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.
