There is scarce information concerning the epidemiology of Toxoplasma gondii infection in people of rural Mexico. Anti-T. gondii immunoglobulin (Ig)G and IgM antibodies were sought in 462 adult inhabitants from 3 rural communities of Durango, Mexico, using enzyme-linked immunoassays. In total, 110 (23.8%) of 463 persons had IgG anti-T. gondii antibodies. Ten (2.2%) of them also had IgM anti-T. gondii antibodies. Prevalences of T. gondii IgG antibodies in the 3 communities varied from 14.8 to 35.8%. The highest prevalence of infection was observed in participants older than 70 yr and in those with good housing conditions. Toxoplasma gondii infection was significantly associated with consumption of squirrel (adjusted odds ratio [OR] = 4.22; 95% confidence interval [CI] = 1.11-16.05) and turkey meat (adjusted OR = 4.58; 95% CI = 1.14-18.44). This is the first epidemiological study of T. gondii prevalence in rural Mexico.
关于墨西哥农村地区人群弓形虫感染的流行病学信息匮乏。采用酶联免疫分析法，对来自墨西哥杜兰戈州3个农村社区的462名成年居民进行了抗弓形虫免疫球蛋白（Ig）G和IgM抗体检测。在463人中，共有110人（23.8%）检测出抗弓形虫IgG抗体。其中10人（2.2%）还检测出抗弓形虫IgM抗体。3个社区中弓形虫IgG抗体的患病率在14.8%至35.8%之间。70岁以上参与者以及居住条件良好者的感染率最高。弓形虫感染与食用松鼠肉（校正比值比[OR]=4.22；95%置信区间[CI]=1.11-16.05）和火鸡肉（校正OR=4.58；95%CI=1.14-18.44）显著相关。这是墨西哥农村地区弓形虫患病率的首次流行病学研究。
