[State of intestinal microbiocenosis and its correction in pregnancy women living under conditions of increased radiation pollution].

The contents of the large intestine were investigated bacteriologically in 44 pregnant women at the pregnancy term of 27-28 weeks living in the areas contaminated with radionuclides at a concentration of 15-40 C/km2. It was found that in 9.6 per cent of the women the intestinal microbiocenosis was within the normal and in 19.1 per cent there was detected marked dysbacteriosis. In the other women compensated or subcompensated intestinal dysbacteriosis was recorded. The state of the large intestine microbiocenosis in the pregnant women did not depend on urogynecological or infectious diseases in the case histories. The prophylactic treatment with eubiotics (bifidumbacterin per rectum and lactobacterin intravaginally) aimed at the correction of the impaired microbiocenosis had a favourable effect which did not depend on urogynecological or infectious diseases in the case histories. After the completion of the prophylaxis course with the eubiotics some indices improved but the percentage of the pregnant women isolating colibacilli with the properties of virulence increased.
