Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

Nobody wants to be average. But for a long time, scientists have found it convenient to think of bacterial cells as just that: "average." Researchers have traditionally relied on population-level ...

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can ...

As the number of antibiotic-resistant infections continues to rise, scientists are looking to bacteriophages (“phages”), viruses that infect bacteria, as an approach to tackling antibiotic resistance.

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...

Creating new technologically advanced sensors, scientists have engineered bacteria that detect the presence of tumor DNA in live organisms. Their innovation could pave the way to new biosensors ...
