  • Plays an important role in health and disease
27
Q

What factors influence diversity and health of the microbiome?

A
  1. Genes
  2. Age
  3. Environment
  4. Stress
  5. Diet
  6. Physical activity
28
Q

What are the impacting factors on gut microbiome?

A
  1. Diet
  2. Stress
  3. Infant feeding method (breast fed vs formula)
  4. Birthing process (if through vagina different microbiome)
  5. Lifecycles stages
  6. Geography
  7. Pharmaceuticals
29
Q

What has been found in umbilical?

A

PFOS and PFOA

30
Q

Is it true that diet including whether a baby is breast milk or formula milk fed effects their microbiome?

A

true

31
Q

Is it true that in utero the foetus is not exposed to the maternal microbiome?

A

false, in utero foetus is exposed to both microbial DNA and maternal microbes

32
Q

Is it true that the microbiome is the bacteria, fungi, parisites and viruses found in GI tract?

A
  • False
  • The microbiome consists of bacteria, fungi, parasites and viruses including their genes found co-existing throughout the human body.
  • This can also be found within and on all multicellular organisms, not just in the GI tract of humans.
  • Microbiota is the term usually used for a group of micro-organisms found within a certain environment.
  • For example, the ‘gut microbiome’ refers to all microbes and their genetic material found in the gut, whereas ‘gut microbiota’ refers to the micro-organisms in the gut only
33
Q

Does the method of delivery of a baby influence its microbiome?

A
  • Yes
    1. Babies born vaginally are initially colonised by organisms from the maternal vagina to which they are exposed during delivery
    2. Babies delivered via caesarean section are mostly colonised by maternal skin flora and tend to have significantly less diverse and fewer bacteria in their gut in early life compared with those delivered vaginally
34
Q

Does the microbiome have immunomodulatory properties?

A
  • Yes
  • It is a complex and evolving field
  • The microbiome curbs the growth of pathological microorganisms and has a role in balancing proinflammatory and anti-inflammatory signals
35
Q

What is the microbiome?

A

trillions of bacteria, fungi, parasites and viruses and their own genetic material that co-exist on or inside our bodies

36
Q

Is a person’s microbiome unique?

A

yes

37
Q

What is the largest microbiome?

A
  1. GI tract microbiome is the largest
  2. The large intestine constitutes over 70% of the microbiome with Firmicutes and Bacteroidetes being the two main phyla present
38
Q

What are the differences in distribution of species throughout the GI tract?

A
  • temporal (oesophagus to colon)

- spatial (luminal versus mucosal)

39
Q

Where does the GI tract microbiome derive its nutrition from?

A
  • from host dietary intake

- shed epithelial cells

40
Q

What physiological processes is the gut microbiome involved in?

A
  • Metabolite and vitamin production
  • Immune system
  • Nervous system
41
Q

What is one of the main roles of the gut microbiome?

A

producing secondary metabolites by breaking down luminal compounds to more useful metabolites

42
Q

What can the reactions do?

A
  1. detoxify ingested toxins to make these less harmful

2. gut microbiome capable of synthesising antimicrobial peptides

43
Q

What can dietary fibres and resistant starches only be broken down and fermented by?

A

enzymes from the gut microbiome in the colon

44
Q

What does fermentation predominatelt by Firmicutes release?

A

short chain fatty acids (SCFAs) which

are a rich source of energy and lower the pH in the colon

45
Q

What does pH of the colon dictate?

A

the
type of micro-organisms capable of surviving there and also interacts with both the immune
and nervous systems

46
Q

What do SCFAs do?

A
  1. SCFAs (particularly butyrate) play a vital role in maintaining local (gut) and systemic immune homeostasis
  2. May also play a role in gut-brain axis
47
Q

What vitamin production is undertaken by gut microbiome?

A
  1. Vitamin K synthesis

2. Several components of vitamin B

48
Q

What must the GI tract mucosal immune system tolerate in homeostasis?

A

beneficial commensal micro-organisms whilst simultaneously preventing overgrowth of pathogens to keep us healthy

49
Q

Why is this helpful and protective from an evolutionary perspective?

A
  1. If a ‘toxin’ such as pathological organism enters the gut, dendritic cells can detect this and help initiate an acute proinflammatory immune response to rid the body of the toxin
  2. However, if routinely exposed to lower level harms common in modern day life for example, a poor
    diet or exposure to an unhealthy microbiome in the lumen, a low level, chronic
    inflammatory state can occur which is detrimental to health and associated with chronic
    disease
50
Q

What are dendritic cells always doing?

A

constantly monitoring their environment and contents

within the gut (including the microbiota) and produce an appropriate immune response

51
Q

What type of immune response can there be?

A

either be pro-inflammatory or anti-inflammatory responses through cytokine
release and regulatory T cell production depending on what they find

52
Q

What else can an unhealthy diet damage?

A
  1. damage the integrity of the delicate and barrier between the
    gut and rest of the body
  2. making it permeable, sometimes referred to as a ‘leaky’ gut
53
Q

What can this leaky gut lead to?

A

This can lead to harmful lipopolysaccharides (LPS’s) which form the outer coat of certain
types of microbiota crossing into the blood stream

54
Q

What do the LPS do?

A

In the gut lumen, LPS’s don’t cause
any damage, but if they cross over into the blood stream, this causes a stress and
inflammatory response

55
Q

What else does the gut microbiome do?

A

While the precise mechanisms are unclear it is speculated that through direct
and indirect pathways the gut microbiome can regulate innate and adaptive immune cells.
