The table presents the number of protein coding sequences (CDS) in each of the 11 Vibrionaceae genomes used in the comparative analysis, the numbers of orthologous groups found in each strain and the number of CDS encoding proteins in the core proteome. The numbers in brackets are the absolute counts. The inter-genomic search yielded a core genome comprised of 1,882 orthologous proteins.
