Bacterial and viral acute sinus infections typically display similar symptoms. The duration of the infection can help determine if it is viral or bacterial. Many viruses, such as the ones that cause ...

In the emergency department, distinguishing between bacterial and viral infections can be challenging, leading to inappropriate use of antibiotics that may contribute to the development of bacterial ...

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 ...

The idea that a single-celled bacterium can defend itself against viruses in a similar way as the 1.8-trillion-cell human immune system is still “mind-blowing” for molecular biologist Joshua W. Modell ...

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 ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.

University of Toronto researchers have discovered nine new genes used by bacteria to protect themselves against phages—viruses that infect them. In a study published in Nature Microbiology, the ...
