a

Boldface type indicates cnf1-positive isolates; italic type indicates the strain shared by case 1 (lung, liver) and a healthy dog (feces). ExPEC, extraintestinal pathogenic E. coli; ND, not done; ST, sequence type. +, present; −, absent.

b

One representative isolate is shown per unique strain (i.e., pulsotype), regardless of how many hosts the strain was isolated from.

c

ST was determined if a strain was from phylogroup B2 or exhibited an ExPEC-associated O type (O2, O4, O6, O7, O15, O16, O18, O25, O75).

d

For strains with no O type result after a PCR-based screen, O:H serotyping was done. Isolates with footnote symbol: PCR-based O type.

e

All strains had fimH (type 1 fimbriae). None had afa/draBC (Dr-binding adhesins), bmaE (M fimbriae), cdtB (cytolethal distending toxin), clpG (variant adhesin), F17 (variant adhesin), gafD (G fimbriae), iha (adhesin-siderophore), K2/K100 (group 2 capsule variants), K5 (group 2 capsule variant), K15 (group 2 capsule variant), papG allele II (variant P fimbriae adhesin), sat (secreted autotransporter toxin), or tsh (temperature-sensitive hemagglutinin).

f

This strain lacked papAH.
