Abstract

We have examined 96 conditionally healthy primigravidae and 96 newborns. Group 1 (n = 51): gravidae with normal course of preg-nancy and delivery, group 2 (n = 45): gravidae with normal course of pregnancy and deliveries by caesarian section (indications for the operation - severe myopia), group 3 (n = 51): newborns from gravidae of group 1, group 4 (n = 45): newborns from gravidae of group 2. Purpose: study of the development of microbiota in the large intestine of newborns depending on various delivery methods. Enterococcus sp. (58,2 %), S. epidermidis (55,7 %), Corynebacterium sp. (53,1 %), E. coli (41,7 %) dominated in meconium microbiota. By the day 5 in group 3 we registered more frequently (p < 0,05) Bifidobacterium sp., Corynebacterium sp., E. coli, in group 4 - Klebsiella sp. Independently from the delivery method, by day 5 we observed in the feces of newborns increased (р < 0,5) content of Bifidobacterium sp., Lactobacillus sp., E. coli, Enterococcus sp., and S. aureus.
