NewsComparing veterinary antimicrobial stewardship: Why Brazil needs stronger monitoring systems
A new comparative analysis reveals critical gaps in antimicrobial monitoring frameworks across three major economies, with significant implications for global public health and food security.

NewsA universal toolkit for editing bacterial DNA
A major collaboration involving nine labs has transferred a particularly useful DNA editing system from E. coli into 14 new species of bacteria, spanning three major branches of the bacterial family tree.
-
NewsGene-sharing myth challenged as bacteria shown to police DNA exchange
A new study reveals that bacteria can actively limit the spread of antibiotic resistance genes, using a newly characterized mechanism that blocks DNA transfer between cells. It focuses on how bacteria exchange genetic material through tiny intercellular bridges known as nanotubes.

NewsCinnamic acid blocks plasmid conjugation to slow antibiotic resistance spread
A new study reveals that cinnamic acid, a widely used food additive found in cinnamon, can effectively inhibit plasmid‑mediated conjugation, a major route for the global spread of antibiotic resistance genes (ARGs).
-
NewsResearchers disable antimicrobial resistance in cystic fibrosis-associated bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.

CareersQ&A: Meet Letters in Applied Microbiology junior editor Daniel Jesuwenu Ajose
We caught up with Daniel Jesuwenu Ajose, a Postdoctoral Research Fellow at the School of Biology and Environmental Sciences, University of Mpumalanga in South Africa, who is one of the newest Junior Editors with Letters in Applied Microbiology

NewsViruses enhance sulfamethoxazole removal in wetlands by modulating bacteria-phage interactions
A new study examines the role of viruses in sulfamethoxazole (SMX) removal in constructed wetlands. The research demonstrates that the addition of phage-concentrated solutions (PCS) enhances the degradation of SMX by enriching SMX-degrading bacteria.

NewsWHO-recommended antibiotics cover only 1 in 4 neonatal sepsis infections in low- and middle-income countries
A major multi-country study has found that WHO-recommended first-line antibiotics for neonatal sepsis are likely to be effective in only one quarter of infections in low- and middle-income countries (LMICs).

NewsAntibiotic resistance genes found in newborns within hours of birth, study shows
Antibiotic resistance genes can be present in newborns within the first hours of life. The study analysed meconium samples from 105 infants admitted to a neonatal intensive care unit (NICU) within the first 72 hours of life between July 2024 and July 2025.

NewsGraphitized biochar rewires soil microbes to accelerate pollutant breakdown in rice paddies
A new study reveals that a specially engineered form of biochar can dramatically enhance the natural ability of soil microbes to break down pollutants in rice paddies, offering a promising strategy for cleaner and more sustainable agriculture.

NewsStandard-dose antibiotic the ‘preferred choice’ of treatment for uncomplicated acute sinusitis
A study of patients with acute sinusitis found no major differences in measured outcomes between adults who received standard amoxicillin and amoxicillin‑clavulanate. Patients treated with amoxicillin‑clavulanate were at slightly higher risk of contracting secondary infections.
-
NewsStudy finds blood pressure drug effective for treating antibiotic-resistant bacteria
A new study reports that a drug used to lower blood pressure could also be the basis of a promising new treatment for methicillin-resistant Staphylococcus aureus (MRSA). Candesartan cilexetil not only killed MRSA bacteria at different growth stages, but also reduced the formation of biofilms.
-
NewsAncient viruses serving as gene delivery couriers to help bacteria resist antibiotics
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).
-
NewsFoxes and birds could be ‘early warning system’ to survey spread of antibiotic resistance into ecosystems
Wildlife monitoring could alert us to the spread of highly antibiotic resistant bacteria into unexposed ecosystems, highlighting a potential public health strategy.
-
NewsGlobal strategy to combat drug‑resistant fungi is about to change
An increasing number of fungi are becoming resistant to medication, posing serious risks for patients with weakened immune systems. That is why fifty researchers from around the world are calling for action against drug‑resistant fungi.

NewsScientists discover the antibacterial potential of ‘hero’ Korean skincare ingredient
Fans of Korean skincare may be familiar with ‘hero ingredient’ Madecassic acid for its skin-soothing properties, but researchers have revealed its greater potential for use in the battle against antibiotic resistance.

NewsBelfast to host global scientists at the Microbiology Society’s Annual Conference 2026
Baroness Natalie Bennett will join leading scientists and policymakers in Belfast for a discussion on how to slow the spread of superbugs at the Microbiology Society’s Annual Conference.
-
OpinionWhy chromogenic media matters when testing for invasive pathogens: Could the cheapest plate be an expensive decision?
Chris Armstrong, President of Microbiology, Thermo Fisher Scientific, argues that laboratories should stop judging fungal culture media on unit price alone.

NewsUnlocking how dogs’ fungal ear infections evade treatment points vets to drug stewardship
Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists found in a new study.
