The survey was to investigate the seroprevalence of T. gondii in Tibetan pigs in Tibet, China. A total 454 serum samples were collected from Tibetan pigs in Nyingchi in 2014 and 2015. Each sample was assayed for T. gondii antibodies by a commercial enzyme-linked immunosorbent assay kits and an indirect hemagglutination test. The results showed that seroprevalence in Tibetan pigs were 25.6% by ELISA. On gender basis, the prevalence was found 25.1% in males and 27.8% in females. By the method of IHA, the seroprevalence in Tibetan pigs were 21.6%, and the prevalence was found 23.1% and 21.4% in males and females, respectively. The results indicates that the Tibetan gigs were exposed to T. gondii in Tibet area, which should arise a public concern of the threat to human and other animals in this unique region of the world.
