Comparison of DNA sequence identity of the confidently predicted OMPs from the avian and porcine strain genomes. DNA sequences of the confidently predicted OMPs from the avian strain genome were compared to the confidently predicted proteins from the porcine strain genome using BLAST. The percentage of identity (y-axis) was plotted against the P. multocida avian strain gene IDs and short protein names in parentheses (x-axis). CHP, TonBRep, HP, LP and Autotrans are abbreviations for conserved hypothetical protein, TonB-dependent receptor, hypothetical protein, lipoprotein and autotransporter, respectively. Numbers above the graph indicate the percentage of identity and OMPs are grouped according to the same percentage of identity.
