Rapid and sensitive detection of Plesiomonas shigelloides by cross‑priming amplification of the hugA gene.

ABSTRACT: Plesiomonas shigelloides (P. shigelloides) is implicated as an aetiological agent of human gastroenteritis in humans, for which reliable laboratory detection of P. shigelloides is clinically and epidemiologically desirable. A simple molecular method for rapid detection of P. shigelloides using cross‑priming amplification (CPA) has been developed, with hugA as the target. The hugA gene is required for haem iron utilisation and is critical for the survival and growth of P. shigelloides. The assay output was visualised as a colour change with no need to open the reaction tubes, and no false‑positive results were detected for the 33 non‑ P. shigelloides strains examined to assess assay specificity. The limit of detection was 200 fg P. shigelloides DNA per reaction and 3x103 CFU per g in human
