^aPotential ExPEC-associated virulence genes were taken from references 88 and 89.

^b+, the gene is present and the coding sequence is intact; −, the gene is absent; ±, the gene is present but not functional.

^cBased on the current MP1 genome sequence, the picU gene has a frameshift caused by a single base deletion.
