bacteria, microbiology, disease & medicine

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.

The Salk Institute researcher was one of the first to show that killing a pathogen isn’t the only way to survive an infection.

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.

The gut microbiome has been linked to depression, schizophrenia, and other neurological conditions, but it’s not yet clear whether the relationship is causal.

The agency issued a safety warning after two patients contracted antibiotic-resistant infections and one of the patients died.

Beads filled with bacterial colonies indicate which antimicrobial compounds are working.

Bacteriologist Alice Evans identified the pathogen that causes undulant fever, leading her to push for the pasteurization of milk.

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.
