HOW THE GUT MICROBIOME IS ESTABLISHED
Under normal conditions, the formation of the adult microbiome occurs over the first three years of life. This is affected by life events such as birth method, weaning, starting solid food, and primarily cessation of breastfeeding. At birth, the most common bacteria are aerobic bacteria such as Enterococcus and Staphylococcus. Later in adulthood, anaerobes prevail, with a prevalence of Firmicutes and Bacteroidetes species the most common types.
Birthing
The gut microbiome begins developing in the womb, however much of the gut microbiome is environmentally acquired from birth. It is majorly affected by the type of birth delivery (vaginal or caesarean) and early feeding (breast or bottle).
The vaginally delivered baby is initially colonised with the vaginal and distal gut bacteria of the mother, while babies delivered by Caesarean section (C-section) are colonised predominantly with the skin bacteria from the mother. Difference in the gut microbiome composition based on delivery type can be seen for several years. Caesarean delivery has been shown to influence the microbiota composition, and this change is associated with medical complications, such as coeliac disease, asthma, autism, and obesity.
The vaginal microbiome undergoes a dramatic shift in bacterial species in preparation for birth, principally characterised by a decrease in species diversity. Diversity is a measure of the richness and evenness characteristics of a community, often calculated as a specific "diversity index". The dominance of Lactobacilli species has been observed throughout pregnancy (and up to 6 weeks post birth for some women). These species are protective. It is understood that lactic acid produced by Lactobacilli, increase the pH of the vagina and prevent pathogens colonising the environment. The microbiome of the vagina following birth experiences another shift, and in most cases the return to species richness. That is linked to lowering oestrogen levels after the delivery or removal of the placenta.
Lactobacilli are important – these normally are the first to colonise in the infant’s guts as he/she passes through the birth canal. The passage through the birth canal gives the baby its first dose of microbes. A newborn is a sponge as it populates its own microbiome after leaving the sterile womb. The infant gut microbiome continues to develop until 2-3 years, after which it remains relatively stable throughout adulthood.
Breastfeeding
The initial microbial exchanges between mother and infant at birth and shortly thereafter by early feeding, are fundamental to a newborn’s microbiota, as these early colonisers play a very important role in the development of the newborn’s immune system and long term in the activity and function of the microbiome, particularly in the gut. The feeding method (breastfeeding vs. formula) along with weaning (timing of the introduction of solid foods) are important contributors in the development of an individual’s gut microbiome.
MAINTAINING THE MICROBIOME AS ADULTS
Is the gut microbiome unique to each person?
Everyone has a unique gut microbiome. But herein lies the problem. It’s difficult for scientists to determine a “normal” or “healthy” pattern of microbes because every body’s microbiome is different – even in identical twins! This makes working out what a healthy microbiome looks like challenging.
Diet and Nutrition for Improving the Microbiome
Feeding the gut microbiome is essential for its longevity. The types of food consumed has a significant impact on the population that survives. The typical Western diet is high in fat and low in fibre and has been linked to a decrease in overall bacteria and of the beneficial species. High fibre diets are more beneficial as this will provide good nutrients to the gut microbiome, increase the bacterial richness (the number of distinct species in the community) and boost production of short-chain fatty acids.
People can eat their way to good gut health. To do that, people must expand their food horizon.
For adults, diet is the most powerful influence on the microbiome. By regulating the food items consumed and in what quantities, it is possible to manipulate the population densities of the different microflora. The consumption of fibres (or prebiotics) can proportionately increase the diversity of these probiotic bacterial species in the gut. Bacteria metabolise these fibres, and the fermentation results in the production of short chain fatty acids, which nourish the gut barrier, enhance immunity, and reduce inflammation. Vegetables, herbal tea, fruits, red wine, and dark chocolate can come in handy in regaining the lost bacterial diversity. The essential components in these food items are the polyphenols—which have unique properties—the most important being their antioxidant characteristic.
The Gut Project is a citizen science project based in the UK. The project is an open-source crowd funded project that relies on volunteers sending their faecal samples in the post for analysis. The key finding in the project is that microbial diversity is key. A diet rich in prebiotics seems essential.
Eating a wide-range of plant-based foods such as seeds, herbs, spices, nuts, legumes, fruits, and vegetables – all provide fuel for microbes. Conversely, sugar, antibiotics and processed foods decrease the number and diversity of human microbiota.
Lifestyle and Other Factors
There are a variety of other factors that can influence the gut microbiome including:
- Exposure to pathogens – colonisation by pathogenic bacteria can induce inflammation in the GI tract which can destabilise the gut microbiome or outcompete the commensal bacteria causing further illness.
- Age – as people get older, their microbial diversity decreases and this reduction in diversity is correlated with nutritional status, increased inflammation, and frailty. Research now shows that long-living people (including those that live to 100 years) exhibit increased gut microbial diversity. If people want to live long lives, then it is critical to nourish gut microbes.
- Stress and Anxiety – stress and anxiety can affect gut motility, visceral perception, GI secretion and intestinal permeability. These can in turn negatively alter the composition of the gut microbiome.
- Medication – medications such as antibiotics and proton pump inhibitors (typically prescribed for acid reflux), can disrupt or diminish taxonomic diversity which can persist over time.

How can I start this course?
You can enrol at anytime and start the course when you are ready. Enrolments are accepted all year - students can commence study at any time. All study is self paced and ACS does not set assignment deadlines.
Please note that if a student is being assisted by someone else (e.g. an employer or government subsidy), the body offering the assistance may set deadlines. Students in such situations are advised to check with their sponsor prior to enrolling. The nominal duration of a course is approximately how long a course takes to complete. A course with a nominal duration of 100 hours is expected to take roughly 100 hours of study time to complete. However, this will vary from student to student. Short courses (eg. 100 hrs duration) should be completed within 12 months of enrolment. Certificates, Advanced Certificates and Awards (eg. over 500 hours duration) would normally be completed within 3 -5 years of enrolment. Additional fees may apply if a student requires an extended period to complete.
If a student cannot submit their assignments for 6 months to ACS, they should advise the school to avoid cancellation of their student
registration. Recommencement fees may apply.

This course has been designed to cover the fundamentals of the topic. It will take around 100 hours to complete, which includes your course reading, assignment work, research, practical tasks, watching videos and anything else that is contained in the course. Our short courses are a great way to do some professional development or to learn a new skill.
It’s up to you. The study hours listed in the course are a rough guide, however if you were to study a short course (100 hours) at 10 hours per week, you could finish the course in 10 weeks (just an example). Our courses are self-paced, so you can work through the courses in your own time. We recommend that you wait for your tutor to mark and return your assignment before your start your next one, so you get the benefits of their feedback.
The course consists of course notes, videos, set tasks for your practical work, online quizzes, an assignment for each lesson (that you receive feedback from your tutor from) and ends in an exam (which is optional, if would like to receive the formal award at the end), using our custom built Learning Management System - Login.Training.
