  • How Gut Inflammation Drives the Evolution of Harmful Bacteria
    Inflammation in the gut helps bacterial viruses spread to other strains of bacteria and promotes their success, a new study in mice finds. The results hint that using a vaccine that reduces gut inflammation may be helpful in treating some infections. Bacteriophages, or ...More

  • Biologists Uncover a New Way That Bacteria Lay Siege to Neighboring Cells
    Bacteria have evolved some seriously complex strategies to communicate with one another, and the resulting interactions are a delicate balance of cooperation and, in some cases, competition. These intraspecies exchanges take place within contact-dependent growth inhibition ...More

  • WHO Issues List of Bacteria for Which New Antibiotics are Needed Urgently
    The World Health Organization (WHO) today published its first ever list of antibiotic-resistant "priority pathogens" – a catalogue of 12 families of bacteria that pose the greatest threat to human health. The list was drawn up in a bid to guide and promote ...More

  • New Algorithm Identifies Gene Transfers Between Different Bacterial Species
    Gene transfers are particularly common in the antibiotic-resistance genes of Streptococcus pneumoniae bacteria. When mammals breed, the genome of the offspring is a combination of the parents' genomes. Bacteria, by contrast, reproduce through cell division. In theory, this ...More

  • Bacteria Remodel Their Genes to Infect Intestines
    Infectious diarrhea, a common disease of children, is responsible for more than 2 million infant deaths annually in developing counties alone. A primary cause of this and other devastating conditions is enteropathogenic bacteria, which attack the intestinal tract when ...More

  • Rice University Study Probes Microbe, Virus Co-Evolution
    A Rice University study suggests that researchers planning to use the CRISPR genome-editing system to produce designer gut bacteria may need to account for the dynamic evolution of the microbial immune system. CRISPR is an acquired immune system that allows bacteria and ...More
