Susceptibility of gram-positive cocci to various antibiotics, including cefotaxime, moxalactam, and N-formimidoyl thienamycin.

The activities of cefotaxime, moxalactam, MK 0787 (N-formimidoyl thienamycin), ampicillin, oxacillin, vancomycin, and clindamycin were compared against gram-positive cocci. MK 0787 was the most active and moxalactam was the least active of these drugs, except against methicillin-resistant Staphylococcus aureus, where vancomycin was most active, and penicillin-resistant pneumococci, where cefotaxime was more active.
