Black watery mutes are often associated with?

• A. Aspergillosis
• B. Coccidiosis
• C. Trichomonas infection
• D. Overheating

Answer: (B)

Black, watery stools in birds point to coccidiosis, a protozoal infection of the intestinal tract caused by Eimeria species. The parasite damages the gut lining, causing inflammation, hemorrhage, and rapid passage of contents, which can make the feces dark or tar-like and very watery. This pattern is especially common in young birds or those kept in overcrowded, damp conditions with contaminated litter. In contrast, respiratory diseases like aspergillosis produce coughing and nasal discharge, trichomoniasis typically causes lesions in the mouth and throat, and overheating shows up as panting and weakness rather than dark, watery stools. So the association with black, watery stools is characteristic of coccidiosis.
