In response to Minnie’s question you said the following: “Indeed, my underarm microbiome changed to a dominance of corynebacteria. After three years, I was able to change it back to a dominance of non-odorous bacteria. This happened in summer, while painting and renovating the house, and by co-incidence. I was also working constantly with my arms, with one and the same painters T-shirt. After showering, I wore again the same unwashed painters T-shirt to proceed the ‘dirty’ work. This helped in taking over the shirt microbiome, from which afterwards we got to know mainly the ‘good’ bacteria grew in.” I don’t 100 percent understand and would like a little clarification. Why would it make a difference that you worked constantly with your arms? Did the good bacteria grow on the shirt and take over the bad ones on your skin?
Hi there. Well, to be honsest, I also don’t quite understand how it went. I think a combination of factors led to change my underarm microbiome again. Working with the arms can lead towards a higher influx of oxygen in the armpit region. More oxygen means more aerobic bacteria and less smelly bacteria. But I think the trick was indeed with the T-shirt: the dirty shirt was full with the ‘good’ bacteria, which were taken over on my washed skin. Still, a lot of variables and unknown things. In the lab we are working these things out. Best, Chris
