Reptiles kept as pets are commonly associated with transmission of which pathogen?

• A. Campylobacter
• B. Helicobacter
• C. Salmonella
• D. Vibrio

Answer: (C)

Salmonella is the pathogen most closely linked to reptiles kept as pets. Many reptiles can carry Salmonella in their intestines without showing disease, and the bacteria can spread to hands, cages, bedding, and other surfaces. Humans typically become infected through the fecal-oral route after touching the animal or its environment and then touching the mouth. That’s why strict hand hygiene after handling reptiles, keeping them out of food-preparation areas, and regularly cleaning and sanitizing enclosures are emphasized. Other options aren’t as commonly associated with reptiles: Campylobacter is more tied to poultry and undercooked meat; Helicobacter mainly causes gastric infections; Vibrio is associated with seafood and marine exposure.
