NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsTurning agricultural waste into smarter livestock nutrition tools - and an alternative to antibiotics
A new study has found that biochar made from agricultural waste such as chestnut shells and vine prunings could help deliver beneficial compounds more effectively in animal feed, offering a promising alternative to antibiotics in livestock production.

NewsLemongrass essential oil may target bacteria even more effectively than conventional antibiotics, research suggests
Lemongrass essential oil can be even more effective than traditional antibiotics against some Streptococcus bacteria under certain conditions, new research to be presented at MLSFF26 has found.

NewsSurface treatment of wood may keep harmful bacteria at bay
A recent study suggests that bacteria thrive more readily on untreated than treated wood surfaces. The finding has implications for hygiene in both homes and public spaces.

NewsLow-cost preventive measures could mitigate spread of bacteria causing neonatal mortality
A new study found that a multifaceted infection prevention and control intervention could at least temporarily thwart outbreaks of infections from the Klebsiella pneumoniae bacterium.

NewsFrom microbial processes to biofilm control: our interview with JAM Microbial Biotechnology lead editor Manuel Simões
Professor Manuel Simões, Deputy Editor of the Journal of Applied Microbiology, has just been appointed as the journal’s new lead editor in Microbial Biotechnology. Here’s why he’s looking forward to the challenge.

NewsAntibiotic resistance can vary depending on where the bacteria live
Antibiotic susceptibility in resistant bacteria is not static. New research shows that bacteria harbouring resistance genes may respond differently to antibiotics if they are tested under conditions other than those used in standard laboratory assays.

NewsTiny vesicles, big risk: Environmental sweeteners trigger antibiotic resistance transfer
A new study reveals that mixtures of artificial sweeteners can stimulate soil bacteria to release microscopic extracellular vesicles that carry antibiotic resistance genes (ARGs).

NewsOne Health antimicrobial resistance modelling: from science to policy
Researchers have identified fundamental gaps in current mathematical modelling approaches that prevent translation of science into policy, including data limitations, knowledge gaps about AMU-AMR relationships, and the absence of international coordination mechanisms similar to climate change efforts.

News Thermo Fisher Scientific launches new color-based culture media to help detect Candida infections faster
Thermo Fisher Scientific today announced the launch of Thermo Scientific™ Brilliance™ Candida 2 Agar and Spectra™ Candida Agar, new color-based (chromogenic) culture media to help laboratories quickly detect and differentiate clinically important Candida species.

NewsDiisobutyl phthalate at environmental concentration promotes conjugative transfer of antibiotic resistance genes
Researchers investigating the ecological safety risks posed by dibutyl phthalate (DBP), in aquatic environments found it significantly increased conjugative transfer frequency in both intragenus (E. coli DH5α to E. coli HB101) and intergenus (E. coli DH5α to B. subtilis WB100N) systems.

NewsNanoplastics can interact with Salmonella to affect food safety, study shows
Researchers investigating what happens when nanoplastics (polystyrene) interact with Salmonella discovered an increased expression of virulence-related genes. The bacteria also formed thicker biofilms, which indicates they are becoming more virulent.

NewsFe₃O₄@mPEG-Ag nanoparticles: a new frontier in combating antibiotic resistance
A collaborative study introduces Fe₃O₄@mPEG-Ag nanoparticles (NPs) as a groundbreaking non-antibiotic strategy to combat drug-resistant bacteria, offering the antibacterial properties of silver (Ag) with the stability and biocompatibility of magnetite (Fe₃O₄) modified by methoxy poly(ethylene glycol) (mPEG).

NewsNew research highlights how biofilms could influence astronaut health, drug delivery and space agriculture
A global team of scientists has identified an often-overlooked biological system — biofilms — as a critical factor in the future of human space exploration.The team examines how biofilms could pose risks to astronaut health while also serving as powerful tools to sustain life beyond Earth.

NewsScientists uncover mechanism used by three bacteria-killing viruses to target transporter
Biochemists have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria use to build their chain-mail-like cell wall. Using advanced tools, the scientists have determined the common mechanism used by three different bacteria-killing viruses to block MurJ from doing its job.

NewsNovel camel antimicrobial peptides show promise against drug-resistant bacteria
Researchers have identified three novel antimicrobial peptides (AMPs) from dromedary camels that effectively target multidrug-resistant bacteria, offering potential alternatives to conventional drugs.

NewsElevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results continue to show high levels of E. coli and S. aureus, including antibiotic-resistant MRSA.

NewsScientists home in on Acinetobacter baumannii’s resistance evolution
Scientists have found a way to understand how Acinetobacter baumannii is evolving - and how best to strategize a fight against it. They have produced a huge whole-genome look at the rise of this resistance, pointing the way to new strategies in staying ahead of the pathogen.

NewsAntimicrobial resistance in foodborne bacteria remains a public health concern in Europe
Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from EFSA and ECDC.

NewsBacteria frozen in ancient underground ice cave found to be resistant against 10 modern antibiotics
Researchers tested antibiotic resistance profiles of a bacterial strain that until recently was hidden in a 5,000-year-old layer of ice of an underground ice cave – and found it could be an opportunity for developing new strategies to prevent the rise of antibiotic resistance.
