Candida zeylanoides caused candidiasis as tinea cruris in 4 cases. Candida zeylanoides were characterized by good growth of the strain in malt medium, potato dextrose agar and Sabourard's agar. Their colony was milky white and greasy with smooth surface. The diameter of the colony reaches 12 mm within a week. As candida type pseudohyphae but not hyphae, they do not produce ascospore and bolospore. Carbon sources fermentation showed positive results. Nitrogen sources assimilation agar (KNO3) negative, arbutin agar negative, nonvitamin medium positive. G+C mol% value of their DNA was 51.24. Animal experiment showed that guinea pigs were infected by Candida zeylanoides. The main feature of candidiasis as tinea cruris caused by the strain was pink infiltrative erythema with clear margin, a lot of grain-sized papules, a few vesicles, and thin scales. The disease can be cured by preparation of ketoconazole.
锡兰念珠菌引起4例股癣念珠菌病。锡兰念珠菌的特征是该菌株在麦芽培养基、马铃薯葡萄糖琼脂和沙氏琼脂中生长良好。其菌落呈乳白色、油腻，表面光滑。菌落直径在一周内可达12毫米。作为念珠菌属假菌丝而非菌丝，它们不产生子囊孢子和担孢子。碳源发酵呈阳性结果。氮源同化琼脂（KNO₃）阴性，熊果苷琼脂阴性，无维生素培养基阳性。其DNA的G + C摩尔百分比值为51.24。动物实验表明豚鼠被锡兰念珠菌感染。该菌株引起的股癣念珠菌病的主要特征为边界清晰的粉红色浸润性红斑、许多粟粒大小的丘疹、少量水疱和薄鳞屑。该疾病可用酮康唑制剂治愈。
