Anti Probiotics?

2018-09-11 21:17:24.684234+00 by Dan Lyke 0 comments

Human gut study questions probiotic health benefits:

Cell: Post-Antibiotic Gut Mucosal Microbiome Reconstitution Is Impaired by Probiotics and Improved by Autologous FMT (PDF). https://doi.org/10.1016/j.cell.2018.08.047

Cell: Personalized Gut Mucosal Colonization Resistance to Empiric Probiotics Is Associated with Unique Host and Microbiome Features. https://doi.org/10.1016/j.cell.2018.08.041

The upshot appears to be that:

  • Expelled fecal matter doesn't really give enough information about what bacteria are in the mucosal lining to be a useful diagnostic tool.
  • There are some people whose guts will be populated by probiotics, and some whose native gut bacteria will suppress the newly introduced bacteria.
  • In the study on repopulation after an antibiotic series, the control group's natural biome repopulated fairly quickly, but for both of the groups that were normally either resistant or not to the probiotic population, the probiotics dominated the gut for a long time. So taking probiotics after antibiotics may actually long-term fuck up your gut biome.

(You should probably use "Text" mode: URLs will be mostly recognized and linked, _underscore quoted_ text is looked up in a glossary, _underscore quoted_ (http://xyz.pdq) becomes a link, without the link in the parenthesis it becomes a <cite> tag. All <cite>ed text will point to the Flutterby knowledge base. Two enters (ie: a blank line) gets you a new paragraph, special treatment for paragraphs that are manually indented or start with "#" (as in "#include" or "#!/usr/bin/perl"), "/* " or ">" (as in a quoted message) or look like lists, or within a paragraph you can use a number of HTML tags:

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
