NewsGut bacteria from amphibians and reptiles achieve complete tumor elimination
Researchers have discovered that the bacterium Ewingella americana, isolated from the intestines of Japanese tree frogs (Dryophytes japonicus), possesses remarkably potent anticancer activity.

NewsA fatal mix-up: How certain gut bacteria drive multiple sclerosis
If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis.

NewsOroya fever: Elucidation of disease mechanism opens possibility for novel therapy
An international research team has generated and analyzed more than 1,700 genetic variants of the pathogen that causes Oroya fever, identifying two proteins that Bartonella requires for the destruction of red blood cells.

NewsStreptococcus suis serotype 2 collagenase-like protease promotes meningitis by increasing blood-brain barrier permeability
Streptococcus suis serotype 2 (SS2) is an emerging zoonotic pathogen that causes meningitis in humans and pigs. Researchers have investigated the role and mechanism of the SS2 Clp in promoting the passage of the bacterium across the blood-brain barrier (BBB).

NewsHarmless Klebsiella strain shows powerful protection against gut infections in Inflammatory Bowel Disease (IBD) model
A new study demonstrates that a harmless strain of Klebsiella can eliminate infections and reduce gut inflammation in mouse models of inflammatory bowel disease (IBD).
-
NewsSwedish freshwater bacteria give new insights into bacterial evolution
Researchers analyzing the DNA of all known Caulobacterales species, including newly collected samples from Swedish and Finnish forest lakes, discovered that several freshwater species lacked more than a hundred genes typically linked to the group’s complex lifecycle.

NewsNovel kirkovirus may be associated with colitis in horses
In a pilot study, researchers have found a novel kirkovirus that may be associated with colitis – and potentially small colon impactions – in horses. The study could offer a route to new therapies for horses with colitis symptoms from unknown causes.

NewsFecal tests reveal active termite attacks
Termite pellets can linger long after the insects that dropped them have disappeared. By testing for microbes in the excrement, researchers can distinguish old droppings from fresh, and whether a colony is actively chewing its way through a home.

NewsStudy links gut bacteria to bloodstream infections in newborns within sub-Saharan Africa for the first time
New research has shown gut and bloodstream infections are caused by the same bacteria giving hope of better prevention and diagnosis of deadly neonatal sepsis.
-
NewsCould hidden infections be fueling long COVID?
For millions suffering from long COVID, their persistent breathlessness, brain fog and fatigue remain a maddening mystery, but microbiologists think they may have cracked the case. The review argues that co-infections acquired before or during COVID could cause symptoms to persist indefinitely for many people.
-
NewsEngineering oncolytic bacteria as precision cancer therapeutics
A new review summarizes recent advances in the design and application of synthetic biological strategies that enhance bacterial precision, safety, and efficacy in tumor therapy.
-
NewsBacteria double as Trojan horse for artificial amino acids
Researchers have hijacked a natural transport system of the bacterium E. coli to develop a solution that allows artificial amino acids to be introduced into bacteria efficiently. This means the “amino acid toolbox” can be expanded for widespread use in medicine and the biotech industry.

NewsPersistent antibiotic resistance of cholera-causing bacteria in Africa revealed
In 2024, representatives from 14 African countries came together for a five-day intensive workshop on a whole-genome sequencing method called Oxford Nanopore Technology (ONT) aimed at strengthening cholera surveillance capabilities across the continent.
-
NewsScalable nanoengineered gauze with sustained natural product release
A multi-institutional Chinese research team has developed PPCZ@Gauze – a novel nanoengineered dressing that synergistically combines antibacterial, anti-adhesive, and pro-angiogenic functions.
-
NewsOpioid use linked to higher risk of C. difficile infection
New research from the University of Georgia suggests that opioid use could make patients more vulnerable to infections. The meta-analysis examined four studies of almost 120,000 patients. The researchers found that about 31% of patients who were prescribed and taking opioids caught C. diff, compared to 17% of patients who weren’t using them.

NewsCloves and miswak: Antimicrobial effects of Syzygium aromaticum and Salvadora persica against common pathogens in vitro
Clove essential oil (CEO) derived from Syzygium aromaticum and miswak (Salvadora persica) contains bioactive compounds with antimicrobial properties. This study aimed to evaluate the in vitro antimicrobial efficacy of CEO, miswak, and their combination against key peri-implantitis pathogens.

NewsScientists create microneedle system to deliver living biofertiliser directly into plants, boosting growth with less waste
A dissolving patch delivers beneficial microbes into leaves and stems, speeding growth in vegetables while using over 15 per cent less biofertiliser than soil application.
-
NewsStudy reveals promising gut-targeted therapy for C. difficile infections
Researchers have uncovered how the body’s bile acids bind to block C. diff’s most dangerous toxin. The research has informed the development of a new compound that can protect against C. diff in preclinical models, offering hope for safer, more effective treatments.

NewsIncreased risk of severe bacterial infection after high teenage BMI
High BMI and poor physical fitness during later adolescence increase the risk of both contracting and dying from sepsis and other severe bacterial infections in adulthood, according to a study.

CareersSummer studentship: Lucy creates a synthetic microbiome to study mosquito-borne diseases at different life stages
Lucy Ella Malvern reports back on her AMI-sponsored summer studentship which investigated microbiome assembly in mosquitoes across developmental stages.
