Serological evidence of bovine herpesvirus-1 (BoHV-1) infection in yaks (Peophagus grunniens) from the National Research Centre on Yak, India.

Bovine herpesvirus-1 (BoHV-1) causes a variety of disease syndromes including, respiratory, nervous and reproductive disorders both in domestic as well as wild bovines and the disease is prevalent throughout the world including India. In this study, serum samples of yaks were screened for serological evidence of BoHV-1 in a yak farm with history of abortion and kerato-conjuctivitis by competition-ELISA. The result of seroprevalence of BoHV-1 infections in yaks (Poephagus grunniens) revealed that the overall seroprevalence was 60.1%. The sero-prevalence of BoHV-1 infections was highest in male calf (67.7%) followed by yak cows (62.6%), yak bulls (56.8%), and yak heifers (50.0%).
