Not as much as you’d think, according to Richard Spague’s personal testing. On Ubiome, he reports he had an initial drop in numbers and some alteration in species, but everyone came right back to normal within a few days. Very hopeful for those of us undergoing colonoscopies who don’t really want to start from scratch.
In the area of infertility, any little thing can make a difference. So when researchers found a difference in bacteria in semen, that raises some concerns. Infertile men had higher levels of: “Staphylococcus aureus (16.9%), Staphylococcus saprophyticus (9.2%), Escherichia coli (6.9%), Proteus mirabilis (3.4%),Klebsiella spp (2.3%), Pseudomonas aerouginosa (1.1%), and Proteus vulgaris (2.3%).”
The response was to look at supplementing men with probiotics orally, which doesn’t address the oral/topical split in the microbiome. More importantly, the male population is very likely to reflect the female vaginal population. Doing that follow-up testing would likely increase the effect of the results. If both partners are infected with species that are inflammatory, that’s going to impact fertility. But they then need to use topical probiotics to reverse the situation.
Don’t be scared off, you can become almost as educated as an expert very quickly because the field is so new. Here’s an animated five minute cartoon version of what we know.
We all know that many things can delay a child’s development. Sometimes it seems miraculous that children develop at all. Now we can show that antibiotics delay the gut’s development, affecting the entire child.
We know that antibiotics disrupt gut bacteria, and we know that disrupted gut bacteria lead to adult illnesses. So the researchers were simply connecting the dots between antibiotic use and adult illnesses.
“Researchers demonstrated that an infant’s age could be predicted within 1.3 months based on the maturity of their gut bacteria. This finding could lead to a clinical test and interventions for children whose microbiome is developmentally delayed due to antibiotics”
The greatest difficulty will be in finding a group of children with untouched, completely functional gut bacteria to use as a control group.
I’ve been trying to explain the ins and outs of the microbiome to patients and just gave up and wrote a short book to go through the permutations. Here it is, months of research in a short, hopefully entertaining book form.
Where would you find the most diverse microbiome? In New York, at Times Square, probably in someone sleeping on the ground? Nope. You’d find it somewhere remote: “the most diverse collection of bodily bacteria yet in humans among an isolated tribe of Yanomami Indians in the remote Amazonian jungles of southern Venezuela.” In comparison, “the microbiome of people living in industrialized countries is about 40 percent less diverse”.
