The Pathogenic Microflora and Microbial Interactions in Oral Cavity in Dogs

The existing microorganisms in the oral cavity are not harmless and they can express various pathogenic factors. These pathogenic factors are represented by the morphostructural and functional characteristics that ensure germ aggression against the host. They are represented by a particular chemical structure of the germs, different morphological characteristics, or different functional properties caused by certain enzymes or toxic discharge. The expression of pathogenicity of microorganisms is achieved when there is an imbalance that can affect the dynamics of the relations between macro and micro-organisms, the interaction of host antimicrobial capacities and pathogenic proprieties of microorganisms in favor of the latter. Depending on their pathogenic proprieties these bacteria can be: pathogenic, moderately pathogenic, highly pathogenic. The objective of this study is to reveal the pathogenic proprieties and the interactions of the oral cavity bacteria.
