Blame the Dog: Tracking C. Difficile Infections
Megan Daily writing for MD reported a small Montreal study shows children and in some cases even the family dog play a part in recurrent hospital-acquired Clostridium difficile infections continued spread in the community.

“Our research suggests that household transmission from patients with C. difficile infection could be responsible for a bacterial reservoir for community-associated cases,” said lead author Vivan Loo, McGill University professor, infectious disease specialist and medical microbiologist at the McGill University Health Centre and investigator at its Research Institute.

Published in Infection Control & Hospital Epidemiology “Household Transmission of clostridium difficile to family members and domestic pets” followed 51 patients treated for C. difficile infection in hospital or outpatient settings. Researchers made home visits on a monthly basis and took stool samples from the entire household, including any domestic animals.
The results revealed 13.4 percent of the 67 human household contacts had C. difficile isolated from their stool or rectal samples. One adult household member had diarrhea and the remaining 8 were asymptomatically colonized. Sixty-six percent of those colonized were younger than five years old, including five in diapers.

More than a quarter (26.7 percent) of the 15 domestic pets were asymptomatic carriers of the bacterium, as well.

The study concluded that pets can be reservoirs for re-infection or transmission of C. difficile whose spores can persist in the environment for months and spread through the air with as little effort as it takes to shake out a blanket when changing a patients sheets.
