title: Detection of Salmonella and simultaneous detection of Salmonella and Shiga-like toxin-producing Escherichia coli using the magnetic capture hybridization polymerase chain reaction.
abstract: The magnetic capture hybridization polymerase chain reaction (MCH-PCR) was used to detect Salmonella and also to simultaneously detect Salmonella and Shiga-like toxin-producing Escherichia coli (SLTEC). Fifty-seven Salmonella and 41 SLTEC were included in the study. Salmonella were detected either individually by a single MCH-PCR assay targeting the inv gene or simultaneously with SLTEC by a multiplex MCH-PCR in which SLTEC were detected using primers for the slt genes. Both single and multiplex assays were found to be specific for tested pathogens. The results indicate that MCH-PCR can be used as means of detecting single or multiple bacterial pathogen(s).
