  • Instead, the gut bacteria "seem to induce some metabolic change that acts directly on the brain and the body, which mimics a state of protein satiety," Santos says. (eurekalert.org)
  • Kalman's laboratory is now investigating how indoles exert their effects in aging animals, how dysregulation of indoles produced by the microbiota contribute to frailty, and how indoles can be used to reverse these effects. (eurekalert.org)
  • In 2014, however, a German enforcement laboratory alerted EU officials to illegal GE bacterial contamination of a riboflavin supplement intended for animal feed. (greenmedinfo.com)
  • This discovery updates the long-held view that bacteria use their flagella mostly for movement, and demonstrates that flagella can also function as enzymes, like what happens with the spread of infection. (thedairysite.com)
  • What we found in this case is that many bacteria have repurposed their flagella to function as protein-degrading enzymes. (thedairysite.com)
  • There may be ways of using these enzymes in biotechnology to degrade things we want to break down, including biofilms, sticky colonies of harmful bacteria. (thedairysite.com)

  • Below is the STUDYAREA, use this to take a closer look some bacteria. (edu.au)
  • Toronto: Scientists have discovered a new source of neurotoxin, known for its paradoxical ability to remove wrinkles yet cause an illness associated with food poisoning from a strain of animal gut bacteria, a finding that can potentially expand its therapeutic applications. (india.com)
  • In sum, this study shows not only that gut bacteria act on the brain to alter what animals want to eat, but also that they might do so by using a new, unknown mechanism. (eurekalert.org)
  • This new study adds to a growing concern that concentrated animal feeding operation (CAFO) chickens may becoming a breeding ground for botulism, and related pathogenic organisms. (healthimpactnews.com)
  • A scientist sticks a cotton bud into the mouth of a grey seal to extract bacteria samples from around its tooth roots. (sciencenordic.com)
  • PhD student Mie Johanne Hansen, who has been affiliated with the project since 2010, has had the task of sticking cotton buds into the mouths of animals such as seals, sea lions, walruses, bears, otters and freshwater turtles to extract bacteria samples from around the animals' tooth roots. (sciencenordic.com)
  • Our first hypothesis was that these bacteria might be providing the flies with the missing essential amino acids," Santos explains. (eurekalert.org)
  • A class of chemicals made by intestinal bacteria, known as indoles, help worms, flies and mice maintain mobility and resilience for more of their lifespans, scientists have discovered. (eurekalert.org)
