Combined therapeutic option for NDM-producing Serratia Marcescens - an in vitro study from clinical samples.

Background: Treating NDM-producing bacteria poses a significant challenge, especially for those bacteria inherently resistant to polymyxin, such as Serratia marcescens, necessitating combined therapies.

Objective: To assess in vitro the synergistic effect of different antimicrobial combinations against NDM-producing S. marcescens.
