NewsAnother tick-borne disease to avoid: anaplasmosis in Canada
Move over, Lyme disease — there’s another tick-borne disease to worry about in Canada. Anaplasmosis, the second most common tick-borne disease in the country, can cause a range of health issues, including myocarditis, as a practice article shows.

NewsHelpful microbes could battle pathogens in our hospitals and schools - with the help of AI to make it work
Helpful microbes that combat harmful pathogens could be the answer to rising antimicrobial resistance, particularly within built environments such as hospitals, homes and schools, says a new review.

NewsGut bacteria linked to malnutrition may pass to younger generations
A new study suggests that an intestinal disorder linked to malnutrition and stunted growth may be transmitted from one generation to the next via the small intestinal microbiome.

NewsGut bacteria boost immune system and help send Vitamin A to T cells
Scientists have discovered that gut bacteria help regulate the development of the body’s immune system by directing the movement of vitamin A through a previously unrecognized cellular network.

NewsResearchers use friendly viruses to tackle inflammatory bowel disease
A research team has developed a targeted approach to treating inflammatory bowel disease (IBD) using bacteriophages, viruses that infect specific bacteria, to disarm harmful microbes without disrupting the broader gut ecosystem.

NewsTwo companion papers explain immune ‘exhaustion’ - and how we might prevent it
Chronic and viral infections can literally exhaust certain key cells in the immune system from a constant barrage of attacks. But a new pair of papers has now pointed a way to understand how this exhaustion happens at a molecular level.

NewsWarm temperatures disrupt spider sex-changing bacteria in dwarf-spiders across generations
A new study reveals that exposing dwarf spiders to a brief period of warm temperatures can disrupt a phenomenon where internal bacteria normally force genetic males to develop as females.

NewsHow immune cells in our gut mesentery fight salmonella
Researchers have found that immune cells in a portion of the abdominal cavity, called the mesentery, play a critical role in suppressing — or exacerbating — salmonella infection.

NewsDrug candidate treats severe fatty liver disease by protecting the gut in animal models
Researchers discovered that a potential drug treats severe fatty liver disease by improving gut health. It reversed metabolic dysfunction-associated steatohepatitis (MASH) in animal models by disrupting a disease-driving pathway that links the gut and liver.

NewsBronchiectasis and NTM Research Registry data featured in four World Bronchiectasis Conference abstracts
The Bronchiectasis and NTM Association announced that research leveraging data from the Bronchiectasis and NTM Research Registry was featured in four abstracts presented at the World Bronchiectasis Conference.

NewsNew study advances dry mRNA vaccine patch design
New research could help make future mRNA vaccines easier to store and distribute. The study identified conditions that help protect the particles that carry mRNA in dry vaccine patches, offering practical guidance for future patch design.

NewsEject! Bacteria discovered with the ability to jettison cells as a survival mechanism
Biologists have found that communities of bacteria are capable of ‘escape pod’ ejection strategies. They documented the biofilm ejection phenomenon for the first time while studying a bacterium known as hay bacillus (Bacillus subtilis).

NewsFighting the world’s deadliest infection with PAC-MAN and AI
Researchers have developed techniques that can speed up the search for better tuberculosis drugs. They first measure which chemical compounds are able to slip across the outer membrane and then use those measurements to predict other compounds that can get into the Mtb cell.

NewsTuberculosis vaccine changes brain’s immune environment and Alzheimer’s biomarkers in older adults
A study shows that BCG vaccines can alter immune responses and amyloid-beta biomarkers in non-Alzheimer’s participants, which may help explain previously observed links to lower disease risk.
-
NewsNew HIV vaccine shows unprecedented success in preclinical study
Scientists have developed an HIV vaccine that trains immune cells to see past HIV’s defenses. This HIV vaccine works by prompting the body’s immune system to make substantial numbers of rarely seen “broadly neutralizing” antibodies.

NewsPreparing for Andes virus outbreaks to prevent transmission in healthcare settings
Researchers examined past cases to help healthcare facilities and public health agencies prepare for future Andes virus outbreaks like the one that caused a cruise ship outbreak earlier this year.
-
NewsThe broader a fungus’s diet, the better it kills insects and helps plants
Entomologists have discovered that a single underlying trait—metabolic breadth, or the range of nutrients a fungus can use—links its ability to kill insects, partner with plants and thrive in different ecological roles.

NewsFeline fleas carry bacteria linked to human disease In South Texas, study finds
Researchers have identified the murine typhus pathogen in fleas found in the Rio Grande Valley, highlighting the importance of flea prevention for both pets and people.
-
NewsA subtle difference offers insight into bacteria survival strategies
Researchers have discovered that Bacillus subtilis employs a different survival strategy to E coli, raising the question of whether other types of bacteria use alternative strategies, and how this might help researchers think differently about antibiotic tolerance.

NewsCould your salad be the source? Pathologist discusses reported parasite outbreak in US
Amid reports of a parasite outbreak that has sickened people in several states across the U.S., a pathologist warns that it is likely linked to a widely distributed commercial food product.
