摘要
牛星状病毒(Bovine Astrovirus,BoAstV)是一种无囊膜的单股正链RNA病毒.1978年,BoAstV首次在英国的犊牛腹泻粪便样本中被发现,此后在许多其他国家都有报道.它具有广泛的组织嗜性,在肠道、呼吸道和神经系统均可检测到病毒.由于BoAstV在无症状牛和临床感染牛中普遍存在,且通常与其他病毒存在共感染模式,因此BoAstV的致病性尚不清楚.目前越来越多的流行病学研究表明,BoAstV与犊牛腹泻、脑炎的症状相关,国内对BoAstV的关注日益增加.本文对BoAstV的病原学、流行病学、致病性、共感染、诊断方法和综合防控措施进行综述,为BoAstV的研究及综合防控提供参考.
Abstract
Bovine Astrovirus(BoAstV)is a single stranded RNA virus without a capsule.In 1978,BoAstV was first discovered in fecal samples of calves with diarrhea in the UK,and has since been reported in many other countries.It has a wide range of tissue preferences and can be detected in the intestines,respiratory tract,and nervous system.Due to the widespread presence of BoAstV in asymptomatic cattle and clinically infected cattle,and its co infection pattern with other viruses,the pathogenicity of BoAstV is still unclear.Currently,an increasing number of epidemiological studies indicate that BoAstV is associated with symptoms of calf diarrhea and encephalitis,and there is increasing attention to BoAstV in China.This article provides a review of the etiology,epidemiology,pathogenicity,co infection,diagnostic methods,and comprehensive prevention and control measures of BoAstV,providing reference for the research and comprehensive prevention and control of BoAstV.
