NewsStudy reveals how bacteria assemble their envelope
Researchers have discovered a key process for how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently manifest resistance to antibiotics.
-
NewsResearch forecasts global antimicrobial resistance threats for the next two decades
New research has analysed antimicrobial resistance (AMR) on a global scale to predict how resistance patterns could evolve by the year 2050, identifying around 210 resistance traits that could pose the greatest future risk.

NewsNew antibiotic attacks bacteria in never-before-seen way
Scientists have discovered a new antibiotic that works in a never-before-seen way and may be the next frontliner in the fight against drug-resistant superbugs.

NewsThe evolution of individual species can shape entire species communities
A study demonstrated that the evolution of a single species can alter the composition of an entire species community. The study monitored a microbial community composed of 23 bacterial species for four years. Researchers analysed the community’s species composition and changes in bacterial genomes.

NewsQ&A: Meet Letters in Applied Microbiology Junior Reviewer Md. Ekramul Karim
We caught up with Md Ekramul Karim, a Ph.D. candidate at the University of Houston, who is one of the newest Junior Reviewers with Letters in Applied Microbiology.

NewsFrom pest to useful tool: How wax moth larvae can help reduce animal testing in research
A new study indicates greater wax moth larvae show great potential as a robust and ethically acceptable in vivo model for studying pathogenic bacteria.

NewsAntibiotics drive resistance in waterways - even after they break down
Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.

NewsShiga-producing E. coli infections are becoming more resistant to antibiotics
A new study indicates resistance to antimicrobial agents is rising among human infections with Shiga toxin–producing Escherichia coli bacteria.

NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.

NewsResearcher investigates how a bioengineered peptide can break through harmful bacterial ‘fortresses’ and curb severe infections
A researcher is refining a powerful therapy for drug-resistant bacteria that pierces the gooey coating that anchors and protects such germs from the drugs we take to kill them. She has found that an antimicrobial peptide naturally found in cows weakens the biofilm defenses of Klebsiella pneumoniae bacteria and destroys it.

NewsIron-modified biochar turns soil oxygen into a cleaner for antibiotic pollution
Antibiotic residues in agricultural soils are an emerging environmental concern, with potential impacts on soil health, crop safety, and the spread of antimicrobial resistance. A new study reports on an iron-modified biochar that helps soil use its own oxygen and iron chemistry to break down sulfamethoxazole.

NewsThe future of phage therapy will be decided by more than science alone
As antimicrobial resistance accelerates worldwide, leading experts gather in Valencia to address the scientific, regulatory, manufacturing and clinical challenges that will determine whether phage therapy becomes a routine healthcare solution.
-
NewsResearchers discover how to turn one germ’s drug resistance into an Achilles’ heel
As Mycobacterium tuberculosis mutates to protect itself from rifampicin, it also creates new weak points that other therapies could exploit. A new study shows that the most common rifampicin-resistance mutation slows bacterial RNA polymerase, creating vulnerabilities that future combination therapies may be able to target.

NewsGladstone launches Center for PhAIge Therapy to harness AI in the fight against drug-resistant infections
Gladstone Institutes has received funding to establish the Center for PhAIge Therapy, a research center that will develop new phage-based treatments for antibiotic-resistant bacterial infections. The five-year grant makes Gladstone one of three institutions across the country selected to lead this coordinated effort.

NewsZinc deficiency promotes fluconazole-resistant Candida auris virulence
Researchers identified key nutritional and genetic factors that drive the virulence of fluconazole-resistant Candida auris. Under zinc-deficient conditions, these drug-resistant strains gain a fitness advantage, exhibiting increased pathogenicity and resistance to macrophage-mediated killing.
-
NewsNew antibiotic design could help treat drug-resistant infections
A new study has shown that antibiotics can be chemically redesigned so they are less easily removed by efflux pumps. This allows the antibiotic to remain inside the bacterial cell at higher concentrations, restoring its ability to kill bacteria even when resistance mechanisms are present.
-
NewsScientists fight antimicrobial resistance by treating diseases with human antibodies
In a review, researchers highlight the promise of using human monoclonal antibodies (mAbs) to treat patients more effectively and tackle AMR. They say AMR needs to be addressed with multiple and differentiated strategies, and vaccines and mAbs are the most promising tools.
-
NewsResearchers investigate soil microbes from around the world for new antibacterial drugs
A team of researchers is looking to nature to find microbes that can be used to create new antibiotics to treat the growing threat of drug-resistant bacteria. They will screen soil microbes from around the world to hunt for sources of new antibacterial drugs.

NewsScientists make groundbreaking discovery – and find a possible new ally – in the opioid crisis
Scientists analyzed used hypodermic needles from a needle exchange program to better understand what narcotics actually were in the needles and determine if any non-viral pathogens were present.

NewsHospital wastewater reveals drug-resistant fungus strains months before patients show symptoms
A study reveals that sampling raw wastewater closer to the source — sewer lines that directly serve hospitals, retirement homes, and long-term care facilities — allows scientists to detect drug-resistant strains of Candida auris as many as five months before patients begin showing symptoms.
