Whether in the human body or on surfaces, bacteria protect themselves from outside attackers using biofilms. Physicist ...

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

Researchers have uncovered the structure of a regulatory mechanism unique to bacteria, opening the door for designing new antibiotics targeted to pathogens. Cornell researchers have uncovered the ...

Near-weightless conditions can mutate genes and alter the physical structures of bacteria and phages, disrupting their normal ...

In most people, these bacteria coexist peacefully and contribute to a mutually beneficial relationship, with both human and ...

Zinc sits at the heart of many bacterial enzymes, so one of our immune system's simplest defenses is to keep zinc out of reach. Calprotectin, a neutrophil protein abundant at infection sites, is ...

San Diego State University (SDSU) researchers scraped tubeworms (Hydroides elegans) off the bottom of boats in the San Diego harbor and discovered that a beneficial bacterium that aids them in ...

Tubeworms (Hydroides elegans) are tiny marine creatures with hard shells that cause a lot of trouble and economic loss for boat and ship owners. They stick to the bottoms of boats and form ...

The surface of pathogenic bacteria like E. coli contains hair-like structures called pili, which help bacteria bind to a host cell and stimulate infection. Researchers identified a new stage of pilus ...

Researchers from the University of Maryland School of Medicine and their colleagues have identified the structure of the most lethal toxin produced by certain strains of Clostridium difficile bacteria ...
