 Yes. Yes, we are. So we take mainly teeth and then we crush them and extract the DNA out of those teeth. And then we sequence all of the DNA in the DNA extract. And that means that you'll get DNA from the host, so that's the human, but you'll also get DNA from a bunch of different microbes. So some microbes will be from the soil where the skeleton was buried, but some microbes will also be from pathogens.
