Salmonella is considered a natural compound of reptile gastrointestinal tract flora and the rate of asymptomatic carriers can reach 100%. The prevalence varies in tested populations and depends on many factors, such as habitat, diet, intermittent shedding, but also on the culture method used in the study. Reptiles carry a wide variety of Salmonella serotypes including those specific for cold-blooded animals, but also those belonging to Salmonella enterica subsp. enterica. Salmonella in reptiles may be transmitted both horizontally by direct contact between individuals or via a contaminated environment as well as vertically. Colonized reptiles are considered a human health risk and direct contact is not a prerequisite for transmission. Infants, pregnant women, elderly and immune-compromised persons are at an increased risk for reptile-associated Salmonella infections. Detailed studies are necessary to evaluate the prevalence in pet reptile populations and potential consequences for humans.
