Detection of Morganella morganii, a prolific histamine former, by the polymerase chain reaction assay with 16S rDNA-targeted primers.

A polymerase chain reaction (PCR) assay for the rapid and sensitive detection of the most prolific histamine former, Morganella morganii, was developed. 16S rDNA targeted PCR primers were designed, and the primer specificity and sensitivity of the PCR assay were evaluated. The 16S rDNA sequence (1,503 bp) for M.
