Bovine herpesvirus 4 (BoHV-4) is increasingly believed to be responsible for several disorders of the bovine reproductive tract. The first characterization of BoHV-4 in Argentina was from samples from an aborted fetus. Argentinean isolates are highly diverse and are phylogenetically grouped in three genotypes. In this study, we describe the isolation of BoHV-4 from a bovine fetus with a gestational age of 8 months and without macroscopic lesions. Genetic analyses revealed that the isolated strain belongs to genotype 2. This is the first report on the presence of infectious BoHV-4 in tissues from an aborted bovine fetus.

从阿根廷流产的胎儿中分离出的第一个牛伽马疱疹病毒4株的特征。

牛疱疹病毒4（BoHV-4）越来越被认为与牛生殖道的多种疾病有关。BoHV-4在阿根廷的第一个特征是来自流产胎儿的样品。阿根廷分离株高度多样化，并在系统发育上分为三种基因型。在这项研究中，我们描述了从胎龄为8个月且无肉眼可见病变的牛胎儿中分离BoHV-4的方法。遗传分析表明，分离出的菌株属于基因型2。这是关于流产的牛胎儿组织中感染性BoHV-4的首次报道。
