NewsFood scientists develop new antimicrobial for cleaning and sanitizing dry-food processing equipment
New research describes a novel chemical mixture for sanitation in low-moisture environments. Scientists found that a formulation containing cyclomethicone combined with vinegar-based acetic acid was the most effective against Salmonella and Cronobacter bacteria.

NewsMulti-strain probiotic therapy shows promise in preventing bacterial vaginosis recurrence
A global team of experts has identified a promising new approach to prevent recurrence of bacterial vaginosis (BV). In a phase 1 randomized clinical trial, researchers found that a short course of a multi-strain probiotic restored protective bacteria to the vagina, significantly reducing disease recurrence.

NewsStudy shows breath test can confirm bacterial infection
A study shows how molecules that are only broken down by infecting bacteria, and not by gut bacteria, can be used to confirm infection. By enriching these molecules with a naturally occurring carbon isotope, the researchers found that carbon dioxide produced when they break down is easily detected in a breath test.

NewsTarget behind cancer drug shown to help fight influenza in mice
A protein already targeted by FDA-approved cancer drugs may also help the body fight influenza. A study found that Programmed Death-Ligand 1 (PD-L1), best known for helping tumors evade immune attack, instead helped immunocompromised mice clear flu-infected lung cells and survive infection.

NewsBird flu risk to Danish cattle – new tool can warn farmers before infection spreads
Researchers have developed a tool that can predict where and when the risk of infection is highest. The tool is based on infection data from the U.S. outbreaks and adapted to a Danish context.

NewsScientists uncover how HPV-positive cancers hide from the immune system — and how to make them visible again
A new study solves a major mystery in cancer immunology by uncovering how HPV hides cancer cells from the immune system by using MARCHF8 to destroy MHC-I, which serves as a warning flag for the immune system.

NewsNovel biosensing platform enables fingertip blood-based micro-volume t-cell immune monitoring
A new platform, known as Tip Optofluidic Immunoassay Interferon-Gamma Release Assay (TOI-IGRA), could revolutionize how people monitor their immune health. The platform allows for the precise quantification of pathogen-specific T-cell responses using a mere 15-25 μL of fingertip blood.

NewsPrototype breath tests spot bacterial infections in minutes
Researchers have adapted the long-used breath test for Helicobacter pylori, a bacterium that causes a common stomach infection, expanding the technology’s capabilities to detect a broader range of bacterial infections.

NewsA newly identified disease of corn and sorghum may be mistaken for iron deficiency
A newly identified bacterial disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem.

NewsScientists discover a bacterium that protects against long Covid
Scientists have discovered the key role played by a bacterium, Dolosigranulum pigrum, that is naturally present in the respiratory microbiome. When present in greater numbers, these bacteria are associated with a reduction in the persistence of symptoms characteristic of long Covid.

NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsNew single‑cell technique reveals how tuberculosis‑like bacteria alter human cells
Researchers have developed a new technique to measure the content of individual human cells infected with bacteria that model tuberculosis – and it is already revealing biological changes that conventional analysis would miss.

NewsStudy identifies causes of potato dry rot in Colorado
Researchers have identified multiple fungal species causing dry rot in Colorado. By analyzing structural and molecular features, plant pathologists identified four Fusarium species associated with potato dry rot – including one that hadn’t previously been found in the U.S.
-
NewsStudy maps how tuberculosis bacteria power themselves
A new study provides the first detailed 3D structure of a protein called EtfD, which the bacterium Mycobacterium tuberculosis uses to extract energy from lipids (fats), along with the first laboratory test capable of directly measuring its activity.

NewsClimate change is fueling disease outbreaks
Researchers analyzed the connection between a cyclone in Peru and a massive outbreak of dengue fever, a mosquito-borne viral disease that can cause fever, rash, and life-threatening symptoms like hemorrhage and shock. Their findings reveal that warmer, wetter weather linked to climate change is making disease epidemics more likely.

NewsLemongrass essential oil may target bacteria even more effectively than conventional antibiotics, research suggests
Lemongrass essential oil can be even more effective than traditional antibiotics against some Streptococcus bacteria under certain conditions, new research to be presented at MLSFF26 has found.

NewsWhat factors influence likelihood and severity of Ebola outbreaks?
Two new papers looked at factors that contribute to how Ebola outbreaks begin and how severe they become. This Q&A looks at how the results could inform public health interventions to prevent pathogen emergence or slow the spread of Ebola and other infectious diseases.

NewsTargeting two flu proteins sharply reduces airborne spread
A study in ferrets — which have remarkably similar respiratory systems to humans — suggests that immunity to two proteins in the H1N1 influenza virus sharply reduces transmission.

NewsTrial finds vitamin D supplements don’t reduce Covid severity but could reduce long COVID risk
In a large, randomized trial, researchers have found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes.

NewsMothers' exposure to microbes protect their newborn babies against infection
A study dives into new depths to explore why only some babies develop severe infection to common bacteria. The research revealed that the babies that became most severely ill from E. coli infections also had markedly lower levels of germ-fighting antibodies transferred from their mothers.
