Direct molecular typing of Bordetella pertussis from clinical specimens submitted for diagnostic quantitative (real-time) PCR
24 Aug 2012
Abstract excerpt
Molecular typing of Bordetella pertussis is routinely performed on bacterial isolates, but not on DNA extracted from nasopharyngeal aspirates or pernasal swabs submitted for diagnostic real-time PCR (qPCR). We investigated whether these DNA extracts were suitable for multilocus variable-number tandem repeat analysis (MLVA) and DNA sequence-based typing. We analysed all the available qPCR-positive samples received...
