An outbreak of Goatpox virus infection in Wild Red Serow (Capricornis rubidus) in Mizoram, India

摘要

Goatpox virus (GTPV) belongs to the genus Capripoxvirus associated with characteristic clinical lesions in fully susceptible breeds of sheep and goats. To date, there is no report of outbreaks of GTPV infection in any wild animals. This study reports the outbreak of GTPV infection in wild Red Serow (Capricornis rubidus.) in Mizoram, India. A total of 113 wild Serow carcasses were recovered from seven districts of Mizoram between May 2015 to October 2016. A postmortem revealed presumptive pox-like lesions. Clinical specimens (lung, skin, and trachea) were examined for the aetiological agents. GTPV could be isolated in PLT cells and confirmed in PCR assays by targeting RPO30 and P32 genes. The genetic and phylogenetic analysis reveled that over 99.8% sequence identity with GTPV from India and other parts of the world. To the authors' knowledge, this is the first report of GTPV infection in wild ruminants.
