FIG. 1.

Corneal MRSA colony counts after treatment. This figure presents the median number of MRSA corneal colony counts [Log₁₀ (Colony Forming Units (CFU) + 1)/mL] for each treatment group (n = 8 per group) in eyes with abraded and intact corneal epithelium. Both 0.5% tigecycline and 50 mg/mL vancomycin demonstrated significantly fewer MRSA corneal colony counts compared with the saline controls (P ≤ 0.05 KW) in eyes both with abraded and intact corneal epithelium. Tigecycline and vancomycin produced >3 Log₁₀ (>99.9%) bactericidal decreases in colony counts in eyes with both abraded and intact corneal epithelium compared with the baseline no treatment controls (baseline). MRSA, methicillin-resistant Staphylococcus aureus.
