Antibiotic resistance linked to common household disinfectant triclosan | ScienceDaily

Scientists from the University of Birmingham and Norwich Research Park have discovered a link between a major mechanism of antibiotic resistance and resistance to the disinfectant triclosan which is commonly found in domestic products.

Researchers made the unexpected finding that bacteria that mutated to become resistant to quinolone antibiotics also became more resistant to triclosan.

The scientists showed that the quinolone-resistance mutation altered the way the bacteria package their DNA inside a cell and that these mutants had also turned on various self-defence mechanisms — together these gave triclosan resistance.
