Countrywide cross-sectional study of swine brucellosis sero-prevalence in Indian subcontinent during 2018–2019

Brucellosis in swine is a contagious disease with greater zoonotic potential caused by Brucella suis. The study describes PAN India swine brucellosis sero-prevalence in 5431 stratified random serum samples collected during 2018–2019 from 26 out of 29 states and two out of seven union territories. The serum samples were tested for anti- Brucella antibodies by indirect ELISA and overall, 4.33% apparent prevalence (AP) was recorded. The AP is ≥ 10% in five states among 26 states, P ≥ 50% in four districts out of 117 districts screened and cent percent prevalence in two epi units out of 264 sampled. Significantly high seropositivity ( p
