Flora bakteryjna pokarmu naturalnego

The human intestinal microflora plays an important role in host metabolism and provides a natural defense mechanism against invading pathogens. At birth the neonatal intestinal tract is virtually sterile. The establishment of a normal bacterial flora depends on compound of mother's milk. Mother milk possesses the unique immunologic and nutritional benefits. It consists of many bioactive factors which influenced neonatal intestinal ecosystem in the first day of life. Sterile mother milk after delivery is very soon a seat of “positive” bacteria as well as includes fewer species pathogenic bacteria. In healthy breastfeeding infants born by vaginal delivery. Bifidobacterium and Lactobacillus are predominant in neonatal feces. In preterm infants the delay in normal colonization with lactobacilli and bifidobacteria is observed. Bacteria present in mother's milk are from different sources. May have an endogenous origin as well as may be the result of contamination from surrounding breast skin. Lactic acid bacteria are isolated from mammary areola, breast skin, oral swabs The intestinal microflora of the newborns could be influenced by the mode of delivery, maternal cervix and vaginal colonization, mother's diet, antibiotics etc.
