ABSTRACT

Objective: To know the in vitro susceptibility to netilmicin, gentamicin, tobramycin, amikacin, ciprofloxacin, ofloxacin, moxifloxacin and gatifloxacin in 400 strains isolated from ocular infections in a statistical comparative study.
Material and methods: In a retrospective, comparative and lineal study we made susceptibility test by Kirby and Bauer diffusion technique to 400 Gram positive and Gram negative ocular bacterial isolates, the ocular sources were 171 bacterial keratitis, 148 conjunctivitis, 27 endophthalmitis, and 54 other ocular infections.
Results: The bacterial isolates were 254 Gram positive and 146 Gram negative bacterial strains, 81 Staphylococcus epidermidis, 76 Staphylococcus aureus, 57 Streptococcus , 25 Bacillus, 16 Corynebacterium and Actinomyces, 58 Enterobacteriaceae, 50 Pseudomonas, 17 Haemophilus influenzae and 5 Neisseria. Statistic study by logistic regret ion method was applied.
Conclusions: The susceptibility to netilmicin of Staphylococcus coagulase negative was higher than gatifloxacin and moxifloxacin, equal to gatifloxacin for Gram negative and positive bacteria and better than tobramycin in both mayor bacterial group studied.
