Whether in the human body or on surfaces, bacteria protect themselves from outside attackers using biofilms. Physicist ...

Antimicrobial resistance—when bacteria and fungi defend themselves against the drugs designed to kill them—is an urgent ...

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis while sparing healthy microbes in the mouse gut ...

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

Bacterial infections pose significant challenges to agriculture and medicine, especially as cases of antibiotic-resistant bacteria continue to rise. In response, scientists are elucidating the ways ...

Antibiotic resistant bacteria already cause tens of thousands of fatal infections every year, and that number is expected to continue to rise. Even while many commonly used antibiotics are becoming ...

Researchers at WashU Medicine have developed a nasal vaccine against the highly pathogenic H5N1 avian influenza virus, or bird flu, which has jumped from wild birds to livestock to humans. When tested ...

Scientists have made a major breakthrough in the accuracy and speed at which often deadly pathogen infections can be identified and treated. This is time that, in many cases, is critical to saving a ...

As oceans warm, pathogenic bacteria are turning up more frequently in northern regions, scientists say. By Roni Caryn Rabin On a warm day in early July, Ed Houlihan guided kayakers on a four-mile trip ...

The CDC estimates that roughly 1 in 31 US hospital patients contract at least one infection linked to their health care every day. The CDC said the results of the 2024 report show the continued need ...
