RESUMO

An inhibitor-based characterization system which allowed the identification of beta-lactamases after isoelectric focusing on polyacrylamide gels was developed. This system, using potassium clavulanate and oxacillin, distinguished type I chromosomally mediated enzymes from other beta-lactamases of gram-negative bacteria.
