Abstract
The microflora inhabiting the intestinal mucosa of the pike and the tegument surface of the intestinal parasite Triaenophorus nodulosus is investigated. By means of electron microscopy, the ultrastructural features of bacteria and pattern of their interaction with the colonized surfaces are estimated. Specific distribution of microorganisms belonging to different morphotypes and subdivided into subpopulations on the colonized surfaces is found. Predominance of gram-negative bacteria in all studied microbiocenoses and abundance of nanobacteria in the “superficial” subpopulations are observed. The bacteria of “a deep population” associated with the basal parts of microtrichiae and microvilli are described. It is concluded that the helminthes, the fish parasites possess the normal microflora characterized by specific composition, by ultrastructural features of cells, and by patterns of interaction with the helminth surface. The obtained data characterize the mechanisms of symbiotic interaction of prokaryotes and eukaryotes in the system parasite-host-symbiotic microflora.
