犬新孢子虫是一种原生动物寄生虫，它会导致牛流产，也会导致繁殖问题和狗的神经紊乱。狗在犬奈瑟菌的流行病学中很重要，因为它们作为最终宿主，在环境中脱落卵囊。为调查中部地区犬犬犬犬感染的血清流行情况，于2015年3月至2016年2月在河南省采集了1176份犬血清，采用间接荧光抗体法（IFAT）检测犬N.犬IgG抗体。总血清阳性率接近15%（172/1176）。不同犬种、性别的血清阳性率差异无统计学意义（p < 0.05）。农村犬感染率（18%）高于城市犬（11%）（p < 0.05）。犬链球菌感染患病率随年龄增长而增加（p < 0.05）。本研究结果表明，河南省犬类中犬链球菌抗体的流行率较高。必须改善卫生条件和动物健康，以防止犬传播犬奈瑟菌的风险。
Neospora caninum is a protozoan parasite that causes abortion in cattle as well as reproduction problems and neurological disorders in dogs. Dogs are important in the epidemiology of N. caninum because they act as definitive hosts, shedding oocysts in the environment. To investigate the seroprevalence of N. caninum infection in dogs in central China, 1176 serum samples were collected from domestic dogs in Henan province, central China between March 2015 and February 2016 and tested for IgG antibody against N. caninum, using the indirect fluorescent antibody test (IFAT). The overall seroprevalence of N. caninum was nearly 15% (172/1176). No significant difference was observed between this seroprevalence according to sex and breed of dogs (p > 0.05). The infection rate in rural dogs (18%) was higher (p < 0.05) than in urban dogs (11%). The prevalence of N. caninum infection in dogs increased (p < 0.05) with age. The results of the present study indicate the high prevalence of N. caninum antibodies in dogs in Henan province, central China. Sanitary conditions and animal health must be improved to prevent the transmission risk of N. caninum by dogs.
