Bacterial evolution is the process of heritable change in populations of bacteria over multiple generations. It occurs through mechanisms including natural selection and genetic drift, and can ...

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas ...

Their research, recently published in the journal Nature Communications, reveals that bacteria ... science, evolution, medicine, and public health. As researchers strive to identify, model ...

DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of ...

Point mutations are often thought of as the raw material of evolution; these small changes ... us insights into the evolutionary pressures on bacterial pathogens.

The bacteria is notoriously drug-resistant, and several antibiotic treatments are no longer effective in treating it. If evolution makes bacteria like this more invulnerable, prevention and ...

The bacteria regained motility not by reacquiring the lost gene . . . but instead by mutations in other genes that put their products to new uses.” There are still some big unanswered questions about ...

“It shows for the first time that something that is very important for the evolution of a pathogen—phage transfer—is triggered by the action of the pathogen itself during infection.” Some ...

DNA segments that can move from one part of the genome to another -- are key to bacterial evolution and the development of antibiotic resistance. Researchers have discovered a new mechanism these ...
