ScienceLifeImmunology deep divesScientist interviewsPanel discussionResearch-focusedStandalone episodesEnglish

A podcast about the body's defenders against disease.

Why listen

Immune turns immunology into a working conversation among scientists, led by Vincent Racaniello, Cindy Leifer, Brianne Barker, and Stephanie Langel. Episodes move between journal-club style panel discussions and interviews with researchers, so listeners hear both the mechanics of immune cells and the human stories behind discoveries. It is best for curious science listeners who want real depth without a formal classroom feel.

The Holobiont — Animals, Microbes, and Ecology

Matters Microbial #130: The Holobiont — Animals, Microbes, and Ecology May 19, 2026 Today Dr. Kevin Kohl, Associate Professor of Biological Sciences at the University of Pittsburgh, joins the #QualityQuorum to discuss how he and his colleagues study the interplay between animals, their resident gut microbes, and the overarching concept of the holobiont. Host: Mark O. Martin Guest: Kevin Kohl Subscribe: Apple Podcasts, Spotify Become a patron of Matters Microbial! Links for this episode The One Health Microbiome Center at Pennsylvania State University. A very fine essay on the holobiont concept for non-microbiologists. A general introductory overview of the holobiont concept. The holobiont concept and the coral symbiosis. A partial history of the development of the holobiont concept. Dr. Casadevall suggests that context and thus outcomes describes the term "pathogen," and a similar analysis applies to the holobiont. A very short description of the holobiont concept. Another overview of the holobiont concept in general, coauthored by Dr. Kohl. Some basic rules for thinking about the holobiont concept. A video introduction to the holobiont concept, by Dr. Seth Bordenstein. I highly recommend this essay by the science writer Carl Zimmer, "The Human Lake," to think of the connections between lake ecology and microbial interactions with humans. Another wonderful article recommended by Dr. Kohl, by Dr. Ma
