Abstract: | Fecal samples were collected to establish the apparent prevalence of Clostridium difficile shedding in Standardbred and Thoroughbred racehorses housed at 4 racetracks and 2 breeding facilities, and in horses admitted to a referral large animal clinic. Forty-one (7.59%) of 540 racetrack horses, seven (5.83%) of 120 breeding farm horses, and four (4.88%) out of 82 horses admitted to the referral clinic were culture-positive for C. difficile. An overall fecal culture prevalence of 7.01% for C. difficile was identified in 742 fecal samples. PCR-ribotyping and toxin gene identification was performed and seventeen 17 PCR-ribotypes were identified among the 52 C. difficile isolates. |
