Figure 1. PAβN causes loss of periplasmic AmpC β-lactamase to culture supernatants.

Figure 1

Treatment with PAβN reduces intracellular AmpC levels while increasing those in culture supernatants. Representative AmpC β-lactamase immunoblot comparing whole cell lysates and matched supernatants from wild type (PAO1) and AmpC overexpressing (dacB) P. aeruginosa strains treated with or without PAβN.
