Abstract: 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.

Abstract: استخدم في الدراسة 200 فرخ لحم سلالة روز بعمر يوم واحد وغير مجنس لغرض استخدام فحصي الاليزا واثباط التلازن الدموي في تحديد معيار الاضداد في افراخ اللحم المحصنة بطرق مختلفة ضد مرض النيوكاسل واجريت الدراسة في فرع الامراض وامراض الدواجن / كلية الطب البيطري / | In this study 200 Ross breed broiler chicks aged 1 day and in both sex used for using of ELISA and HI tests in determination the titer of antibody in broiler chicks which vaccinated by different ways against Newcastle disease. the study done in a special house in college of Veterinary Medicine / Basra University / Department of Pathology and Poultry disease. The chicks divided randomly to 5 treated groups each one contain 35 chicks and the 6th group not treated (Act as control) contain 25 chicks. All chicks provide free feed and the 5 groups vaccinated by different ways against Newcastle disease , in 7th day vaccinated with Hitchner B1 vaccine and in days ( 21 and 35) with LaSota vaccine.The 1st and 2nd groups vaccinated by drinking water , in the 1st group used of tap water mixed with Skimmed milk while in the 2nd group used of RO Water. The third group vaccinated by spray , the 4th group vaccinated with eyes drop and the 5th group vaccinated in nostril. The distilled water used with vaccine of third , 4th and 5th groups , the control group leaved without vaccination. All groups vaccinated against Gumboro disease in 14th day of age. The blood sample collected in ages of ( 1 , 21 , 35 , 49 ) days with the range of 10 specimens from each group and 5 specimens from the control group then serum separated in order to testing immunity by using of Elisa and HI tests.Because of maternal immunity the titer of antibody in the 1st day was very high in range different in probability (0.05 >P) in comparison with other days (21 , 35 , 49 ) in other groups.The result of ELISA test show that the 1st group was excellence in (49) days of age that used the tap water mixed with skimmed milk in comparison with other groups in days ( 21, 35 ) with range different in probability of (0.05 >P). The 2nd group which was used of RO water the second order while the third group which used the spray vaccination was in third order and the 4th and 5th groups were some that the same in result and there was no any moral different.The result of HI test show that the 1st group that used of tap water mixed with skimmed milk was excellent in (49) days of age in comparison with other groups in days ( 21 , 35 ) with range moral different in probability of (0.05 >P). The 4th group that used of eye drop vaccination was in second order , the third group that used of spray vaccination in third order while the 2nd and 5th groups were somewhat similar in result and there was no moral different.We concluded that the vaccination by using of drinking water that consist of tap water mixed with Skimmed milk was the best methods and gave an important satisfactory results in comparison with other methods. The ELISA test have high efficiency and best than HI test in detection titers of Newcastle disease antibodies due to the test sensitivity in measurement of IgY present in vaccinated chicks serum while the HI test didn’t reach the same sensitivity of ELISA test in complete detection of this immuno globulin ( IgY ).
