  • Atomic-Level Motion May Drive Bacteria's Ability to Evade Immune System Defenses
    A study from Indiana University has found evidence that extremely small changes in how atoms move in bacterial proteins can play a big role in how these microorganisms function and evolve. The research, recently published in the Proceedings of the National Academy of ...More

  • Bacterial 'Supermachine' Reveals Streamlined Protein Assembly Line
    There are many processes that take place in cells that are essential for life. Two of these, transcription and translation, allow the genetic information stored in DNA to be deciphered into the proteins that form all living things, from bacteria to humans to plants. ...More

  • Lice and Bacteria are Partners in Parasitism
    Head lice have been stigmatized, quickly conjuring images of infested school children and parents combing through their hair. This social stigma reaches many of the estimated 14 million people who are annually infested in the U.S. alone. However, these blood sucking lice ...More

  • NSU Researchers Studying How to Disrupt Bacteria to Better Treat Infections
    Bacteria are everywhere. And despite widespread belief, not all bacteria are "bad." However, to combat those that can cause health issues for humans, there has been an over-reliance on the use of antibiotics -- so much so, that many of them are now proving ineffective due ...More

  • Biologists Discover 'Timesharing' Strategy in Bacteria
    Timesharing, researchers have found, isn’t only for vacation properties. While the idea of splitting getaway condos in exotic destinations among various owners has been popular in real estate for decades, biologists at the University of California San Diego have ...More

  • 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
