Candidiasis is found in the esophagus and crop of birds and is characterized by raised patch of necrotic tissue, which has a foul odor.

• A. Only in skin
• B. Patch is not necrotic
• C. False
• D. True

Answer: (D)

Candidiasis in birds primarily invades the mucosa of the upper digestive tract, especially the crop and esophagus. It presents as white, raised patches on the mucosal surface that are necrotic and often have an unpleasant, foul odor due to tissue decay and fungal growth. This directly matches the statement, so it is true. It isn’t limited to the skin, and the lesions described are indeed necrotic, not non-necrotic, so those alternative descriptions don’t fit. In practice, recognizing these signs helps distinguish candidiasis from other crop diseases and guides appropriate antifungal treatment and supportive care.
