Fowl typhoid is caused by which Salmonella serovar?

• A. Gallinarum
• B. Pullorum
• C. Enteritidis
• D. Typhimurium

Answer: (A)

Fowl typhoid is the systemic avian disease caused by Salmonella enterica serovar Gallinarum. This serovar is adapted to poultry and tends to cause septicemia in chickens, leading to high mortality, rather than the enteritis more commonly seen with other Salmonella infections. It’s distinct from pullorum disease, which is caused by serovar Pullorum and primarily affects very young chicks. The other serovars listed, such as Enteritidis and Typhimurium, are well-known for causing human foodborne illness and broad host-range infections, but they are not the classic culprits behind fowl typhoid in birds.
