Toxigenic status of Clostridium difficile in a large Spanish teaching hospital.
The aim of this study was to evaluate the toxigenic status of circulating strains of Clostridium difficile in a large teaching hospital. Overall 220 isolates were studied of which 199 (90.5 %) produced both large clostridial toxins detected by conventional methods. Ten more strains (4.5 %) had toxin A and B genes detectable by PCR. Eleven (5.0 %) variant strains (A- B+) were detected among the isolates studied and 10 strains (4.5 %) had the binary toxin genes (cdtA and cdtB).
