Sometimes I come across a stock photo that is unintentionally funny. Here is another one.

An artist’s rendition of how microbes grow in the intestinal tract. Here you can see bacteria circling around microvilli. Or are they shiny pills in straight lines circling around sausages, or decaying fingers in plastic gloves?

Same villi but different bacteria. It’s a Fecal Microbiota Transplant!

And this one has no bacteria at all. I guess it represents the Germ Free Mouse.
