Biological nature of the bacterial pathogenicity phenomenon is based on the interaction of prokaryotic and eukaryotic organisms. The phenomenon is the poly-functional biological potency of germs that are realized by factors (determinants) of pathogenicity. Some fundamental biological functions are responsible for bacterial pathogenicity in a multi-cellular host organism: the adhesive function, the function of invasion and penetration into the cell, the function of evasion of host defense, and the damage function. The action of adhesion, invasion and evasionis directed to towards establishing an ecological niche in multi-cellular host while the aim of the damaging function is destruction of the environment.
