Variant types of tcdC. VTs with a stop-gain mutation or deletion in the tcdC gene. Each VT has two sequences; the upper sequence is the nucleotide sequence, and the lower sequence is the corresponding amino acid sequence. “-” indicates a deletion; “.” indicates presence of the same base or residue as the reference gene; color indicates bases or residues that differ from the reference gene; “*” with black background indicates a stop codon.
