Seroprevalence of Rotavirus infection in pig population of Arunachal Pradesh

AIM: This study was conducted to find out the seroprevalence of Rotavirus(RV) infection among the pig population of Arunachal Pradesh. MATERIALS AND METHODS: Serums samples were collected from piglets of age ranging from 1 week to 6 months and the sows associated with the piglets that were reared under organized and unorganized system of management in six different districts of Arunachal Pradesh. The prevalence of RV specific antibodies was detected using a polyclonal antibody-based indirect enzyme-linked immunosorbent assay (i-ELISA). RESULTS: The study revealed that out of 394 serum samples, 255 (64.72%) samples were found to be positive for RV-specific antibody in i-ELISA. Considering the samples from different districts, Papumpare district of Arunachal Pradesh showed highest numbers of seropositive animals (68.75%) followed by upper Subansiri (64.91%) while West Siang district showed lowest positivity rate (61.22%). CONCLUSION: As considerable seropositivity was recorded among pig population of Arunachal Pradesh in this study, there is urgent need to establish high-impact and cost-effective public health intervention tools, key among them being the introduction of strict hygiene practice and RV vaccination program, to greatly reduce the number of deaths due to diarrheal diseases. To the authors’ knowledge, this is the first report on the prevalence of RV infection from pigs of Arunachal Pradesh.
