Abstract

Aim: This study aimed to evaluate the prevalence of antibodies against two economically significant viral pathogens in domestic pigs like porcine reproductive and respiratory syndrome virus (PRRSV) and classical swine fever virus (CSFV) through a serological study in swine herds in Mizoram, India.

Methodology: Serum samples were collected from apparently healthy and suspected pigs of different age groups comprising weaners, growers and adult in four districts (Aizawl, Champhai, Kolasib and Serchhip) of Mizoram during February, 2018 to June, 2019. Seroprevalence of CSFV and PRRSV specific antibodies was detected by enzyme-linked immunosorbent assay (ELISA).????

Results: Out of 420 samples, 117 samples were found positive for PRRSV, 171 samples for CSFV indicating a mean positivity of 27.86% and 40.48%. Presence of mixed infection was observed in 13.33% samples.??????

Interpretation: The present study demonstrated the extensive circulation of classical swine fever virus and porcine reproductive and respiratory syndrome virus among domestic pig populations of Mizoram, India.?
