title: In vitro activity of BMY-28100, a new oral cephalosporin.
abstract: The activity of BMY-28100, a new orally administered cephalosporin, was compared with those of cephalexin and cefaclor. BMY-28100 was the most active drug against Staphylococcus aureus (MIC for 90% of strains tested [MIC90], 1.0 microgram/ml), streptococci (MIC90S, less than or equal to 0.125 microgram/ml), and Klebsiella pneumoniae (MIC90, 2 micrograms/ml). The drug was active against Haemophilus influenzae and gonococci but not against other organisms generally resistant to cephem antibiotics.
