Characterization of the main Escherichia coli B2 phylogroup clones, by combination of subgroup and O-type, among patients with extraintestinal infections, France, 2012–2014*

Subgroup and O-type B2 clones, no. (%), n = 155
I-O25b 15 (62.5)
I-O6a 2 (8.3)
I-O16 3 (12.5)
II-O22 2 (5)
II-O2b 4 (10)
II-O6a 26 (65)
III-O6a 16 (100)
IV-O2b 19 (95)
VI-O4 13 (92.9)
VII-O18 2 (66.6)
VII-O75 1 (33.3)
IX-O1 7 (50)
IX-O18 3 (21.4)
IX-O2a 3 (21.4)

*Data are presented as no. (%) of each clone within the corresponding subgroup. Roman numerals correspond to the B2 subgroup. The correspondence with the Achtman multilocus sequence type schema is as follows: subgroup I, sequence type complex (STc) 131; subgroup II, STc73; subgroup III, STc127; subgroup IV, STc141; subgroup VI, STc12; subgroup VII, STc14; subgroup IX, STc95 (22). The most anticipated serotypes in extraintestinal infections were searched by PCR: O1, O2a, O2b, O4, O6, O7, O12, O15, O16, O17, O18, O22, O25a, O25b, O45a, O75, O78.
