In this study, we investigated a goat pox outbreak that occurred in an organized goat farm in a village named Yerenda near Akola, Maharashtra, India during 2007-2008. The outbreak involved in 175 goats including kids of local nondescript breeds with a morbidity, mortality, and case fatality rate, respectively, of 20%, 11.4%, and 60%. The goat pox virus (GTPV) antigen/nucleic acid in the clinical samples was detected by CIE and PCRs whereas virus-specific antibody was detected by using SNT and indirect ELISA. From classical clinical signs coupled with epidemiological details and various diagnostic assays, the causative agent of the outbreaks, GTPV was identified, successfully isolated in Vero cells and characterized. Further, sequence analysis of P32 envelope protein gene revealed that this isolate phylogenetically related closely to Chinese strain.
在本研究中,我们调查了2007 - 2008年期间发生在印度马哈拉施特拉邦阿科拉附近一个名为耶伦达的村庄的一家规模化山羊养殖场的山羊痘疫情。此次疫情涉及175只山羊,包括当地土种山羊的幼崽,发病率、死亡率和病死率分别为20%、11.4%和60%。通过免疫扩散试验(CIE)和聚合酶链反应(PCR)检测临床样本中的山羊痘病毒(GTPV)抗原/核酸,同时使用血清中和试验(SNT)和间接酶联免疫吸附测定(ELISA)检测病毒特异性抗体。根据典型的临床症状、流行病学细节以及各种诊断检测,确定此次疫情的病原体为GTPV,并成功在非洲绿猴肾(Vero)细胞中分离和鉴定。此外,P32包膜蛋白基因的序列分析表明,该分离株在系统发育上与中国毒株密切相关。
