Abstract

There is dearth of availability of surveillance reports elucidating the role of mithun, yak and their hybrid populations inhabiting north-eastern regions of India in the epidemiology of foot-and-mouth disease (FMD). This study conducted during 2015–2016, therefore highlights the serological status of the disease in these animals of Arunachal Pradesh. A total of 857 sera from 804 yaks, 44 mithuns and 9 hybrids of mithun and yak were collected and an indirect 3AB nonstructural protein (NSP) ELISA was performed to detect NSP-antibodies (NSP-Abs). A prevalence of FMD virus (FMDV) NSP reactive sera in 25.12% (202/804) yak and 2.27% (1/44) mithun was estimated, while 0% seroreactivity was observed in their hybrids. The findings inferred that FMDV circulates in the said animals populating Arunachal Pradesh. Hence, necessary control measures including prophylactic vaccination for FMD should be put into practice to safeguard these rare threatened species considered to be the pride of the country.
