NewsGenotype-specific response to 144-week entecavir therapy for HBeAg-positive chronic hepatitis B
HBV genotype B demonstrates superior histological responses to ETV therapy compared with genotype C, supporting the clinical value of HBV genotyping for personalized CHB management. These findings highlight the importance of considering viral genotype when evaluating treatment outcomes.

NewsResearchers identify strategies for preventing the most infectious strains of S. aureus in the NICU
A new study has identified which strains of Staphylococcus aureus – commonly known as staph – are commonly transmitted in neonatal intensive care units and which specific strains are most likely to cause invasive and serious infections.

NewsResearchers rebuild microscopic circadian clock that can control genes
Researchers have solved how the circadian clocks within microscopic bacteria are able to precisely control when different genes are turned on and off during the 24-hour cycle.

NewsStudy reveals how chills develop and support the body’s defense against infection
Researchers in Japan have identified the neural mechanism behind chills and the instinct to increase body temperature during infection.

NewsScientists create ‘smart underwear’ to measure human flatulence
Scientists have created Smart Underwear, the first wearable device designed to measure human flatulence. The device helps scientists revisit long-standing assumptions about how often people actually fart. It also opens a new window into measuring gut microbial metabolism in everyday life.

NewsNew AI model improves accuracy of food contamination detection
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods often require specialized expertise and are time consuming — taking several days to a week.

NewsNew algorithm enhances microbiome biomarker discovery by integrating biological relationships
Researchers have developed a novel algorithm, Microbiome Elastic Feature Extraction (MEFE), that significantly improves the identification of microbiome biomarkers by incorporating phylogenetic, taxonomic, and functional relationships among microbes.

NewsDeep-sea microbes get unexpected energy boost
A study shows that sinking organic particles—known as marine snow—begin to leak dissolved carbon and nitrogen when they reach depths of 2–6 kilometres, presenting microbes in the surrounding seawater with nutrients. The leakage is caused by the intense hydrostatic pressure in the deep ocean.

NewsResearchers develop simple at-home tests for detecting cat and dog viruses
Researchers report improved lateral flow assays for at-home screening of cats and dogs. In tests on veterinary clinic samples, the assays demonstrated 100% sensitivity and reproducibility for both feline parvovirus and canine parvovirus.

NewsAccomplices in the spotlight: When the interaction between fungi and bacteria becomes a dangerous alliance
Researchers discover new co-infection strategies of Candida albicans and Enterococcus faecalis. Only some E. faecalis strains significantly increased cell damage when infected simultaneously with Candida albicans. These strains produced cytolysin, a toxin that perforates cell membranes and kills the cells.

NewsAntibiotic-resistant bacteria found in many healthy birthing mothers and their newborns
A recent study found gut bacteria resistant to common antibiotics in a sizable percentage of healthy birthing mothers and their newborns. In this study, 38% of bacterial strains resistant to ceftriaxone transmitted from mother to infant were E. coli.

NewsNew gut-brain discovery offers hope for treating ALS and dementia
Scientists have identified a link between gut bacteria and the deterioration of the brain in Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). The researchers discovered that certain bacterial sugars cause immune responses that kill cells—and how to prevent it.

News‘Hidden’ bugs in our gut appear key to good health, finds global study
A single group of bacteria has repeatedly shown up in high numbers in the gut microbiomes of healthy people. Scientists found the level of CAG-170 bacteria present was consistently higher in healthy people than those with diseases including inflammatory bowel disease, obesity and chronic fatigue syndrome.

NewsMicrobiomes interconnect on a planetary-scale, new study finds
Scientists reveal that microbes living in similar habitats are more alike than those simply inhabiting the same geographical region. By analysing tens of thousands of metagenomes, they found that while most microbes adapt to a specific ecosystem, generalists can thrive across very different habitats.

NewsNeonatal sepsis: using vaginal microbiota to improve predictions
Researchers have found that some identifiable microbial signatures in vaginal swab samples taken at delivery are associated with a risk of neonatal sepsis.

NewsTechnology transfer for Corallopyronin A successfully completed with Phyton Biotech
Phyton Biotech has successfully transferred the manufacturing process for the microbial production of Corallopyronin A (CorA). CorA is a novel anti-infective agent with the potential to address neglected tropical diseases.

NewsTexas-grown cabbage meets global tradition in kimchi research
Researchers are turning Texan produce into kimchi as part of a study that links fermentation science, food safety and new market opportunities for U.S. farmers. The research examines how Texas-grown cabbage and other leafy greens perform during kimchi fermentation.

NewsBee bandits: ecologists study mutualistic plant-pollinator-microbe interactions
Researchers studying nectar-robbing behavior in bumble bees suspect other organisms beyond plants and pollinators may be aiding and abetting pollinators in nectar-robbing behavior.

NewsObesity linked to one in 10 infection deaths globally
Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study. People with obesity face a 70% higher risk of hospitalisation or death from an infection than those of a healthy weight.

News Engineered moths could replace mice in research into “one of the biggest threats to human health”
Scientists have created the world’s first genetically engineered wax moths – a development which could both accelerate the fight against antimicrobial resistance (AMR) and significantly reduce the need for mice and rats in infection research.
