摘要：
Background. Chickens serve as an intermediate host for Toxoplasma gondii and Neospora caninum; infection of free-range (FR) chickens with these organisms is a useful indicator of soil and environmental contamination with oocysts. A total of 700 FR chicken serum samples and 300 heart samples were collected from Henan province from March to July 2015. Antibodies to T. gondii were found in 18.86% (132/700) of the chickens by modified agglutination test (cut-off 1 : 25), while 23.14% (162/700) were positive for N. caninum by indirect fluorescent antibody test (cut-off 1 : 25). T. gondii DNA was detected in the myocardium digestion liquids of 4/25 (16%) FR chickens. The PCR results of N. caninum DNA from FR chicken myocardium digestion liquids (n = 25) were all negative. Attempts to isolate viable T. gondii were unsuccessful. The results showed that there were antibodies to T. gondii and N. caninum in FR chickens from Henan province. Accordingly, effective control of feces from cats and dogs and improved pets hygiene habits were needed. To the author's knowledge, this is the first report of the presence of N. caninum antibody in chickens from China.
