There are many ways of classifying bacteria. One method is based on the cell membrane. In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, ...

Scientists are uncovering the secrets of one of nature's most primitive immune systems through studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes.

Fermented foods generally last longer, but even with foods that contain good bacteria, you have to watch out for invasions of ...

One might want to start loading up on food rich in good bacteria, because another study has highlighted the influential role of these good bacteria on health and well-being. Harmless bacterium found ...

A team led by Paul Hergenrother at the University of Illinois Urbana-Champaign has discovered a new antibiotic that exclusively targets gram-negative bacteria and avoids wiping out the ecosystem of ...

Antibiotics like amoxicillin can increase your risk of developing a yeast infection. This happens because antibiotics can ...

A team from the Max Planck Institute for Evolutionary Biology has discovered a new class of bacterial mobile genetic elements that use giant viruses—known as jumbo phages—to move between cells. The ...

Scientists increasingly realize the importance of gut and other microbes to our health and well-being, but one University of California, Berkeley, biologist is asking whether these microbes - our ...

Common medications can accumulate in gut bacteria, a new study has found, altering bacterial function and potentially reducing the effectiveness of the drug. These interactions – seen for a variety of ...

Genome fragments are sometimes transferred from bacteria to eukaryotes via horizontal gene transfer (HGT). When these DNA fragments contain genes, these genes can retain their functionality in some ...
