Amplification method for Yersinia pestis and Yersinia pseudotuberculosis, useful for their rapid detection and differentiation, also new primers and probes

摘要

Amplification and hybridization method for detecting, and/or differentiating between, Yersinia pestis and Y. pseudotuberculosis. Method for detecting, and/or differentiating between, Yersinia pestis and Y. pseudotuberculosis comprises (a) treating a test sample with at least two nucleic acid primers (P1) that bind to a genomic region conserved between the two species; (b) amplification to generate at least one amplicon; (c) contacting amplicon(s) with at least one probe (P2) corresponding to a specific part of the amplified genome from at least one species and able to hybridize specifically to an amplicon, and (d) detecting any hybrids formed. Independent claims are also included for the following: (1) Nucleic acid sequence for detecting and/or differentiating between the specified species; (2) Nucleic acid sequences for controlling an amplification; and (3) Kit for the new method containing two or more nucleic acids of (1) and (2).
