十堰地区人群弓形虫血清流行病学研究

Sero-epidemiologic Investigation on the Infection of Toxoplasma Gondii among Population in Shiyan Area

目的:调查十堰地区人群弓形虫感染的现状和动态,为制定科学防治对策提供依据。方法:采用问卷方式调查居民的性别、年龄、文化程度、职业及卫生习惯等;采用ELISA方法检测人群血清弓形虫IgG抗体。结果:十堰地区人群弓形虫IgG抗体阳性率为8.21%。市区人群IgG抗体阳性率高于各县(市)人群,猫犬等动物密切接触者,临床免疫功能低下者和不良饮食卫生习惯者阳性率高于其他人群。结论:十堰地区居民弓形虫感染率较高,喂养宠物及不良饮食习惯是弓形虫感染的重要因素。应采取健康教育、早期检查及治疗等综合性预防控制措施,并加强对重点人群的监测。

Objective To investigate the current status and trend of toxoplasma gondii(T.gondii) infection among population in Shiyan area,so as to provide the scientific basis for establishing control strategy of the disease.Methods Questionnaire was carried out to collect information including gender,age,occupation and life style.The IgG antibody of T.gondii in serum from residents was detected by ELISA.Results The average positive rate of IgG antibdy of T.gondii was 8.21% in Shiyan area.The positive rate of IgG in town and city was significantly higher than that of urban district area.The positive rates of three kinds of population(population with contacting cat and dog frequently,population with lower immunity function,and population with bad dietetic habits) were all higher than other populations.Conclusion Integrated control strategies,such as health education,early examination and treatment,and improvement of environment should be adopted to control infection of T.gondii,and the surveillance among susceptible population should be strengthened at the same time.
