The intestinal microflora is a positive health asset that crucially influences the normal structural and functional development of the mucosal immune system. In the new born, the colonization of microbes in the alimentary system starts as soon as the womb comes out. A study on the early colonized bacterial species in a new - born will help to understand the immuno protective functions in the newborn. The initial colonization of bacterial population in the alimentary tract of a new-born baby varied according to the mode of child birth. In the alimentary tract of the normally delivered baby, beneficial probiotic microbial invasion in the intestinal region is high and such microbes are mostly from the mother. In a surgically (Caesarian) delivered baby, the alimentary tract receives mostly non beneficial microbes from the environment and hence such babies are susceptible to infection.
