a Type based on [74]

b Crooks contains a related γ4 fimbrial found in E. coli O157:H7 at this location

c Cluster location in E. coli K-12 MG1655

d Cluster located on W pRK1

A '+'means the element is present; a '-' means the element is absent. Where some genes from the cluster are deleted, this is noted as e.g. egoABC. If a different gene fimbria gene cluster is present in the insertion site, the alternative gene cluster is noted. Safe laboratory strains are W (ATCC 9637), K-12 (MG1655), B (REL606), and Crooks (ATCC 8739). W is in phylogroup B1; K-12, B, and Crooks are in phylogroup A.
