Virulence genes and phylogenetic groups of uropathogenic Escherichia coli isolates from patients with urinary tract infection and uninfected control subjects: a case-control study

Table 2 Phylogenetic distribution of uropathogenic and commensal Escherichia coli isolates

Phylogenetic groups (no of isolates)	Prevalence of phylogenetic groups No (%)
	UPEC isolates	Commensal isolates	P value
	N (%)	N (%)
A (26)	17 (12.3)	9 (30)	0.02
B1 (16)	16 (11.7)	0 (0)	…
B2 (85)	76 (55)	9 (30)	0.01
D (41)	29 (21)	12 (40)	0.03
Total	138 (100)	30 (100)

P values (by χ² test or Fisher’s exact test) are shown only if P <0.05. UPEC: Uropathogenic Escherichia coli
