霉菌寄生于溶组织内阿米巴体内的观察

从铁苏木素染色的一张粪便涂片标本中,发现溶组织内阿米巴包囊被虫藻壶菌属霉菌寄生的占78％,而且成熟的四核包囊甚少。包囊内的霉菌分散或成群,多数形成孢子囊。寄生部位在细胞质内、糖原块内或拟染色体上。并查见霉菌寄生于结肠内阿米巴包囊的占18％,微小内蜒阿米巴包囊的占11％。哈门氏内阿米巴包囊16个,发现1个有霉菌寄生。

Report on a fungus parasitizing Entamoeba histolytica

Infection of Entamoeba histolytica with chytridiaceous fungus Sphaerita was observed in some specimens obtained from a farmer and stained with iron-haematoxylin. The fungi were found in 78% of the cysts, mostly immature ones. Within the amoebae this parasite occurred singly, in groups, or in the form of a sporangium. It was located in the cytoplasm, the glycogen mass or the chromatoidal bars. In the same specimen, the parasitic fungus was also found in 18% of E. coli cysts; in 11% of E. nana cysts; while only one of 16 E. hartmanni cysts was parasitized. It is an interesting case of superimposed parasitism so far reported in China as well as a rare case of several species of amoebae being heavily involved with the same in the scientific literature.
