المستخلص: الايشريشيات القولونية مسئولة عن احداث حالات مرضية مختلفة تسبب خسائر اقتصادية ناتجة عن الهلاكات العالية وانخفاض معدل التحويل الغذائي والخسائر في اتلاف الجثث والاعضاء المصابة بعد الذبح.تم في الدراسة الحالية فحص 70عينة من افراخ فروج اللحم الهالكة او التي كا | Escherichia coli (E. coli) is responsible for a variety of diseases conditions which cause high economic losses in poultry due to high mortalities, decreased food conservation rate and condemnation of whole affected carcass or organs after slaughter. In the present study, 50 out of 70 broiler chickens which have been collected from diseased chickens were exhibited lesions of fibrinous perihepatitis, fibrinous pericarditis and/or airsacculitis. Birds with these lesions were subjected for bacteriological examination. The examination revealed isolation of 23 E. coli isolates with incidence of 46%. Concerning the virulence factors , Congo red binding activity of these isolates reveled detection of 6 positive isolates with incidence of 26.08%. Serotyping showed that out of 6 Congo red positive strains, only 3 strains were serologically typed and were belonged to the serotype O78 : K80. Detection of pathogenic E. coli serotypes was confirmed by PCR technique with specific primers for fimA and fimH genes. All these 3 isolates of the serotype O78 : K80 were reacted with these 2 genes. Antimicrobial suscebtibility pattern displayed sensitivity of these isolates to Chloramphinicol and Gentamicin and their resistance to Amoxicillin, Erythromycin and Nalidixic acid. Experimental infection has been made with this isolate. Two groups of broiler chickens were used the first at one day old and the second at 5 weeks of age. Signs, lesions, histopathological changes were revealed that the first experiment was differed from the second through the presence of pus in the bursa of Fabricius, but hemorrhage in the lungs tissue occur in two experiments.

المستخلص: تعتبر الكوكسيديا في الدواجن واحدة من الامراض الرئيسية التي تؤثر على اداء الدواجن المرباة تحت نظام الانتاج المكثف الذي يؤثر على صناعة الدواجن في جميع انحاء العالم، بخسائر اقتصادية كبيرة عن طريق قلة التحويل الغذائي وخفض الانتاجية. هذا ليس فقط يعيق نمو الدجا | Coccidiosis in poultry is still considered as one of the main diseases affecting performance of poultry reared under intensive production system that affects the poultry industry worldwide , having major economic losses in poultry by reducing performance and decreasing productivity.this disease not only hinders the growth of chickens but also facilitates other epidemic diseases. Coccidiosis is mainly controld by prophylactic coccidioststs administrated in the feed. However , the extensive use of these drugs has resulted in the development of drug resistance by Eimeria spp., Which causes Coccidiosis.The aim of the study was to updated the recent information of of infection,gross evaluation of the intestinal tract and microscopic evaluation of wet smear are used as routine diagnostic methods and to acquire data on the prevalence of coccidiosis and drug resistance of field isolated in chickens,Frequent use of anticoccidial drugs ,however , has resulted in the development of resistance in the Eimerian spp. Because farmers mainly rely on the prophylactic and therapeutic use of chemicals for the control of avian coccidiosis. Increasing awareness about populic health hazards associated with drug residues in food chain has also added to the constraints in using synthetic drugs for treatment and control of disease in animals and control methods according to the collected formation chickens were in danger of clinical coccidiosis , and here coccidia generated a certine degree of resistance and not easy ty control in our industry in Iraq because of that the poultry industry in Iraq is not as integrated system without strict biosecurity. The study also highlight the information on the anticoccidial vaccines are in the market with controversial efficacy.

المستخلص: اجريت هذه الدراسة لتقييم مدى انتشار مرض التهاب القصبات المعدي الفيروسي في دجاج اللحم في محافظة ذي قار, قسمت منطقة الدراسة جغرافيا الى خمسة مناطق (شمالية, جنوبية, غربية , شرقية, مركزية) حيث تمت الدراسة على عشرون حقل دجاج لحم غير ملقحة اربعة قاعات من كل منط | The current study was conducted for evaluation of prevalence of IB in broilers in the Thi - Qar province, which geographically divided into five regions, (Northern, Southern, Western, Eastern and central area), twenty broiler farms without history of previous vaccination, four from each region were included in this study. Serum and autopsies were collected from affected birds after recording of the clinical signs that observed on the birds; positive serum samples that detected by rapid test were used for evaluation the antibodies titrations by ELISA technique, while the histological specimens (trachea, lung and kidney) were used for detection of histopathological changes and detection of presence of the IBV infection by molecular approach (real time - PCR). The clinical manifestation includes : typical respiratory sings of IB infections, with depression, rough feather, and assembling near the heat source, as well as some birds were found dead with mortality rate ranging between 30 - 80%. Also 96 serum samples were collected from other broiler farms as following ( 42 asymptomatic vaccinated, 54 asymptomatic non - vaccinated, 26 symptomatic vaccinated) for ELISA and real time PCR tests. The result of rapid test showed that the percentages were different among the areas of study when the southern area revealed the highest percentage (80%) among the others followed by the northern area and western (70%), then central and eastern(65%). The results of ELISA showed a high titer for antibody of IBV in all these farms in areas of the study, but the highly significant results (P<0.05) were found in the southern area(7032.2±1640.92) and then northern area (5722.18±2060.1), a less significant differences were in central and eastern areas (3188.11±742.45; 3161.8±52.6) respectively. In relation to age, the high titer of IB antibodies in total 20 farm by ELISA were recorded in 12 farms at 4 weeks of age (60%) followed by 4 farms at 5 weeks of age (20%), 3 farms at 3 weeks of age (15%) and 1 farm at 2 weeks of age (5%), while there is no recorded infection in farms at 6 ages. According to history of vaccination and clinical manifestation of tested birds, most of the tested flocks showed high level of antibody titers to IBV by ELISA technique in asymptomatic vaccinated chickens samples 38/42 (90%) followed by asymptomatic non vaccinated chickens 8 (14.8%) and symptomatic vaccinated chickens 6(23.07%). While rRT - PCR showed that 69 ( 80%) sample were revealed positive results. The most important gross lesion observed on immediately the necropsy after death were tracheal congestion, caseous exudates in the trachea, pneumonia, airsacculitis, pericarditis and perihepatitis, as well as, nephritis; while The histopathological changes were summarized by desquamation of tracheal epithelial cells and hemorrhage with infiltration of inflammatory cells specially lymphocyte cells, hyperplasia of epithelial cells with hemorrhage, lung sections showed severe infiltration of inflammatory cells mostly lymphocyte cells and severe congestion with spots of pneumonia and the histopathological changes in kidneys were characterized by tubules degeneration , glomerular distention with severe hemorrhage and lymphocyte infiltration.

المستخلص: تعد انفلونزا الطيور والتهاب القصبات المعدي والنيوكاسل من الامراض المهمة اقتصاديا في صناعة الدواجن.صممت الدراسة الحالية لتسليط الضوء على دور فيروسات ND, IB, AI , ومعرفة مدى انتشارها في احداث الاوبئة التنفسية في دجاج اللحم باستخدام تقنية الاستنساخ المن | Avian influenza, Newcastle disease and Infectious bronchitis are diseases that have economical importance in poultry industry. This study was designed to clarify the roles of IBV, AIV and NDV in an outbreaks of respiratory diseases in broiler chickens by using ELISA and real time RT - PCR assay in Al - Diwaniyia province , Iraq. A total of 30 commercial broiler flocks with high mortality (20 to 80 %) in Al - Diwaniyia province were investigated.Tracheal swabs and tissue specimens ( Trachea, lung, kidney and cecal tonsils ) were tested initially by rapid test for detection of Infectious bronchitis virus ( IBV ) , Influenza type A virus ( AIV) and Newcastle disease virus (NDV).The total results of rapid immunochromatography assay showed that out of 30 flocks 28 ( 93.33%) were positive for IBV and 21(70%) flocks were positive for AIV while 4(13.33%) flocks were positive for NDV. Blood samples were collected for detection of antibodies against IBV, AIV & NDV in serum samples , the results of indirect ELISA showed that out of 30 flocks were 30(100%) gave positive result with indirect ELISA test for IBV and 23(76.67%) flocks were positive for AIV (H9 ) whereas 5(16.67%) flocks showed positive result for NDV. The result of rRT - PCR showed out of 30 (100%) flocks were positive for IBV and 23(76.67%) positive for AIV (H9) whereas 5(16.67%) flocks were gave positive results for NDV. In conclusion the high positivity in the examined broiler flocks were mainly due to mixed infections of IBV, AIV(H9) and NDV, However we concluded that IBV and AIV were most important causes of respiratory diseases in this study. Also this study demonstrated that Real time qRT - PCR technique and ELISA were rapid and accurate as diagnostic tool in early detection of IBV, AIV and NDV.
