title: Seroprevalence and Risk Factors of Toxoplasma gondii Infection in Farmed Raccoon Dogs (Nyctereutes procyonoides) in China.
abstract: Toxoplasma gondii, an obligate intracellular apicomplexan parasite, can infect homoiothermal vertebrate animals, including raccoon dogs (Nyctereutes procyonoides). Regretfully, data on T. gondii infection in raccoon dogs were limited in China. Therefore, to investigate the seroprevalence and to evaluate risk factors for T. gondii infection in raccoon dogs, a total of 1181 raccoon dog blood samples were collected from Jilin and Shandong provinces, China, from September to December 2014. The antibodies of T. gondii were examined using the modified agglutination test. Overall, the seroprevalence of T. gondii infection was 8.64% in the examined raccoon dogs. The prevalences of T. gondii infection were different among cities (ranging from 2.96% in Yantai to 17.62% in Qingdao), genders (female: 7.58%; male: 9.22%), and ages (young: 8.53%; subadult: 7.71%; adult: 7.73%). Region was considered as an important risk factor for T. gondii infection in this study. This is the first report of T. gondii infection in raccoon dogs in China, providing baseline information for prevention and control of T. gondii infection in raccoon dogs in Jilin and Shandong provinces, China.
