A fascinating ethnography of microbes that opens up new spaces for anthropological inquiry

 

The trillions of microbes in and on our bodies are determined by not only biology but also our social connections. Gut Anthro tells the fascinating story of how a sociocultural anthropologist developed a collaborative “anthropology of microbes” with a human microbial ecologist to address global health crises across disciplines. It asks: what would it mean for anthropology to act with science? Based partly at a preeminent U.S. lab studying the human microbiome, the Center for Genome Sciences at Washington University, and partly at a field site in Bangladesh studying infant malnutrition, it examines how microbes travel between human guts in the “field” and in microbiome laboratories, influencing definitions of health and disease, and how the microbiome can change our views on evolution, agency, and life.

As lab scientists studied the interrelationships between gut microbes and malnutrition in resource-poor countries, Amber Benezra explored ways to reconcile the scale and speed differences between the lab, the intimate biosocial practices of Bangladeshi mothers and their children, and the looming structural violence of poverty. In vital ways, Gut Anthro is about what it means to collaborate—with mothers, local field researchers in Bangladesh, massive philanthropic global health organizations, with the microbiome scientists, and, of course, with microbes. It follows microbes through various enactments in scientific research—microbes as kin, as data, and as race. Revealing how racial categories are used in microbiome research, Benezra argues that microbial differences need transdisciplinary collaboration to address racial health disparities without reifying race as a straightforward biological or social designation.

Gut Anthro is a tour de force of science studies and medical anthropology as well as an intensely personal and deeply theoretical accounting of what it means to do anthropology today.

Though nothing in the natural world would be quite the same without them, microbes go mostly unnoticed. They are the tiny, mighty force behind the pop in Champagne and the holes in Swiss cheese, the granite walls of Yosemite and the white cliffs of Dover, the workings of snowmaking machines, Botox, and gunpowder; and yet we tend to regard them as peripheral, disease-causing, food-spoiling troublemakers. In this book renowned microbiologist John Ingraham rescues these supremely important and ubiquitous microorganisms from their unwonted obscurity by showing us how we can, in fact, see them—and appreciate their vast and varied role in nature and our lives.

Though we might not be able to see microbes firsthand, the consequences of their activities are readily apparent to our unaided senses. March of the Microbes shows us how to examine, study, and appreciate microbes in the manner of a birdwatcher, by making sightings of microbial activities and thereby identifying particular microbes as well as understanding what they do and how they do it. The sightings are as different as a smelly rock cod, a bottle of Chateau d’Yquem, a moment in the Salem witch trials, and white clouds over the ocean. Together they summarize the impact of microbes on our planet, its atmosphere, geology, weather, and other organisms including ourselves, to whom they dole out fatal illnesses and vital nutrients alike.

In the end, Ingraham leaves us marveling at the power and persistence of microbes on our planet and gives credence to Louis Pasteur’s famous assertion that “microbes will have the last word.”
