普洱市部分地区人群弓形虫感染血清流行病学调查

Serological survey of Toxoplasma gondii infection in some areas of Pu'er City

目的掌握云南省普洱市人群弓形虫感染状况,为制定弓形虫病防治策略提供依据。方法选择普洱市景东、景谷和孟连3个县作为调查点,采用ELISA试剂盒检测人群血清弓形虫IgG抗体。结果共检测血清906人份,弓形虫IgG抗体阳性率为24.17%。其中30-岁年龄组和60-岁年龄组IgG抗体阳性率较高,分别为30.30%（60/198）和32.08%（17/53）;不同年龄组间IgG抗体阳性率差异有统计学意义（χ2=17.77,P〈0.01）。不同性别、文化程度、生活习惯之间阳性率差异无统计学意义（P均〉0.05）。农民、学生和其他职业的IgG抗体阳性率分别为26.58%（194/730）、15.49%（22/142）和8.82%（3/34）,差异有统计学意义（χ2=12.51,P〈0.01）;猪饲养具有圈养和散养习惯人群的阳性率分别为23.32%（198/849）和36.84%（21/57）,差异有统计学意义（χ2=5.33,P〈0.05）。结论普洱市部分地区人群弓形虫IgG抗体阳性率较高,应加强弓形虫病的防控和防治知识的健康教育。

Objective To understand the status of Toxoplasma gondii infection in the population of Pu＇er City,so as to provide the evidence for formulating the strategy of toxoplasmosis control. Methods The population from Jingdong,Jinggu,and Menglian counties in Pu＇er City was surveyed;IgG of T. gondii in serum was detected by ELISA. Results Totally 906 resident serum samples were detected and the IgG positive rate was 24.2%. The positive rates were higher in the aged groups of 30-39 years and 60-69 years,and the difference among different aged groups was significant（χ2=17.77,P〈0.01）. There were no significant differences between different sexualities,and among different educational levels and living habits（P〉0.05）. The positive rates were 26.6%（194/730）,15.5%（22/142）,and 8.8%（3/34）in farmers,students and other occupations,respectively,and there was a significant difference among them（χ2=12.51,P〈0.01）. The positive rates were 23.3%（198/849）and 36.8%（21/57）in the farmers who had the habit of rearing pigs in pens and the farmers who had the habit of free ranging pigs,respectively,and there was a significant difference between them（χ2=5.33,P〈0.05）. Conclusion The IgG positive rate of T. gondii is very high in Pu＇er City,and therefore,the health education for toxoplasmosis control should be strengthened.
