阿米巴病是一种细小的寄生性原虫“溶组织阿米巴”感染。大便标本中溶组织阿米巴有两型:在成形大便中发现的主要是包囊(外径10～20μm);在有症状的肠道阿米巴病患者的粘液血便中主要是能活泼运动的滋养体(直径12～50μm)。大便中排出的溶组织包囊对人是直接有感染性的。感染仅能由口吞下包囊而引起。毒力因素对溶组织阿米巴是栖居抑或侵袭的决定因素认识尚不足。然而,人类肠道疾病的发病可能需要有肠道细菌的存在。以溶组
Amebiasis is a small parasitic protozoa “dissolved histolyticamy” infection. There are two types of dissolved histoplasmosis in stool specimens: cysts (10-20 μm in diameter) found mainly in the form of stool; mucus bloody stools in patients with symptomatic intestinal amoebiasis mainly active Of trophozoites (diameter 12 ~ 50μm). Soluble tissue bags that are excreted in the stool are directly infectious to humans. Infection can only be swallowed by the mouth caused by cysts. Virulence factors on the dissolution of amoeba is the habitat or invasion of the understanding of the factors is not enough. However, the development of human intestinal diseases may require the presence of intestinal bacteria. To dissolve group
