Aspergillosis is a common fungal cause of nasal disease in which species?

• A. Dogs
• B. Cats
• C. Horses
• D. Cattle

Answer: (A)

Nasal aspergillosis is most commonly seen in dogs. Aspergillus fumigatus tends to colonize the nasal turbinates in canines, leading to a chronic unilateral nasal discharge, sneezing, and sometimes depigmentation of the nasal planum as the turbinate bones are destroyed. While cats can have fungal nasal disease, it is less common in felines and cryptococcosis is a more typical feline fungal nasal infection. In horses, aspergillosis more often presents as guttural pouch mycosis rather than a primary nasal infection. Cattle rarely develop nasal aspergillosis. So the species most frequently affected by nasal disease due to this fungus is dogs.
