Gastritis due to Helicobacter spp is commonly reported in which species?

• A. Pigs, cats, and dogs
• B. Cattle and horses
• C. Birds
• D. Fish

Answer: (A)

Gastritis caused by Helicobacter species is most commonly reported in pigs, cats, and dogs. In these animals the gastric mucosa is a recognized niche for Helicobacter, with H. suis in pigs and Helicobacter spp. frequently found in dogs and cats associated with chronic gastritis. In cattle, horses, birds, and fish, Helicobacter-like organisms can be present, but the association with gastritis is less consistently reported and the disease connection is not as strong. This makes pigs, cats, and dogs the best-fit group for known Helicobacter-associated gastritis.
