The presence of antibodies to bluetongue virus (BTV) and the viral antigen is reported recently from the Andaman and Nicobar Islands, a group of islands at the juncture of the Bay of Bengal and the Andaman Sea. A retrospective study was conducted to investigate the presence of neutralizing antibodies to different BTV serotypes in the seroconverted goats of the Islands. Thirty six samples out of 186 serum samples tested were selected on the basis of high antibody titre as predicted in an indirect ELISA. Each of the selected serum samples was used for neutralization of six BTV serotypes (BTV-1, BTV-2, BTV-9, BTV-10, BTV-16 and BTV-23), the most commonly reported serotypes in India. Out of 36 serum samples used in the neutralization study, neutralizing antibodies could be determined in 15 samples. The neutralizing antibodies to BTV-10 were found in more number of the serum samples followed by BTV-1, BTV-2 and BTV-23 and BTV-9 and BTV-16. Many of the serum samples could neutralize more than one BTV serotypes indicating possible widespread superinfections by multiple BTV serotypes in goats in the Islands. Majority of the serum samples used in the neutralization study could not neutralize any of the six BTV serotypes commonly reported from India indicating possible circulation of other BTV serotypes yet to confirm. The present study reveals circulation of multiple BTV serotypes in Andaman and Nicobar Islands where there was no such report available earlier. The findings are laudable as the baseline information for further investigations to identify and characterize the virus and competent vectors and for implementing appropriate suitable control strategies for bluetongue in the Islands and the nearby territories.
