目的了解无锡地区散养鸡的弓形虫感染状况。方法应用ELISA方法调查无锡地区309例散养鸡的弓形虫抗原、抗体阳性率,并与150例集约化养殖鸡的弓形虫感染率进行比较,其中一项阳性即视为弓形虫感染阳性。结果 309例散养鸡中,抗原阳性29例,阳性率为9.39%;抗体阳性53例,阳性率为17.15%;双阳性13例,双阳性率为4.21%;散养鸡总体阳性率为22.33%。集约化养殖鸡总体弓形虫感染率为2.67%。散养鸡感染率显著高于集约化养殖鸡感染率(χ2=29.19,P<0.01)。结论无锡地区散养鸡群弓形虫感染率较高,应引起重视。
Objective To understand the status of Toxoplasma infection in free-range chickens in Wuxi area. Methods Toxoplasma gondii antigen and antibody positive rate in 309 cases of free-range chickens in Wuxi area were investigated by ELISA. The infection rates of Toxoplasma gondii were compared with that of 150 intensive chickens. One of them was considered positive for Toxoplasma gondii infection. Results Of the 309 cases of free-range chickens, the antigen was positive in 29 cases, the positive rate was 9.39%; the antibody positive was 53 cases, the positive rate was 17.15%; the double positive was 13 cases, the double positive rate was 4.21%; the overall positive rate of free-range chicken was 22.33 %. Toxoplasma gondii infection rate of intensive breeding chicken was 2.67%. The infection rate of free-range chicken was significantly higher than that of intensive chicken farming (χ2 = 29.19, P <0.01). Conclusion Toxoplasma gondii infection rates in free-range chickens in Wuxi are higher, which should be paid more attention.
