Comparative studies of serotype-specific Clostridium difficile strains

: The following properties of serotype-specific Clostridium difficile strains were studied: toxigenicity, encapsulation, susceptibility to certain antibiotics, biochemical properties, enzymatic activity. No correlation between toxin titer and frequency of capsule production as well as serogroup affiliation and sensitivity to antibiotics was observed. The strain representative of serogroup C attracts attention because of its distinct properties.
