the laboratory Balb/c mice inoculation method while, some cases of inflammation were diagnosed in the brain, of the experimental infected mice, which were represented by the inflammatory cells infiltration and the prevailing of gliosis, tissue necrosis vaculation and cells degeneration.This study revealed that laboratory mice inoculation in the peritoneal cavity is a useful and efficient method in the detection of the parasite in infected placenta as compared with the microscopic examination of direct smears and examination of tissue sections from placenta.The present study showed an overall percentage of infection among aborted women was (92%) while (58%) showed an acute infection and (34%) chronic infection, in another hand the infection rate among normally delivered women was (70%), and it has been found the infection rate among acute and chronic cases were (41%), (20%) respectively, Its to be noted this is the first time in Mosul City for such a study conducted in this area concerning the congenital Toxoplasmosis in newborns with an infection rate (9%).In this study, sera were tested by Latex (LAT), and Enzyme Linked Immunosorbent Assay (ELISA). It was shown that IgG - ELISA is the most sensitive to diagnose the infection as compared to other tests.These study also concerned with the isolation and diagnosis of Toxoplasma gondii parasite from blood by inoculating the blood samples in laboratory Balb/C mice the rate of infection was (16%) in laboratory mice inoculated with blood collected from aborted women while the infection rate in laboratory mice inoculated by blood samples (mother and her neonatal cord blood) collected from normally delivered women appear in (12%) & (16%) respectively. The rate of occurrence of the specific antibodies against Toxoplasma gondii was identified, The highest rate was found for the type (IgG+ - IgM+), in both aborted and normally delivered women with percentage reach (40%) & (26%). The titer (100 IU/ml) of the specific IgM & IgG antibodies was found in high rate reached (75%), (43.5%) in mother blood, also found in a high percentage in the neonatal cord blood estimated as (50%), (64.4%) for the specific IgM & IgG antibodies respectively, in another hand the titer (100 IU/ml) was also found to be the more predominate titer in blood samples of aborted women with percentage reached to (50%) & (60.5%) for the specific IgM & IgG antibodies respectively.
