Abstract |
Clostridium difficile strains isolated from patients hospitalized in the Tokyo Medical and Dental University Teaching Hospital from October 1999 to October 2000 were analyzed by three typing methods; pulsed-field gel electrophoresis (PFGE), PCR ribotyping and PCR toxigenicity. Fifty-five of the 59 isolates were classified into 23 types (A-W) with 34 electrophoretic patterns by PFGE, and all of the isolates were classified into 27 types (a-z, aa) by PCR ribotyping. In the ward in which 70% of C. difficile strains were isolated, the strains with PFGE type A and PCR ribotype a were the most frequently isolated and they were all positive for both toxin A and B. These results suggested that the nosocomial spread of C. difficile had occurred in the particular ward. |
