Questions about the The Microbiome poster

What’s on the The Microbiome poster?

A definition and 6 facts worth remembering. The community of microorganisms living in and on a host, most densely in the large intestine, with roles in digestion, immune development and metabolism. Bacterial cells roughly equal human cells — about 1:1, not 10:1.; Most gut microbes cannot be cultured; sequencing revealed them.; They ferment fibre into short-chain fatty acids.; They contribute to immune system development.; Composition varies enormously between individuals.; Antibiotics disrupt it, sometimes for months.; Ratio — ~1:1; Densest — colon; Species — hundreds; Faecal microbiota transplant is an established treatment for recurrent C. difficile i…. Much microbiome research is correlational and in mice. Be cautious with strong causal claims about human health.

Who is the The Microbiome poster for?

The Microbiome belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning microbiology can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the The Microbiome poster?

Roughly as many bacterial cells as human cells. The old 10:1 figure was wrong. A wall chart earns its place by being glanceable from where the work is happening, so The Microbiome belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.

What other posters go with The Microbiome?

Antibiotic Resistance, How Antibiotics Work and Aseptic Technique sit alongside The Microbiome in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Antibiotic ResistanceHow Antibiotics WorkAseptic Technique

Is the The Microbiome poster free to download and print?

Yes. The Microbiome downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the The Microbiome poster print at?

The Microbiome is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of The Microbiome loses nothing.Printing guide
