[Effect of intravenous and intragastric feeding on the microflora of the rat intestine].

During intravenous feeding, the contents of the cecum showed a dramatic fall in the amount of anaerobic lactobacilli and the growth of the content of enterobacteria and enterococci. The level of staphylococci and streptococci remained unchanged. These changes did not depend on the presence of fatty component in the nutritive mixture. The switch over of the animals from oral to intragastric feeding did not produce any changes in the microbile profile of the cecum. However, a distinct relationship was noticed between the overall amount of all the representatives of the microflora and the feeding pattern. Apart from an increase in the content of the microorganisms caused by administering a full-value nutritive mixture to the stomach, there was an appreciable rise in the cecum mass.
