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?
