In view of the absence of comprehensive information on the BT status in India, this study presents the seroprevalence data on BT in farm animals of India based-on a systematic review and meta-analysis. A systematic review was conducted to identify the published articles (2001-2018) reporting the seroprevalence of BT in sheep, goats, cattle, buffalo, camels, and Mithun (Bos frontalis) from India. From 409 research articles, 71 fulfilled the inclusion criteria and meta-analysis for proportions was carried out targeting the eligible studies. From these, 144 strata level data were extracted with a sample size of 14048 sheep, 14696 goats, 5218 cattle, 2653 buffaloes, 2062 camels, and 222 Mithun. Overall, the analyses showed that the BT seroprevalence of 43% (95% CI: 38-49%) in goats, 39% (95% CI: 33-46%) in sheep, 38% (95% CI: 25-45%) in cattle, 34% (95% CI: 20-51%) in buffaloes, 16% (95% CI: 10-22%) in camels, and 66% (95% CI: 17-95%) in Mithun. Furthermore, the meta-regression analysis suggested that serological tests, geographical re...
