ABSTRACT
Morphofunctional equivalents of the process of long-term intracellular prokaryotes--eukaryotes interaction were studied by light and electron microscopy. The mechanisms for adaptation, elaborated in the course of evolution of bacteria-host interaction, were analysed on the ultrastructural level. A concept on the role of hypothalamic nonapeptides, as factors of regulation of intracellular persistence and symbiosis of prokaryotes, is discussed.

The paper presents the results of light, atomic-force, and electron microscopic studies of prokaryotes (various Staphylococcus aureus strains) and eukaryotes (Rat digestive and respiratory cells and tissues) in in vivo and in vivo interactions. It is concluded that hypothalamic nonapeptides play a modulating role in the persistence and symbiotic relations in the bacterium-host system and regulate cellular and tissue homeostasis through reparative histogenesis.
