Seroprevalence And Risk Factors Associated With Toxoplasma Gondii In Animals From Xinxiang

BackgroundToxoplasmosis is a disease caused by the protozoan Toxoplasma gondii(T. gondii), which infect human and many warm-blooded animals including livestock and poultry. Infection in pigs, cattle and chickens not only result in significant reproductive and economic losses, but also represent an important source of human and other animals infection due to consumption of infected meat, egg and milk. The risk factors associated with T. gondii infection were:age, management, lack of rodent control and presence of cats et al. Research on seroprevalence and risk factors associated with T. gondii in animals is supported for animal cultivation and security supply of human food in future.ObjectivesResearch on seroprevalence associated with T. gondii in pigs, cattle and chickens from Xinxiang,2011-2013; Analysis risk factors associated with T. gondii infection.Methods1. Determination of the best kit of testing antibodies of T. gondii in pigs, cattle and chickens.2. Antibodies to T. gondii in pigs, cattle and chickens from Xinxiang were detected by IHA test kit.3. Questionnaire was developed using closed or open-ended questions at the time of sampling, statistical analysis of risk factors associated with T. gondii infection was performed by chi-square test, using the SPSS 17.0.Results1. The kit of an indirect hemagglutination (IHA) test had higher coincidence with the standard kit (IDVET) than enzyme linked immunosorbent assay (ELISA) kit.2. The seroprevalence of T. gondii infection in pigs from Xinxiang, were 20.9%, 34.4% and 23.9% respectively.10.1%,36.3% and 14.4% were found positive for the presence of T. gondii antibodies in cattle, having statistically significant differences (P<0.05).4.6%,3.1% and 11.1% were found positive for the presence of T. gondii antibodies in chickens, between 2011 and 2013, these seroprevalences were statistically different (P<0.05).3. Seropositivity of T. gondii infection in pigs from Xinxiang associated with presence of cats, lack of rodent control, contacted with dog and history of abortions.Conclusion1. T. gondii antibodies were detected in pigs, cattle and chickens from Xinxiang, between 2011 and 2013.2. Presence of cats, lack of rodent control, contacted with dog and history of abortions are risk factors associated with T. gondii infection in pigs from Xinxiang.
