Emergence of new PCR ribotypes from the hypervirulent Clostridium difficile 027 lineage.

ABSTRACT: Clostridium difficile is the most common cause of antibiotic-associated diarrhoea worldwide. Over the past 10 years, the incidence and severity of disease have increased in North America and Europe due to the emergence of a hypervirulent clone designated PCR ribotype 027. In this study, we sought to identify phenotypic differences among a collection of 26 presumed PCR ribotype 027 strains from the US and the UK isolated between 1988 and 2008 and also re-evaluated the PCR ribotype. We demonstrated that some of the strains typed as BI by restriction endonuclease analysis, and presumed to be PCR ribotype 027, were in fact other PCR ribotypes such as 176, 198 and 244 due to slight variation in banding pattern compared to the 027 strains. The reassigned 176, 198 and 244 ribotype strains were is
