    The question whether pressure is an impediment to (microbial) life is surprisingly opposite what has been assumed for a long time. Anurag Sharma, a geochemist, James Scott, a microbiologist, and others at the Carnegie Institution of Washington performed an experiment with Diamond Anvil Cell and utilized "direct observations" on microbial ...

    Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms.

    The microorganisms that make up the gut flora in the gastrointestinal tract contribute to gut immunity, synthesize vitamins such as folic acid and biotin, and ferment complex indigestible carbohydrates. [109] Some microorganisms that are seen to be beneficial to health are termed probiotics and are available as dietary supplements, or food ...

  8. Pathogenic bacteria - Wikipedia

    en.wikipedia.org/wiki/Pathogenic_bacteria

    There are many types of antibiotics and each class inhibits a process that is different in the pathogen from that found in the host. For example, the antibiotics chloramphenicol and tetracyclin inhibit the bacterial ribosome but not the structurally different eukaryotic ribosome, so they exhibit selective toxicity. [ 28 ]
