Checkerboard testing method indicates synergic effect of pelgipeptins against multidrug resistant Klebsiella pneumoniae

Abstract

Multidrug resistant bacteria infections have motivated the search for new therapeutics. The synergic effect of conventional antibiotics and lipopeptides of the pelgipeptin family was evaluated by the Checkerboard method. Results indicate that the association of Pelgipeptin B and C or chloramphenicol has a synergic effect against a multidrug resistant bacteria strain; which may be may be due to the variations on hydrophobicity and mechanisms of action of the molecules tested.
