During the colonization of the oral cavity of disease microorganisms or overgrowth of certain members of normal flora disbiosis is occurred, leading to the postponement of plaque on the teeth (dental plaque, biofilm).The basic microorganisms of dental raid is adhesion on the surface of tooth aerobic and optionally anaerobic microorganisms. Taking into account that adhesion is one of factors of virulence, which pathogenicity and aggressiveness of microorganisms, and, accordingly, weight of gingivitis, depend on, the results of research of adhesion properties of dominant in a dental raid microorganisms are in-process shown at chronic catarrhal gingivitis for dogs.For carrying out a test 4 groups of dogs which after the clinical display of pathological process in gums were divided on were formedcontrol — healthy animals, first  research — with mild chronic catarrhal gingivitis, second middle and third research group — with severe degrees of chronic catarrhal gingivitis. It was established that in the chronic catarrhal gingivitis in dental plaque of dogs significantly higher compared to intact animals is an average adhesion of E. coli and Streptococcus spp. for severe disease and increase with the severity of illness index adhesion coagula negative and coagula positive staphylococci. Compared with healthy animals in dogs at varying severity chronic catarrhal gingivitis it was found a significant increase in the participation rate of erythrocyte adhesion Micrococcus spp., a slight increase in this indicator in coagula negative staphylococci and E. coli, and the gradual reduction in Streptococcus spp. Dogs with chronic catarrhal gingivitis have an index of adhesion of dominant forms of microorganisms, isolated from dental sedimentations grew by comparison to healthy animals and only in Micrococcus of spp. went down on 16.7 %.
