It turns out that we also have microbes called archaea living in and on our bodies. They are part of our microbiome (community of microbes living in and on us, which also includes bacteria, viruses, and fungi ). Archaea constitute a domain or kingdom of single-celled microorganisms. These microbes are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells. Archaeal cells have unique properties that separate them from bacteria and eukaryotes. Archaea were initially classified as bacteria and thought to only exist in extreme environments (such as hot springs and salt lakes), and given the name archaebacteria, but this classification is now outdated. We now know that archaea live in less extreme places, including oceans, marshlands, animals, and humans. So little is known about archaea that not even medical schools discuss this topic. This may be due to the fact that we currently don't know of any archaea that are human pathogens (that is, that cause illness) or parasitic. They are generally viewed as mutuals (the relationship is beneficial to both organisms) or commensals (they benefit, but don't help or harm the other organism).
