• ex vivo, the corneas from mutant mice showed increased susceptibility to P. aeruginosa adherence at 4.5 h postinoculation with 109 CFU of PAO1 compared to the wild type, with the latter showing little or no attachment; these adhesion differences between mutant and wild-type were no longer apparent at 7.5 hours postinoculation
• mutant mice show a delayed clearance of P. aeruginosa from the ocular surface in vivo; the ocular surfaces of mBD-3-/- mice were colonized by significantly more viable bacteria at both 3 and 6 h postinoculation with 109 CFU of P. aeruginosa (190-fold at 3 h and 32-fold at 6 h; P < 0.03 for both comparisons)
