To investigate the seroprevalence of Streptococcus suis (S. suis) in pigs, a total of 875 sera samples (430 from organized farms and 445 from slaughterhouses), were collected and analyzed by enzyme linked immunosorbent assay (ELISA) for the detection of Streptococcus antibodies. The seroprevalence was found to be 52.8%. The rate of seropositivity was higher in slaughtered pigs (58.87%) as compared to live pigs from organized farms (46.51%). Growers showed higher seroprevalence as compared to other age groups. Females showed higher seroprevalence in slaughtered pigs while males showed higher prevalence in live pigs from organized farms. These findings suggested a high seroprevalence of S. suis in Indian pigs triggering a public concern. To the best of our knowledge, this is the first report of seroprevalence of S. suis infection in Indian pigs.
