Sera collected from people living along the slopes of Mt. Merapi and Mt. Merbabu (900-1900 m) in Boyolali Regency, Central Java, Indonesia were tested by indirect hemagglutination tests for antibodies to Entamoeba histolytica and Toxoplasma gondii. A total of 695 sera from 439 males and 256 females, 2 to 75 years of age were tested for amoebiasis and 17.6% had positive antibody titers of 1:128 or greater. The prevalence of antibodies was the same for males and females and increased with age. The seropositivity rate for Toxoplasma gondii antibodies among 438 males and 255 females was 2% at titers of 1:256 or greater. The prevalence was higher in females (2.7%) than in males (1.6%), and was highest in the oldest age groups.
从印度尼西亚中爪哇省博约拉利县默拉皮山和默巴布山（海拔900 - 1900米）山坡居民采集的血清，通过间接血凝试验检测溶组织内阿米巴和刚地弓形虫抗体。共检测了439名男性和256名女性（年龄在2至75岁之间）的695份血清中的阿米巴病情况，17.6%的人抗体滴度为1:128或更高呈阳性。男性和女性的抗体流行率相同，且随年龄增长而增加。在438名男性和255名女性中，刚地弓形虫抗体滴度为1:256或更高时的血清阳性率为2%。女性的流行率（2.7%）高于男性（1.6%），且在年龄最大的组中最高。
