  • CDS, coding regions.

  • * Based on published values for KIM10+ and CO92; discrepancies between chromosome size versus CDS can be attributed to differences in annotation.

  • For CO92 and KIM10+, numbers in parentheses are pseudogenes identified in this study.

  • In comparisons between IP32953 and either KIM10+ or CO92, the additional CO92-specific filamentous phage is presented in parentheses.
