A microbiome is the entirety of the microbial life that is a part of the ecological communities comprising all complex creatures. For example, the bacterial colonization of the intestine that begins at birth is a process of considerable interest to science and medicine. Numerous studies have shown that there are differences between the gut microbiota of babies born transvaginally and are therefore exposed to maternal vaginal bacteria compared with those born via Caesarean section. In the latter instance, neonate gut microbiota bacteria is less diverse during the first months of life. Now, a new study has analysed the evolution of the gut microbiota of low-birth weight infants and premature babies. This research has identified that immediately after birth the mouth microbiota is similar to that of the gut in these babies, but that it differs substantially after three weeks of life. The study, published in the latest edition of the American Academy of Microbiology journal ‘mBio’, is the first to analyse the time dependent differentiation of the exact composition of the microbiota in varying body sites of newborn infants. http://mbio.asm.org/content/4/6/e00782-13 Important implications include the differing susceptibility of low birth weight newborns to necrotizing enterocolitis compared to normal birth weight newborns.
