自1912年 Brumpt 将人酵母菌命名为 Blastocystishominis 归属于酵母菌以来,一直认为其对人体是无害的,唯一的重要性是在形态上与溶组织阿米巴相似,粪检时需要鉴别。最近根据其生物学特性和超微结构的一些特点将其归为肠道寄生原虫。且有许多文献对其致病性,流行病学等进行了调查。为了解人酵母菌在我国的流行情况及临床特征,我们于1990年7～8月在焦作地区进行了调查,并对其单纯感染者进行了治疗。 Since 1912, Brumpt named human yeast Blastocystishominis vested in yeast has been considered harmless to humans, the only importance is the morphological and amicable solution of amoeba, need to identify the fecal examination. It has recently been classified as an intestinal parasitic protozoa based on some of its biological characteristics and ultrastructural features. There are many articles on its pathogenicity, epidemiology and other investigations. In order to understand the prevalence and clinical characteristics of human yeast in our country, we conducted a survey in Jiaozuo from July to August 1990, and treated patients who were simply infected.
