目的了解深圳市野生动物驯养人员的弓形虫感染状况。方法采用整群抽样方法,对深圳动物园的野生动物驯养人员进行血清CAg、IgM和IgG的ELISA检测,并统计学分析其感染特征。结果共调查动物园野生动物驯养人员204人,CAg循环抗原、IgM抗体和IgG抗体的阳性率分别为2.45%、4.90%和9.31%,三项合并后的总阳性率为13.73%,高于我国各地的人群平均阳性率。在同一动物园不同工作区域工作的驯养人员的弓形虫感染率没有显著性差异,但女性的IgG阳性率和总阳性率比男性高,工龄较短者的IgM阳性率比工龄较长者高,而工龄较长者的IgG阳性率比工龄较短者高。结论动物园野生动物驯养人员是弓形虫病防治的重点人群,野生动物在弓形虫的传播中起着重要的媒介作用。
Objective To understand the Toxoplasma infection status of domesticated animals in Shenzhen. Methods The cluster sampling method was used to detect the serum CAg, IgM and IgG in domesticated animals of Shenzhen zoo. The infection characteristics were statistically analyzed. Results A total of 204 domesticated animals were enrolled in the zoo. The positive rates of CAg circulating antigen, IgM antibody and IgG antibody were 2.45%, 4.90% and 9.31% respectively. The positive rates of the three combinations were 13.73% The average positive rate of the crowd. There was no significant difference in Toxoplasma infection rates among domesticated workers working in different work areas in the same zoo. However, the positive rate of IgG and the positive rate of IgG were higher in women than in men, and the positive rates of IgM in those with shorter working age were higher than those in older ones Those with longer working age have a higher positive rate of IgG than those with shorter working age. Conclusion The zoo wildlife domesticated personnel are the key population for the prevention and control of toxoplasmosis. Wild animals play an important role in the transmission of toxoplasma.
