Authors' Note: Most commonly, we think of asymptomatic carriers as humans who can transmit a microbial infection, but have no symptoms themselves; such diseases as typhoid and salmonellosis are well-known to be transmitted by such carriers.
Similarly, pets may harbor organisms that cause human disease, although the animals themselves don't become ill. Salmonella bacteria are commonly found on the skins of certain lizards and most turtles. The red-eared slider (Trachemys scripta), a reptile native to the US, has attained notoriety in this regard; as children's pets they are cute, easy to care for, and inexpensive. Combined with their penchant for taking over ponds from native turtles, these traits underlie their status as an invasive species whose sale is now banned in many countries around the globe.
