Table 2 Antimicrobial activity penicillin or penicillin plus L.tridentata potentiation/enhancing activity against antibiotic-resistant S. aureus strains.. Bacterial cultures (antibiotic sensitive S. aureus (ATCC 14775), penicillin-resistant S. aureus (ATCC 11632), and multi-drug resistant S. aureus (ATCC BAA-44)) were treated with increasing concentrations of penicillin or penicillin plus ‘β-lactam removed’ L. tridentata extract (*). The MBC was determined at 24 h. Any fold increase in antimicrobial activity between penicillin alone compared to penicillin plus ‘β-lactam removed’ is noted
