The Scientist Speaks - Rising From the Dead: How Antibiotic Resistance Genes Travel Between Current and Past Bacteria

Heather Kittredge and Sarah Evans discuss the environmental conditions that facilitate natural transformation in bacteria’s native habitat.  

Written byNele Haelterman, PhD

Scientists have known for a long time that microbes can take up extracellular DNA fragments, and they have leveraged this transformation process to genetically modify bacteria in the lab. However, transformation is quite fickle and depends on creating the right balance of reagent concentrations and cellular conditions. How this process takes place outside of the petri dish, in more natural bacterial environments such as soil, has proven more difficult to determine. 

In this episode, Nele Haelterman from The Scientist’s Creative Services Team spoke with Heather Kittredge, a postdoctoral research associate at the University of Connecticut, and Sarah Evans, an associate professor of integrative biology at Michigan State University, to learn more about natural transformation in bacteria and its implications for the rise in antibiotic resistance. 

The Scientist Speaks is a podcast produced by The Scientist’s Creative Services Team. Our podcast is by scientists and for scientists. Once a month, we bring you the stories behind news-worthy molecular biology research.
