The PCR gel image showing Vibrio cholerae non-toxigenic non-O1 non-O139 sample (32050215) and non-toxigenic O139 sample (52120915) with controls. (A) OmpW CtxA multiplex, ompW, and ctxA simplex reactions. (B) O1 O139 VCT multiplex, O1, and O139 simplex reactions. The bands for cholera toxin (VCT) and O1 are missing for the two samples. The band for O139 is seen but higher than usual (atypical position).
