Researchers at the RIKEN, Japan have discovered that acetate, a major metabolite produced by some intestinal bacteria, is involved in regulating other intestinal bacteria. Experiments specifically showed that acetate could trigger an immune response against potentially harmful bacteria. These discoveries will lead to the development of new ways to regulate the balance of intestinal bacteria.
Contrary to popular belief, early bacterial evolution is not driven by random-point mutations.
Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. UBC Okanagan researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise.
A small regulatory RNA found in many problematic bacteria, including Escherichia coli, appears to be responsible for managing the response of these bacteria to environmental stresses. Professor Charles Dozois from Institut national de la recherche scientifique (INRS) and doctoral student Hicham Bessaiah see a promising avenue for more effective treatment of antibiotic-resistant bacteria. Their results have been published in the journal PLOS Pathogens.
While several biology techniques have undergone significant technical advances that have allowed their high-throughput implementation, assessing the resistance levels of plant varieties to microbial pathogens remains an arduous and time-consuming task. In response to this, Pujara and collaborators took advantage of the naturally occurring luminescence of a deep-sea shrimp to engineer a light-producing bacterial reporter that allows the quantification of plant resistance levels through imaging.
A recent study by researchers at the University of Arizona College of Medicine - Phoenix defines a mechanistic role for an understudied bacteria family in gynecologic disease.
Humans have known for over two thousand years that shipworms, a worm-like mollusk, are responsible for damage to wooden boats, docks, dikes and piers. Yet new research from the University of Massachusetts Amherst published in Frontiers in Microbiology reveals that we still don't know the most basic thing about them: how they eat.
Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They are essential to preventing and treating infections, but they also pose a global threat to public health when microorganisms develop antimicrobial resistance. A University of Pittsburgh lab studied the mechanisms behind bacterial resistance to silver nanoparticles to determine if their ubiquitous use is a solution to this challenge or if it is perhaps fueling the fire.
Research led by Newcastle University's Dr Hannah Kreczak is the first to identify the processes that underpin the trajectories of microplastics below the ocean surface. Publishing their findings in the journal Limnology and Oceanography the authors analysed how biofouling - the accumulation of algae on the surface of microplastics, impacts the vertical movement of buoyant particles.
In new research from the University of Minnesota, University of Notre Dame and Duke University, scientists found that genetics nearly always plays a role in the composition of the gut microbiome of wild baboons.
