Diarrhea, straining, loss of appetite and fever are commonly associated with which disease?

• A. Diarrhea
• B. Coccidiosis
• C. Gastroenteritis
• D. Colibacillosis

Answer: (B)

The signs point to an intestinal parasite causing inflammation and irritation of the gut. In coccidiosis, protozoan parasites invade the intestinal lining, damaging the mucosa and triggering inflammation. That disruption leads to diarrhea, and the irritated gut with increased motility makes animals strain to defecate. The gut dysfunction also reduces appetite, and the body’s immune response to the infection can bring a fever. Because these four symptoms together (diarrhea, straining, loss of appetite, and fever) are a classic pattern associated with coccidial intestinal disease, this is the best match among the options. While other conditions can cause similar signs, the combination described most specifically fits coccidiosis, especially in young livestock or poultry.
