Abstract

A total of 29 faecal samples collected from dogs with diarrhoea following canine parvovirus (CPV) vaccination were tested by minor groove binder (MGB) probe assays for discrimination between CPV vaccine and field strains and by diagnostic tests for detection of other canine pathogens. Fifteen samples tested positive only for CPV field strains; however, both vaccine and field strains were detected in three samples. Eleven samples were found to contain only the vaccine strain, although eight of them tested positive for other pathogens of dogs. Only three samples were found to contain the vaccine strain without evidence of canine pathogens. The present study confirms that most cases of parvovirus-like disease occurring shortly after vaccination are related to infection with field strains of canine parvovirus type 2 (CPV-2) rather than to reversion to virulence of the modified live virus contained in the vaccine.

摘要

对29份从接种犬细小病毒(CPV)疫苗后出现腹泻的犬只采集的粪便样本,采用小沟结合剂(MGB)探针检测法鉴别CPV疫苗株和野毒株,并通过诊断检测法检测其他犬类病原体。15份样本仅检测出CPV野毒株呈阳性;然而,3份样本中同时检测出了疫苗株和野毒株。11份样本仅含有疫苗株,不过其中8份样本检测出感染了其他犬类病原体。仅3份样本含有疫苗株且未发现犬类病原体感染迹象。本研究证实,接种疫苗后不久发生的大多数细小病毒样疾病病例与感染2型犬细小病毒(CPV-2)野毒株有关,而非疫苗中所含的减毒活病毒返强所致。
