Fluconazole is commonly used to treat which fungal infection in companion animals?

• A. Blastomyces dermatitidis
• B. Histoplasma capsulatum
• C. Aspergillus fumigatus
• D. Coccidioides immitis

Answer: (D)

Fluconazole is chosen here because it has good oral bioavailability and distributes well throughout the body, including the central nervous system and ocular tissues. This makes it useful for managing coccidioidomycosis in dogs and cats, where long-term oral therapy is common and dissemination to various sites can occur. While fluconazole works for some fungal infections, it is less reliable against the other systemic dimorphic fungi and molds. For Blastomyces dermatitidis and Histoplasma capsulatum, itraconazole is typically preferred due to stronger activity in those organisms, and for Aspergillus fumigatus, drugs like voriconazole are usually more effective. Thus, fluconazole is commonly used for Coccidioides immitis in companion animals.
