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 ...

Adaptive mutagenesis describes the capacity of bacterial populations to elevate their mutation rates in response to environmental stress, thereby enhancing the likelihood of generating beneficial ...

Transposon mutagenesis has emerged as a pivotal tool for dissecting the genetic basis of bacterial virulence and survival. By mobilising a transposable element into random chromosomal sites, ...

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas fluorescens, providing unprecedented insight into the relationship between gene ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...

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 ...

Researchers have discovered that a mutation in the cellulose making machinery of E. coli bacteria allows them to cause severe disease in people -- 'good' bacteria make cellulose and 'bad' bacteria can ...

There has been much theoretical debate about whether and how organisms can evolve to become better at evolving, but now a team of researchers has made it happen in a lab – and documented almost every ...

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 ...

Disinfectants such as bleach, acids, phenols, and alcohols are important weapons against infectious diseases. During the COVID-19 pandemic, as the coronavirus ran rampant across the world, experts ...
