Spores can shift the microbium by up to 30 %, right? Which is like a 20 to 30 trillion organism change in as little as a couple of weeks. That's nature at its best. And we studied this in the case of c diff, for example, clusterdum defise. We did a study with a cleveland clinic that's published now. It's out there. People can read it. What we were looking to see is, how do our spores compete against clusterdum deficienti, right? For in a model way, you have colonized clusterdm defic so we sent the spores in, and this was inan animal model study that has been
