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 ...

Even highly antibiotic-resistant bacteria become more vulnerable when their cell wall transport system is disrupted, ...

Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness. Weill Cornell Medicine investigators have ...

Queensland researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic ...

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

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 ...

For about 40% of people diagnosed with colorectal cancer (CRC), the tumor carries a mutation in a gene called KRAS. Many of those mutations have been linked to shorter survival and more aggressive ...

Certain bacteriophages found in the human gut have mutation hotspots scattered throughout their genomes that help them modify key defense genes, researchers report. Every 15 minutes, someone in the ...

Do bacteria mutate randomly, or do they mutate for a purpose? Researchers have been puzzling over this conundrum for over a century. In 1943, microbiologist Salvador Luria and physicist turned ...
