Which organism is the leading cause of mucosal candidiasis?

• A. Candida albicans
• B. Cryptococcus neoformans
• C. Aspergillus fumigatus
• D. Histoplasma capsulatum

Answer: (A)

Candida albicans is typically the organism responsible for mucosal candidiasis because it is a normal resident of mucosal surfaces and can overgrow when defenses are altered, such as with antibiotic use, immunosuppression, diabetes, or hormonal changes. This overgrowth leads to common mucosal infections like oral thrush and vulvovaginal candidiasis. The other fungi listed cause different diseases: Cryptococcus neoformans is known for meningitis and pulmonary disease in immunocompromised individuals; Aspergillus fumigatus mainly causes pulmonary or sinus infections; Histoplasma capsulatum causes histoplasmosis, typically starting in the lungs and can disseminate. Therefore, the leading cause of mucosal candidiasis is Candida albicans.
