目的了解无锡市重点人群弓形虫感染状况及其影响因素,为制定科学的防治措施提供依据。方法选取无锡市城区艾滋病病毒感染者/病人、肿瘤病人、孕妇、宠物饲养者4类人群为调查对象开展问卷调查,并采血用ELISA法检测抗弓形虫Ig G、Ig M抗体。结果共调查404人,弓形虫抗体阳性38人,总阳性率为9.4%;其中Ig G阳性37人,占97.4%;Ig M阳性1人,占2.6%。多因素分析结果表明年龄、生食食物等不良饮食习惯和接触猫/狗是弓形虫感染的影响因素(OR=2.1、2.6和2.3,P均<0.05)。宠物饲养者、HIV/AIDS和肿瘤病人比孕妇更易感染弓形虫(OR=1.5、8.1和2.8,P均<0.05)。结论无锡市重点人群弓形虫感染率较高,需要采取针对性措施,加强对免疫缺陷、有不良饮食习惯及宠物饲养者等人群的干预工作。
Objective To understand the status of Toxoplasma gondii infection in key populations in Wuxi and its influencing factors so as to provide scientific basis for the development of scientific control measures. Methods Four groups of HIV-infected persons / patients, tumor patients, pregnant women and pet feeders in urban Wuxi were selected as survey subjects. Blood samples were collected for the detection of anti-toxoplasma Ig G and Ig M antibodies by ELISA. Results A total of 404 people were surveyed. Toxoplasma gondii antibody positive 38 people, the total positive rate was 9.4%; Ig G positive 37, accounting for 97.4%; Ig M positive 1, accounting for 2.6%. Multivariate analysis showed that age, raw food and other unhealthy eating habits and cats / dogs were the influencing factors of Toxoplasma infection (OR = 2.1,2.6 and 2.3, P <0.05 respectively). Toxoplasma gondii were more likely to be infected in pet breeders, HIV / AIDS and cancer patients than in pregnant women (OR = 1.5, 8.1 and 2.8, P <0.05). Conclusion The prevalence of Toxoplasma gondii in key population of Wuxi City is high, so it is necessary to take targeted measures to strengthen the intervention on immunodeficiency, poor eating habits and pet feeders.
