In this Review, Smith, Foster and colleagues explore the protective strategies of bacteria, including the mechanisms, evolution and clinical implications of these ancient defences. They discuss new therapies for treating disease and how to minimize resistance evolution....
Bacterial evolution: Historical influences on antibiotic resistanceNewer quinolones, including garenoxacin, are characterized by excellent activity against gram-negative bacteria along with high activity against gram-positive organisms. All the new quinolones have similar in vitro potencies against most gram...

University of Pittsburgh School of Medicine researchers repeatedly exposed bacteria to the antibiotic ciprofloxacin to force rapid evolution. As expected, the bacteria developed resistance to the drug, but surprisingly, their lifestyle affected which specific adaptations emerged, according to a study publish...
Once acquired, a new resistance mechanism evolves according to the dynamics of the microenvironment; there is then a high probability that it is transferred to other species or to an avirulent strain of the same species. A well understood model for studying emerging antibiotic resistance and its ...
We outline how interspecies interactions can affect the responses of individual species and communities to antibiotic treatment, and how these responses could affect the strength of selection, potentially changing the trajectory of resistance evolution. Finally, we identify key areas of future research ...
Evolution of Antibiotic Resistance Altered by Bacterial Lifestyle Calcified Bacteria Sheds Light on the Health Consequences of the Evolving Diet 2 Comments stephen schaffer on July 17, 2021 7:44 am a really poorly written article with way to little information. sorry, bad job. Reply Andy ...

Together, these results reveal an overlooked mechanism by which opportunistic pathogens that produce natural toxins can dramatically modulate the efficacy of clinical antibiotics and the evolution of antibiotic resistance, both for themselves and other members of clinically relevant polymicrobial communities. ...
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 result in adaptations to environmental change or host immunity. Because of their short generation times and large...
