Candida albicans is a fungus commonly found in the human microbiota, residing on mucous membranes such as the mouth, gastrointestinal tract, and genital area. As an opportunistic pathogen, C. albicans can cause infections, particularly in individuals with weakened immune systems or imbalances in their microbial flora. Conditions like thrush, a fungal infection of the mouth and throat, and vaginal yeast infections are often attributed to C. albicans overgrowth. The fungus can transition between a harmless commensal and a pathogenic form, depending on various factors such as immune function, hormonal changes, and antibiotic use. Invasive candidiasis, a severe form of infection, can occur in immunocompromised patients and may lead to bloodstream infections with potentially life-threatening consequences. Management of Candida albicans infections involves antifungal medications, lifestyle modifications, and addressing underlying health conditions. Prevention strategies include maintaining good hygiene, avoiding unnecessary antibiotic use, and managing conditions that weaken the immune system.
