NewsScientists collect ‘microbial fingerprints’ found in household plumbing
Scientists sampled faucets in eight homes for seven days to see the flow and change of different bacteria populations. They found that, though houses generally shared major categories of bacteria, down to the species level, there was wide variation from house to house.

NewsDiverse phage populations coexist on single strains of gut bacteria
A new study shows that a single bacterial species, the host of a phage, can maintain a diverse community of competing phage species. Several phage species coexist stably on a population of a genetically uniform strain of E. coli.

NewsUrgent need for integrated detection strategies for AMR in water environments
A new review calls attention to the urgent need for integrated detection strategies that combine the precision of molecular tools with the cost-effectiveness of traditional methods which could enable more efficient, accessible, and scalable AMR monitoring.

NewsA new class of antivirals could help prevent future pandemics
A new study introduces a proof-of-concept for a novel class of antivirals that would target a type of enzyme essential not just to SARS, but also many RNA viruses, including Ebola and dengue, as well as cytosolic-replicating DNA viruses, including Pox viruses.

NewsFirst full characterization of kidney microbiome unlocks potential to prevent kidney stones
Low levels of bacteria like E. coli and Lactobacillus in our urine come from communities in our kidneys, where they promote or prevent kidney stone formation.

NewsNew study highlights rise in severe Shigella infections among homeless patients in Vancouver
A recent study has uncovered an increase in severe multidrug-resistant (MDR) Shigella sonnei infections, particularly among people experiencing homelessness (PEH) in Vancouver, Canada.

NewsHow a middle schooler found a new compound in goose feces
Middle schoolers through a partnership with a local univeristy, collected and analyzed environmental samples to find new antibiotic candidates. One unique sample, goose feces collected at a local park, had a bacterium that showed antibiotic activity.

NewsPeat-bog fungi produce substances that kill tuberculosis-causing bacteria
An analysis of fungi collected from peat bogs has identified several species that produce substances toxic to the bacterium that causes the human disease tuberculosis.

NewsCold plasma isn’t just for sterilisation - it could become a vital green tool in water purification
Cold plasma isn’t just for sterilisation, but offers potential as a sustainable water treatment that can target stubborn contaminants like biofilms and pharmaceuticals, according to a new review.

NewsBacteria ditch tags to dodge antibiotics
Bacteria modify their ribosomes when exposed to widely used antibiotics, according to new research. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance.

NewsNanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry
A tiny, four-fingered ‘hand’ folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them.

NewsNewly designed nanomaterial shows promise as antimicrobial agent
Newly developed nanocrystals show potential as antimicrobial agents that are stable, effective and easy to produce.

NewsAntibiotics from bacteria could counter biotic stress in crops, replacing synthetic chemicals
Actinomycetes-derived antibiotics and other metabolites could be deployed to mitigate biotic stress in crops, potentially replacing synthetic chemicals as chemo-control agents against phytopathogens, a new review suggests.

NewsResearchers develop a simple lab-free test to detect bacteria in fluids from water to urine
A novel new test for bacteria in fluids makes it as easy as observing a colour change to confirm the presence of disease-causing pathogens, promising much easier diagnostic tests and greater food safety.

NewsUsing antibiotics alone to treat children with appendicitis is a cost-effective and safe alternative to surgery
An analysis of data from more than 1,000 children with uncomplicated acute appendicitis found an antibiotics-only approach resulted in less pain and fewer days off from school during the first year after the initial hospital visit.

NewsA new tool to predict the most effective phage cocktail
Researchers have developed a simple and effective new tool that recommends the best possible phage cocktail for a given patient. Paving the way for personalized phage therapies to treat antibiotic-resistant bacterial infections.

NewsPandrug-resistant bacteria from the war in Ukraine are extremely pathogenic
Using samples from 141 war-wounded it was shown that several bacteria types were resistant to broad-spectrum antibiotics and that six per cent of samples were resistant to all antibiotics that the researchers tested.

NewsAntibiotics initiated for suspected community-acquired pneumonia even when chest radiography results are negative
A new study shows that many general practitioners prescribe antibiotics for suspected community-acquired pneumonia even when chest X-ray results are negative, highlighting a gap between guidelines and actual practice.

NewsScientists uncover new mechanism in bacterial DNA enzyme opening pathways for antibiotic development
Researchers have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic target. This enzyme, present in bacteria but absent in humans, plays a crucial role in supercoiling DNA, a necessary process for bacterial survival.
