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

Cryo-electron tomography reveals how Salmonella sets up physical interactions with host cells.

By combining experimental data with computer models, researchers were able to predict a pathogen’s evolution toward more virulence.

Some beetle species may have evolved to tunnel into the ground to escape the pathogens that abound on dead and rotting animals.

The microbiologist was known for his work on bacterial antibiotic resistance and infectious disease.

A new technique could allow researchers to better understand bacteria-host interactions over the course of an infection.

See the University of Pennsylvania's David Roos explain the process of parasite replication.

Researchers reconstruct images of a virus that infects Escherichia coli bacteria.

Only a few labs will earn funding for such “gain-of-function” research on SARS, MERS, and other deadly diseases.
