The evidence related to the difference in gut bacteria in children born by Ceasarean delivery (surgical C-section i.e. without passing through the birth canal) compare to the children born by normal vaginal delivery. Whether C-section delivery makes the children more prone to some diseases comare to the children by vaginal delivery.
Introduction:
There is a dramatic change in gut bacteria during human pregnency which help a pregnant woman to adapt under the stress condition related to carrying a fetus. The microbial community plays an important role in performing specific functions. The intestinal microbiota is essential for the development of the immune system and possible pathogenesis of several allergic and autoimmune diseases. The infants born vaginally are exposed to a group of beneficial microorganism known as microbiota, when passes through the birth canal. This exposure of the baby to the mother's vaginal microbes passes the mother's flora to the baby which is important in the post natal development of the immune system of the baby.
Explanation of Solution
Microbial ecology of the gastrointestinal tract and the mucosal immune system are related to each other. The early development of the intestinal microbiota in relation to the developing immune system and the early influence of caesarean versus vaginal delivery (VD) is a matter of concern always, as infants after a caesarean delivery, have been associated with increased risks of asthma, allergies, obesity, and immune deficiencies. In the process of C-section infant won't come into contact with maternal vaginal fluid or microflora, instead exposed with skin microbes which are a very different set of bacterial species. Nevertheless, there is a number of evidence which shows that intestinal bacteria play an important role in the postnatal development of the immune system. This intestinal flora development varies based on the mode of delivery. The available epidemiological data indicates that atopic diseases appear more often in infants born after caesarean delivery than after vaginal delivery. The exposure during the vaginal delivery makes the infant's more access to the mother's microbiota, which enters in the intestine during the travel of baby through the birth canal.
Malamitsi-Puchner et al. proposed that only vaginal delivery promotes the production of several cytokines implicated in neonatal immunity. Hallstrom et al. found a connection between caesarean delivery, disturbed intestinal colonization and probable occurrence of necrotizing enterocolitis (NEC) in preterm infants. Several other epidemiological data demonstrates that caesarean delivery imparts an increased risk for allergic diseases in later childhood.
Thus it is concluded that a number of evidence supports the fact related to the difference in gut bacteria in children born by Ceasarean delivery compare to the children born by normal vaginal delivery. C-section delivery makes the children more prone to some diseases like asthma, allergies, obesity, and immune deficiencies comare to the children born by vaginal delivery.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forward
