Route of Injection Affects the Impact of InlB Internalin Domain Variants on Severity of Listeria monocytogenes Infection in Mice

Figure 2

Impact of id InlB variants on severity of intraperitoneal infection in BALB/c mice. Results are shown as a relative increase of bacterial loads in the liver and spleen for the recombinant and wild-type strains comparatively with the strain EGDeΔinlB which lacked the inlB gene. The strains are designated as follows. EGDeΔinlB::InlB1, idInlB1; EGDeΔinlB::InlB9, idInlB9; EGDeΔinlB::InlB14, idInlB14; and EGDe, wild-type strain EGDe.
