New multiplex PCR method for the detection of Clostridium difficile toxin A (tcdA) and toxin B (tcdB) and the binary toxin (cdtA/cdtB) genes applied to a Danish strain collection.

Abstract excerpt

Isolates of Clostridium difficile from 159 hospitalized Danish patients (2005) were analysed by a new 5-plex PCR method targeting the toxin genes tcdA, tcdB, cdtA and cdtB, and 16S rDNA as an internal positive control. Additionally, the toxin-regulating gene tcdC was partially sequenced by a new sequencing-based method that revealed genetic changes that may render the gene product inactive. Finally tcdA was...
