When challenged with the wild-type strains (ATCC 17978, PAO1 or 132), survival rates were 100% for vaccinated versus 0% for control mice (Figs 6b,7band 8c); and when α-Pa vaccine was administered intramuscular, survival was 100% for vaccinated versus 25% for control mice, after PAO1 infection (Fig. 7c). The gene discussed is ENPEP; the disease is infection.
