Results of a serologic survey for Toxoplasma gondii among 408 Ticuna Indians from five villages in western Brazil are presented and compared with the results of 61 non-Indian inhabitants of the town of Codajas, Amazonas. Indirect hemagglutination antibody titers greater than or equal to 64 were found in 39% of the Ticuna population as compared to 77% of the Codajas population. Prevalence rates of titers greater than or equal to 256 were 20.3% for Ticunas and 39.3% for Codajas. Prevalence rates of titers greater than or equal to 256 in Ticuna villages where dietary habits were most variable were higher and more similar to those of non-Indian populations than were the prevalence rates of this titer range in villages where the animal food source was predominantly fish.
本文展示了对巴西西部五个村庄的408名提库纳印第安人进行的弓形虫血清学调查结果，并将其与亚马逊州科达雅斯镇61名非印第安居民的调查结果进行了比较。在提库纳人群中，39%的人间接血凝抗体滴度大于或等于64，而在科达雅斯人群中这一比例为77%。滴度大于或等于256的流行率，提库纳人为20.3%，科达雅斯人为39.3%。在饮食习惯变化最大的提库纳村庄中，滴度大于或等于256的流行率更高，与非印第安人群的流行率更为相似，而在以鱼类为主食来源的村庄中，这一滴度范围的流行率则较低。
