Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led ...

Bacteria can play established roles both as pathogens during infection but also as part of the host microbiota. The immune response to bacterial infection is a critical defence strategy protecting the ...

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 ...

If you have had strep throat or an ear infection, there's a good chance you received amoxicillin or penicillin to effectively ...

Researchers at the University of Queensland (UQ) have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The ...

Immune cells that eat bacteria in the body don't stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells ...

An article highlights new insights into the PARIS, an immune system that bacteria use to respond to viral infections. Scientists at Montana State University have been studying unique immune systems ...

A mechanism of antiviral immunity in bacteria has been characterized. A research team from Umeå University (Sweden) has uncovered a mechanism for how bacteria build up antiviral immunity against ...

A study led by David Sancho at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) in Madrid reveals how an increase in intestinal permeability allows the natural gut bacteria to cross the ...

Your immune system is your body’s built-in defense network, working nonstop to protect you from bacteria, viruses, and other ...

Postbiotics are the beneficial compounds produced when gut bacteria, including probiotics, break down prebiotics ...
