A: Singleplex qPCR results for tcdB, tcdC, and cdtB amplification in the VA17 NAP1/027/BI hypervirulent strain of C. difficile. The tcdB, tcdC, and cdtB amplicons have CT values of 11.8, 15.2, and 11.3, respectively, for a starting concentration of 1.0 ng/μL. B: The corresponding electrophoresis gel plot for PCR performed on the droplet sandwich platform shows, the amplicons are of the appropriate size: 328 bp for tcdB, 282 bp for tcdC, and 190 bp for cdtB. The amplicon size of tcdC indicates the presence of the 18-bp deletion associated with NAP1/027/BI.
