Salmonella infection in pigs typically causes which signs?

• A. Diarrhea with fibrin & blood, leukopenia
• B. Coughing
• C. Vomiting
• D. Seizures

Answer: (A)

Salmonella infection in pigs is primarily an enteric disease. The inflammation of the intestinal lining produces diarrhea that can include blood and fibrin due to mucosal damage and exudate. In acute salmonellosis, endotoxemia can lead to leukopenia, so a combination of diarrhea with blood and fibrin and a reduced white blood cell count fits the typical presentation. Coughing points to a respiratory problem, vomiting isn’t a common feature of swine salmonellosis, and seizures aren’t a typical sign unless there is severe systemic involvement.
