We investigated the combination effect of teicoplanin (TEIC) or vancomycin (VCM) and 6 β-lactams in vitro using 49 strains of methicillin-resistant Staphylococcus aureus (MRSA) isolated from neonates who were admitted to the newborn intensive care unit. We combined TEIC with imipenem (IPM), meropenem (MEPM), panipenem (PAPM), cefpirome (CPR), flomoxef (FMOX), or sulbactam (SBT)/ampicillin (ABPC). Synergistic effects were noted in 16 to 48 strains. In particular, the combinations of TEIC and IPM, MEPM, PAPM, or FMOX showed synergistic effects in many strains. Furthermore, 3 strains did not respond to the combination of TEIC and CPR; however, none of the strains exhibited antagonism. Combination with VCM and the above β-lactams produced synergistic effects in 1 to 32 strains. No changes were seen in 1 to 17 strains, and 2 to 6 strains exhibited antagonism. These results suggest that, when combined with the β-lactams tested, TEIC exhibits more potent synergistic effects than VCM.
