Microbe Profile: Candida albicans: a shape-changing, opportunistic pathogenic fungus of humans

Abstract

Candida albicans is normally a harmless commensal of human beings, but it can cause superficial infections of the mucosa (oral/vaginal thrush) in healthy individuals and (rarely) infections of the skin or nails. It can also become invasive, causing life-threatening systemic and bloodstream infections in immunocompromised hosts, where the mortality rate can be as high as 50 %. It is the most common cause of serious fungal infection and is a common cause of nosocomial infections in hospitals. Some strains have been recognized that are resistant to azoles or echinocandins, which are the first-line antifungals for treatment of C. albicans infections.
