What pathogen is commonly transmitted from pet reptiles to humans?

• A. E. coli
• B. Staphylococcus aureus
• C. Campylobacter
• D. Salmonella

Answer: (D)

Pets like turtles, lizards, and snakes are a classic source of Salmonella for people. Reptiles often carry Salmonella in their intestinal tracts and shed it in feces, so handling the animal or its enclosure can transfer the bacteria to hands, surfaces, or food if proper hygiene isn’t practiced. This makes Salmonella the right choice because reptile-to-human transmission is well established with this organism, whereas the other pathogens are not typically linked to reptiles as a common source. Escherichia coli is a broad gut bacterium usually associated with foodborne illness rather than reptile carriage; Campylobacter is most commonly tied to poultry and undercooked meat; Staphylococcus aureus is mainly involved in skin infections and other non-reptile transmission contexts. Prevention centers on practical hygiene: wash hands thoroughly after handling reptiles or cleaning their enclosures, avoid bringing reptiles into food preparation areas, and keep them away from young children and people with weakened immune systems.
