中文摘要 | 為探究10株台灣分離雞傳染性支氣管炎病毒(infectious bronchitis virus, IBV)之病原性,將各株IBV分別接種1日齡SPF (specific-pathogen-free)雞,然後登記其臨床症狀指數、發病率、死亡率,氣管和腎臟剖檢病變值,供進行病原性分型之參考依據。並將各株IBV分別接種至具母源抗體的1日齡肉雞測試母源抗體保護效力。結果10株IBV分離株可區分為強毒型2株、中間毒型4株及弱毒型4株。不同毒力的IBV攻毒時,腎臟病變與死亡發生有極顯著相關(P<0.01)。而母源抗體的存在可使肉雞臨床症狀、死亡率及腎臟病變的發生率顯著降低(P<0.05)。 |
英文摘要 | In order to investigate the pathogenicity of ten infectious bronchitis virus (IBV) strains isolated in Taiwan, they were inoculated into one-day-old specific-pathogen-free chicks. The pathogenicity of 10 IBV strains were evaluated according to the mortality and the tracheal and renal lesions. The challenge test was conducted in day-old broilers with maternal antibody to evaluate the protection efficacy of maternal antibody against field IBV challenge. According to the pathogenicity test in SPF chicks, 10 IBV strains were grouped into 2 high, 4 intermediate, and 4 low pathogenicity. The renal lesion was strongly correlated to mortality after IBV challenge (P<0.01). The protection of maternal antibody reduced the mortality, renal lesions and the clinical sings (P<0.05). |
