Figure Lengend Snippet: Tolerability and behavioral impact of cefiderocol treatment. A, B , Toxicity scores (max 10 for conjunctival, 16 for corneal) of New Zealand White (NZW) rabbits exposed to topical drops of cefiderocol. Medians and interquartile ranges are shown, n = 6. No statistical differences were found between groups. C , Behavioral signs of NZW rabbits exposed to cefiderocol topical drops. Medians and interquartile ranges are shown, n = 39. Asterisks indicate significant differences from saline group by Kruskal–Wallis with Dunn’s post-test, P < 0.001.

Figure Lengend Snippet: Efficacy of antibacterial treatment. A, B , The colony-forming units (CFU) per cornea were determined by dilution plating. The onset group was evaluated at 16 hours postinfection, and before treatment. The other groups had 16 hours of untreated infection, followed by 8 hours of treatment as indicated. Asterisks indicated significant differences from the saline group by analysis of variance (ANOVA) with Tukey’s post-test. The pistachio lines represent a 99% and the red lines a 99.9% reduction in CFU compared with the onset. n = 6 except for onset group n ≥ 3. C, D , Images of eyes were taken before euthanasia from a fixed distance. The onset group was imaged at 16 hours postinfection, and before treatment. The other groups had 16 hours of untreated infection, followed by 8 hours of treatment as indicated. Relative infiltrate area was determined using ImageJ software. Mean and SD are shown and were compared by ANOVA and Tukey’s post-test. ∗ P < 0.05; ∗∗ P < 0.01; ∗∗∗ P < 0.001; ∗∗∗∗ P < 0.0001. Panels A, C used strain K900, and panels B, D used strain CDC1270. CEF = cefiderocol; CIP = ciprofloxacin; TOB = tobramycin; XDR = extensively drug-resistant.
