Fungal infections caused by yeasts have increased during the last decades and invasive forms represent a serious problem for human health. Candida albicans is the species most frequently isolated from clinical samples. However, other emerging yeast pathogens are increasingly responsible for mycotic infections, and some of them are resistant to some antifungal drugs. Consequently, it is necessary to have methods that can provide a rapid presumptive identification at species level. Numerous chromogenic agar media have been shown to be of value as diagnostic tools. We have compared a chromogenic medium, Brilliance Candida Agar, with CHROMagar Candida, the chromogenic medium most used in our country. A multicentre study was conducted in 16 Hospitals belonging to the Mycology Net of Buenos Aires City Government. A total of 240 yeast isolates were included in this research. The new chromogenic agar showed results very similar to those obtained with CHROMagar Candida.
在过去几十年中，酵母菌引起的真菌感染有所增加，侵袭性感染形式对人类健康构成严重问题。白色念珠菌是最常从临床样本中分离出的菌种。然而，其他新兴的酵母病原体越来越多地导致真菌感染，其中一些对某些抗真菌药物具有抗性。因此，有必要拥有能够在物种水平上提供快速初步鉴定的方法。许多显色琼脂培养基已被证明作为诊断工具具有价值。我们将一种显色培养基—— Brilliance念珠菌琼脂，与我国最常用的显色培养基CHROMagar念珠菌进行了比较。在布宜诺斯艾利斯市政府真菌学网络所属的16家医院进行了一项多中心研究。本研究共纳入240株酵母分离株。新的显色琼脂显示出的结果与CHROMagar念珠菌获得的结果非常相似。
