A serological study using 3AB nonstructural protein ELISA and liquid phase blocking ELISA to assess foot-and-mouth disease virus (FMDV) non-structural and structural protein antibodies (NSP- and SP-Abs) was performed through sampling from 103 cattle and 37 buffalo bulls of an elite herd of north India. A total of 53 (51.46%) cattle bulls and 14 (37.84%) buffalo bulls were found positive for NSP-Ab indicating an exposure to FMDV. The proportion of animals showing ≥1.8 log10titre against all three serotypes in the vaccine varied from 58.25% for cattle bulls and 48.64% for buffalo bulls indicating poor vaccinal herd immunity, which assumably might have made the animals susceptible to virus exposure in the farm.
