ResumoSeven types of β-lactamases distinguished by analytic isoelectric focusing have been found on 24 Pseudomonas plasmids belonging to at least eight incompatibility groups. TEM-1- and TEM-2-type enzymes that are determined by transposable genetic elements are distributed among five different incompatibility groups. The other β-lactamase types are found on plasmids in single incompatibility groups. β-Lactamases unique to Pseudomonas plasmids occur on plasmids not transmissible to enterobacteria by conjugation.
