Antimicrobial drug therapy is the most important risk factor associated with the acquistion of C. difficile, and several antimicrobial agents including clindamycin, amoxicillin, and cepha-lo-sporins have been...
We investigated Clostridium difficile in calves and the similarity between bovine and human C. difficile PCR ribotypes by conducting a case-control study of calves from 102 dairy farms in Canada. Fecal samples from 144 calves with diarrhea and 134 control calves were cultured for C. difficile and tested with an ELISA for C. difficile toxins A and B. C. difficile was isolated from 31 of 278 calv...
Pulsed-field gel electrophoresis (PFGE) after SmaI restriction of DNA from 239 methicillin-resistant Staphylococcus aureus isolates (from 142 patients) produced 26 different fingerprints. The deduced chromosome sizes ranged from 2,200 to 3,100 kb (+/- 100 kb). A total of 81 isolates taken from 65 patients were then typed by PFGE and ribotyping with ClaI, EcoRI, and HindIII. Ribotypes were less ...
