Persister cells are a small fraction of the microbial population that survive lethal concentrations of antimicrobial agents. causes vaginal candidiasis, including recurrent vulvovaginal candidiasis, and may survive common antifungal treatments. The triazole VT-1161 is an antifungal agent that specifically targets fungal CYP51, as opposed to the human CYP enzyme. This work illustrates a new role of VT-1161 in eradicating the biofilm created from the persister cells of a primary biofilm of a clinical vaginal isolate of . Antifungal activity was determined by the minimum inhibitory concentration (MIC), and the primary biofilm was treated with amphotericin B to obtain persister cells that were able to form a new biofilm. Results obtained using the new azole VT-1161 showed that VT-1161 not only eradicated a secondary biofilm formed from the persister-derived biofilm and counteracted the adhesion of in vitro to human cells but also ameliorated -induced infection in vivo in larvae, suggesting that it could be proposed as an alternative therapeutic strategy for the treatment of recurrent candidiasis.
持留菌是微生物群体中的一小部分,能在致死浓度的抗菌剂中存活。(某种菌)会引发阴道念珠菌病,包括复发性外阴阴道念珠菌病,并且可能在常见的抗真菌治疗中存活下来。三唑类药物VT - 1161是一种抗真菌剂,它特异性靶向真菌CYP51,而非人类CYP酶。这项研究阐明了VT - 1161在根除由临床阴道分离株原始生物膜中的持留菌形成的生物膜方面的新作用。通过最低抑菌浓度(MIC)测定抗真菌活性,并用两性霉素B处理原始生物膜以获得能够形成新生物膜的持留菌。使用新型唑类药物VT - 1161获得的结果表明,VT - 1161不仅能根除由持留菌衍生生物膜形成的次生生物膜,并在体外对抗(某种菌)对人细胞的黏附,还能改善(某种菌)在幼虫体内引发的感染,这表明它可被提议作为治疗复发性念珠菌病的替代治疗策略。
