NewsInuit recommendations to address high rates of tuberculosis in Nunavik, Quebec
Tuberculosis rates for Inuit living in Nunavik, the Inuit lands in northern Quebec, are 1,000 times greater than among non-foreign-born Quebeckers, and underresourcing of local health care adds to hardship from the disease, found new research.

NewsNovel treatment protocol targets the deadliest cases of C. difficile infection
A new study demonstrated that fecal microbiota transplantation (FMT) can rapidly reverse systemic inflammation and improve survival in patients with fulminant Clostridioides difficile infection.

News New virulence regulator of diarrhea pathogen discovered
While it was already known that RNA molecules enable direct temperature sensing in the model organism Yersinia pseudotuberculosis, a new study reveals that the Fis protein also plays a regulatory role at the DNA level.

NewsNew strategy to break resistance-yield trade-off in rice by pathogen-inducible gene expression
A research team has developed a genetic strategy to enhance broad-spectrum disease resistance in rice without compromising plant growth and yield, a major challenge in crop breeding.

NewsNitrogen addition reshapes forest microbes: A five-year insight into community dynamics
A new study reveals how long-term nitrogen enrichment influences soil bacterial communities and network stability, with surprising insights into ecological processes and dissolved organic matter’s critical role.

NewsScientists reveal the potential of a tiny soil bacterium to beat the Haber-Bosch process
A new review finds that biological ammonia production offers strong potential as a cleaner, greener alternative to the costly Haber-Bosch process. Microbes such as Azotobacter can produce ammonia under ambient conditions and atmospheric pressure.

NewsMillions-of-years-old insect symbioses are surprisingly fragile
An introduced bacterium displaces the sawtoothed grain beetle’s symbiotic partner, leading to the complete collapse of a previously stable symbiosis within a few generations.

NewsOne of cholera’s great enemies is found in the human gut
Cholera-causing bacteria are locked in an evolutionary arms race with a viral nemesis, according to a new genomic study. Researchers found that in the Ganges Delta, cholera bacteria rapidly gain and lose special armour that protects against attacks from the virus, known as bacteriophage ICP1.

NewsScientists warn antibacterial soaps and wipes can fuel antimicrobial resistance
An international team of scientists is warning that everyday antibacterial soaps, wipes, sprays, and other “germ‑killing” products are quietly contributing to the global rise of antimicrobial resistance (AMR) while providing no added health benefit for most consumer uses.

NewsSmall intestinal bacterial overgrowth - and your allergy symptoms
A review suggests that small intestinal bacterial overgrowth (SIBO) may be associated with symptom exacerbation in atopic diseases, such as bronchial asthma, food allergies, or chronic urticaria.

NewsDecoding the chemical messengers: Gut microbes talk to the whole body through metabolites
A comprehensive review systematically maps how bacterial metabolites shape immune responses and diseases across organs.

NewsEngineered enzyme breakthrough offers sustainable solution for polyurethane plastic recycling
A research team has elucidated, for the first time, the catalytic mechanism by which the esterase Aes72 hydrolyzes urethane bonds in polyurethane (PU), and by engineering the enzyme to further enhance its catalytic efficiency.
-
NewsScientists develop therapeutic, nasally delivered DNA vaccine for tuberculosis
Research shows the vaccine — in combination with drug therapy — accelerated a relapse-free TB cure in mice, improved activity of a drug-resistant TB regimen and stimulated immune responses in nonhuman primates.

NewsA study links armed conflict in Colombia with higher tuberculosis cases and mortality
Areas with the highest intensity of conflict between 2008 and 2019 recorded a higher disease burden, highlighting the need for control strategies tailored to each territory.

NewsViruses ‘eavesdrop’ on each other – but it can backfire
Viruses can “eavesdrop” on each other using chemical signals – but it can backfire for the eavesdropper, new research shows. Scientists studied chemical communication by phages, viruses that infect bacteria.

NewsSimple blood test for gut bacteria metabolites could spot dementia years earlier
Scientists have discovered that subtle changes in the blood may reveal the earliest signs of cognitive decline long before symptoms become obvious.These changes are caused by chemicals produced by gut bacteria - reinforcing the idea that the gut–brain connection plays an important role in early memory changes.

NewsIntroducing environmental microbiota to urban homes shifts the indoor microbiome
Introducing forest soil on an entryway doormat shifted the indoor microbiome of Finnish homes closer to bacterial profiles found outdoors, with less contribution from human-associated bacteria, a new study shows.

NewsThesis confirms algae have strong wound-healing, skin-protective, and immune-supporting properties
New research demonstrates that polysaccharides extracted from various seaweeds and freshwater cyanobacteria possess remarkable bioactive properties and can accelerate wound healing, reduce inflammation, and protect skin cells from UV-induced damage.

NewsWorld-first discovery of noma-linked bacteria opens path to early diagnosis and prevention
Researchers have identified a bacterium strongly associated with noma disease, marking a major step towards earlier diagnosis and more effective treatment. They uncovered a previously undescribed species of Treponema bacteria, which may be responsible for the disease.

NewsUnexpected potential bacterial symbiosis found in fungus that causes angular leaf spot
Scientists have uncovered an unexpected microbial relationship that could help explain differences in the severity of a major disease affecting common beans. The discovery sheds light on how the pathogen evolves and may point to new strategies.
