BACKGROUND
There is a high rate of Toxoplasma gondii infection worldwide. In Latin America the rate is as high as 65% in some populations.
AIM
To measure the prevalence of antibodies against Toxoplasma gondii in a native Yucpa community in Venezuela.
SUBJECTS AND METHOD
Total serum antibodies measured by indirect hemagglutination and IgM antibodies by ELISA were measured in 94 Yucpa subjects (49 males), aged from 3 months to 100 years.
RESULTS
The overall prevalence of infection was 63%. Fifty nine subjects had total antibodies and 14 had IgM antibodies. No significant differences by age or sex, were observed in the proportion of subjects with positive total or IgM antibodies.
CONCLUSIONS
The studied individuals had a high prevalence of Toxoplasma gondii infection.
背景
全球弓形虫感染率很高。在拉丁美洲，某些人群中的感染率高达65%。
目的
测定委内瑞拉一个尤卡帕土著社区中抗弓形虫抗体的流行率。
对象与方法
对94名年龄在3个月至100岁之间的尤卡帕受试者（49名男性）进行间接血凝法测定血清总抗体以及酶联免疫吸附测定法测定IgM抗体。
结果
感染的总体流行率为63%。59名受试者有总抗体，14名有IgM抗体。在总抗体或IgM抗体呈阳性的受试者比例中，未观察到年龄或性别方面的显著差异。
结论
所研究的个体中弓形虫感染率很高。
