A pet reptile poses the highest risk of transmitting which infection to humans?

The correct answer is Salmonella. Pet reptiles, such as turtles, lizards, and snakes, are commonly known carriers of Salmonella, which is a type of bacteria that can cause gastrointestinal illness in humans. The transmission can occur through direct contact with reptiles or their environments, as the bacteria can inhabit the reptile's skin and feces.

Humans can become infected through handling these animals, cleaning their habitats, or even through indirect contact via surfaces or items that have been contaminated. The risk of Salmonella transmission is particularly heightened because many reptiles can carry the bacteria without showing any signs of illness themselves, making it difficult to identify a potential source of infection.

While other pathogens listed can affect humans, they are not typically associated with reptile carriers in the same way that Salmonella is. Understanding this risk is crucial for responsible pet ownership and public health awareness regarding reptile handling and hygiene practices.
