Figure 5. TnPZs can contribute to fitness in mice.

Figure 5

Animals were infected with 1∶1 mixtures of mutant and isogenic wild type strains, sacrificed two weeks later, and scored for abundance of each strain type by tests of individual colonies for susceptibility/resistance phenotypes. Black circles represent mixed infection with PeCan18B wild type and PeCan18B ΔTnPZ(cat); white circles represent mixed infection with PeCan18B wild type and PeCan18B Δtfs3(kan); black triangles represent mixed infection with HUP-B43 wild type and HUP-B43 ΔTnPZ(cat). Each dot represents H. pylori types (fraction of mutant relative to wild type) recovered from a single mouse.
