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

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.

Researchers explore how blood platelets sweep bacteria into aggregate bundles at sites of infection to help phagocytic cells dispose of them. 

Lab experiments and metagenomic analyses of flies’ resident bacteria indicate that the insects carry microbes from place to place on their legs.

Emerging infections provide clues about how pathogens might evolve when farm animals are protected from infection.
