The aim of this study was to investigate the presence of iron-uptake and virulence genes, antibiotic resistance profiles, and phylogenetic relatedness in 115  Escherichia coli  ( E. coli ) strains isolated from broilers in Slovakia and to determine their potential threat to human health. The most frequent phylogroups were B1 (37%) and A (21%), and 33.9% strains were included in pathogenic groups. The commonly observed iron-uptake genes were  feoB  (94%),  sitA  (83%), and  iutA  (58%). Protectins ( iss, kpsMTII ) were identified in 30% of samples. Four percent of B2-associated broilers carried the  papC  (P fimbria) gene connected with upper urinary tract infection. The dominant resistance was to tetracycline (49%), ampicillin (66%), ampicillin + sulbactam (27%), ciprofloxacin (61%), and trimethoprim + sulfonamide (34%); moreover, sporadically occurring resistance to cephalosporins, aminoglycosides, fluoroquinolones, and polypeptide colistin was observed. Genotypic analysis of resistance revealed the presence of  bla CTX-M-1   and  bla CTX-M-2   in two isolates from broilers. Commercial broilers can be reservoirs of virulent and resistant genes as well as  E. coli  causing (extra-)intestinal infections, which can be a potential threat to humans via direct contact and food.
