Abstract

A new differential medium, CHROMagar Candida, for the isolation of clinically important yeasts was investigated to determine its usefulness in facilitating the study of oral yeasts. The recovery of yeasts on the medium was not significantly different from the recovery on Sabouraud dextrose agar. The identities of 450 green colonies on CHROMagar Candida, presumptively identified as Candida albicans on the basis of the manufacturer's instructions, were confirmed by testing for beta-N-acetylgalactosaminidase. Candida tropicalis also formed distinctive colonies, and other yeasts including Candida (Torulopsis) glabrata, Candida Parapsilosis, Candida Magnoliae, Candida lusitaniae, Candida Famata, Candida kefir, and Saccharomyces cerevisiae were readily distinguished from C. albicans and C. tropicalis isolates. CHROMagar Candida is a very useful medium, and its use will facilitate the study of yeasts associated with dental diseases.

摘要

一种用于分离临床上重要酵母菌的新型鉴别培养基——科玛嘉念珠菌显色培养基,被用于研究其在促进口腔酵母菌研究方面的实用性。该培养基上酵母菌的回收率与沙氏葡萄糖琼脂上的回收率无显著差异。通过检测β-N-乙酰半乳糖胺酶,证实了科玛嘉念珠菌显色培养基上450个绿色菌落的身份,这些菌落在制造商的说明基础上被初步鉴定为白色念珠菌。热带念珠菌也形成了独特的菌落,包括光滑念珠菌、近平滑念珠菌、季也蒙念珠菌、葡萄牙念珠菌、法塔念珠菌、高加索念珠菌和酿酒酵母在内的其他酵母菌很容易与白色念珠菌和热带念珠菌分离株区分开来。科玛嘉念珠菌显色培养基是一种非常有用的培养基,它的使用将有助于研究与牙齿疾病相关的酵母菌。
