PRADO, M.R. et al. Identification and antimicrobial susceptibility of bacteria isolated from corneal ulcers of dogs. Arq. Bras. Med. Vet. Zootec. [online]. 2006, vol.58, n.6, pp. 1024-1029. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352006000600008.
A total of 22 clinical specimens were obtained from 19 dogs with corneal ulcer (16 unilateral and three bilateral) for isolation and antimicrobial susceptibility evaluation of the isolated bacteria. Bacterial growth was observed in 100% of the samples (n=22). Staphylococcus intermedius was the predominant species (35.5%), followed by Corynebacterium xerosis (19.3%). Gentamicin, ciprofloxacin, chloramphenicol and tobramycin had a high efficacy against all of the isolated bacteria. The results evidenced that 80.7% of the isolates were Gram positive cocci and Gram positive bacilli, and that those microorganisms were sensitive to gentamicin, ciprofloxacin, chloramphenicol and tobramycin.
