When antibiotics attack microbes, their stressed neighbors ship them proteins to help them survive, new work suggests. Bacteria share DNA related to antibiotic resistance through a process called ...

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 ...

Researchers have shown that the most common rifampicin-resistance mutation in Mycobacterium tuberculosis not only helps 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, ...

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

Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but many operate in constant threat of being infected by viruses called phages ...

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 ...

Scientists have discovered a key 'survival gene' that prevents strains of tuberculosis (TB) from mutating into drug-resistant 'superbugs'. In a joint study, published today, Friday January 27th 2017, ...
