Figure. Graphic representation of the results of the factorial analysis of correspondence carried out with whole data from the 129 Escherichia coli strains. A) Projections of the variables on the F1/F2 plane: phylogenetic group and subgroups (A0, A1, B1, B22, B23, D1, and D2), type of extended-spectrum β-lactamase (ESBL) (TEM, SHV, CTX-M), virulence factors (pap, sfa, hly, aer), and the source infection (inf) or colonization (col). B) Projections of the variables on the F1/F2 plane: phylogenetic group and subgroups (A0, A1, B1, B22, B23, D1, and D2), type of ESBL (TEM, SHV, CTX-M), and ciprofloxacin resistance (cipR) or the ciprofloxacin susceptibility (cipS).
