Attenuation of Salmonella enterica Serovar Typhimurium by altering biological functions of murein lipoprotein and lipopolysaccharide

Infect Immun. 2005 Dec;73(12):8433-6. doi: 10.1128/IAI.73.12.8433-8436.2005.

Abstract

We constructed Salmonella enterica serovar Typhimurium double-knockout mutants in which either the lipoprotein A (lppA) or the lipoprotein B (lppB) gene was deleted from an msbB-negative background strain by marker exchange mutagenesis. These mutants were highly attenuated when tested with in vitro and in vivo models of Salmonella pathogenesis.
