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

A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail the ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

A new study finds that a trait helping a marine bacterium survive and flourish today may ultimately become its Achilles Heel as ocean conditions continue to shift.

One of the most abundant living organisms on Earth may also be one of the most vulnerable. A group of ocean bacteria known as ...

Researchers at Umeå University in Sweden published a study “Breaking barriers: pCF10 type 4 secretion system relies on a self-regulating muramidase to modulate the cell wall” in mBIO that describes ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

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 ...
