IntroductionCorticosteroid-antibiotic combinations are commonly used in veterinary ophthalmic practice, yet the potential for corticosteroids to modulate antimicrobial susceptibility remains incompletely characterized. This study evaluated the in vitro effects of fluorometholone (FML) on the antimicrobial susceptibility of three major canine ocular pathogens—Staphylococcus pseudintermedius, Streptococcus canis, and Pseudomonas aeruginosa—and compared its interaction profile with that of dexameth
