Non-invasive Salmonella typhimurium mutants are avirulent because of an inability to enter and destroy M cells of ileal Peyer's patches.

Molecular microbiology - 1 May 1997

Abstract excerpt

Salmonella typhimurium initiates infection of a host by invading M cells of Peyer's patches within the small intestine. The ability of the bacteria to invade mammalian cells has been shown to be regulated by environmental conditions, including oxygen concentrations, osmolarity, and growth phase. We have previously created oxygen-regulated Tn5lacZY S. typhimurium mutants that are defective in invasion. We have now...
