NewsGut bacterium impairs liver cancer treatment, inducing immunotherapy resistance
Researchers discovered that transplanting the gut bacterium Phocaeicola vulgatus into mouse models of liver cancer induced immunotherapy resistance. The finding is consistent with clinical observations in patients, showing that patients with low levels of P. vulgatus responded better to treatment.

NewsManure digesters on farms carry limited benefits and potential harms
Manure digesters, touted as eco-friendly solutions for managing agricultural waste and reducing greenhouse gases, have limited capacity to reduce livestock-related greenhouse gas emissions, and entail potential hazards that may outweigh their benefits.

News$3.7 million awarded for research into sand flies, vectors of parasitic disease leishmaniasis
Professor Gideon Wasserberg at UNC Greensboro has been awarded a prestigious $3.7 million National Institutes of Health R01 grant to advance his research on controlling sand flies, the vectors of the parasitic disease leishmaniasis.

NewsPhase 2 clinical trial results show potential to shorten TB treatment time
New clinical trial results show that the novel antibiotic candidate sorfequiline (TBAJ-876), a next-generation diarylquinoline, has the potential to improve tuberculosis (TB) treatment when combined with pretomanid and linezolid in a treatment regimen known as “SPaL.”

NewsResearchers expand virus-based treatment options for antibiotic-resistant infections
Phages are extremely specific about which strains of a bacterial species they will attack. This has limited their effectiveness against the most antibiotic-resistant strains. To overcome this problem, the research team “trained” the phages by allowing them to evolve together with the bacteria in a controlled laboratory setting for 30 days.

NewsDid US cities’ indoor vaccine mandates affect COVID-19 vaccination rates and outcomes?
New research reveals that despite widespread adoption of indoor vaccine mandates in major US cities during the COVID-19 pandemic, there is no consistent evidence that these policies significantly increased vaccination rates or reduced COVID-19–related outcomes. The findings contrast with those from other countries, as national mandates abroad boosted vaccine uptake.

NewsA microbial blueprint for climate-smart cows
Recent research has shown that feeding cows red seaweed can dramatically cut the amount of methane that is produced and released into the environment. A new study sheds light on that process and reveals which microbes in the cow’s gut might help reduce methane.

NewsGreen chemistry for sustainable personal care
A recent review examined microbial biosurfactants as sustainable alternatives to synthetic surfactants in shampoo formulations. The authors addressed the growing demand for environmentally friendly and dermatologically safe cleansing agents, and emphasized the need to transition from petrochemical-based ingredients such as sodium lauryl sulfate (SLS) to biodegradable biosurfactants.

NewsVaccine skepticism on social media can predict public health crises
Researchers have developed a new approach that could help public health officials predict where outbreaks might occur. By analyzing social media posts, the method identifies early signs of increasing vaccine skepticism — a warning signal that could emerge before any disease begins to spread.

NewsMicropores pave the way for infection research
Organ-on-a-chip technology often contains gels that imitate the 3D environment of our tissues - however, many of these gels are too dense, hindering the passage of microbes and immune cells, and movement is essential to recreate how infections really develop. In this study, the research team developed a new type of porous gel that solves this problem.

NewsTime to act and not react: how can the European Union turn the tide of antimicrobial resistance?
Despite determined efforts by countries and healthcare professionals, Europe is not on track to meet four of the five AMR targets set by the EU Council for 2030*, according to data released on EAAD.

NewsApriori Bio and A*STAR Infectious Diseases Labs Announce strategic partnership to advance next generation influenza vaccines
Apriori Bio and the Agency for Science, Technology and Research Infectious Diseases Labs (A*STAR IDL) announced a strategic research partnership to co-develop and evaluate next generation self-amplifying RNA (saRNA) vaccines targeting seasonal and pandemic influenza.

NewsMedications change our gut microbiome in predictable ways
A study shows that many of the changes to the gut microbiome are driven by competition for nutrients – medications reduce certain bacterial populations and change the availability of nutrients, and the bacteria most able to capitalize on those changes are the ones to survive.

NewsWastewater from most countries favours non-resistant bacteria
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. By testing the potential of untreated municipal wastewater from 47 countries to select for resistant E. coli, researchers show that while some samples indeed do so, most instead suppress them.

NewsHepatitis E virus from rats can also infect humans in individual cases – a new zoonotic pathogen?
It has only been known for a few years that humans can also be infected with a variant of the hepatitis E virus that is usually prevalent in rats. Following reports of individual cases, mainly from Hong Kong and Spain, the first infection with ratHEV has now also been described in a patient from Germany.

NewsPig disease vaccine effectiveness linked to T cell response
A new study shows that the effectiveness of current vaccines against porcine reproductive and respiratory syndrome virus (PRRSV) is due to the response of T cells against the disease, rather than the production of antibodies. The work is an important step in identifying specific targets for vaccines on a rapidly mutating virus.

NewsSugar transporter discovery offers promising avenue for improving antibiotic efficacy
Scientists have recently demonstrated that aminoglycosides enter bacteria by using sugar transporters. They have also successfully doubled the number of transporters, even in the most resistant Escherichia coli strains, thus improving antibiotics’ penetration rate and efficacy.

NewsEmerging pollutants threaten efficiency of wastewater treatment: New review highlights urgent research needs
A new scientific review has shed light on how emerging pollutants commonly found in wastewater are disrupting biological phosphorus removal processes, posing risks to water quality and ecological health. The study examines how pharmaceuticals, microplastics, and industrial chemicals interfere with the key microorganisms responsible for phosphorus removal in wastewater treatment plants.
