Bacterial infection

Not applicable

In vitro studies identified a short, membrane-disrupting peptide that could help treat bacterial infections. In vitro, the D(KLAKLAK)2 peptide caused lipid bilayer disruption, was active against drug-resistant strains of Gram-negative bacteria and inhibited Pseudomonas aeruginosa biofilm growth with an MIC50 of 600 mg/mL. Next steps include conducting good laboratory practice (GLP) toxicology in rodents and primates and testing in models of severe infections.
