Opportunistic pathogens
Germs that only become a problem when the balance is off. 8 chapters – expand
- Level:Intermediate Opportunistic pathogens Germs that are always there and only become a problem when the balance tips. AntibioticsAcid blockersMedicationProbioticsGut infectionsInflammationTests and diagnostics Promising How we rate the evidence Established Recommended in medical guidelines or supported by several consistent meta-analyses of randomised human studies. Well supported Several randomised studies in humans with largely consistent results. Promising Single randomised or controlled studies in humans, not yet independently confirmed — or many consistent observational studies. Plausible Two cases: first observational or pilot studies with small samples — or a settled basis that is not in dispute, such as movement, sleep or meal pauses. But not tested in humans for symptoms. Experimental Barely studied in humans. Mainly lab and animal studies or theoretical reasoning; whether it helps is open.

Microbial diversity
Why many different species keep the gut stable. 1 chapter – expand
- Level:Intermediate What a household shares: microbes between people, dogs and cats People who live together swap bacteria constantly: through hands, kitchen, bathroom, kisses and the animal on the sofa. What studies on shared bacterial strains show, what is useful about it, which pathogens and resistant bacteria really do get passed on, and why shared bacteria are not proof of transmission.
