Biofilms and vulvovaginal candidiasis

Area of Science:

• Mycology
• Infectious Diseases
• Microbiology

Background:

• Candida species are common mucosal flora, but can cause symptomatic vulvovaginal candidiasis (VVC) under certain conditions.
• While Candida albicans was historically the primary cause, other species like C. glabrata, C. parapsilosis, C. krusei, and C. tropicalis are increasingly implicated in VVC.
• The precise mechanisms by which Candida species induce inflammation in VVC remain unclear.

Purpose of the Study:

• To review the role of Candida species, particularly Candida albicans, in vulvovaginal candidiasis (VVC).
• To explore the significance of biofilm formation as a virulence factor in VVC.
• To discuss key aspects of Candida biofilms relevant to VVC pathogenesis and treatment resistance.

Main Methods:

• Literature review focusing on Candida species and vulvovaginal candidiasis.
• Analysis of studies examining biofilm structure, development, and associated gene expression.
• Review of research on cell surface adherence, extracellular matrix, metabolism, and drug resistance in Candida biofilms.

Main Results:

• Candida species can invade vaginal epithelium via blastoconidia and pseudohyphae.
• Biofilm formation by Candida species confers increased resistance to antifungal agents.
• VVC is generally associated with higher fungal burden and pseudohyphae presence.

Conclusions:

• Candida biofilms represent a critical virulence factor in vulvovaginal candidiasis.
• Understanding biofilm dynamics is essential for addressing VVC, especially infections with emerging Candida species.
• Further research into biofilm-associated gene expression, metabolism, and drug resistance is warranted for effective VVC management.
