Microbiome Monitoring: Smart Toilets, Precision Medicine, and the Post-Genomic Bowel

 Megan MacGregor  August 11, 2026

Imagine that every time you poop, your hygiene routine involves depositing your used toilet paper into a toilet-side receptacle. As you wash your hands, the device mixes, processes, and extracts microbial DNA from your stool. It sequences the microbial DNA for a real-time readout of your microbiome (the microbial genomes from within your gut, or at least the ones that made it to your stool), automatically sending the information to a large-scale microbiome database that integrates it into its data, algorithms, and analytic programs. The program connects to an app on your phone, telling you that based on your personal version of a healthy microbiome, today your microbiome is looking a little low in the bacterial species Akkermansia municiphila and high in some risky metabolites (the molecular outputs of some of your gut microbes). It recommends that you eat extra polyphenol- and fiber-rich foods today, and asks if you want a recipe for a berry- and seed-laden oatmeal for breakfast. The vision I describe here is a technoscientific imaginary: a shared vision of a future, mediated by science and technology (Marcus 1995). Technoscientific imaginaries are always embedded in historic and cultural contexts and narratives, which shape what future visions we find possible, desirable, and relevant. In this post, I examine how this technoscientific imaginary draws on narratives about promise and precision medicine inherited from genomics, as well as newer ones based in new understandings of the human microbiome and its powerful associations with many aspects of human health.

Microbes and the Permeable Body: Rethinking Health Through the Holobiont

Donna Haraway opens When Species Meet with the proclamation that “human genomes can be found in only about 10 percent of all the cells that occupy the mundane space I call my body” (Haraway, 2007). The rest of the human body is comprised of bacteria, viruses, archaea and other microorganisms – largely invisible to the human eye, but nonetheless living on and within us. In recent years we have seen a proliferation of research and attention towards these microorganisms, particularly in the gut, skin, lungs, and mouth, with each comprising their own microbiome. Although this research is still developing, it is increasingly clear that these microorganisms may actually be fundamental to the development and functioning of human bodies. (read more...)

“Blooming Biomes Mean Blooming Profits”: ‘Nature-based’ Industrial Farming and the Politics of the Industrial Animal Microbiome

Industrial trade shows are curious places. Potential customers milling around more than 500,000 square feet of exhibit space; technoscientific exuberance and hype; snappy names and enticing displays; hungry and nondiscriminatory grabs for whatever is free; networking spaces facilitated by their offerings of food and drink; and extravagant product demonstrations all collide in the fervor of selling, or at least showing off, the most innovative piece of technology. Here are other details that make industrial trade shows political places of assemblage: the racialized, gendered nature of maintenance and service work that help make an event as large as this run; the uneven representations of corporate power through the different sizes of trade floor allotment and who runs them; the ways in which some companies use gendered labor and performance (high heels, tight and low-cut shirts, and bright red lipstick) to attract onlookers to their booth; and the juxtaposition between these efforts against a company’s tagline behind them that says, as one example, “Leading the world to the future.” This blog post draws on participant observation at industrial agribusiness trade shows, specifically the International Production and Processing Expo (IPPE). The IPPE is the largest trade show displaying domains (technology, service, innovation, supplies) related to the entire gamut of processing, feed manufacture, and the production of eggs, meat, poultry. Given the enormity of all there is to study, my efforts are mainly focused on the marketing materials around and promises of future feed that industry trade shows enroll. As such, this blog post focuses on a few developments in the arenas of ‘nature-based’ methods of industrial farming that target the industrial animal microbiome. (read more...)

The biology, as astonishing as it is, does not tell us what it will mean. -Stephan Helmreich, “Homo Microbis” (2014, 4) Within microbiome research, the human body can be recast as a host of microbial ecologies, a “supraorganism” or “holobiont.” From this comes new ways of understanding and treating digestive diseases as well as illnesses associated with brain functioning, like depression and Alzheimer’s. This research reflects the increasing emphasis in the life sciences on “life as process” (Dupre and O’Malley 2007, Dupre 2020), and in the social sciences on the body as “biosocial” (Niehwöhner and Lock 2018). We take up these insights and examine one way that these ontologies of body and environment circulate in public ways by analyzing how the human body is depicted in relation to microbes and environments through public visualizations of the human microbiome.
