Interspecies Communication and Periodontal Disease

Table 1

Describing the various benefits of interspecies communications in biofilms.

Communication
Increase chances of survivalProtection from environment

(i) Primary colonisers provide site for the adherence of the secondary colonisers.
(ii) Coaggregation bridge allows anaerobes to come together and interact which normally do not coaggregate.
(iii) Metabolic interactions
which makes the biofilm environment favourable for the survival of bacterial species.
(iv) Signaling molecules to regulate cell behavior in response to environmental changes.
(v) Genetic exchange increases the pathogenicity of microbes.
(i) Extracellular polymorphic substance restricts the diffusion of antimicrobials from the surrounding environment.
(ii) Horizontal gene transfer which provides antibiotic resistance.
