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.

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.

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.

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.
-
NewsNext generation genetics technology developed to counter the rise of antibiotic resistance
The new Pro-Active Genetics (Pro-AG) tool called pPro-MobV is a second-generation technology that uses an approach similar to gene drives to disable drug resistance in populations of bacteria.

NewsResearchers discover that vaginal bacteria don’t always behave the same way
By analyzing vaginal microbiome data at unprecedented resolution, researchers have identified 25 distinct vaginal microbiome types and demonstrated that bacteria of the same species can differ substantially in their functional potential, thereby affecting how these microbes interact with the body.

NewsTeam finds E. coli, other pathogens in Potomac River after sewage spill
Following one of the largest sewage spills in U.S. history, researchers detected high levels of fecal-related bacteria and disease-causing pathogens in the Potomac River, raising urgent public health concerns and underscoring the risks posed by aging sewer infrastructure.

NewsResearchers on the cusp of a vaccine for a global health threat
Researchers are on the cusp of a new vaccine to prevent chikungunya, a global health threat which attacks human joint tissue. The team tested whether they could engineer E. coli to assemble biopolymer particles which displayed chikungunya antigens and performed as a vaccine.

NewsNew study reveals cyanobacteria may help spread antibiotic resistance in estuarine ecosystems
Scientists have discovered that cyanobacteria may play a major role in spreading antibiotic resistance genes in coastal environments. The findings highlight a previously overlooked link between natural nutrient cycling and the global challenge of antibiotic resistance.

NewsTaxiing through the gut: Formic acid in the microbiome
Scientists have found that the gut bacterium Blautia luti produces formic acid (formate) instead of carbon dioxide (CO₂) and hydrogen, with hydrogen bound to CO₂. In this case, formic acid is the electron taxi, allowing the energetically costly production of hydrogen to be bypassed.

NewsLarge-scale study analyses the impact of climate on Legionnaires’ disease in Catalonia
A study has analysed the relationship between climatic conditions, the presence of Legionella in water systems and cases of Legionnaires’ disease in Catalonia. The link between these different factors highlights the need to adapt prevention and surveillance strategies in the context of climate change.
-
NewsNew study reveals a minimalist bacterial defense that disrupts viral assembly
Researchers describe how a single protein named Rip1 recognizes bacteriophages, the viruses that infect bacteria, and cause infected bacteria to die prematurely, thereby ending the chain of transmission.
-
NewsA mint idea becomes a game changer for medical devices
Researchers have developed a high‑performance coating made from peppermint essential oil that can be applied to the surfaces of many commonly used medical devices, offering a safer way to protect patients from infection and inflammation.

NewsGreen chemistry: Friendly bacteria can unlock hidden metabolic pathways in plant cell cultures
Co-culturing plant cells with harmless bacteria can expand the diversity of obtainable plant-derived compounds for pharmaceuticals, cosmetics, and agrochemicals, a new study shows.

NewsSugar molecules point to a new weapon against drug-resistant bacteria
Researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognise a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.
