  1. 'Strong muscles start in the gut'

    "Aging naturally weakens our muscles, but researchers at Leiden University Medical Center and the Universities of Granada and Almería have found a gut bacterium that may help turn the tide. Their findings, now published in the scientific journal Gut, show that Roseburia inulinivorans is linked to stronger muscles in both people and mice."

    "Older adults who carried this bacterium had 29 percent stronger handgrip strength than those who didn’t.” In young adults, higher levels of Roseburia inulinivorans were associated with stronger muscles and better overall fitness."

    "After clearing the mice’s gut bacteria using antibiotics, they introduced human strains of Roseburia inulinivorans for eight weeks. […] The mice became 30 percent stronger, developed larger muscle fibers and produced more fast‑twitch fibers, the kind needed for quick, powerful movements."

    "The team also found that the bacterium changed how the muscles used certain building blocks and activated energy‑related pathways inside the muscle. “These metabolic changes may help explain why the muscles grew stronger"

    "Another key observation is that levels of Roseburia inulinivorans naturally decline with age. “This could partly explain why muscle strength drops as we get older"

  5. #Escherichia albertii, initially identified as Hafnia alvei, by the commercial identification biochemical strip, API 20E, was isolated from an infant with diarrhea in Bangladesh in 1989. However, this #bacterium was later renamed as a novel species, E. albertii

  6. @DenisCOVIDinfoguy (Whooping Cough is the effect of fixed toxin from the infecting organism, Bordetela pertussis, which is a #bacterium, not a virus)

    Good advice, minor correction.

  7. Singapore orders recall of French soft cheese over possible Listeria risk

    This photograph shows a camembert cheese in Quimper on Aug 13, 2025. More than 40 batches of cheese have been recalled due to suspected contamination with Listeria bacteria, which can b…

  8. More than a billion tons of #chitin are produced on Earth each year. This study shows that the soil #bacterium #Streptomyces venezuelae thrives on chitin from #insect #exoskeletons, using a potent mix of chitinases and a dedicated chitobiose importer @PLOSBiology plos.io/45sg4S5

  13. Ancient Killer Is Rapidly Becoming Resistant to #Antibiotics, Warns Study
    Currently, antibiotics are the only way to effectively treat #typhoid, which is caused by the #bacterium #Salmonella enterica serovar Typhi (S Typhi). Yet over the past three decades, the bacterium's resistance to oral antibiotics has been growing and spreading.

  14. New #Bacteria Have Been Discovered on #China's #SpaceStation
    On Earth there is no record of Niallia tiangongensis, a #bacterium found aboard the #Tiangong station that appears to be well adapted to conditions there.
    It is unclear whether the newly discovered microbe evolved on the #space station or whether it is part of the vast sea of as yet unidentified microorganisms on Earth.

  15. Scientists have discovered a previously unknown #bacterium aboard #China's Tiangong space station. "It has been named Niallia tiangongensis, and it inhabited the cockpit controls on the station, living in microgravity conditions," Chinese astronauts collected swab samples from the space station in May 2023, which were then frozen and sent back to #Earth for study

  16. New #Bacteria Have Been Discovered on a #Chinese Space Station

    It is microscopic and rod-shaped, can create #spores, and may have evolved to #survive hundreds of miles above our planet’s surface.

    This #bacterium, never before seen on Earth, was detected on #China's #Tiangong #space station. It has been named Niallia tiangongensis, and it inhabited the cockpit controls on the station, living in #microgravity conditions.
