  • Understanding C. auris transmission with the healthcare environment
    on June 23, 2019 at 6:31 pm

    Researchers have now shown that patients who are heavily colonized with Candida auris on their skin can shed the fungus and contaminate their surroundings. This finding provides an explanation for the extensive contamination that often occurs in healthcare facilities with C. auris outbreaks. These results can help inform infection control efforts. […]

  • Prolonged transmission of a resistant bacterial strain in a Northern California hospital
    on June 23, 2019 at 6:30 pm

    Researchers have used whole genome sequencing (WGS) to demonstrate transmission of a single bacterial strain that possessed a carbapenem-resistance gene in a northern California hospital. The gene armed the bacteria with resistance to carbapenems, a type of antimicrobial drug reserved as a last-line treatment for serious infections. […]

  • The solution to antibiotic resistance could be in your kitchen sponge
    on June 23, 2019 at 6:30 pm

    Researchers have discovered bacteriophages, viruses that infect bacteria, living in their kitchen sponges. As the threat of antibiotic resistance increases, bacteriophages, or phages for short, may prove useful in fighting bacteria that cannot be killed by antibiotics alone. […]

  • Cannabidiol is a powerful new antibiotic
    on June 23, 2019 at 6:30 pm

    New research has found that Cannnabidiol is active against Gram-positive bacteria, including those responsible for many serious infections (such as Staphyloccocus aureus and Streptococcus pneumoniae), with potency similar to that of established antibiotics such as vancomycin or daptomycin. […]

  • Ocean swimming alters skin microbiome, increasing vulnerability to infection
    on June 23, 2019 at 4:25 pm

    Swimming in the ocean alters the skin microbiome and may increase the likelihood of infection, according to new research. […]

  • Plants may be transmitting superbugs to people
    on June 23, 2019 at 4:25 pm

    Antibiotic-resistant infections are a threat to global public health, food safety and an economic burden. To prevent these infections, it is critical to understand how antibiotic-resistant bacteria and their genes are transmitted from both meat and plant-foods. Researchers have now shown how plant-foods serve as vehicles for transmitting antibiotic resistance to the gut microbiome. […]

  • Skin bacteria could save frogs from virus
    on June 22, 2019 at 2:07 am

    Bacteria living on the skin of frogs could save them from a deadly virus, new research suggests. […]

  • Combination of drugs may combat deadly drug-resistant fungus
    on June 21, 2019 at 7:49 pm

    Microbiologists have shown that a combination of anti-fungal and anti-bacterial medications may be an effective weapon against the recently discovered multidrug resistant, Candida auris (C. auris). […]

  • Antibiotic resistance in spore-forming probiotic bacteria
    on June 21, 2019 at 6:42 pm

    New research has found that six probiotic Bacillus strains are resistant to several antibiotics. Genetic analysis of other Bacillus strains has shown genes that contribute to antibiotic resistance towards various types of drugs and methods in which they can still grow in their presence. […]

  • Dissemination of pathogenic bacteria by university student's cell phones
    on June 21, 2019 at 6:42 pm

    New research has demonstrated the presence of S. aureus in 40% of the cell phones of students sampled at a university. S. aureus is a common cause of hospital and community-based infections and is currently considered an important pathogen because of its level of antibiotic resistance. […]

  • From sheep and cattle to giraffes, genome study reveals evolution of ruminants
    on June 21, 2019 at 6:03 pm

    A detailed study of the genomes of 44 species of ruminants gives new insight into the evolution and success of these mammals. […]

  • 'Sneezing' plants contribute to disease proliferation
    on June 21, 2019 at 6:03 pm

    '''The jumping droplets, at the rate of 100 or more an hour, are a violent expulsion of dew from the surface. It's good for the plant because it is removing spores from itself, but it's bad because, like a human sneeze, the liquid droplets are finding their way onto neighboring plants. ' […]

  • 'DNA microscopy' offers entirely new way to image cells
    on June 20, 2019 at 9:21 pm

    Rather than relying on optics, the microscopy system offers a chemically encoded way to map biomolecules' relative positions. […]

  • Phenols in cocoa bean shells may reverse obesity-related problems in mouse cells
    on June 20, 2019 at 8:46 pm

    A new study suggests that three of the phenolic compounds in cocoa bean shells have powerful effects on the fat and immune cells in mice, potentially reversing the chronic inflammation and insulin resistance associated with obesity. […]

  • Animals' brain activity 'syncs' during social interactions
    on June 20, 2019 at 7:35 pm

    Egyptian fruit bats and mice, respectively, can 'sync' brainwaves in social situations. The synchronization of neural activity in the brains of human conversation partners has been shown previously, as a result of one person picking up social cues from the other and modulating their own behavior based on those cues. These studies suggest that something similar occurs when animals engage in natural social interactions. […]

  • New study maps how ocean currents connect the world's fisheries
    on June 20, 2019 at 7:35 pm

    It's a small world after all -- especially when it comes to marine fisheries, with a new study revealing they form a single network, with over $10 billion worth of fish each year being caught in a country other than the one in which it spawned. […]

  • Treatment for common cause of diarrhea more promising
    on June 20, 2019 at 7:35 pm

    Researchers have figured out how to grow the intestinal parasite Cryptosporidium in the lab, an achievement that will speed efforts to treat or prevent diarrhea caused by the parasite. […]

  • Animals may have more than one means of surviving hypoxia
    on June 20, 2019 at 7:34 pm

    A tidepool crustacean's ability to survive oxygen deprivation though it lacks a key set of genes raises the possibility that animals might have more ways of dealing with hypoxic environments than had been thought. […]

  • Research details response of sagebrush to 2017 solar eclipse
    on June 20, 2019 at 4:14 pm

    The short period of darkness caused a significant reduction in photosynthesis and transpiration in the desert shrub, but not quite to the levels of nighttime, according to some of the most detailed research on plant response to solar eclipses ever reported. […]

  • Spiders risk everything for love
    on June 20, 2019 at 4:14 pm

    A biology study finds that blue jays can easily spot wolf spiders engaged in their courtship rituals. The results demonstrate the powerful influence of sexual selection. […]
