D. discoideum plate killing assay. Each point represents the number of amoebae required to form a plaque on the bacterial lawn of P. aeruginosa PA14 strains after 5 days of incubation. The typA and pscC mutants had a major defect in this virulence model of infection, which was statistically significant as measured with the Mann Whitney test (*** p < 0.001, n = 9).
