Method for detecting Listeria monocytogenes

摘要

A DNA probe is disclosed which is capable of hybridizing to a portion of the genome of pathogenic Listeria monocytogenes but which does not hybridize to portions of the genomes of other Listeria species and other humilytic bacteria. This probe is useful to identify food sources infected with Listeria monocytogenes and to distinguish these food services from those infected nearly with non-pathogenic Listeria species. In addition, methods for the detection of pathogenic Listeria in samples using the disclosed probes are provided.
