| 摘 要： | 从蛋鸡临床表现为产蛋下降、卵泡萎缩、卵泡膜出血为主要特征的发病蛋鸡的卵巢、输卵管、肝、脾等组织中分离到3株病毒.分离毒能致死番鸭胚和鸡胚,人工感染产蛋期的蛋鸡能导致蛋鸡产蛋急速下降,卵泡出血和萎缩,并能从人工感染病鸡中回收到病毒;分离毒不能凝集鸡和鸽红细胞,并对乙醚、氯仿敏感;病毒核酸为RNA;PCR或IFA结果排除了...

| Abstract: | Three virus strains were isolated from the diseased layers that experienced abrupt reduction in egg-laying in different regions.These isolated viruses could cause SPF chick-embryo and Muscovy duck-embryo to die with hemorrhage in embryo-livers.Healthy egg-producing layers inoculated with these isolates showed symptoms similar to that of the field cases,and the same viruses could be reisolated.These isolates could proliferate in MDEF causing cytopathic effect.They showed no haemagglutination activity,were se... |
