According to a study published last week in the journal mBio, a team of researchers from the University of Colorado at Boulder (USA) showed that showerheads can harbor non-tuberculous mycobacteria linked to a pulmonary infection.
As part of the research, the authors collected bacterial biofilm samples from showers in 656 US households. and 13 European countries. Laboratory tests have revealed that showerheads often harbor many colonies of mycobacteria that vary with geographic location, chemical composition of the water and the source of the vital fluid.
Non-tuberculous mycobacteria were much more abundant in showers. they received water from the municipal supply system compared to those receiving well water, and they were more abundant in US households than in European households.
The researchers think that these models are probably partly due to the difference. water disinfectants based on chlorine. The material with which the showerhead is manufactured would also have an influence on bacterial buildup, because according to the study, a greater concentration of mycobacteria was detected in metal showers compared to plastic showers .
Non-tuberculous tumors develop in areas where lung diseases are common, such as southern California, Florida and New York.
"There is a fascinating microbial world that thrives in your shower and you can be exposed every time to taking a shower," said Noah Fierer, co-author of the study. "The actions, of the types of water treatment systems that we use to the materials in our pipes, can alter the composition of these bacterial communities," Fierer added, noting that "there There is absolutely no reason to fear the shower.
