Infants are at risk of salmonella infection if the parents own exotic reptiles like snakes, chameleons, iguanas and geckos, reveals a British study published on Monday. Researchers in the southwestern English county of Cornwall found that out of 175 cases of salmonella in children under five over a three-year period, 27 percent occurred in homes which had reptile pets.
Salmonella is a germ that, in humans, can cause gastroenteritis, colitis, blood infections and meningitis.
Reptiles, though, are unaffected by the bug, which colonizes their gut and is passed on in their stools.
If the pet is allowed to run free in the home, this poses a risk, especially if the child is at an exploratory stage of crawling or licking surfaces.
The average age of children who fell ill with "reptile-associated salmonellosis" (RAS) was just six months, said the study, led by Dan Murphy of the Royal Cornwall Hospital in Truro.
"RAS is associated with a severe outcome -- hospitalization and disease," it said.
The investigation is published in a specialized British journal, Archives of Disease in Childhood.
