Formation of big intestine microecology in healthy newborns in conditions of European North

It has been established that the microecological status of children during the first year of their life was described by immaturity manifesting in presence of dysbiotic interrelations in microbial populations. Microbial flora of the big intestine needed more time for its formation and depended on many factors. At the end of the first year, only 33% of children had intestinal eubiosis. The peak of dysbiotic deviations in the big intestine fell on the 6-month age. As a result of the carried out studies, negative shifts in formation of newborns’ intestinal biocenosis in the conditions of the European North have been detected. Increased periods of making of both the aerobic and anaerobic parts were registered. At the background of the bifidoflora’s deficiency, normal correlations between obligate representatives of the intestinal flora were disturbed, associations of opportunistic microbes appeared. The number of lactose-negative, hemolyzing Escherichias, microbes Proteus, fungi Candida and Staphylococcus aureus increased. But by the end of the neonatal period under affect of breast feeding, microbiocenosis with prevailing of anaerobic microorganisms, narrow spectrum and decreased size of the aerobic association was formed.
