Abstract

(BoAHV-1) infection is common in cattle worldwide. However, information on the spread of BoAHV-1-circulating strains in Italy remains limited. In this study, we investigated an outbreak characterized by severe respiratory symptoms in a cattle herd ( = 30) located in Central Italy. BoAHV-1 was isolated from three cattle in a cell culture, which confirmed viral infection. Next, we characterized one (16453/07 TN) of the three isolates of BoAHV-1 using whole-genome sequencing. BLASTn and phylogenetic analysis revealed a nucleotide identity >99% with all BoAHV-1 strains belonging to subtype 1.1, highlighting the genetic stability of the virus. This study reports the first full genomic characterization of a BoAHV-1 isolate in Italy, enriching our understanding of the genetic characteristics of the circulating BoAHV-1 strain in Italy.

摘要

牛α疱疹病毒1型（BoAHV - 1）感染在全球范围内的牛群中很常见。然而，关于BoAHV - 1流行毒株在意大利传播的信息仍然有限。在本研究中，我们调查了意大利中部一个牛群（n = 30）中以严重呼吸道症状为特征的一次疫情。在细胞培养中从三头牛分离出BoAHV - 1，这证实了病毒感染。接下来，我们使用全基因组测序对BoAHV - 1的三个分离株之一（16453/07 TN）进行了特征分析。BLASTn和系统发育分析显示，与所有属于1.1亚型的BoAHV - 1毒株的核苷酸同一性>99%，突出了该病毒的遗传稳定性。本研究报告了意大利BoAHV - 1分离株的首次全基因组特征分析，丰富了我们对意大利流行的BoAHV - 1毒株遗传特征的理解。
