[Ultrastructural changes in rectal mucosa cells in experimental Escherichia infection]

Ultrastructural changes of rectum epitheliocytes and cells of lamina propria were studied at the period from 15 minutes to 2 days after inoculation using the model of experimental escherichiosis. The results obtained allow to determine the correlation of ultrastructural changes and the data of morphometric analysis. Ultrastructural peculiarities were determined of the rectum cells and the different cell populations were studied during infection's process.
