Initial Acquisition Of Microbiota
The initial acquisition of microbiota is the formation of an organism‘s microbiota immediately before and after birth. The microbiota are all the microorganisms including bacteria, archaea and fungi that colonize the organism. The microbiome is another term for microbiota or can refer to the collected genomes.
Many of these microorganisms interact with the host in ways that are beneficial and often play an integral role in processes like digestion and immunity. The microbiome is dynamic: it varies between individuals, over time, and can influenced by both endogenous and exogenous forces.
Abundant research in invertebrates has shown that endosymbionts may be transmitted vertically to oocytes or externally transmitted during oviposition. Research on the acquisition of microbial communities in vertebrates is relatively sparse, but also suggests that vertical transmission may occur.
Tips To Boost Your Gut Microbiome
Your gut microbiome is a vast community of trillions of bacteria and fungi that inhabit every nook and cranny of your gastrointestinal tract, and have a major influence on your metabolism, body weight, propensity to illness, immune system, appetite and mood. These microbes mostly live in your lower intestine and outnumber all the other cells in your body put together.
Conceptually, we should view these microbes as a newly discovered organ, weighing slightly more than our brains and nearly as vital. There are some organs we can live without, including our spleen, gall bladder, tonsils and appendix, but we wouldnt survive long without our gut microbes. Intriguingly, no two microbiomes are the same we are all unique. And more than ever, were finding out just how important these microbes are.

According to research, the richer and more diverse the community of gut microbes are, the lower your risk of disease and allergies. This has been shown in animal tests and also in human studies comparing the microbes of people with and without particular diseases. Examples from recent work at Kings College London include studies of diabetes, obesity, allergy and inflammatory diseases like colitis and arthritis.
Meanwhile, there is mounting evidence that babies born via caesarean section miss out on some of the microbes they would obtain through a vaginal birth, which may make them more vulnerable to allergies and asthma.
Factors Influencing The Infant Microbiome
The newborn gut microbiome is less diverse than that of the adult. During the first three years of life, the development of the gut microbiome is influenced by the gut-brain axis , and by maternal and neonatal exposures, including mode of delivery, antibiotic exposure, and feeding patterns . By the end of this period, the infant gut microbiome has assumed the diversity and composition of the adult gut and is generally characterized by species from four main phyla: Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria .

Baby Microbiome: Nurturing Your Baby’s Healthy Bacteria
“The microbiome is important for many aspects of health, from gut health to mental health to immune health, and we’re finding that the first couple of months of life is a really critical window for its development,” says Meghan Azad, a microbiome researcher and assistant professor of child health at the University of Manitoba.
Recent studies suggest that babies whose microbiome development is disrupted via a cesarean section delivery, early antibiotic use, limited breastfeeding, or other factors are at greater risk for a host of health conditions, including asthma and allergies, respiratory infections, irritable bowel disease, type 1 diabetes, and obesity. But they also suggest that no matter how a baby is delivered, parents can take steps to get baby’s bacterial ecosystem off to a good start.

Also, what is the microbiome and why is it important?
The gut microbiome plays a very important role in your health by helping control digestion and benefiting your immune system and many other aspects of health. An imbalance of unhealthy and healthy microbes in the intestines may contribute to weight gain, high blood sugar, high cholesterol and other disorders.
Secondly, where is the microbiome? The human microbiome is the collection of trillions of microbes living in and on the human body. It consists of about a thousand different bacterial species that reside in the mouth, gut and vagina, and on the skin.
Similarly one may ask, what is the microbiome?
The microbiome is the genetic material of all the microbes – bacteria, fungi, protozoa and viruses – that live on and inside the human body. The number of genes in all the microbes in one person’s microbiome is 200 times the number of genes in the human genome.

Maternal Microbiota Restoration During Pregnancy
Babies born vaginally to mothers who receive antibiotics during pregnancy or labor or to mothers with pregnancies complicated by immunological or metabolic disorders such obesity or diabetes may acquire a marginalized inoculum of beneficial bacteria. Restorative actions could be applied either to the disrupted maternal microbiota during pregnancy, to promote the newborn’s acquisition of a less-impacted microbiota, or directly to the infant after birth. The first approach would aim to alleviate the impact of disruptors on the maternal microbiota. This could be achieved through the administration of prebiotics and probiotics to the mother during pregnancy or labor, either as adjuncts to the antibiotic regimen or prophylactically to mothers with otherwise disrupted microbiota. A 2012 study by Stojanoviet al. examined the effect of intravaginal administration of Lactobacillus rhamnosus to 60 women once weekly for 12 weeks during the second and third trimesters of pregnancy . The study found that the probiotic helped maintain a vaginal microbiome free of pathogenic microorganisms and helped maintain a low vaginal pH. While these investigators examined the effects of probiotics on otherwise healthy pregnant women, such strategies could be employed for women with disrupted vaginal microbiota.

Untangling Microbes From Viruses
Most of what we know about the microbiome, their health benefits and impact on human disease is largely based on the role of the bacteria in our microbiome, said Lim, who is also an assistant professor at ASUs School of Life Sciences. Very little is known about whether the viruses are functioning in the same way.
Viruses are very simple microbes among the smallest microbes on earth. In order to survive and grow, viruses find their way into living cells. They can damage healthy cells, causing disease.
Prior studies found that the majority of the infants bacterial microbiome is inherited from their mother, said Lim. And here we found that only a small portion of the infants virome matches with their mother.
Lim and his team found that related infants shared a more similar gut virome and bacterial microbiome to their twin than to unrelated infants.
Our findings support that the newborns gut viruses are likely sourced from other environmental exposures. Lim adds that this may be why each twins viromes are more similar to one another than to other unrelated infants.
Bacterial 16s Rrna Gene Sequencing
One hundred milligrams of stool was disrupted by bead beating and DNA was extracted using QIAamp DNA Stool Mini Kit on a QIAcube automated DNA extraction unit. In parallel, four buffer-only controls were disrupted by bead beating and similarly extracted to serve as extraction negative controls. PCR was performed using Golay-barcoded primers specific for the V4 region . Reactions were held at 94°C for 2min to denature the DNA, with amplification proceeding for 40cycles at 94°C for 15s, 50°C for 30s, and 68°C for 30s a final extension of 2min at 68°C. Stool and buffer samples, as well as 4 water negative controls, were amplified in triplicate, combined, and cleaned using Agencourt Ampure XP beads . Equimolar libraries were pooled and sequenced using an Illumina MiSeq sequencer at the Center for Genome Sciences & Systems Biology at Washington University.

Pubmed On The Microbiome
|PubMed, a database maintained by the National Library of Medicine, is a wonderful repository of published biomedical literature. Not only can one search the database to find recent articles on myriad topics, but also one can explore the history of these topics. In this graph, Dr. Jonathan Eisen, a biologist at the University of California, Davis, shows the explosive growth of papers in the PubMed database found using the search term microbiome. Between 1956 and 1975, the number of papers in a given years never exceeded three. In 2015, nearly 5500 microbiome-related articles were published. And the numbers certainly will continue to increase.|
Is There Prenatal Maternalfetal Exchange Of Microbiota
The intrauterine environment during healthy pregnancy has been presumed to be free of bacteria , although recent evidence of microbes present in the amniotic fluid , umbilical cord blood , fetal membranes , and placenta of healthy term pregnancies after both vaginal and C-section delivery has challenged this belief. However, caution is warranted in the interpretation of results from studies using high-throughput sequencing on low biomass samples such as those from the placenta and other intrauterine environs, since the risk of contamination of bacteria-free samples is high and strict controls are needed to exclude contamination.

What Is The Microbiome
Picture a bustling city on a weekday morning, the sidewalks flooded with people rushing to get to work or to appointments. Now imagine this at a microscopic level and you have an idea of what the microbiome looks like inside our bodies, consisting of trillions of microorganisms of thousands of different species. These include not only bacteria but fungi, parasites, and viruses. In a healthy person, these bugs coexist peacefully, with the largest numbers found in the small and large intestines but also throughout the body. The microbiome is even labeled a supporting organ because it plays so many key roles in promoting the smooth daily operations of the human body.
Each person has an entirely unique network of microbiota that is originally determined by ones DNA. A person is first exposed to microorganisms as an infant, during delivery in the birth canal and through the mothers breast milk. Exactly which microorganisms the infant is exposed to depends solely on the species found in the mother. Later on, environmental exposures and diet can change ones microbiome to be either beneficial to health or place one at greater risk for disease.
What Is A Gut Microbiome
The tiny critters that live in our gut, or gut microbes, are hard workers in our intestinal tract. Our gut houses approximately 500 species of bacteria and 100 trillion bugs altogether. They help absorb and synthesize nutrients. How we digest our food relies heavily on our microbiome. In addition, our gut microbes are involved in metabolism, immune regulation, cognitive function, and mood. While we have good and bad bacteria in our body it is the balance between these that is important. Diversity is essential and we always want more good bugs than bad.
Good bugs also known as beneficial bacteria or commensal bacteria. These bugs reside in our gut.
Bad bugs may be harmless or harmful. They can cause illness, especially when they grow out of control.
A healthy gut has a diverse collection of bacteria. That means different and varied microbial species. This community of good bugs helps to fight off infection by providing immune defense. These bacteria are needed to break down carbohydrates or sugars, balance mood, get rid of toxins, and help our body absorb fatty acids so our cells can grow. Healthy gut bacteria strengthen the intestinal walls. They help keep bad stuff such as undigested food particles and toxins in the gut where it belongs instead of in the bloodstream where it can cause harm.

Fermented Foods Are Gut
Fermented foods are another great source of probiotics. The crowd favourite is yogurt, however, if youre going to be eating a lot of yogurt, make sure that it is sugar-free! There are several other options that are a great source of good bacteria. Kombucha is becoming a very popular source of probiotics. You can also eat things like pickles, kimchee, and kefir to ensure that youre getting enough live cultures to keep your gut healthy and happy.
Prevention And Microbiome Restorative Strategies
Since the evolution of the mammalian birthing process must be adaptive, its disruption may prevent natural development of the neonatal microbiome and increase neonates’ long-term risk of metabolic and immune diseases. In light of this, elevated rates of C-section delivery , pre- and perinatal antibiotic use , and formula feeding underscore the importance of promoting vaginal delivery and more conservative administration of antibiotics and a renewed emphasis on initiating and sustaining breastfeeding. Health policies and clinical practice models that prioritize vaginal childbirth, as well as a reevaluation of when C-sections are considered medically necessary, have been suggested as approaches to preventing medically unnecessary C-sections . Developing safe strategies that limit or alter the use of antibiotics during pregnancy are also needed , as is broader use of antimicrobial stewardship programs and evidenced-based policies such as the UNICEF/WHO Baby Friendly Hospital Initiative and counselors to increase breastfeeding . A list of potential strategies to prevent C-sections, perinatal antibiotic use, and formula feeding is given in .

One of these sources was the human microbiome. The microbiome is defined as the collective genomes of the microbes that live inside and on the human body.
How do we acquire our microbiome?
Microbiota may be passed on to offspring via bacteriocytes associated with the ovaries or developing embryo, by feeding larvae with microbe-fortified food, or by smearing eggs with a medium containing microbes during oviposition.

When Do Bacteria First Colonize The Body How Host
A current ongoing debate is whether gut colonization starts during pregnancy or at birth. Here, Joël Doré covers how host-microbe symbiosis is established in early life and its impact on later health outcomes of neonates.
The symbiotic relationship between host and microbes starts early in life and is important not only in terms of how the neonate microbiome ultimately develops, but also its potential impact on long-term infant health.
A current ongoing debate within the scientific community is whether gut colonization starts during pregnancy or at birth. Indeed, the crucial question of when bacteria first colonize the body has yet to be answered.
Microbial transfer at the feto-maternal interface
For long time, prevailing scientific dogma stated that neonates are born sterile and only upon delivery are they populated by microorganisms. For instance, in 1900, French pediatrician Henry Tissier declared: The fetus lies in a sterile environment.
Things changed in 1982, however, when a study found bacteria in the placenta. That discovery prompted scientists to accurately corroborate these findings.
By using both conventional culturing techniques and 16S ribosomal RNA gene and/or metagenomic sequencing in animal studies and humans in the mid-2000s, bacteria were also detected in what had been presumed to be sterile tissue from healthy term neonates. These included the placenta, amniotic fluid and meconium.

What Is A Healthy Microbiome And How Do We Get It
A healthy microbiome is considered to be one with a broad array of species, with some particular species that may be more beneficial, and some species that appear to be less helpful. Food has the most obvious influence on microbe composition, and some very elegant studies have explored this.
Studies with people from different cultural backgrounds and diets have looked at swapping their diets for short periods of time. It takes only a few weeks for the change in diet to have an effect on the microbiome! In general, a more processed diet typical in the industrialised world is associated with less microbial diversity and an overall less healthy microbiome.
So whats the significance of this mass assembly of microbes for our health? Far from being silent passengers, they are vital for our existence, but they can also spell trouble. Some inhabitants of the microbiome can be disease causing if left unchecked.
It is now understood that various species of microbes in the microbiome communicate with the immune system using biological signals. One of the main mechanisms of this interaction is via the blood cells circulating in the walls of the intestine where they come into close contact with the gut microbiome.
