近年来从形态学、生理学与生态学等方面进行的分类学研究,获得了很大的进展,逐步明确了物种的概念。我国学者陈世骧(1961)曾对物种的涵义作了精辟的论述,指出“物种是进化单元、是繁殖群体,它是客观存在的;物种是有机世界发展链索上的基本环节,是发展的连续性与间断性统一的基本形式,有机世界以通过物种的形式而发展,以新种的形成为发展的基本环节”。关于溶组织内阿米巴(Entamoeba histolytica)的种株分类问题,随着科学研究的深入而加深对它的认识,本文拟就溶组织内阿米巴种的区分及其宗株区分问题,加以综述,并提出我们的见解。一、溶组识内阿米巴与其他阿米巴种的区分 Dobell(1921)依据前人的研究,描述了寄生在人体肠道的阿米巴有五种:除了具有致病性的溶组织内阿米巴外,尚有非致病性的结肠内阿米巴(Entamoeba coli)、脆双核阿米巴(Dicntamoeba fragilis)、微小内蜓阿米巴(Endolimax nana)和布氏嗜碘阿米巴(lodamoeba
In recent years, taxonomy research conducted in the fields of morphology, physiology and ecology has made great strides and has gradually clarified the concept of species. Chinese scholar Chen Shih-ting (1961) once made a brilliant exposition on the meaning of species, pointing out that "the species is an evolutionary unit, is a breeding group, it is an objective reality; species is the basic link in the organic world development chain, is the development of continuous Sexual and intermittent unity of the basic form of the organic world through the development of species in the form of new species formation for the development of the basic links. With regard to the classification of Entamoeba histolytica species, with the deepening of scientific research to deepen its understanding, this article intends to distinguish between Entamoeba histolytica strains and strains of their classification, to be Summarize, and put forward our opinion. First, the soluble assembly of amoeba and other amoeba identification Dobell (1921) based on previous studies, described parasites in the human intestinal amoeba there are five: In addition to pathogenic lytic tissue Entamoeba coli, Dicntamoeba fragilis, Endolimax nana, and B. amniophilum are the most common non-pathogenic agents of Enterobacteriaceae, (lodamoeba
