Fig. 1From: Molecular characterization of extended-spectrum β-lactamase-producing Escherichia coli isolated from lower respiratory tract samples between 2002 and 2019 in the Central Slovenia regionDistribution of antibiotic resistance genes and ST131 clonal group among ESBL-EC isolates over an 18-year period. Dashed lines represent the prevalence of blaCTX-M genes from groups 1 and 9, labelled as CTX-M-1 and CTX-M-9, respectively. Dotted lines represent the prevalence of PMQR genes aac(6’)-Ib-cr, qnrA, qnrB, and qnrS. Data for blaTEM and blaSHV are not shownBack to article page
