The perils of pet rats


In my 18 months of taking my turn overseeing the Vancouver Island Health Authority diagnostic microbiology laboratory I have been involved in the diagnosis of 3 cases of Streptobacillus moniliformis infection.

All three were quite serious requiring several days of hospital care. All three involved pet rats. At least 2 of them were not associated with a bite but were associated with very intimate “face to face” contact with the rat. I believe there have been four more cases within the last 3 years diagnosed in our lab. Seven cases in one small city in three years associated with pet rats without bites.

Rat bite fever is a serious infection that can be fatal. All rats have S. moniliformis in their mouths. All rat owners are at risk. It is clear that close contact without a bite can transmit this infection. It seems reasonable that an attempt be made to inform rat buyers of the risk and that there is a role for public health.

Likewise physicians need to be aware of the possibility and ask febrile patients specifically about rat contact.
