Chromosomal synteny and content comparisons between CG23 completed assemblies. a Homologous regions common to the chromosomes for six completed CG23 chromosomes are represented as blocks. Chromosomal inversions relative to the oldest genome NCTC9494 are indicated by blocks below the line, while blocks above the line indicate the same orientation as the reference. Unique acquisitions that were not common to all genomes are annotated. b Presence (+) or absence (−) of key chromosomal- and plasmid-encoded virulence loci in completed CG23 genomes
