Bacterial mutagenicity assays are indispensable tools in toxicology for the detection of DNA-reactive agents. The most widely used method is the bacterial reverse mutation test, commonly known as the ...

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to ...

Some antibiotics stop bacteria from growing without actually killing them, allowing infections to return later. Scientists at the University of Basel created a new test that tracks individual bacteria ...

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 ...

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