Table 2. Frequency of major human associated E. coli sequence types (STs) with respect to either the number of phylogroup D isolates (ST69), the number of B2 isolates (STs 73, 95, 127, 131) or the total number of E. coli isolates recovered from the host group.

Phylogroup	ST	Cat (n)	% of D or B2 isolates	% of E. coli isolates	Dog (n)	% of D or B2 isolates	% of E. coli isolates
D	69	8	33.3	2.4	2	15.4	1.0
B2	73	64	46.4	19.1	8	15.4	3.9
B2	95	24	17.4	6.9	4	7.7	2.0
B2	127	6	4.3	1.8	5	9.6	2.5
B2	131	1	0.7	0.3	2	3.8	1.0

ST, sequence type; n, number of samples.
