Extracellular appendages on gut bacteria accelerate the transfer of antibiotic-resistance genes. “The death toll from antimicrobial resistance is expected to match cancer by 2050, meaning we urgently ...

New research shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut. Bacteria evolve rapidly in the human ...

Bacteria are constantly moving by help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like “speaking to each other”, and thus acquire new ...

Genes responsible for antimicrobial resistance (AMR) can spread from microbe to microbe through circular genetic material called plasmids, and this lateral transfer occurs in the gut. This week in ...

Claims that hundreds of bacterial genes have been transferred directly into humans are unfounded, according to a study published in June 21 Nature. The initial report by the International Human Genome ...

A carefully controlled lettuce irrigation study reveals that while secondary-treated wastewater can still carry antimicrobial resistance risks, tertiary treatment dramatically limits what reaches the ...

Bacteria evolve rapidly in the human gut by sharing genetic elements with each other. Bacteriodales is a prolific order of gut bacteria that trade hundreds of genetic elements. Little is known, ...
