Another last-resort antibiotic has fallen victim to the rapid evolution of drug-resistant superbugs. The powerful antibiotic combination ceftazidime-avibactam (CZA), widely used to treat severe ...

Scientists have discovered a way to control mutation rates in bacteria, paving the way for new strategies to combat antibiotic resistance. Antibiotics are given to kill bad bacteria; however, with ...

Bacteria need mutations -- changes in their DNA code -- to survive under difficult circumstances. When necessary, they can even mutate at different speeds. This is shown in a recent study by the ...

(DBenitostock/Moment/Getty Images) The combination drug ceftazidime-avibactam (CZA) is a last line of defense against the ...

The bacteria Mycobacterium tuberculosis, which causes the world's most infectious disease Tuberculosis (TB), can survive antibiotic treatment and live longer by changing their outer fat coating, ...

Scientists at National Taiwan University College of Medicine have discovered that cancer formation is not simply caused by ...

Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...

Researchers identify the antibiotic concentration where bacteria may be most likely to develop dangerous drug resistance.

Microbes that hitched a ride into orbit are not just surviving in space, they are changing in ways that give them startling new abilities. In the strange physics of microgravity, bacteria and viruses ...
