Up-regulation of CDR1 and MDR1 efflux pump genes and fluconazole resistance are involved in recurrence in Candida albicans-induced vulvovaginal candidiasis.

Recurrent vulvovaginal candidiasis (RVVC) due to fluconazole resistance in Candida albicans isolates causes a wide range of complications. A number of 63 Candida albicans isolates obtained from vulvovaginal candidiasis (VVC) were identified by Internal Transcribed Spacer-Restriction Fragment Length Polymorphism (ITS-RFLP). Antifungal susceptibility testing was performed by broth microdilution method according to the CLSI protocol.

Molecular epidemiology, antifungal susceptibility, and ERG11 gene mutation of Candida species isolated from vulvovaginal candidiasis: Comparison between recurrent and non-recurrent infections.

Vulvovaginal candidiasis (VVC) is a prevalent infection of the genitourinary tract affecting millions of women worldwide. In the present study, the importance of virulence factors, ERG11 gene mutations, ERG11 gene expression, and plasma membrane ergosterol content for fluconazole resistance in Candida species was investigated in 200 women suspected of vulvovaginitis. Isolated Candida species were identified using the ITS-restriction fragment length polymorphism (ITS-RFLP) technique.
