Soil bacterium tapped for penicillin guard duty

A common soil bacterium may hold the key to preserving the germ-killing power of penicillin. U.S. Department of Agriculture (USDA) scientists in Peoria, Illinois, helped mass produce the antibiotic during World War II to ...

Potential new way to limit antibiotic resistance spreading

One of the biggest current threats to global health is the rise of multi-drug resistant bacteria, caused by the spread of antibiotic resistance amongst them. In an attempt to fight this threat, EMBL researchers have unraveled ...
