花都区2004年弓形虫病血清学调查

Serological Survey on Toxoplasmosis in Huadu District of Guangzhou City in 2004

目的了解花都区牲畜屠宰及肉类加工销售人员、奶牛场挤奶员、兽医、禽畜饲养员、饲养宠物者等与动物接触密切的重点人群中弓形虫病血清学IgG抗体状况及流行特点,为制订防制策略提供科学依据。方法在区内选择不同职业的人群作为调查对象,采用酶联免疫吸附试验(ELISA)进行弓形虫IgG抗体检测。结果共检测779人,阳性71人,阳性率为9.11%。男女阳性检出率分别为7.84%(33/421)和10.61%(38/358)。不同职业人群之间以挤奶员和牲畜屠宰、肉类加工销售人员阳性率最高,分别为24.00%、13.74%;饲养员、养宠物者次之,阳性率分别为10.00%、9.94%。结论接触动物或进食污染食物易感染弓形虫,必须加强宣传、改变不良习惯、提高个人防护意识等综合防制措施,以降低人群弓形虫感染率。

Objective To examine the occurrence of toxoplasmosis in livestock workers, milker, veterinary, peoples with a close contact with domestic animals in Huadu District of Guangzhou, and to offer strategies for the control of this disease. Method Enzyme-linked immunoserbant assay was used to measure anti-Toxoplasma gondll IgG in these peoples. Result Among the total 779 individuals, 71 subjects （9.11%） had serum antibody against Toxoplasma gondll. The proportion of sero-positive male and female individuals was 7.84% （33/421） and 10.61% （38/358）, respectively. Milkers （24.00%） and meat processing workers （13.73%） had a higher sero-positive rate than the individuals with a close contact with domestic animals（10.00%） or with pets （9.94%）. Conclusion Toxoplasmosis is zoonotic disease. The disease is mainly transmitted through the contacting with the infected animals or through the consumption of contaminated foods. An effective integrated control measure, such as personal hygiene and safety consciousness, may decrease the incidence of infection by Toxoplasma gondii.
