Isolation of multiresistant staphylococci from canine otitis and its importance for public health
Keywords:
zoonosis, antimicrobial resistance, StaphylococcusAbstract
The occurrence of Staphylococcus as etiologic agent of canine otitis was studied in the city of Aracaju,
Sergipe. Fifty-five swab samples where obtained from private veterinary clinics and analyzed for the
presence of Staphylococcus sp. The traditional method was used and Staphylococcus was isolated
from 18 (32,7%) of the 55 samples collected. The species isolated were S. intermedius, S. aureus and
S. schleiferi. Antimicrobial susceptibility was also tested using the agar diffusion method. This
opportunistic pathogen was more susceptible to cephalexin, imipenem, amoxycillin – clavulanic acid,
teicoplanin and vancomycin, and more resistant to clindamycin, azithromycin, neomycin and
trimethoprim-sulpha. At least, 83% of the isolates were resistant to one antimicrobial compound. The
isolation of oxacillin – resistant Staphylococcus (17% of the isolates) is a fact that worries public health
authorities, showing that pet animals can be a potential source for humans of antimicrobial-resistant
pathogens.
