In this episode, we chat with Jaelle Brealey about salmon microbiome and macrobiome. We discuss salmon health and zoom in and out of different compartments to see what bacteria are in the salmon gut, as well as in tapeworms that live in the salmon. Think Matryoshka dolls! Yes, tapeworms don’t have an intestine but they have their own microbiome! Now that the can of worms is open, we have the foundation to answer many other questions that are important for both basic science, as well as applied science, especially related to health.
