E. coli sends out SOS when antibiotics attack, sparking emergency mode
Antibiotics damage E. coli DNA, including by causing formation of single strands of incomplete DNA inside the cell. When that happens, it’s like lighting a match under a smoke detector, according to a new study.

Temperature could be the new weapon in the battle against antibiotic resistance
Scientists have found that a small increase in temperature from 37 to 40 degrees Celsius drastically changes the mutation frequency in E. coli bacteria, which facilitates the development of resistance.
