beta-lactam antibiotic-resistant Staphylococcus aureus
beta-lactam antibiotic-resistant Staphylococcus aureusA term of little recent use referring to the mechanism of antibiotic resistance—production of beta-lactamase by Staphylococcus spp—rather than to the antibiotic (methicillin) in which this resistance was first recognised. Bacteria resistant to meticillin are often also resistant to nafcillin and oxacillin, and respond poorly to cephalosporins.
