Common and specific genomic sequences of avian and human extraintestinal pathogenic Escherichia coli as determined by genomic subtractive hybridization

Table 2 Phylogenetic groups of the E. coli isolates used in the SF distribution study

	Number of isolates in each phylogenetic group (%)^B
Category of E. coli^A	A	B1	B2	D
APEC	36 (37.89)	11 (11.58)	22 (23.16)	26 (27.37)
UPEC	10 (10.53)	6 (6.32)	61 (64.21)	18 (18.94)

^AEach category of E. coli contains 95 isolates. APEC, Avian Pathogenic Escherichia coli; UPEC, Uropathogenic Escherichia coli.
^BPercentages of isolates falling within each phylogenetic group are shown in parentheses. E. coli isolates in phylogenetic groups B2 and D are more likely to be associated with disease than phylogenetic groups A and B1 [34].
