Our results demonstrated which the chlorination process promoted the horizontal transfer of plasmids by purely natural transformation, which resulted from the exchange of ARGs across bacterial genera and also the emergence of recent ARB, along with the transfer of chlorine-wounded opportunistic pathogen from non-ARB to ARB. Considering that the transfer things had been rather proof against degradation via disinfection, this case poses a possible danger to community wellness.
