目的了解江苏省特殊人群弓形虫感染情况,为制定科学的防治措施提供依据。方法采用酶联免疫吸附试验检测特殊人群血清弓形虫IgG抗体,并配以相应的对照组作比较分析。结果人群血清弓形虫IgG抗体阳性率为7.19%,其中特殊人群抗体阳性率为8.30%,对照组阳性率为6.08%,有显著性差异(P<0.05),献血员和临床免疫功能低下者与对照组相比OR分别为4.67和6.67(P<0.05)。结论江苏省特殊人群血清弓形虫抗体阳性率高于普通对照组人员,献血员和临床免疫功能低下者与弓形虫感染有关联性。提示对特殊人群的重视,尤其是应加强对献血人员的弓形虫抗体检测以及对免疫功能低下者的保护。
Objective To understand the situation of Toxoplasma gondii infection in special populations in Jiangsu Province, and to provide evidence for the establishment of scientific prevention and control measures. Methods Serum Toxoplasma gondii IgG antibodies were detected by enzyme-linked immunosorbent assay (ELISA), and compared with the corresponding control group for comparative analysis. Results The positive rate of Serum Toxoplasma gondii IgG was 7.19% in the population, the positive rate of antibody in special population was 8.30% and the positive rate in control group was 6.08% (P <0.05). The blood donors and clinical immunocompromised patients were The ORs in the control group were 4.67 and 6.67, respectively (P <0.05). Conclusion The positive rate of Toxoplasma gondii antibody in special population of Jiangsu Province was higher than that of the control group. The blood donors and clinical immunocompromised persons were associated with Toxoplasma gondii infection. Prompted attention to special populations, in particular, should be strengthened to test blood donors Toxoplasma antibodies and immunocompromised persons.
