(A) Quantitation of viable bacteria detected at 5 days p.i. from corneas of PBS-, Tβ4-, ciprofloxacin-, and Tβ4 + ciprofloxacin-treated animals. Results are reported as CFU/cornea ± SD. (B) PMN numbers as correlated from levels of MPO detected from corneal lysates after infection. Results are reported as log₁₀ PMNs/cornea ± SD. (C), ROS levels determined by fluorescent values (DCFH-DA values—negative control values). Fluorescent values were acquired by subtraction of negative control values from DCFH-DA values. Results are reported as mean intensity ± SD. (D) Nitrite levels as measured from corneal lysates after infection. Results are reported as μM nitrite/cornea ± SD. N = 5 corneas/group/time point. ^# P < 0.05 versus PBS; ^! P < 0.05 versus ciprofloxacin.
