Bacteria can tolerate high levels of antibiotics in salt
In the natural environment, bacteria can experience salt stress, for instance, due to spontaneous water evaporation from bio-aerosols. We monitored the proliferation of the bacteria, Mycobacterium smegmatis, over multiple generations in a microfluidic chip. Surprisingly, in elevated salt concentrations, the bacteria could tolerate high concentrations of antibiotics, indicating salt-induced drug resistance. See our publication: DOI: 10.1039/D5LC00713E (Paper) Lab Chip , 202
