Nature: Breastfeeding or helps prevent gastrointestinal infections

Many people worry about the shortcomings of breastfeeding, such as the spread of infectious diseases to babies through breastfeedingBut breastfeeding is now highly recommended, not only for children, mothers, but also for the whole familyIn particular, breast milk has a lot of antibodies, can be a lot of disease resistance, but not easy to get sickIn 2018, a study in the journal Nature focused on "baby gut microbes" and epidemiological evidence suggests that breast milk plays a key role among some gut microbesNow, a new study has added evidence to further investigate the effects of breast milk on the deadly gastrointestinal virus, or to provide new treatment strategies for preventing gastrointestinal diseasesresearchers at the University of Pennsylvania's Perelman School of Medicine recently studied hundreds of babies and found that even small amounts of breast milk can strongly affect the accumulation of viruses in their guts and protect potentially pathogenic virusesThe findings further expand previous studies to show that breastfeeding plays a key role in the interaction between infants and the microbial environmentThe new study may affect strategies to prevent early gastrointestinal diseases and encourage mothers to breast-feed their babies even when they mix it with formulaThe findings were published in the journal NatureResearchers at the University ofused advanced genome sequencing and other methods to measure the number and type of viruses in the first feces (fetal feces) and subsequent feces of newborns in the United States and BotswanaAfter delivery, babies are barely planted, but by a month of life, the population of viruses and bacteria has developed well, reaching a billion in the number of viruses per gram of intestinal contentMost of the first wave of viruses are predators, and they grow in the first bacteria that live in the baby's intestinesAfter four months, viruses that can replicate in human cells and can cause illness are more prominent in infant fecesBreastfeeding has a strong protective effect, inhibiting the accumulation of these potentially pathogenic virusesAnother conclusion of this work is that breast milk can be protective compared to formula-only, even if it is sometimes mixed with formula Dr Frederic Bushman, director of the department of microbiology at the , said the findings could help them better understand why some babies become sick and infected with a deadly infection in the months after birth births of newborns also play a role in the epidemic of viral infections Babies in Botswana are more likely to be infected with potentially harmful viruses during those four months of stool than the faeces of American infants , said lead author Dr Guanxiang Liang, a postdoctoral researcher at the Department of Microbiology, that the geographic location of mothers and babies also appears to have an impact, possibly due to the type and number of microbes that babies come into contact with in the environment Nevertheless, botswana-born babies seem to benefit from breastfeeding, whether exclusively breast-fed or breast-milk mixed formula researchers hope to study people of different ages in the future to understand how the development of the virus (the viral population in the gut) affects children's growth, how virus implantation changes in infants around the world, and how virus implantation affects the outcome of premature birth documents from: Guanxiang Liang, et al.
