Abstract: جمعت (140) عينة من المرضى الراقدين لثلاثة ايام فاكثر في مستشفى تكريت التعليمي للمدة من 1 - 8 - 2009 ولغاية 1 - 12 - 2009 بهدف تحديد العزلات الجرثومية الاكثر شيوعا ضمن اخماج مستشفى تكريت التعليمي ومقاومة هذه العزلات للمضادات الحيوية ودراسة العلاقة بين مقاو | One hundred fourti samples were collected from hospitalized patients for three days or more in the Tikrit Teaching Hospital during the period from 1/8/2009 until 1/12/2009 to determine the most commonly isolated bacterial from nosocomial infections in Tikrit Teaching Hospital and their resistance to antibiotics and to study the relationship between antibiotics resistance and plasmid content in the most commonly isolated bacteria and to evaluate the prevalence of these plasmids in the hospital environment. 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.

Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.

Abstract: اجريت الدراسة في قسم علوم الحياة - كلية التربية - جامعة تكريت من شهر تشرين الثاني 2010 الى شهر تموز 2011 ? وكان هدف الدراسة هو معرفة بعض الصفات الفيزياوية والكيمياوية للمياه المطروحة من شركة مصافي الشمال/بيجي وامكانية استخدامها لري بعض المحاصيل الزراعية ب | This study was conducted at the Department of Biology in the College of Education - University of Tikrit. The study aims at estimating some physical and chemical characteristics of water raised from the North Refineries Company / Baiji and can be used to irrigate some crops after treatment with a number of physical methods. It also aimed at estimating some heavy elements and their impact on the growth of plants that have been studied (tomato, eggplant, sweet pepper, hot pepper). The region from which samples have been brought of the area was Albu Juwaree village that is located in the city of Baiji and adjacent to the company. Besides, it occurs near wide agricultural areas. After estimating some physical and chemical characteristics of water, soil, and the proportion of oil waste, qualities of plants were studied as well as the assessment of (carbohydrates, proteins) and some of the heavy elements and their effects on the growth of those plants.The results showed that the water of industrial waste led to a reduction in the proportion and natural growth of plants. The most affected seeds were the seeds of sweet pepper, where the total percentage of germination was(0%) when infected %)100) and the least affected seeds were the seeds of tomato, where the total percentage of germination seeds was (80%) when water is contaminated (100%). The treatment by filtering has achieved the best germination of seeds of tomato and sweet pepper, where the ratio was (100%). It turned out that contaminated water has prevented the natural growth of those plants in respect to the number and the size of leaves, the length of roots and the weight of fresh and dry leaves. The methods of physical treatment showed that lightening (25%, 50%, 75%) made to the contaminated water led to the removal of the significant effects, especially when lightening was (75%).The results indicate that there is no significant differences in the lengths of the roots of tomatoes and eggplants, except for the root of hot and sweet pepper.While the heavy elements, which was part of the study in this research, beginning with cadmium was at its highest value at the treatment by filtering and less value in (100%). Through the study it was found that the percentage of lead in all studied plants were (0.00) ppm. The Results showed that the contaminated water led to the reduction of the proportion of carbohydrates with the increase of pollution(%100), where the least proportion of carbohydrates was at the treatment by filtering. The results also showed a decrease in protein concentration with the least proportion at lightening and less value in. (25%)The results showed that the water content of contaminated industrial heavy metals studied (cadmium - lead - copper - zinc - nickel) has decreased at all treatment when treated by filtering, as well as for the remaining elements, except lead, which was (0.00) in all plants and all lightening ratios.The results of this study show that treatment of contaminated water with industrial oil waste by physical methods led to minimizing the negative impacts of such water in reducing the percentage of germination and the reduction below the natural growth compared with non - treatment water and showed that the best way of treatment for the best growth of plants were lightening with (75%) and treatment by filtering. The best response to the treatment was tomato and the most resistant to pollution were (tomato and eggplant) and the most affected by contamination and least resistant was sweet pepper.

Abstract: تضمنت الدراسة عزل وتشخيص انواع تابعة للجنس Streptomyces، اذ جمعت 50 عينة من ترب اقضية تابعة لمحافظة صلاح الدين. شخصت?11 نوع من بكتريا Streptomyces باستخدام الاختبارات الشكلية والمزرعية والكيموحيوية حيث ظهر كل من الانواع (Streptomyces antibioticus, Strep | The Study involved ; isolation and characterization of species related to Streptomyces. Fifty samples of soil has been taken from different districts of Salah aldden province. The isolates were identified by the morphological, biochemical tests and classified to nine species, The following species were found : (Streptomyces antibioticus, Streptomyces coelicolor , Streptomyces distalicus and Streptomyces fluvissimus ) in Tikrit district, ( Streptomyces cyaneus ) in Ballad and beiji districs, ( Streptomyces exofolicus) in Ballad and Aldor districts (Streptomyces lavendulea ) in Samarra and Aldor districts , (Streptomyces purpureus ) in Samarra and Beiji districts and (Streptomyces violaceus ) in Samarra and Tikrit districts. The sensitivity of these bacterial isolates were tested toward the following : (Azithromycin, Cefotaxime, Cephatexin, Doxycycline, Erythromycin , Gentamicin, Neomycin, Penicillin, Tobramycin and Vancomycin).All species showed high resistance to cefotaxime. But all species were sensitive to neomycin and doxycycline. The isolated species of Streptomyces were tested for their ability of antibiotic production. It was found that (Klebsiella) was sensitive to all the species except species Streptomyces coelicolor. Streptomyces coelicolor showed an effect against Proteus. While Staphylococcus aureus was sensitive to the following species (Streptomyces antibioticus, Streptomyces cyaneus and Streptomyces purpureus). The Scanning Electron Microscopy was used to study the surface of spores. The species of (Streptomyces antibioticus) was found to has warty surface while spores of ( Streptomyces coelicolor) has smooth surface.

Abstract: 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).
