Which finding is NOT characteristic of bacillary hemoglobinuria in cattle?

• A. Hemoglobinuria and hepatic infarct
• B. Diarrhea and dehydration
• C. Neurological signs
• D. Cough and nasal discharge

Answer: (D)

Bacillary hemoglobinuria is driven by a clostridial toxin (from Clostridium haemolyticum) that causes intravascular hemolysis and multifocal hepatic necrosis (infarcts). Clinically, you see red or brown urine from hemoglobinuria, signs of anemia (weakness, pale mucous membranes), and often dehydration, with hepatic infarcts contributing to systemic illness. Diarrhea and dehydration can be part of the illness, and neurological signs can occur secondary to anemia or systemic toxicity, but they are not the hallmark features. Cough and nasal discharge, however, point to a respiratory issue and are not associated with this hepatic clostridial infection. So the finding that does not fit is coughing with nasal discharge.
