摘要: 耳念珠菌是近年新发现的念珠菌种, 在部分国家尤其是美国呈现耐药性及院内感染暴发态势。"超级病原"及其引申出来的"超级真菌"在真菌领域罕被提及, 但近来"耳念珠菌是超级真菌"的言论却在互联网上广为流传。现有报道及其流行病学监测数据显示, 中国耳念珠菌临床发生发展情况与美国不同, 其所引发的感染仍属个案, 且药物敏感度高, 致病性不强于常见非-白念珠菌。因此, 公众无需过度解读, 以致产生不必要的恐慌。Abstract: Candida auris is an emerging pathogen in recent years that has developed resistance and caused nosocomial outbreaks in some countries especially in the United States. The term "super fungi" derived from "superbug", and it is rarely mentioned in the field of fungi. However, recently the articles with the definition that "Candida auris is a super fungi" are widely circulated on the internet. The situation of Candida auris in China differs from that in the United States according to existing reports and epidemiological surveillance data. The infection caused by it is still sporadic, and isolations of Candida auris are active to antifungal agents. Meanwhile, its pathogenicity is not stronger than the common non-albican Candida species. Therefore, the public should avoid excessive interpretation of the articles with unnecessary panic.
