Plain-English summary
A group of cats with infected corneal ulcers, which caused symptoms like eye discharge and discomfort, were tested for bacterial infections. Out of 92 cats, bacteria were found in 54 eyes, with Staphylococcus being the most common type. The study found that ciprofloxacin and gentamicin were the most effective antibiotics for treating these infections, while some bacteria showed resistance to other antibiotics like erythromycin. With the right treatment, many of these cats can recover from their eye infections.

Abstract
OBJECTIVES: To assess the antibiotic susceptibility of bacteria isolated from corneal ulcers in cats. METHODS: A total of 92 cats with infected corneal ulcers were swabbed for bacterial culture and the antibiotic sensitivity of the isolates analysed. RESULTS: Bacteria were isolated from 54 of 92 infected eyes with corneal ulcers and purulent discharge. A total of 59 bacterial isolates were obtained from the 54 ulcers. The ratio of Gram-positive to Gram-negative isolates was approximately 3:1. The most commonly isolated Gram-positive bacteria were Staphylococcus species (51 per cent of all isolates), while Pseudomonas aeruginosa (13.5 per cent of all isolates) was the most common Gram-negative bacteria isolated. The Gram-negative isolates demonstrated a greater incidence of antibiotic resistance than the Gram-positive ones. The most effective antibiotics against the isolates were ciprofloxacin, tobramycin and gentamicin, with erythromycin and lincomycin showing the greatest number of resistant isolates. CLINICAL SIGNIFICANCE: Staphylococcus and Pseudomonas species were the most common Gram-positive and Gram-negative bacteria, respectively, isolated from feline eyes with ulcerative keratitis. The second-generation fluoroquinolone, ciprofloxacin and the aminoglycoside gentamicin were found to be highly effective against the majority of isolates.
