PBP4-mediated beta-lactam resistance among clinical strains of Staphylococcus aureus. J.Antimicrob.Chemother., 76:2268-2272, 2021 Cited by PubMed Abstract: PBP4, a low-molecular-weight PBP in Staphylococcus aureus, is not considered to be a classical mediator of β-lactam resistance. Previous studies carried out by our group with laboratory strains of S. aureus demonstrated the ability of PBP4 to produce β-lactam resistance through mutations associated with the pbp4 promoter and/or gene. Recent studies of β-lactam-resistant clinical isolates of S. aureus have reported similar mutations associated with pbp4.
