a

Clusters and subclusters were resolved by similarity relationship analysis (UPGMA).

b

Source, epidemiological sources: P, patients with pyelonephritis; S, cancer patients with sepsis; E, animals with extraintestinal infections; I, animals with intestinal infections; Stx, intestinal infections with STEC strains.

c

ARS, antibiotic resistance score, which corresponds to the number of agents to which the strains were found to be resistant (28).

d

SR, serum resistance; +, survival in fresh human serum; −, killing by fresh human serum.

e

afa-8, afa-8 operon location; P, plasmid; C, chromosome; ND, not determined.

f

For VF genes, + and − indicate the presence or absence of the given gene, respectively. Putative VF genes are further described as follows: kpsMT II, group II capsule synthesis; pap, papAH, papC, papEF; for papG, III, allele III; II, allele II; rs, papGrs; clpG, major subunit of CS31A; for f17A, a, b, and c indicate alleles f17Aa, f17Ab, and f17Ac, respectively; sfa, central region of the sfa/foc operon; iha, nonhemagglutinating adhesin-associated PAI ICFT073; hly, hemolysin; for cnf, 1, cytotoxic necrotizing factor type 1; 2, cytotoxic necrotizing factor type 2; east1, enteroaggregative E. coli heat-stable enterotoxin 1; stx, STEC markers sepB and stx; iutA, aerobactin; iroN, catechole siderophore receptor-associated PAICP9; HPI, pathogenicity-associated island markers irp1, irp2, and fyuA from pathogenic Yersinia HPI; int, HPI integrase gene (D, truncated int gene; N, intact int gene); modD, molybdenum transport; PAI, pathogenicity-associated island markers malX and cysB from strain CFT073; mutS/rpoS, DNA polymorphism in the mutS-rpoS region (EHEC, typical of EHEC group 1; EPEC, typical of EPEC groups 1 and 2; B2, typical of strains from phylogenetic group B2). Genotypes were obtained by PCR; hemolysin, however, was detected by both PCR and hemolysis on sheep blood agar, and adhesins F17 and CS31A were detected by both PCR and sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

g

ND, not determined.
