This invention discloses primers and a detection method for triple PCR detection of *Morganella morganii*, *
Proteus vulgaris*, and *Providencera reticularis*. The primers are Mm-F, Mm-R, ureC-F, ureC-R, trpD-F, and trpD-R, with
nucleotide sequences shown in SEQ ID NO. 1–6. This invention provides a triple PCR detection method for simultaneously detecting *Morganella morganii*, *
Proteus vulgaris*, and *Providencera reticularis*. This method is highly specific, sensitive, rapid, and accurate, and can be used for clinical and laboratory PCR detection of *Morganella morganii*, *
Proteus vulgaris*, and *Providencera reticularis* in
alligator gout. It has broad application potential in rapid
pathogen detection and epidemiological investigation of
alligator gout.
