Conflicting needs for a <i>Salmonella</i> hypervirulence gene in host and non‐host environments

1 Aug 2002

Abstract excerpt

The Gram-negative pathogen Salmonella enterica harbours a periplasmic D-Ala-D-Ala dipeptidase (termed PcgL), which confers the ability to grow on D-Ala-D-Ala as sole carbon source. We now demonstrate that inactivation of the pcgL gene renders Salmonella hypervirulent. This phenotype results from the accumulation of peptidoglycan-derived D-Ala-D-Ala in the pcgL mutant and not from an intrinsically faster growth...
