antibiotic resistance

Free-swimming bacteria settle on a surface to cooperate and form a protective biofilm.

Syphilis is among the oldest known sexually-transmitted infections. Scientists still struggle to detect and treat it.

Researchers use blue light therapy to treat infected burn wounds.

Studies are finding that a single course of antibiotics alters the gut microbiomes of healthy volunteers—and that it can take months or even years to recover the original species composition.

In Salmonella, two seemingly similar antibiotic survival strategies result from very different molecular mechanisms.

Researchers use genetic clues to track the spread of antibiotic resistant bacteria from the environment to patients.

To manipulate the microbiome, researchers engineered a CRISPR delivery system that precisely targets bacteria in the mouse gut.

Low doses of continuous penicillin exposure altered mouse pups’ microbiomes and gene expression in brain areas associated with emotional and cognitive function.

In a first, patients who hadn’t been treated with antifungals were found to carry Candida auris impervious to all three available classes of the drugs.

With multiple microbiota therapeutics in the pipeline for recurrent Clostridium difficile infection, clinicians foresee a shift in treatment options for the condition.

Bacteria-infecting viruses affect the composition and behavior of microbes in the mammalian gut—and perhaps influence human biology.

Phages interact with bacteria and eukaryotic cells in ways that researchers suspect influence mammalian health.

Researchers used a machine-learning platform to test more than 100 million molecules for antibacterial activity.
