A rapid assay kit for Vibrio cholerae (Vc) was developed to detect and quantify Vc cells in oyster samples within 24 h. The kit, formulated within a two -phase (liquid and solid) 96-well plate, can detect biomarker expression of Vc when the enrichment broth and incubation temperature are optimized. The kit showed 91 % selectivity and 92 % specificity when tested with 23 inclusive Vc and 106 exclusive non-Vc strains. The kit was further optimized using 47 samples of oysters, clams, and soil. There was no significant difference in most probable number between the kit, conventional PCR and BAX PCR regardless of agar heating method (autoclaved vs. boiled). The kit’s limit of detection was below 5 cfu/g. The kit is a reliable method for the detection of V. cholerae in bivalve samples.
