Researchers could one day use the method to deliver antibiotics to topical wounds infected by hard-to-treat masses of bacteria.

Tackling Antibiotic Resistance: Viruses to the Rescue

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

Metabolic disrupters, phages, and other approaches are going to be needed to treat the broadest possible range of patients infected by bacterial pathogens resistant to multiple drugs.

Bacteria grow and divide in microfluidic channels.

The Tufts University biologist and physician sounded the alarm on the effects of antibiotic use in animals.

Oxytetracycline, approved by the US government to combat citrus scourge, may not work—at least not as a spray.

In Niger, fewer kids die when health workers administer azithromycin routinely, perhaps because of a shift in the composition of gut microbes.

Research in mice and humans is beginning to establish a link between the composition of microbes in the gut and immune responses to tumor cells, but the mechanisms are not yet clear.

A membrane pump found in most bacteria helps E. coli acquire drug resistance from neighboring cells even while they’re exposed to antibiotics, a new study shows.

Delivery guidelines should be updated to reflect these results, the authors write.

Governor Phil Murphy signs a bill honoring the bacterium discovered in his state’s soil, now known for its antibiotic compounds used to treat tuberculosis.

The former Columbia University professor’s early work helped illuminate the structure of penicillin, allowing chemists to make variants and broaden the scope of antibiotic treatments.

A report also concludes that an investment of $2 per person per year could forestall that fate.

A photograph of microbes producing the antibiotic actinorhodin is one of many images on display at the Oxford University Museum of Natural History this winter.

Experiments in mice and people find that probiotic supplements don’t consistently change the composition of the gut microbiome, and may have adverse effects after antibiotics.

Scientists work out the specific genes and biochemical steps required for digesting the very drugs designed to kill microbes.

Drug-free environments, such as a designated ward in a hospital, might reduce the strength of selection for resistance.

The antimicrobial drug neomycin protects mice from some viral infections, complicating the picture of the relationship between antibiotics and susceptibility to viruses.
