Identification and antimicrobial susceptibility patterns of Staphylococcus spp. isolated from canine chronic otitis externa
Swab samples obtained from 96 dogs with chronic otitis externa were cultured for the isolation of Staphylococcus species. Of 57 staphylococcal strains, 41 (72%) were coagulase-negative (CNS). The identification of staphylococci strains was made by standard procedures for the routine identification of staphylococci in clinical practice. S. sciuri was the most frequent species isolated (22.8%) from chronic otitis externa in dogs followed by S. intermedius (12.3%), S. auricularis (10.5%) and S. aureus (8.8%). Three (5.2%) CNS strains could not be identified. Bacterial isolates were susceptible to enrofloxacin, gentamicin, cephalothin, chloramphenicol and neomycin. Resistance was most common to penicillin G, oxacillin and ampicillin.
