Visual quantification of invaded host cell death up to 20 h post-infection confirmed that corneal epithelial cells containing intracellular PAO1 survived significantly longer than PAO1ΔexoSTY: median with inter-quartile range (IQR) time of cell death for PAO1ΔexoSTY was 5.2 ± 1.4 h which extended to 9.5 ± 1.3 h for PAO1 (Fig 1B). The gene discussed is SMOX; the disease is infection.
