Isolation of a Toxigenic and Clinical Genotype of Clostridium difficile in Retail Meats in Costa Rica

We isolated a regional toxigenic genotype of Clostridium difficile, previously found in human infection in 4 of 200 (2%) samples of retail meats for human consumption: 1 of 67 samples of beef, 2 of 66 of pork, and 1 of 67 of poultry meat. These four isolates were positive for the tcdA and tcdB genes...

Summary: We isolated a regional toxigenic genotype of Clostridium difficile, previously found in human infection in 4 of 200 (2%) samples of retail meats for human consumption: 1 of 67 samples of beef, 2 of 66 of pork, and 1 of 67 of poultry meat. These four isolates were positive for the tcdA and tcdB genes but negative for deletion of the tcdC and cdtB genes. All strains induced cytopathic effects in HeLa cells. However, they were susceptible to some antibiotics to which clinical isolates are often resistant. All strains were susceptible to vancomycin, metronidazole, moxifloxacin, and rifampicin but resistant to clindamycin and ciprofloxacin. This first report of isolation of C. difficile in foodstuff from Latin America lends support to the notion that animal products serve as a reservoir for clinical strains of this pathogen in the community.
