Abstract
The incidence of fluconazole-resistant Candida albicans has been increasing worldwide. Both biofilm and fungal morphogenesis are main virulence factors of C. albicans cells. Extracellular fungal prostaglandins are synthesized during biofilm adhesion and development and through yeast-hypha conversion. Hence, we targeted prostaglandin synthesis with various cyclooxygenase (COX) inhibitors (aspirin, diclofenac, ketoprofen, tenoxicam, and ketorolac) and assessed their effect on fungal adhesion, biofilm formation, and yeast-hypha conversion in clinical isolates of Fluconazole resistant C. albicans. Significant reduction in fungal adhesion and detachment of mature biofilm was attained down to 1 mM concentrations of anti-inflammatory agents. Microscopical examination of fungal cells in the presence of the tested drugs showed significant reduction of germ tube formation. Therefore, COX inhibitors have a significant effect on reduction of Candida adhesion and biofilm development in correlation with fungal morphogenesis. Moreover, inhibition of C. albicans by COX inhibitors gave synergistic activity with fluconazole suggesting that combination therapeutic strategies may be fruitful for management of infection of Fluconazole resistant C. albicans.Entities:
