Miconazole is effective against which type of pathogens?

• A. Bacteria
• B. Viruses
• C. Fungi
• D. Parasites

Answer: (C)

Miconazole is an antifungal medication. It blocks a fungal enzyme needed to make ergosterol, a key component of the fungal cell membrane. Without enough ergosterol, the membrane becomes leaky and the fungus cannot grow or survive. Because ergosterol is specific to fungi, miconazole works against fungal pathogens (such as yeasts and dermatophytes) but not bacteria, viruses, or parasites. Bacteria have different targets, viruses require antiviral strategies, and parasitesor other pathogens need different treatments, so miconazole isn’t effective against them.
