The extracts, when associated with gentamicin and\u0000amoxicillin, showed synergism against all standard and multiresistant strains, with the exception\u0000of Klebsiella pneumoniae carbapenemase and Klebsiella pneumoniae producing extendedspectrum\u0000β-lactamase, respectively. When combined with amikacin, they also demonstrated synergism\u0000against multidrug-resistant strains; however, only the ethyl acetate extract had a synergistic\u0000effect against E. coli ATCC 25922. The association of penicillin with methanolic extract\u0000showed synergism only for Klebsiella pneumoniae producing extended-spectrum β-lactamase and\u0000S. aureus ATCC 29213, while the ethyl acetate extracts demonstrated synergism against S. aureus\u0000and Klebsiella pneumoniae producing extended-spectrum β-lactamase.\u0000\u0000\u0000\u0000It was found that C. quercifolius extracts have antibacterial potential against gramnegative\u0000bacteria. However, the need for additional research using specific methods against bacteria\u0000carrying different resistance mechanisms, especially gram-positive ones, is highlighted, with\u0000the aim of elucidating their mechanism of action.\u0000\u0000\u0000\u0000The species was found to have substances with potential against Gram-negative bacteria.
