国内猪、牛和鸡弓形虫感染情况及危险因素研究进展

Research Progress of Risk Factors Associated with Toxoplasma gondii in Pigs,Cattle and Chickens and Their Infectious Status in China

通过对国内猪、牛和鸡弓形虫感染情况及危险因素的综述分析发现,各地的猪弓形虫血清阳性率差异较大,其中重庆市猪弓形虫感染阳性率有的高达71.9%;分析认为猪弓形虫感染的危险因素主要是性别、品种、饲养方式和养殖环境等。甘肃省、河南省的牛弓形虫感染率分别为4.8%和5.4%,新疆牛弓形虫血清阳性率最高的达到46.4%;与犬猫接触、年龄及饲养方式等是影响牛弓形虫感染的风险因素。甘肃省、辽宁省的鸡弓形虫感染率分别为7.3%和9.0%,广东的鸡弓形虫感染率最高的达20.3%;鸡弓形虫感染与饲养方式密切相关。

The infectious status and risk factors of toxoplasmosis in the domestic pigs,cattle and chickens were reviewed in this paper.The results showed that the seroprevalence of pigs in different regions were greater difference,and it was as high as 71.9% in Chongqing. Risk factors infected with T. gondii in pigs were gender,breed,style of feeding and hygiene conditions on the farm. The seropositive rates of cattle in Gansu,Henan and Xinjiang were reported to be 4.8%,5.4% and 46.4%,respectively. Contacted with the cats and dogs,age and style of feeding were identified as risk factors of infection with T. gondii in cattle. The seroprevalences of chickens in Gansu and Liaoning were 7.3%,9.0%,respectively,and 20.3% in Guangdong. The toxoplasma infection of chickens was closely related with the feeding models.
