Most bacteria, including many bacterial pathogens, are surrounded by an outer protective layer of sugar molecules, known as a ...

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

Rivals or allies—how do bacteria and fungi interact in our bodies? Until now, bacteria on our mucous membranes were primarily considered to be antagonists of fungi, as they can inhibit their growth.

In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the ...

Antibiotic treatments are losing effectiveness against a range of common bacterial pathogens, including E. coli, K. pneumoniae, Salmonella and Acinetobacter, according to a warning issued by the World ...

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean ...

Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, derived from the Greek word for bacteria-eaters, or in shortened form, "phages." Scientists ...
