Schematic diagram of the complete whole chromosome and plasmid genomes of the three ST 11 Clostridium difficile isolates. For the chromosome genomes,, the circles (from the out layer inward) represent the genomes, the annotated COG genes on the positive strand, the annotated COG genes on the negative strand, GC content, GC skew, mobile genetic elements (red: the transposons; purple: the CRISPR; green: the prophages), and the name and genome size of the isolates, respectively. For the plasmid genomes,, the circles (from the outer layer inward) refer to GC skew, GC content, reverse strand genes, forward strand genes, all annotated genes and genome size
