Which necropsy finding is commonly associated with clostridial infections in ruminants?

• A. Evidence of tissue hemorrhage
• B. Autoimmune reaction
• C. No gross lesions
• D. Lameness in limbs

Answer: (A)

Clostridial infections in ruminants cause potent toxins that rapidly destroy muscle tissue and damage blood vessels, leading to hemorrhagic necrosis. At necropsy you typically see discolored, hemorrhagic muscle lesions, often with gas formation in the tissue and sometimes subcutaneous emphysema. This pattern of tissue hemorrhage is the most consistent and recognizable gross finding associated with these infections, making it the best choice. Autoimmune reactions don’t usually present as acute, focal gross muscle lesions at necropsy. No gross lesions would be unlikely because clostridial myonecrosis or enteritis commonly produces clear, dramatic tissue damage. Lameness is a clinical sign observed ante-mortem and doesn’t describe a specific necropsy finding of the tissues themselves, whereas hemorrhagic necrosis directly reflects the damage caused by clostridial toxins.
