Abstract

A simultaneous screening method using conventional PCR was developed for the detection and discrimination of Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii. A formulated multiprex method employing 4 kinds of paired primers on amplification of 4 corresponding different insertion sequences (IS481, IS1001, IS1002 and hIS1001) enabled rapid screening and identification. The detection limits of each DNA extracted from 3 kinds of Bordetella species were 5fg/microL for each. Obscure existences of B. pertussis and B. holmesii at low levels were confirmed with the LAMP method. This multiplex assay was applied to the clinical specimens obtained from patients with pertussis-like symptoms at sentinel clinics under the epidemiological surveillance of infectious diseases of Hyogo prefecture in FY2012. Among 42 nasopharyngeal swabs, B. pertussis was detected from 12 samples including 8 samples collected at outbreak in nursery school. The use of this method for the surveillance of infectious agents enabled us to search for 3 kinds of Bordetella species at once with low costs.
