ABSTRACT
Vaccination of the foot and mouth disease (FMD) virus needs the examination of the prevalent virus serotypes in the area. The current cross-sectional study was conducted in the Bahawalpur district of Punjab, Pakistan, with the purpose to determine the prevalence of FMD virus serotypes Asia 1, O and A in bovines. A total of 838 bovine sera samples were tested through Solid phase competitive enzyme-linked immunosorbent assay (SPC-ELISA), based on structural proteins at the National Veterinary Laboratory (NVL), Islamabad from 10 January 2021 to 09 January 2022. The overall bovine population was carrying maximum seroprevalence of serotype O (28.52%) followed by serotype Asia 1 (23.63%) and serotype A (13.6%) in district Bahawalpur. Majority of the bovine population (50.26%) was detected seropositive for type O of foot and mouth disease virus (FMDv) followed by serotype Asia 1 with (37.17%) in tehsil Ahmedpur East and type A with 21.83% prevalence in tehsil Bahawalpur. Moreover, it was emphasized that seropositive cases of type O (42.88%), Asia 1(36.69%) and type A (21.33%) were significantly higher in vaccinated bovine group as compared to non-vaccinated bovine with (12.93%), (9.45%) and (5.22%) respectively across the district. More specifically the cow population was carrying maximum seroprevalence of type O with (60.55%) compared to buffalo with (36.58%). It was concluded that serotype O was more prevalent in district Bahawalpur followed by serotype Asia 1 and serotype A and cow population was found more susceptible than buffalo.
