Primary diagnosis and therapy tests of nephropathogenic avian infectious bronchitis
摘要
Abstract
[Objective ]The present study was conducted to investigate the epidemiology of avian infectious bronchitis (IB) in Qinhuangdao city of Hebei province, and to isolate the local representative strain of IB virus for development of immuo-vaccine. [Method]The epidemiology investigation, clinical manifestations and pathological changes in IB were recorded. The liver and kidney suspension of freshly sampled chicken were inoculated to ten--day SPF chick embryo allantoic cavity and the chicken embryo allantois solution was collected to conduct agar diffuse, haemagglutination (HA) and animal test. The comprehensive therapy was also practiced. [ Result ]The kidney of inoculated chick showed swelling and was found pale colored. White urate deposition in ureter was observed. The agar diffuse test result of allantois liquid showed positive results, as well as the HA and animal test results revealed that the isolated strain was IB virus. Based on pathological diagnosis, the lB was identified as nephropathgenic lB. The inactivated vaccine was made with isolated strains of nephropathogenic infectious bronchitis viruses. After 5 days of treatment with Hukang, Shenzhishuang, Hushentong and other medicines, the mortality of diseased chicken was recorded from 0.4 to 1.0％, the symptom in respiratory tract of chicken population decreased and the eggs production increased. The curative rate of lB in chicken reached 92.4％. [Conclustion ]The results of present study confirmed the disease as nephropathgenic lB. The proper medication and and immunization according to the virus strain can prevent the disease.关键词
