Vibrio parahaemolyticus is a marine seafood-borne pathogen that causes gastrointestinal disorders in humans. In this study, we developed a cross-priming amplification (CPA) assay coupled with vertical flow (VF) visualization for rapid and sensitive detection of V. parahaemolyticus. This assay correctly detected all target strains (n = 13) and none of the non-target strains (n = 27). Small concentrations of V. parahaemolyticus (1.8 CFU/mL for pure cultures and 18 CFU/g for reconstituted samples) were detected within 1 h. CPA-VF can be applied at a large scale and can be used to detect V. parahaemolyticus strains rapidly in seafood and environmental samples, being especially useful in the field.
副溶血性弧菌是一种通过海产品传播的海洋病原体，可导致人类胃肠道疾病。在本研究中，我们开发了一种结合垂直流（VF）可视化的交叉引物扩增（CPA）检测方法，用于快速、灵敏地检测副溶血性弧菌。该检测方法正确检测出了所有目标菌株（n = 13），且未检测出任何非目标菌株（n = 27）。在1小时内检测到了低浓度的副溶血性弧菌（纯培养物中为1.8 CFU/mL，复溶样品中为18 CFU/g）。CPA-VF可大规模应用，可用于快速检测海产品和环境样品中的副溶血性弧菌菌株，在现场尤其有用。
