NewsResearch alert: Bacterial chatter slows wound healing
Researchers have discovered a previously unrecognized mechanism by which Staphylococcus aureus delays wound healing. The study finds that quorum sensing is a key driver of delayed healing in wounds infected by S. aureus.

OpinionCould livestock-originated probiotics replace synthetic antibiotics for livestock?
In many developing countries, the use of antibiotics in both humans and animals is often indiscriminate and poorly regulated. Could livestock-originated probiotics be a suitable replacement?

NewsResearchers discover method to combat antibiotic treatment failure
Researchers explored ways to alter our own immune cells to help antibiotics work more effectively. They identified a small molecule that alters the body’s immune cells, forcing them to ’wake up’ dormant bacteria and make them more vulnerable to antibiotic treatment.

News‘Cocktails’ of common pharmaceuticals in our waterways may promote antibiotic resistance
New research has shown, for the first time, how mixtures of commonly used medications which end up in our waterways and natural environments might increase the development of antibiotic resistant bacteria.

NewsRoot chemistry determines how antibiotic resistance spreads from manure to crops
Researchers found that the rhizosphere, the narrow soil zone surrounding plant roots, is a major hotspot for the accumulation of manure-derived ARGs. Across eight common crops, ARG abundance in rhizosphere soil was on average 1.24 times higher than in bulk soil.

NewsFreshwater snails are an overlooked reservoir of AMR, study reveals
Freshwater snails across Africa and the UK carry bacteria containing a wide range of antimicrobial resistance (AMR) genes, including those predicted to confer resistance against last-resort antibiotics, according to a new study led by AMI members.

NewsWHO warns of widespread resistance to common antibiotics worldwide
One in six laboratory-confirmed bacterial infections causing common infections in people worldwide in 2023 were resistant to antibiotic treatments, according to a new World Health Organization (WHO) report.

NewsScientists develop safer and more sustainable antimicrobials to prevent infection of cow udders
A new study has unveiled an alternative class of potent antimicrobial compounds that could be used in the agriculture industry to combat multi-drug-resistant bacteria that cause bovine mastitis.

NewsSummer studentship: Shen explores how a novel peptide can destabilise the outer membrane of E. coli
Li Shen reports back on his AMI-sponsored summer studentship which investigated a novel antibiotic adjuvant at the Centre for Bacterial Resistance Biology, Imperial College London.

NewsScientists uncover molecular mechanisms for bacterial lipid transport
Researchers have successfully applied cryo-electron microscopy (cryo-EM) to unveil the molecular structures of critical protein machines that transport lipids and maintain the outer membrane (OM) barrier of Gram-negative bacteria.

NewsPeptide study paves path toward new weapon against antibiotic-resistant bacteria
New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more vulnerable.

NewsPathogenic yeast strains found in urban air but not along the coast
A pilot study has found that urban air contained pathogenic strains of Candida yeast that were absent in coastal air samples, revealing a potential transmission method.

News‘Alarming’ rise in newborn babies with antibiotic-resistant infections, researchers find
Researchers are calling for an urgent overhaul of diagnostic and treatment guidelines for infections in newborn babies, after a study revealed frontline treatments for sepsis are no longer effective to treat the majority of bacterial infections.
-
NewsDeadly pathogens found in commercial raw cat foods
An analysis of commercial raw cat foods detected disease-causing microbes, including some that are resistant to antibiotics, creating risks for both pets and their owners, according to a new study.
-
NewsSuper-resistant bacteria found in wild birds at a rehabilitation center in Brazil
Researchers have found antibiotic-resistant bacterial clones in wild birds at a rehabilitation center. The identified Escherichia coli clones have been found in community- and hospital-acquired human infections worldwide, and were present in the intestinal tracts of a vulture and an owl.

NewsGenetic culprits IDed in capture of 100 years of antibiotic resistance evolution
The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution.

NewsVast gut microbiome diversity and antibiotic resistome across 14 mammal species on the Tibetan Plateau
A new study provides the most comprehensive genomic catalogue to date of mammalian gut microbiomes from the Tibetan Plateau.
-
NewsReview shows around one in three hospital infections involve antimicrobial resistance
With an estimated 1.14 million deaths worldwide annually caused by bacteria becoming resistant to antibiotics, a study shows that in hospital settings antimicrobial resistance is common and independently associated with a higher risk of death.

NewsScientists develop a virus cocktail to combat superbugs
Researchers have developed a bespoke phage therapy, Entelli-02, a five-phage cocktail designed specifically to target Enterobacter cloacae complex (ECC), a group of bacteria responsible for severe, often difficult-to-treat infections.
