title: Seroprevalence of Toxoplasma gondii infection in pigs, in Zhejiang Province, China.
abstract: Seroprevalence of Toxoplasma gondii infection in pigs in 10 regions of Zhejiang Province, China, was obtained by enzyme-linked immunosorbent assay (ELISA). Anti- T. gondii antibodies were found in 53.4% (434/813) of pigs. Results were analyzed by a chi-square (χ(2)) test. Differences were observed according to farm size, animal age, and sampling regions. Seroprevalences in pigs raised on small farms (71.4%) were significantly higher than that (42.7%) on large farms (P < 0.05), and seroprevalence increased progressively with age. The seroprevalence ranged from 28.1% to 66.0% in different regions, with Jiaxing having the lowest level (28.1%), followed by Hangzhou (36.0%) and Taizhou (42.0%). This is the first study on seroprevalence of T. gondii infection in pigs in Zhejiang Province.
