We report 20 episodes of infection caused by acquired echinocandin-resistant Candida spp. harboring diverse and new Fksp mutations. For 12 patients, initial isolates (low MIC, wild-type Fksp sequence) and subsequent isolates (after caspofungin treatment, high MIC, mutated Fksp) were genetically related.
我们报告了 20 例由获得性棘白菌素耐药的念珠菌属引起的感染,这些念珠菌属携带不同的新型 Fksp 突变。对于 12 名患者,初始分离株(低 MIC,野生型 Fksp 序列)和后续分离株(在卡泊芬净治疗后,高 MIC,突变的 Fksp)在遗传上相关。
