The person-to-person transmission landscape of the gut and oral microbiomes - Jan 2023

Table of Contents of PDF

The human microbiome is an integral component of the human body and a co-determinant of several health conditions1,2. However, the extent to which interpersonal relations shape the individual genetic makeup of the microbiome and its transmission within and across populations remains largely unknown3,4.
Here, capitalizing on more than 9,700 human metagenomes and computational strain-level profiling, we detected extensive bacterial strain sharing across individuals (more than 10 million instances) with distinct mother-to-infant, intra-household and intra-population transmission patterns.
Mother-to-infant gut microbiome transmission was considerable and stable during infancy (around 50% of the same strains among shared species (strain-sharing rate)) and remained detectable at older ages.
By contrast, the transmission of the oral microbiome occurred largely horizontally and was enhanced by the duration of cohabitation.
There was substantial strain sharing among cohabiting individuals, with 12% and 32% median strain-sharing rates for the gut and oral microbiomes, and time since cohabitation affected strain sharing more than age or genetics did.
Bacterial strain sharing additionally recapitulated host population structures better than species-level profiles did. Finally, distinct taxa appeared as efficient spreaders across transmission modes and were associated with different predicted bacterial phenotypes linked with out-of-host survival capabilities. The extent of microorganism transmission that we describe underscores its relevance in human microbiome studies5, especially those on non-infectious, microbiome-associated diseases.

Unlocking the ‘gut microbiome’ – and its massive significance to our health - July 2021

The Guardian
Scientists are only just discovering the enormous impact of our gut health – and how it could hold the key to everything from tackling obesity to overcoming anxiety and boosting immunity

A few snips from their excellent overview

• "Your gut microbiome weighs about 2kg and is bigger than the average human brain. It’s a bustling community of trillions of bacteria, archaea, fungi and viruses, containing at least 150 times more genes than the human genome. We are filled to the brim with microbes, which form microbiomes on our skin, in our mouths, lungs, eyes, and reproductive systems. These have co-evolved alongside us since the beginning of human history. But the gut’s is the largest and most significant for our short- and long-term health. It is massively complex and its residents vary enormously from person to person. According to a study in 2020 by the European Bioinformatics Institute, which pooled more than 200,000 gut genomes to create a genetic database of human gut microbes, 70% of the microbial populations it listed – 2,000 species – hadn’t yet been cultured in a lab and were previously unknown."
• “Over the past 80 years and since the dawn of antibiotics, there has been multi-generational loss of microbes that appear to be important for human health,” he says. “They’re passed from mother to child [during birth, via breastmilk and skin contact] throughout the generations, but at some point in the last three or four generations, we lost some. We’re not entirely sure if the cause was our lifestyle, our diet, cleanliness in our homes or the use of antibiotics. We’re also missing certain immune stimulants that people in the developing world have plenty of.”
• To do this, microbes need about 30g of fibre a day, but the average intake in the UK is just 10-15g. Is this why modern, low fibre, ultra-processed, high-sugar diets seem so problematic for human gut health?
• The great opportunity – but also the great difficulty – of gut microbiome science is that poor gut health is associated with such a vast range of conditions, from obesity and degenerative brain diseases to depression, inflammatory bowel disease and chronic inflammation. “The microbiome is associated with everything,”
• "Spector’s 30-year-long study of 15,000 twins, TwinsUK, and his PREDICT studies have shown that even genetically identical people respond to the same foods very differently (our microbiomes are so variable that twins share only 30% of the same gut microbes)."
• "A very small Italian study using a similar commercial probiotic, Sivomixx, piqued his interest after it suggested acute Covid patients treated with it might be less likely to end up in ICU or to die, and eight times less likely to suffer respiratory failure. Bjarnason is hoping to start a larger study in the next few months."

Where are the different microbiomes in the human body?- Perplexity AI May 2024

The human body hosts a variety of microbiomes, each located in distinct anatomical sites. These microbiomes consist of diverse communities of microorganisms, including bacteria, archaea, fungi, viruses, and other microbes. Here are the primary locations of microbiomes in the human body:
1. Gastrointestinal Tract
Gut Microbiome: The largest and most diverse microbiome, primarily composed of bacteria, but also includes fungi, viruses, and archaea. It plays a crucial role in digestion, immune function, and overall health.
2. Skin
Skin Microbiome: Composed of bacteria, fungi, and viruses, the skin microbiome varies significantly across different areas of the body, such as the face, hands, armpits, and feet. It helps protect against pathogens and maintains skin health.
3. Oral Cavity
Oral Microbiome: Includes bacteria, fungi, and viruses found on the tongue, teeth, gums, and saliva. It is essential for oral health and can influence systemic health.
4. Respiratory Tract
Respiratory Microbiome: Found in the nasal cavity, throat, and lungs, this microbiome includes bacteria and viruses that can impact respiratory health and disease susceptibility.
5. Urogenital Tract
Vaginal Microbiome: Dominated by Lactobacillus species, it plays a key role in protecting against infections and maintaining reproductive health.
Male Reproductive Tract Microbiome: Includes bacteria found in seminal fluid, which can affect sperm quality and reproductive health.
__6. Mammary Glands
Breast Microbiome: Includes bacteria that can influence breast health and potentially impact breastfeeding.
7. Other Sites
Oral Mucosa and Saliva: These areas host diverse microbial communities that contribute to oral and systemic health.
Conjunctiva: The eye's surface has its own microbiome that helps protect against infections.

Each of these microbiomes is adapted to its specific environment and plays a unique role in maintaining the health and function of its respective body site. The composition and function of these microbiomes can be influenced by factors such as diet, lifestyle, genetics, and environmental exposures.
