A macrophage-based screen identifies antibacterial compounds selective for intracellular Salmonella Typhimurium

Abstract

Salmonella Typhimurium replicates within host phagocytes. Here, the authors show that a known psychoactive drug (metergoline) inhibits growth of the pathogen in macrophages, disrupts the proton motive force at the bacterial cytoplasmic membrane, and extends animal survival during systemic infection.
