NewsStudy sheds light on increased rates of severe human infections caused by Streptococcus subspecies
An increase in rates of severe invasive infections becoming resistant to key antibiotics has a team of infectious disease researchers studying a recently emerged strain of bacteria called Streptococcus dysgalactiae subspecies equisimilis (SDSE).

NewsTrial of rectal microbicide for HIV prevention begins in US
A clinical trial has launched to examine the safety and acceptability of a novel rectal HIV microbicide douche containing the antiretroviral drug tenofovir.

NewsHistones show promise against bacterial infections
Scientists have outlined that human histones have antimicrobial activity against different bacteria, including biofilms of Pseudomonas aeruginosa, one of the six most resistant bacteria in the world.

NewsExperts recommend considering dietary factors in probiotics and prebiotics research
A new Perspective paper finds that, while diet is a major determinant of gut microbiome composition and function, it has rarely been incorporated as a variable in research on the efficacy of probiotics and prebiotics.

NewsAI tackles huge problem of antimicrobial resistance in intensive care
Artificial intelligence (AI) can provide same-day assessments of antimicrobial resistance for patients in intensive care – critical to preventing life-threatening sepsis.

NewsInfant gut microbiota development predicts future health
Infants’ gut microbiota development follows one of five predictable trajectories, significantly influenced by infant exposures, according to a new study. These are strong indicators of later health outcomes, including allergies, growth patterns, and infections.

NewsA lung pathogen’s dilemma: infect or resist antibiotics?
Research has uncovered how Pseudomonas aeruginosa manages the trade-off between colonizing and surviving during infection by switching between biofilm formation for antibiotic protection and a more mobile, “planktonic” state to spread and access nutrients.

NewsBeneficial gut microbe has surprising metabolic capabilities
To address childhood malnutrition — which affects 200 million children globally — researchers at Washington University School of Medicine in St. Louis developed a therapeutic food that nourishes the collections of beneficial microbes that reside in the gut, and improves children’s growth and other measures of their health. ...

NewsGut bacteria transfer genes to disable weapons of their competitors
New research shows how common gut bacteria tame their antagonistic neighbors by transferring genes that change their weapon systems.

NewsBacteria and fungi found on bat wings that could help fight deadly white-nose syndrome
Bacteria and fungi from the wings of bats could play a significant role in saving them from white-nose syndrome (WNS), a fungal disease affecting the skin of wings and muzzle, which has nearly wiped out vulnerable bat populations across North America.

NewsA metabolic secret of ethane-consuming archaea unraveled
Scientists have presented a study on the degradation of ethane, the second most abundant alkane in seeps on the deep seafloor. They characterized enzymes involved in the process and found that their reaction breaks an established dogma in the field of anaerobic biochemistry.

NewsLyme borreliosis: New approach for developing targeted therapy
A research team has made significant progress in understanding the mechanism of Lyme borreliosis infection and identified a potential way forward for the development of targeted therapies that do not rely on antibiotics.

NewsUnnoticeable electric currents could reduce skin infections
Using a few zaps of electricity to the skin, researchers can stop bacterial infections without using any drugs. For the first time, researchers have designed a skin patch that uses imperceptible electric currents to control microbes.

NewsAntibiotics and antifungals may slightly affect Parkinson’s risk, study finds
A study has found that people who took multiple courses of penicillin antibiotics had a modestly lower risk of developing Parkinson’s disease, a surprising finding that researchers say highlights the complex relationship between bacteria in the digestive tract and brain health.

NewsNative fungus could offer biocontrol for invasive autumn olive
Researchers are studying a native fungus that potentially could kill the invasive autumn olive with minimal human interaction.To remove the autumn olive currently, the plant needs to have its underground root system removed in addition to the destruction of the plant itself, but this fungus could make this process much easier.

NewsStudy yields evidence of oldest confirmed photosymbiosis in corals
Researchers have demonstrated, using nitrogen isotope analyses, that some extinct corals from the Middle Devonian period were already symbiotic. This represents geochemical evidence of the oldest confirmed photosymbiosis in corals.

NewsMaternal antibodies interfere with malaria vaccine responses
Maternal antibodies passed across the placenta can interfere with the response to the malaria vaccine, which would explain its lower efficacy in infants under five months of age, according to research.

NewsNew tool enables a more complete and rapid decoding of the language of algal gene expression
A new method that research teams can use to measure and compare different forms of proteins and protein complexes helped reveal a previously unseen molecular signature of how algal genomes are controlled during the cell cycle.

NewsRepeated COVID vaccines enhance mucosal immunity against the virus
New work has found that repeated Covid-19 vaccinations lead to the presence of mucosal antibodies, for example, inside the nose.
