Antibiotics can destroy many types of bacteria, but increasingly, bacterial pathogens are gaining resistance to many commonly used types. As the threat of antibiotic resistance looms large, ...

Bacteria can acquire resistance to antibiotics through random mutations in their DNA that provide them with an advantage that helps them survive. Finding genetic mutations, and discovering how they ...

Researchers report that phage resistance in ocean bacteria can alter growth, metabolism and sinking behavior, revealing a ...

Queensland researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic ...

That stickiness matters. When bacteria clump together, they sink faster, carrying carbon away from the surface ocean and into ...

In the 1940s, the famous Luria–Delbrück experiment showed that bacteria evolve resistance to drugs they'd never encountered thanks to a random mutational process. When you purchase through links on ...

A bacterial toxin called colibactin, produced by certain strains of E. coli, appears to alter gut DNA in a way that prompts colon cancer, researchers report in the journal Nature. Photo by ...

Disinfectants such as bleach, acids, phenols, and alcohols are important weapons against infectious diseases. During the COVID-19 pandemic, as the coronavirus ran rampant across the world, experts ...

Some people with bacterial gut infections remain symptom-free while passing the infection on to others. A new study has shed light on the interplay between bacteria, diet and the immune system that ...
