NEGRO, V.B. et al. Subgingival bacterias encountered in dogs suffering spontaneous periodontal disease and susceptibility to antimicrobials. First report in Republica Argentina. InVet [online]. 2012, vol.14, n.2, pp.141-149. ISSN 1668-3498.

Although the subgingival microbiota on periodontal disease in the dog, has been studied, there are only abroad reports. In the knowledge of the authors none research of this type was carried out in our country. Because of that it was decided to study the subgingival microbiota and its susceptibility to antimicrobial drugs in dogs, suffering of spontaneously occurring periodontal disease that should be treated in the Surgical Service, Veterinary Medicine Teaching Hospital and in the Dental Service, Faculty of Veterinary Sciences, UBA. A total of 54 sites from 18 dogs were sampled subgingivaly with a Gracey curet, determining previously the periodontal status by means of a dental probe. A total of 105 microorganisms were isolated (79 aerobes and facultaty anaerobes and 28 strict anaerobes). Strict anaerobic bacterias were isolated more often in those sites with deeper periodontal pockets (greater than 4 mm). Susceptibility of antimicrobial was determined according to the Clinical and Laboratory Standards Institute (CLSI). None of the isolate microorganisms exhibited resistance to amoxicilin/acid clavulanic, gentamicine, vancomicine, clindamicin neither or metronidazol. The results obtained will be of great utility in the treatment of the affected dogs upon not being available data of this type in our country.
