a
The start and end positions of regions that are absent from the K-12 chromosomal backbone are given by the gene identifier and gene name (in parentheses), where applicable. Strains belonging to the O26 serotype are shown in bold. The names of some clinical isolates have been shortened by omitting the suffix. ∗, strain in which the missing region has a significant overlap but starts before or extends beyond or is not as large as the positions given but is still missing at least 10 consecutive genes.
