Previously Unknown Antibiotic Resistance Widespread Among Bacteria

June 5, 2023 — Genes that make bacteria resistant to antibiotics are much more widespread in our environment than was previously realized. A new study shows that bacteria in almost all environments carry resistance genes, with a risk of them spreading and aggravating the problem of bacterial infections that are ...

New Class of Antibiotics to Fight Resistant Bacteria

June 1, 2023 — Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria's ...

How the Flu Virus Hacks Our Cells

May 31, 2023 — Influenza epidemics, caused by influenza A or B viruses, result in acute respiratory infection. They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu. A team has now identified how the influenza A virus manages to penetrate ...

Genetic Change Increased Bird Flu Severity During U.S. Spread

May 30, 2023 — Scientists found the virus strains that arrived in 2021 soon acquired genes from viruses in wild birds in North America. The resulting reassortant viruses have spread across the continent and caused more severe ...
