Fungal overgrowth may be precipitated by what scenario?

• A. Oral antibiotics given to patient that may be immunocompromised
• B. Topical antifungal therapy
• C. Probiotic supplementation
• D. Good oral hygiene

Answer: (A)

Fungal overgrowth happens when the bacteria in the mouth that normally keep fungi in check are reduced or eliminated, allowing fungi to multiply. Oral antibiotics, especially broad-spectrum ones, can drastically reduce these protective bacteria, and in someone who is immunocompromised, the weakened immune defenses make it easier for the fungi to proliferate. That combination of disrupted bacterial balance and reduced immunity creates the perfect scenario for fungal overgrowth, such as oral candidiasis.

Topical antifungal therapy is used to treat established fungal infections, not to precipitate them. Probiotic supplementation aims to support a healthy microbial balance and can help prevent overgrowth, rather than promote it. Good oral hygiene helps reduce microbial load and niches where fungi could thrive, also making overgrowth less likely.
