Gut bacteria – some are better than others, and it’s not necessarily a “more is better” situation

Here’s an interesting one:

A few different teams found that a single strain of bacteria promoted growth as well as a full set of bacteria. This was found to be the case with 2 very different strains of bacteria. This “proves that biological functions provided by a bacterial community in your intestines are shared among community members and may be redundant.”
