BACKGROUND: Toxoplasma gondii is an intracellular protozoan parasite that infects almost all warm-blooded animals, including humans, with a worldwide distribution. There have been limited reports about the seroprevalence of T. gondii infection in equids around the world and little is known about the seroprevalence of T. gondii in equids in southwestern China, in particular in Yunnan Province. The objective of the present investigation was to estimate the seroprevalence of T. gondii infection in equids in this area.
METHODS: A total of 399 serum samples (266 from horses and 133 from donkeys) were collected in 2012, and assayed for T. gondii antibodies by Indirect Haemagglutination (IHA) test using a commercially available kit.
RESULTS: A total of 108 (27.1%) equids, including 81 (30.5%) horses and 27 (20.3%) donkeys were positive for T. gondii antibodies, and the seroprevalence ranged from 18.8% to 37.5% among different sampling areas. The seroprevalence was 27.4% and 26.8% for male and female equids, respectively, and the difference was not statistically significant (P > 0.05). The seroprevalence ranged from 21% to 32.9% among different age groups, and the difference was not statistically significant (P > 0.05).
CONCLUSIONS: The results of the present survey indicated the existence of high T. gondii seroprevalence in Yunnan Province, southwestern China, which has significant public health concern. Therefore, it is imperative that improved integrated measures be carried out to prevent and control T. gondii infection in equids in the studied region.
