Scientists say the risk of Campylobacter infection should be considered by those keeping reptiles as companion animals.
Research published in the Veterinary Record (174:19) suggests pet reptiles could be potential reservoirs of Campylobacter fetus and C hyointestinalis – and therefore may be a source of human infection.
Scientists from the University of Padua, Italy, collected 109 cloacal swabs from captive reptiles during 2011.
Samples were taken from chelonians, lizards and snakes kept in a zoo and a further 67 animals from private households in northern Italy.
The research reported 7.3% of reptiles tested positive for the C fetus sub-species fetus, or C hyointestinalis sub-species hyointestinalis.
These species are known to be pathogenic to people, and C fetus is reported to cause gastroenteritis, septicaemia and disseminated infections. All snakes tested negative.
C hyointestinalis has been isolated from humans and animals and is known to cause gastroenteritis and septicaemia in humans.
Scientists say more research is needed to determine the distribution of the Campylobacter species, the rate of excretion in reptiles and the risk to humans.
