Methods: Enterococci isolated from diabetic-foot infections were identified, evaluated by macrorestriction analysis, and screened for virulence traits and antimicrobial resistance. Results: All isolates were considered multidrug-resistant, cytolysin and gelatinase producers, and the majority also demonstrated the ability to produce biofilms. Conclusions: These results indicate the importance of enterococci in diabetic-foot infection development and persistence, especially regarding their biofilm-forming ability and resistance to clinically relevant antibiotics.engDiabetic foot infectionsEnterococcusMulti-drug-resistant (MDR)Virulence factorsBiofilmsjournal article10.1016/j.eimc.2015.01.007
