New targets for the mechanism of action of antibiotics active against gram-positive cocci.


The main mechanisms of resistance to beta-lactams in gram-positive cocci include either the production of beta-lactamases or alterations in the molecular targets of these antibiotics, the penicillin binding proteins (PBPs). In spite of the appearance of new beta-lactams, more stable to the hydrolytic activity of beta-lactamases or with higher affinity for… (More)
