Disinfectants train superbugs to resist antibiotics.

This is why I only treat wounds with prayer and urine. From BBC News:

Disinfectants could effectively train bacteria to become resistant to antibiotics, research suggests.

Scientists know bacteria can become inured to disinfectant, but research increasingly shows the same process may make them resistant to certain drugs.

This can occur even with an antibiotic the bacteria have not been exposed to.

Writing in Microbiology, the National University of Ireland team, who focused on a common hospital bacterium, urges a rethink of how infections are managed.
