Table 2 Genotypic characterization of sequenced ESBL-E. coli isolates; presence of a certain factor is based on the results from ABRicate [ABRicate v. 1.0.0 (https://github.com/tseemann/abricate), databases used: VFDB, ResFinder, PlasmidFinder, BacMet, ARG-ANNOT, and Ecoli_VF] using de novo-assembled sequences and is depicted in black. Detected genes are assigned to the following categories: 1β-lactam antibiotics, 2quinolone, 3multidrug resistance translocators, 4phenicol antibiotics, 5aminoglycosides, 6tetracycline antibiotics, 7sulfonamides and trimethoprim, and 8macrolide, lincosamide, and streptogramin B.
