Salmonella utilizes L-arabinose to silence virulence gene expression for accelerated pathogen growth within the host

Abstract excerpt

Carbon source is an important nutrient for bacteria to sustain growth and often acts as a signal that modulates virulence expression. L-arabinose is produced by plants and plays an important role in regulating the global gene expression of bacteria. Previously, we have shown that L-arabinose induces a more severe systemic infection in Salmonella-infected mice with normal microbiota, but does not affect the...
