Mapping Bacterial Neighborhoods in the Gut
Now, in collaboration with the Broad Institute of MIT and Harvard, Caltech researchers have discovered that a certain species of bacteria behaves differently depending on where in the gut it takes up residence. The work was done in mouse models, but mapping the geography of microbial populations in the gut—collectively referred to as the gut microbiome—may be crucial for one day being able to treat and reshape a human microbiome gone awry.
