A method of increasing the sensitivity of a bacterial strain to a cell-wall active antimicrobial agent, to which the bacterial strain or a progenitor strain from which the bacterial strain has evolved is sensitive is described. The method comprises the step of exposing said bacterial strain to a transforming agent having the following formula (1): where moieties R
