S. typhimurium metabolism during infection. (A) Functional Classification of metabolic gene subsets analyzed for expression in macrophage 24 hr post infection. (B) Subset of metabolic genes up-regulated in S. typhimurum 24 hr after infection of macrophage cell lines (RAW 246.7). Genes implicated in energy metabolism, heme and aromatic amino acid are most up-regulated.
