Rice University scientists are developing strategies to keep germs from evolving resistance to antibiotics by heading them off at the pass.
Bacteria use antibiotics as a weapon and even produce more antibiotics if there are competing strains nearby. This is a fundamental insight that can help find new antibiotics. Leiden scientists Daniel Rozen and Gilles van ...
Health experts have warned for years that the overuse of antibiotics is creating "superbugs" able to resist drugs treating infection.
Researchers have found antibiotic resistance genes are spreading to bacteria of Australian wildlife, including captive sea lions and rock wallabies, and the little penguins of Sydney Harbour.
The Mexican company Grupo Nutec manufactured a new product, Plofora, based on plant extracts. It replaces antibiotics for farm animals in order to naturally activate specific genes that strengthen animals' immune systems ...
