The indigenous gingival microbiota of dogs is not totally described, although such identification is an important step to establish the etiopathogenesis and adequate therapy for the periodontal disease. The aims of this study were to isolate and identify the periodontal microbiota of German Shepherd dogs from healthy and with periodontal desease sites. Twenty nine German Shepherd dogs from three to six years of age were used in this study. Clinical specimens were analysed from healthy periodontal sites of 12 dogs and sites presenting gingivitis of 17 dogs. A total amount of 672 microbial samples, were isolated where the predominant genera were Pasteurella spp., Staphylococcus spp., Porphyromonas spp. and Fusobacterium spp. The microbiological population of the affected sites was similar to the healthy sites, consisting on an indigenous microbiota. The microbiota on the affecteded sites was higher in number than on the healthy sites, showing change in the environment of the periodontal sites.
