A wet market in China is suspected to be the source of the outbreak, but one thing to consider as we move forward is that the risk of another outbreak from other animal markets remains high.

But that microbiome can actually tell us some fascinating things about the animal or plant we’re looking at. So today, I’ll go through exactly what metagenomics is, and some of the information we can glean from a plant’s surface (I am a botanist after all).
