NewsImmune system keeps mucosal fungi in check
Researchers investigating the mechanisms that keep the fungus under control on our mucosa shed light on how homeostasis is maintained through the fine-tuned interplay between Candida albicans and the epithelial barrier on the one hand, and the immune system on the other hand.

NewsStreptococcus suis serotype 2 collagenase-like protease promotes meningitis by increasing blood-brain barrier permeability
Streptococcus suis serotype 2 (SS2) is an emerging zoonotic pathogen that causes meningitis in humans and pigs. Researchers have investigated the role and mechanism of the SS2 Clp in promoting the passage of the bacterium across the blood-brain barrier (BBB).

NewsHarmless Klebsiella strain shows powerful protection against gut infections in Inflammatory Bowel Disease (IBD) model
A new study demonstrates that a harmless strain of Klebsiella can eliminate infections and reduce gut inflammation in mouse models of inflammatory bowel disease (IBD).

NewsSwedish freshwater bacteria give new insights into bacterial evolution
Researchers analyzing the DNA of all known Caulobacterales species, including newly collected samples from Swedish and Finnish forest lakes, discovered that several freshwater species lacked more than a hundred genes typically linked to the group’s complex lifecycle.

NewsFecal tests reveal active termite attacks
Termite pellets can linger long after the insects that dropped them have disappeared. By testing for microbes in the excrement, researchers can distinguish old droppings from fresh, and whether a colony is actively chewing its way through a home.

NewsStudy links gut bacteria to bloodstream infections in newborns within sub-Saharan Africa for the first time
New research has shown gut and bloodstream infections are caused by the same bacteria giving hope of better prevention and diagnosis of deadly neonatal sepsis.

NewsCould hidden infections be fueling long COVID?
For millions suffering from long COVID, their persistent breathlessness, brain fog and fatigue remain a maddening mystery, but microbiologists think they may have cracked the case. The review argues that co-infections acquired before or during COVID could cause symptoms to persist indefinitely for many people.

NewsEngineering oncolytic bacteria as precision cancer therapeutics
A new review summarizes recent advances in the design and application of synthetic biological strategies that enhance bacterial precision, safety, and efficacy in tumor therapy.

NewsApplications of AI in antimicrobial resistance prevention and control
Researchers have published a review shedding light on how AI is revolutionizing the prevention and control of AMR. The article illustrates how machine learning and deep learning are transforming surveillance, diagnosis, treatment optimization, and drug discovery.

NewsUnique bond identified as key to viral infection speed
Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research reveals a deliberate imbalance in their shape that helps them infect their hosts.
-
NewsResearchers discover how Ebola and Marburg disrupt the gastrointestinal tract
A new study sheds light on the mechanisms behind the damage caused by Ebola (EBOV) and Marburg virus (MARV) to the gastrointenstinal tract. TIt found that both viruses are capable of infecting and replicating within human gut epithelial cells and that the viruses interfere with the cells’ ability to regulate fluid secretion, mirroring the severe symptoms observed in patients.

NewsPandemic ‘beneath the surface’ has been quietly wiping out sea urchins around the world
Over the last four years, an unrecognized pandemic that has been wiping out sea urchins around the world has hit the Canary Islands. The consequences on marine ecosystems aren’t yet fully known, but likely profound.

NewsStudy shows why mRNA-based COVID-19 vaccines can cause myocarditis
Investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents — and they’ve shown a possible route to reducing its likelihood.

NewsOlder age, chronic kidney disease and cerebrovascular disease linked with increased risk for paralysis and death after West Nile virus infection
Older people with a history of chronic kidney disease or conditions affecting blood flow to the brain such as stroke face about double the risk for developing neuroinvasive disease that can lead to paralysis and death following infection with West Nile virus, new research finds.

NewsIn pneumonia’s tug-of-war, lung microbiome could tip the balance
Scientists have found the lungs’ own microbial community, or microbiome, appears to influence how pneumonia evolves, who responds well to treatment and whether a patient will recover successfully or continue to deteriorate.
-
NewsNew 15-minute hepatitis C test paves the way for same-day treatment
Scientists have developed the fastest test yet for diagnosing hepatitis C virus (HCV). The highly accurate diagnostic delivers results to patients in just 15 minutes - crucial for kickstarting patients’ treatment before they leave their appointment.
-
NewsOpioid use linked to higher risk of C. difficile infection
New research from the University of Georgia suggests that opioid use could make patients more vulnerable to infections. The meta-analysis examined four studies of almost 120,000 patients. The researchers found that about 31% of patients who were prescribed and taking opioids caught C. diff, compared to 17% of patients who weren’t using them.

NewsCloves and miswak: Antimicrobial effects of Syzygium aromaticum and Salvadora persica against common pathogens in vitro
Clove essential oil (CEO) derived from Syzygium aromaticum and miswak (Salvadora persica) contains bioactive compounds with antimicrobial properties. This study aimed to evaluate the in vitro antimicrobial efficacy of CEO, miswak, and their combination against key peri-implantitis pathogens.

NewsStudy reveals promising gut-targeted therapy for C. difficile infections
Researchers have uncovered how the body’s bile acids bind to block C. diff’s most dangerous toxin. The research has informed the development of a new compound that can protect against C. diff in preclinical models, offering hope for safer, more effective treatments.

NewsRice resists change: Study reveals viral tools for probing gene function fall short
Researchers tested two popular viral vectors - barley stripe mosaic virus (BSMV) and foxtail mosaic virus (FoMV) - to see if they could temporarily switch genes on or off in rice (Oryza sativa). They found no evidence that these virus-enabled reverse genetics (VERG) techniques work in rice.
