Comparison of the large tetanus toxin-encoding plasmids. (A) The closed plasmid pE88 of clade 1A strain E88 was used as reference. All other C. tetani genomes were searched against p88. It can be seen that all clade 1A genomes shared the same or a highly similar plasmid, except three strains (ATCC19406, 1586-Z1 and 407-86). The most outer ring depicts genes identified on pE88; important genes are highlighted in color, including tent (in pink) and colT (in light green). All other strains (subclades 1B to 1H and clade 2) carried substantial differences in their plasmids. The following references were taken: (B) the plasmid in clade 2 strain 12124569; (C) the plasmid contig in clade 2 strain 3483; (D) the plasmid contig in subclade 1G strain 132CV; (E) the plasmid contig in subclade 1B strain TMB2. Only comparisons are shown for strains, for which the plasmid sequence was present in a single contig, likely corresponding to the entire plasmid sequence.
