NewsComparison of E. coli inactivation by UV222-ADPs and UV254-ADPs in water
A new study investigates advanced disinfection processes (ADPs) that use 222 and 254 nm far-ultraviolet radiation in conjunction with hydrogen peroxide (H2O2), sodium percarbonate (SPC), and persulfate (PDS) to inactivate E. coli in water.

NewsScientists research potential anti-ulcer vaccine targeting Helicobacter pylori
Scientists are on the way to finding a vaccine to fight off the Helicobacter pylori bacterium, possibly preventing stomach ulcers and lowering the risk for stomach cancer. They used immunoinformatics to scan its genetic makeup and predict which parts can trigger a strong immune response.

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.

NewsScientists reveal role of paeoniflorin in mediating microbiota-gut-brain axis
Paeoniflorin treatment significantly reduced depression-like behaviours in stressed rats, while gut microbiota analysis revealed that the treatment corrected imbalances in key metabolites associated with brain function, a study shows.

NewsCHIKVdb: A comprehensive genomic resource for chikungunya virus surveillance and outbreak response
Scientists have developed the Chikungunya Virus Database (CHIKVdb), a comprehensive genomic resource. CHIKVdb integrates 8,193 nucleotide sequences and 10,637 protein sequences from five major host categories across 99 countries, spanning 40 years.

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.

NewsTracking infectious disease spread via commuting pattern data
Researchers have introduced a Commuter Metapopulation Model (CMPM) to simulate the spread of COVID-19 with actual commuting data provided by the country’s second-largest telecommunication network, revealing it could better capture spatial variety in outbreak patterns.

NewsYeast survives Martian conditions, study shows
Life on Mars would have to contend with challenging conditions including shock waves from meteorite impacts and soil perchlorates. Scientists subjected Saccharomyces cerevisiae to these conditions, finding those that survived had assembled RNP condensates.

NewsWhen faucets rest: hidden microbial risks emerge in hours
Stagnant water in building plumbing systems is a well-known driver of microbial growth and contamination, including L. pneumophila. A new study highlights a short “microbial safety window” of 2–4 hours, after which risks increase significantly.
-
NewsData-guided bioelectrodes pave way for greener remediation
There is an urgent need to develop data-driven strategies that can accelerate and scale up microbial dechlorination for contaminated environments. Researchers report a new machine learning framework that integrates experimental features with microbial biofilm data to optimize bioelectrodechlorination.

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.

NewsMeasles immunity 90% in BC’s Lower Mainland
In British Columbia’s Lower Mainland, 90% of people have detectable antibodies against measles, indicating high vaccine coverage and population protection, according to a new study.

NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.

NewsToxoplasmosis: how the pathogen exploits its own envelope
Researchers have developed a novel imaging technique that allows reliable visualization of the process of endocytosis in Toxoplasma for the first time. The material enters the pathogen through a micropore in its cell membrane.
-
NewsSped-up evolution may help bacteria take hold in gut microbiome
A genetic mechanism inserts mutations into key DNA hotspots that enable bacteria to adapt to new environments, a new study finds.
-
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.
-
NewsExpanding the genetic toolkit: nitrogen-response promoters developed for Bacillus licheniformis
Promoters are crucial expression elements in synthetic biology, and Bacillus licheniformis serves as an excellent chassis cell for industrial production, but is restricted by a lack of nitrogen source-responsive promoters.
-
NewsMolecular bodyguard helps infections persist
Researchers have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective shield for bacterial genes — and points to new strategies for fighting persistent infections.
-
NewsEarth’s oxygen boom: a fresh perspective for a billion-year-old problem
A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life.
