title: [Food specialization in ruminants: the role of endosymbiosis in its formation].
abstract: Peculiarities of endosymbiosis have been studied in four species of ruminant animals with different food specialization (Cervus elaphus, Moschus moschiferus, Carpa sibirica, ans Gasella subgutturosa) using the methods of macromorphology, light and electron microscopy, and histochemistry. The differences in morphology of bacteria from populations inhabiting rumen epithelium of the studied animals have been revealed. The specificity of connection of bacteria with cornified epithelium has been demonstrated. This connection is reflected on the structure of outer epithelium layers. The functional interpretation of gizzard epithelium macrolandscape peculiarities has been improved. An important part of endosymbiosis in evolutionary-morphological transformations of stomach and intestines, and in formation of food specialization in wild animal species has been underlined.
