  1. aPresent in the indicated strain(s), but not in any of the other four strains for which genome sequences are available.
  2. bThis group of genes was not detected in the original analysis of the genome from strain J99, but was subsequently detected in strain J99 [43].
  3. cFor this analysis, an island was considered to be present if two or more strain-specific genes were in contiguous chromosomal loci.
