RESUMO
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 role of hypothalamic nonapeptides in the interaction of prokaryotic and eukaryotic cells was studied in the experimental setting. Nonapeptides were found to stimulate the adaptive and regenerative properties of eukaryotic cells and they are likely to have an antimicrobic effect on prokaryotic ones. The paper discusses the modulating role of nonapeptides in the establishment of symbiotic relations in the bacterial agent-host system.
