Plasmid synteny among pCLK, pCLJ, pCLD and pBf. Three fully sequenced plasmids (pCLK, pCLJ and pCLD) are compared to four contigs of the Bf strain that showed identity to pCLJ by BLASTN analysis. Regions of homology among the bivalent pCLJ, pCLK, pCLD and four pBf contigs is indicated in red and the toxin regions containing of bont/a3, bont/a4 or bont/f are coloured in blue or the bont/bv b and bont/b1 in yellow. The comparisons show the similar location of the bont/bv b and bont/b1among the 3 plasmids. The bont/f and bont/a3 also have similar locations but are inverted in relation to bont/a4. The four Bf contigs include ABDP01000018.1 (84.3 kb), ABDP01000023.1 (68.4 kb), ABDP01000034.1 (16.8 kb), ABDP01000069.1 (0.8 kb) and were ordered according to pCLJ. The coloured symbols are expanded in Figure 10 to detail the genes located in these regions.
