Abstract:
:Multiplex PCR and DNA microarray were combined with tyramide signal amplification (TSA) to develop a reliable method suitable for simultaneous detection of six species of human diarrheal pathogens (Yersinia enterocolitica, Shigella spp, Salmonella typhi, Brucella spp, Vibrio cholera and Escherichia coli O157:H7). Meanwhile, our method could distinguish V. cholera serotype O1 from O139, and O157:H7 from O157: non-H7. This assay conferred a specificity of 100% for target pathogens. The limit of detection was 103 degrees CFU/mL approximately. The results of 98.6% (357/362) clinical specimens and 100% (5/5) mocked double-blind samples were the same to that from conventional assay. Consequently this assay is sensitive and a specific tool suitable for diagnostic detection and surveillance of multiple human pathogens.
