A review chapter that I put together last year is now available online or by purchasing the textbook!  The chapter explores the current breadth of knowledge about methanogenic archaea that live in the human digestive tract and their involvement in human gut diseases. These archaea produce methane using hydrogen and carbon products that bacteria create during fermentation, and it’s unclear how the interaction of host immune system, bacterial diversity, and archaeal diversity can trigger disease or convalescence.

It’s based on a preliminary study I did with my Ph.D. advisor https://acbs.cals.arizona.edu/people/andre-denis-wright and gastroenterologist https://www.uvm.edu/medicine/medicine/gastro/?Page=profile.php&bioID=22563 on the connection between methanogen diversity in the intestines and exhaled breath methane.
