FIG 2.
Cell-associated hemolytic activity of fluorescent pseudomonads strains harboring T3SS genes. Cell-associated hemolytic activity was measured as described in Materials and Methods. Results are mean values from at least three independent experiments. Standard deviations are shown. Red blood cells were incubated 1 h at 37°C with bacteria grown at 25 or 37°C (multiplicity of infection, 1). nd, not determined (strains did not grow at 37°C).
