Abstract

Polymerase chain reaction (PCR) was used to test six different nonbovine ruminant species for five bovine herpesviruses including infectious bovine rhinotracheitis virus (BoHV-1), bovine herpes mammillitis virus (BoHV-2), Movar-type herpesvirus (BoHV-4), bovine herpesvirus type 5 (BoHV-5), and alcelaphine herpesvirus 1 (AlHV-1). Species tested included 56 roe deer (Capreolus capreolus), 66 red deer (Cervus elaphus), 20 fallow deer (Dama dama), 16 mouflon (Ovis musimon), 34 domestic sheep, and 44 domestic goats, which were sampled in Hungary in 2003. Tracheal and popliteal lymph nodes collected from these animals were tested for the presence of the five bovine herpesviruses using three nested (two of which were duplex) PCR assays. Three bovine herpesviruses (BoHV-1, -2, and -4) were detected, whereas no evidence of AlHV-1 or BoHV-5 was observed. Prevalence of BoHV-1 ranged from 12% to 47%, and PCR-positive results were observed in all species tested. BoHV-2 was detected from roe deer, red deer, fallow deer, mouflon, and domestic sheep, and the prevalence in these species ranged from 3% to 50%. BoHV-4 was detected in all species, with prevalence ranging from 12% to 69%. Sequenced PCR products were 99-100% identical to bovine herpesviral sequences deposited in the GenBank.

摘要

采用聚合酶链反应(PCR)对6种不同的非牛反刍动物进行检测,以筛查5种牛疱疹病毒,包括传染性牛鼻气管炎病毒(BoHV-1)、牛乳头炎疱疹病毒(BoHV-2)、莫瓦尔型疱疹病毒(BoHV-4)、牛疱疹病毒5型(BoHV-5)和牛羚疱疹病毒1型(AlHV-1)。检测的物种包括2003年在匈牙利采集样本的56只狍(Capreolus capreolus)、66只马鹿(Cervus elaphus)、20只黇鹿(Dama dama)、16只摩弗伦羊(Ovis musimon)、34只家养绵羊和44只家养山羊。利用三种巢式PCR检测方法(其中两种为双重PCR检测方法)对从这些动物采集的气管和腘淋巴结进行检测,以确定是否存在这5种牛疱疹病毒。检测到三种牛疱疹病毒(BoHV-1、-2和-4),未观察到AlHV-1或BoHV-5存在的证据。BoHV-1的感染率在12%至47%之间,所有检测物种均观察到PCR阳性结果。在狍、马鹿、黇鹿、摩弗伦羊和家养绵羊中检测到BoHV-2,这些物种的感染率在3%至50%之间。在所有物种中均检测到BoHV-4,感染率在12%至69%之间。PCR扩增产物测序结果与GenBank中存档的牛疱疹病毒序列的同源性为99%-100%。
