[life] Our Dust, Ourselves … The story your house dust tells about you … ‘The sex of a home’s human occupants also played a role in shaping the indoor ecosystem. Lactobacillus bacteria, which are a major component of the vaginal microbiome, were most abundant in homes in which women outnumbered men. When men were in the majority, however, different bacteria thrived: Roseburia, which normally lives in the gut, and Corynebacterium and Dermabacter, which both inhabit the skin. Corynebacterium is known to occupy the armpit and contribute to body odor. “Maybe it means that men’s houses smell more like armpits,” Dunn suggested. “That’s probably—microbially, that’s a fair assessment.” The findings may be due to sex differences in skin biology; men tend to have more Corynebacterium on their skin—and to shed more skin microbes into the environment—than women do. (In the paper, the researchers also acknowledge the possibility that a bachelor pad’s bacterial signature could be the result of “hygiene practices.”)’
