NewsNew study sheds light on how bacteria ‘vaccinate’ themselves with genetic material from dormant viruses
Scientists have gained understanding on how bacteria defend themselves from phages, through gaining “memories” from predecessor dormant phages. The study will inform new phage therapies for bacterial infections that confer resistance to antibiotics.

NewsBartonella and babesia found in brain tissue of child with seizures
In a new case study, researchers have found Bartonella henselae, Babesia odocoilei and Babesia divergens-like MO-1 DNA in brain tissue samples from a young child with seizures and suspected Rasmussen’s encephalitis.

NewsA high-fat diet may impair response to infection
A new study in The Journal of Immunology reveals how a high-fat diet may impair the immune system’s ability to respond to infection by impacting the function of neutrophils, one of the first immune cells to respond to bacteria or viruses. The study demonstrated that male mice fed a high-fat ...

NewsNew model predicts how bacteria navigate obstacles to spread
A scientist has developed the first analytical model for predicting how bacteria spread in environments filled with obstacles. This model will help inform strategies for curbing bacterial infections or for designing better drug delivery.

NewsFrom pollution to polymer: Methane-munching microbe brews biodegradable plastic at high speed
Scientists have tapped into a methane-consuming bacterium, Methylocystis suflitae, to produce biodegradable plastics called polyhydroxyalkanoates (PHAs), offering a dual win for climate and sustainability.

NewsGatekeeping barriers manage communications between plants and bacteria
For over a century, the Casparian strip has been known as the root’s doorman, controlling what enters the plant. But a new study reveals it has a second job: regulating the delicate metabolic trade between plants and bacteria.

NewsTuberculosis in children and adolescents: EU/EEA observes a rise in 2023
The notification rate of tuberculosis (TB) went up from 2 to 2.5 per 100,000 population. But overall, numbers of notified paediatric cases remain relatively low across the region.

NewsHost’s sex plays key role in how gut microbiome evolves with age
Researchers studied how aging affects gut bacteria in a special group of rats generated to have genetic diversity similar to humans. Their research found that both biological sex and mitochondrial DNA—the small set of genes inherited only from mothers—play a key role in how gut bacteria change over time.

NewsFDA-approved dialysis drug may help fight against antimicrobial resistance
In account of the imminent threat of antimicrobial resistance (AMR), a study revealed that the FDA-approved sevelamer, which is used to treat chronic kidney disease undergoing dialysis, is successful in the removal of other off-target antibiotics (vancomycin and daptomycin) from the gut.
