Production of β-lactamases is the most common mechanism by which gram- negative inhibitor-penicillin combinations are in clinical use: ampicillin- sulbactam,
The penicillins, despite their relatively low toxicity for the host, are active against many bacteria, especially gram-positive pathogens (streptococci, staphylococci,
Many penicillins (figure 2) display little activity against Gram negative bacteria, since they do not penetrate the outer membrane.
