阿米巴病是常见传染病之一,尤以热带、亚热带更是普遍。近十多年来对阿米巴的种型、致病力及化学治疗等研究颇有进展,兹简述如下。一、溶组织阿米巴的种型和致病力的研究:这是素有争论而迄今尚未解决的问题。从前认为溶组织阿米巴仅有一种,它是致病的,不过随各地区的原虫株型的不同,或人体肠道生理情况的改变,而表现出各种不同的临床症状;但也有人认为阿米巴在正常情况下寄生在肠腔,也可侵入肠壁而引起病变和症状。后来有人根据流行病学观察,认为阿米巴有二种:1.异型阿米巴,它不致病,分布于温带地区;2.痢疾阿米巴,可致病,分布于热带和亚热带,如这种阿米巴引进温带,也可引起阿米巴痢疾。近十余年来,经进一步研究,又认为阿米巴分为另外的 Amebiasis is one of the common infectious diseases, especially in the tropics and subtropics. Nearly a decade of amoeba species, virulence and chemotherapy and other research quite progress, it is summarized as follows. First, the histological type and virulence of Entamoeba histolytica: This is a controversial issue has so far not been resolved. Historically, there was only one amoebicidal solution of Entamoeba histolytica, which is pathogenic, but exhibits various clinical manifestations depending on the protozoan plant type in each region or the human intestinal physiology; however, some people That amoeba parasites in the intestine under normal circumstances, but also invade the intestinal wall and cause lesions and symptoms. Later, according to epidemiological observation, there are two kinds of amoebae: 1. Abnorm amoeba, it is not pathogenic, located in temperate regions; 2. Diarrhea amoebae, can be pathogenic, located in the tropics and subtropics, Such as the introduction of tempeh amoeba can also cause amoebic dysentery. In the past decade or so, after further study, amoeba was also considered as separate
