One health
Communicable diseases remain one of the major causes of mortality worldwide. There are disparities in the numbers of individuals affected by disease between low-and-middle-income countries and those in developed nations. Microbes will play in important role in drug discovery: producing anticancer drugs and antimicrobials. Applying One Health principles, to understand the interaction of pathogens and the human host, development of diagnostics, treatments, and disease prevention, applied microbiologists can shape global health and wellbeing outcomes.

New research confirms HPV vaccination prevents cervical cancer
Two new Cochrane reviews show strong and consistent evidence that HPV vaccines are effective in preventing cervical cancer and pre-cancerous changes, especially when given to young people before they are exposed to the virus.

NewsResearchers subvert plasmids to combat antibiotic resistance
Scientists have devised a way to track the evolution and spread of antibiotic resistance in individual bacteria by measuring competition among plasmids. Plasmids evolve independently but also help drive bacterial evolution, including the development of resistance to antimicrobial compounds. They are the primary way that resistance can jump from one type of bacteria to another.
NewsToxic gut bacteria may drive ulcerative colitis by killing protective immune cells
A toxin-secreting gut bacterium may fuel ulcerative colitis by killing protective immune cells that maintain intestinal homeostasis, according to a new study. The findings suggest potential for new treatment strategies.
NewsRebalancing lung repair with immune damage is key to surviving severe influenza
Recovery from deadly influenza infection may hinge on helping the lungs heal in addition to stopping the virus, according to a new study in mice, which shows that pairing modest antiviral therapies with immune modulation can restore damaged tissues and lung function, even after severe infection has taken hold.

Hear us out: scientists say garlic shows promise as a mouthwash alternative
Garlic extract demonstrates antimicrobial efficacy comparable to other widely used antiseptics and disinfectants, such as chlorhexidine, according to scientists. While garlic-based mouthwash may cause more discomfort than chlorhexidine, it offers longer-lasting residual effects.
NewsNew study finds higher levels of antimicrobial resistance (AMR) in surface water during winter
A new study has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter. Flooding, sewer overflows and agricultural run-off all contribute to a cocktail of pollutants that can increase AMR genes in surface water, potentially turning regular bugs into ‘superbugs’.
NewsThe road ahead: why conserving the invisible 99% of life is fundamental to planetary health
A new paper outlines how scientists came together to put together the first microbial conservation roadmap under the leadership of Applied Microbiology International President, Professor Jack Gilbert.
NewsDiphtheria toxin fragment harnessed to fuse lipid vesicles at neutral pH
Researchers have discovered a novel way to fuse lipid vesicles at neutral pH. By harnessing a fragment of the diphtheria toxin, the team achieved vesicle membrane fusion without the need for pre-treatment or harsh conditions, opening the door to new applications.
NewsLivestock manure linked to the rapid spread of hidden antibiotic resistance threats in farmland soils
Scientists have uncovered how even “low-risk” organic fertilizers like dried poultry manure can inadvertently drive a dramatic surge in dangerous antibiotic resistance genes, once released into vegetable plots used for food crops.
NewsMaternal health programme cuts infection deaths by 32%
A landmark multi-country clinical trial has shown that a structured, sustainable approach to infection prevention and treatment can save women’s lives, cutting severe maternal infections and deaths by about one-third (32%) compared to usual care.
NewsResearchers diagnose disease with a drop of blood, a microscope and AI
Scientists have developed an automated, high-throughput system that relies on imaging droplets of biofluids for disease diagnosis in an attempt to reduce the number of consumables and equipment needed for biomedical testing.
NewsScientists use computer model to improve hospitals’ ability to limit spread of drug-resistant infections
The computer model improves on traditional methods like contact tracing by inferring asymptomatic carriers in the spread of antibiotic-resistant infections.
NewsDrinking water people believe to be safe and clean often contain potentially dangerous bacteria
A study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria. Bottled water sold in large refillable jugs was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination.
NewsWorld’s largest metabolomic study completed, paving way for predictive medicine
UK Biobank has today released the final set of data on nearly 250 metabolites in half a million volunteers. This completes the world’s largest ever metabolomic study, which will help drive treatment strategies for neurological conditions, heart disease and cancer.
NewsSmart toilet designs in Cambodia held promise, but a key piece was missing
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was missing: using it correctly.
NewsStudy unveils structure, identification and characterization of the RibD-enolase complex in Francisella
A study aiming to identify anti-tularemia drug targets determined the atomic structure and identified its components of the native RibD-enolase protein complex in Francisella novicida.
NewsNew nanogel technology destroys drug-resistant bacteria in hours
A novel technology shows over 99.9% effectiveness against Pseudomonas aeruginosa (P. aeruginosa). It centres on a heteromultivalent nanogel: a flexible particle made by crosslinking polymers and adding sugar residues (galactose and fucose) alongside antimicrobial peptides.
NewsBacteria ‘pills’ could detect gut diseases — without the endoscope
Researchers report that they’ve developed a sensor made of tiny microspheres packed with blood-sensing bacteria that detect markers of gastrointestinal disease. Taken orally, the miniature “pills” also contain magnetic particles that make them easy to collect from stool. Excreted from mouse models with colitis, the bacterial sensor detected gastrointestinal bleeding within minutes.
NewsGSK and Fleming Initiative scientists unite to target AMR with advanced AI
GSK and the Fleming Initiative have announced six major new research programmes, called ‘Grand Challenges’ which harness some of the best scientific expertise and the latest technologies, including advanced AI, to find new ways to slow the progress of antimicrobial resistance (AMR).
NewsProbiotic bifidobacterium may boost cancer treatment and suppress tumors
A new review explores how bifidobacterium, a common probiotic found in the gut, may contribute to cancer prevention and therapy. The authors highlight the growing importance of gut health in cancer treatment and shed light on how bifidobacterium could complement standard cancer therapies.
NewsGut bacterium impairs liver cancer treatment, inducing immunotherapy resistance
Researchers discovered that transplanting the gut bacterium Phocaeicola vulgatus into mouse models of liver cancer induced immunotherapy resistance. The finding is consistent with clinical observations in patients, showing that patients with low levels of P. vulgatus responded better to treatment.
