A serological survey was conducted in the villages of Phichit Province, Northern region and in the urban slum communities in Bangkok to determine whether amoebiasis was endemic in the areas and to determine the prevalence rates. Six rural villages, ethnically and culturally alike with a population of 3,019 and two urban slums with a population of 1,510 were surveyed. Sera were tested for indirect hemagglutination antibody (IHA) to Entamoeba histolytica and the stools examined for the parasite by direct smear method. Positive IHA titres (greater than or equal to 1:128) were detected in 482 (11%) and 176 (20%) sera, and E. histolytica found in 639 (2%) and 208 (3%) stool specimens of rural and urban slum populations respectively. Out of a total of 88 persons who showed significant levels of IHA antibodies to E. histolytica antigen, 5 had E. histolytica cysts in their stool specimens. The survey confirmed, serologically and parasitologically, that amoebiasis is endemic in the lower socio-economic areas. Substandard living and sanitary conditions within the areas were considered responsible for the transmission of the disease.
在北部地区的披集府村庄以及曼谷的城市贫民窟社区开展了一项血清学调查，以确定这些地区是否存在阿米巴病地方流行情况，并确定其患病率。对6个种族和文化相似、人口为3019人的乡村以及2个人口为1510人的城市贫民窟进行了调查。检测血清中针对溶组织内阿米巴的间接血凝抗体（IHA），并通过直接涂片法检查粪便中的寄生虫。在乡村和城市贫民窟人群的血清中，分别有482例（11%）和176例（20%）检测到阳性IHA滴度（大于或等于1:128），在粪便标本中分别有639例（2%）和208例（3%）发现溶组织内阿米巴。在总共88例对溶组织内阿米巴抗原显示出显著水平IHA抗体的人中，有5人的粪便标本中含有溶组织内阿米巴囊肿。该调查从血清学和寄生虫学方面证实，阿米巴病在社会经济水平较低的地区呈地方流行。这些地区生活和卫生条件不达标准被认为是该病传播的原因。
