NewsThe usefulness of labelled white blood cells in diagnosing necrotizing external otitis
Using radiopharmaceutical technology, researchers can reliably and conveniently diagnose and monitor necrotizing external otitis, a rare disease of the skull base.

NewsDangerous strings of bacteria use flow to spread colonies
Researchers have identified how certain dangerous bacteria are spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single bacteria attach to a surface and elongate before dividing, producing chains without ever separating.

NewsResearchers discover first PLP-dependent enzyme that influences bacterial protein production
Researchers discovered aminovaleramididine synthetase (AvaS), the first pyridoxal phosphate (PLP)-dependent enzyme involved in tRNA modification, expanding scientific understanding of how RNA shapes the reading of genetic information. The discovery reveals a previously unknown mechanism that bacteria use to regulate protein production.

NewsThese bacteria can change their diet to survive inside the body
The team have found that Staphylococcus aureus can adjust its diet depending on what sources remain available. The bacterium can adjust its inner workings in response to any one of a number of different sulfur-containing compounds — like cysteine, glutathione or thiosulfate.

NewsAMI welcomes new member to its Board of Trustees
Applied Microbiology International has welcomed Professor Les Baillie as the latest member of its Board of Trustees. We also bid a fond farewell and thank you to Professor Diane Purchase who is leaving the Board.

NewsC. diff coordinates threat response to survive in gut
Researchers have discovered a unique system C. diff uses to simultaneously sense and respond to two different threats: host-mediated nutrient deprivation and a microbiota-produced antibiotic compound, suggesting new therapeutic options for preventing and treating C. diff infections.

NewsEngineering bacterial surfaces with glucan nanofilms creates a potent vaccine platform against invasive fungal infections
A research team has developed a synthetic bacterium-based vaccine platform that uses engineered bacterial surfaces to assemble glucan nanofilms for enhanced antifungal immunity against pathogens such as Candida albicans.

NewsFusobacterium nucleatum drives immunosuppression and metastasis in TNBC
A new study identifies Fusobacterium nucleatum, a Gram-negative anaerobic bacterium associated with several cancers, as a key driver of tryptophan metabolic reprogramming, immunosuppression and lung metastasis in triple-negative breast cancer.

NewsA pan-sRNome analysis identifies novel regulatory small RNAs involved in Pseudomonas aeruginosa virulence
A characterization of nine newly discovered sRNAs reveals their regulatory networks in quorum sensing, biofilm formation, and interbacterial competition in Pseudomonas aeruginosa.

NewsHeatwaves inhibit antibiotic resistance in soils - but at a price
Heatwaves temporarily reduce the amount of resistance genes in the soil, but heat and droughts are also causing significant damage to soils and ecosystems. The temporary dip in resistance therefore does not mean that the health risks from antibiotic resistance disappear.

NewsProbiotic use surges - but microbiome-supportive food consumption stagnates
New research finds that probiotic supplement use has surged in the United States, while the consumption of microbiome-supportive foods has remained virtually unchanged. According to a study published in Clinical Gastroenterology and Hepatology, the consumption of probiotic supplements increased 287% among adults from 2009-2023 and 786% among ...

NewsToxic tail: Biologists find a hidden weak spot in how bacteria build the tails they use to move
New research has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. Building these tails can put stress on the protective wall surrounding a bacterial cell, and uncovered systems bacteria use to keep that stress from becoming destructive.

NewsHelicobacter pylori exposure may be linked to more than 1 in 5 bowel cancer cases worldwide
Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study - and those born in more recent decades may be more at risk of the disease after exposure.

NewsBacterial trial fails to demonstrate early asthma prevention - prompting rethink of 'hygiene hypothesis'
A national clinical trial has found that treating young children with an oral bacterial extract did not reduce the risk of severe wheezing and respiratory illnesses that can precede asthma, potentially prompting researchers to rethink aspects of the hygiene hypothesis.

NewsCommonly used cancer drugs boost MRSA antibiotics – new research
Scientists tested five anti-cancer drugs and revealed that four of them helped penicillin-type antibiotics to kill MRSA. These drugs interfere with the bacteria’s ability to make DNA, making the bacteria more vulnerable to the antibiotics.

NewsResearch explores why strep throat can linger, even after treatment with antibiotics
Streptococcal sore throat can linger even after treatment, turning otherwise healthy children into carriers. Using whole genome sequencing, researchers hope to discover why.

NewsRiver drinking water sources may face greater antibiotic resistance risks than reservoirs, study finds
A basin-wide study of 13 drinking water sources in China’s Poyang Lake region shows that water source type can strongly shape the occurrence and spread of antibiotics, antibiotic resistance genes, and resistant bacteria.

NewsMember Q&A: Harta Wedari on how AMI has opened up new opportunities and communities
Dr Ni Luh Putu Harta Wedari, a medical doctor and Clinical Microbiology Specialist from Bali, Indonesia reveals how engaging with AMI has expanded her international network and unveiled new opportunities.

NewsSmall bowel microbiome offers clues to women’s health
A new study has identified differences in the makeup and organization of the small bowel microbiome between women and men. One intriguing finding was a bacterial community containing Granulicatella, found only in women.

NewsA fourth T6SS in clinical Pseudomonas aeruginosa deploys the pore-forming effector TseMt
The hospital-associated pathogen Pseudomonas aeruginosa has type VI secretion systems (T6SSs). Most reference strains encode three T6SSs, but comparative genomics has identified an additional H4-T6SS in a subset of clinical isolates.
