In the past decade, researchers have focused on the emergence of drug resistance in fungal pathogens such as Candida albicans, also considered as pathobionts that occur harmlessly in the human body but could potentially be triggered to cause diseases. The increasing rate of antifungal resistance in commensal gut fungi is alarming and should be further investigated. Here, we report seven novel MLST (Multi Locus Sequence Typing) genotypes of multi-drug resistant C. albicans isolates obtained from participants of a community study in Segamat, a district in the state of Johor, Malaysia. A total of eight C. albicans were isolated from four individuals, which were found to express high resistance against fluconazole, itraconazole, voriconazole and 5-fluorocytosine antifungals. MLST was performed to assess the clonal relatedness of these drug resistant isolates among themselves and against other strains isolated from other geographical regions. The novel MLST C. albicans sequence types suggest significant genetic changes compared to previous genotypes.
在过去的十年中,研究人员专注于真菌病原体(如白色念珠菌)耐药性的出现,这些真菌病原体也被认为是人体中的共生菌,通常不会对人体造成危害,但也可能会引发疾病。共生肠道真菌的抗真菌耐药性的增加速度令人震惊,应进一步调查。在这里,我们报告了从马来西亚柔佛州塞格马特区社区研究参与者中获得的七种新型多药耐药白色念珠菌分离株的 MLST(多位点序列分型)基因型。从四个人中总共分离出 8 株白色念珠菌,它们对氟康唑、伊曲康唑、伏立康唑和 5-氟胞嘧啶抗真菌药物表现出高度耐药性。MLST 用于评估这些耐药分离株彼此之间以及与其他地理区域分离的其他菌株之间的克隆相关性。与以前的基因型相比,新型 MLST 白色念珠菌序列类型表明存在重大遗传变化。
