Figure 7From: Acid shock of Listeria monocytogenes at low environmental temperatures induces prfA, epithelial cell invasion, and lethality towards Caenorhabditis elegansNematode infection assays. Death curves of nematodes fed with acid-shocked L. monocytogenes (â—Š) and unshocked control cells (â– ). Surviving worms were transferred daily to freshly prepared acid-shocked or unshocked L. monocytogenes for up to 14 d. The error bars are from four independent experiments using 20 worms in each condition, totaling 160 worms.Back to article page
