NewsPertussis resurgence in Tuscany outlines importance of timely vaccination in Italy
Research analysing 2016-2024 data from all pertussis-related hospitalisations in Tuscany, Italy, finds a ninefold increase in pertussis cases in 2024 among children and adolescents.

NewsGI tumor microbes may predict prognosis and inform treatment
Intratumor microbes can play a role in disease progression and response to treatment. Researchers have identified core tumor microbiota associated with disease progression and risk, developing a microbiota-based risk score that can predict response to therapy.

NewsWelsh mine microbes mapped to help heat homes
Welsh scientists have mapped the hidden microbes thriving in south Wales’s abandoned coal mines, helping to overcome obstacles to using mine water to heat Britain’s homes.

NewsNew bacterium discovered in the Amazon is closely related to Andean species that causes human bartonellosis
A new species of bacteria of the genus Bartonella has been found in the Amazon National Park in the state of Pará, Brazil, in phlebotomine insects, also known as sand flies. Its DNA is similar to that of two other Andean species of bacteria.

NewsNew research rewrites origins of world’s first recorded pandemic - the Plague of Justinian
For the first time, researchers have uncovered direct genomic evidence of the bacterium behind the Plague of Justinian — the world’s first recorded pandemic — in the Eastern Mediterranean, where the outbreak was first described nearly 1,500 years ago.

NewsMyocardial infarction may be an infectious disease
A pioneering study has demonstrated for the first time that myocardial infarction may be an infectious disease. This discovery challenges the conventional understanding of the pathogenesis of myocardial infarction and opens new avenues for treatment.

NewsResearchers uncover sensory abilities of bacteria in the gut
An international team has shown that commensal bacteria can perceive and respond to diverse chemical stimuli in their environment. They focused on Clostridia, motile bacteria that play an important role in gut health.

NewsScientists reveal the first structure of the complete botulinum neurotoxin complex
Researchers have succeeded in creating a molecular blueprint of how one of the world’s most dangerous toxins, botulinum toxin, is structured, stabilised, delivered and released. The research paves the way for more effective drugs.

NewsAlcohol opens the floodgates for bad bacteria
Scientists have found that chronic alcohol use impairs the production of a key cellular signaling protein that helps keep gut bacteria within the gut. Without this guardrail in place, bacteria from the gut can more easily migrate to the liver, exacerbating liver damage caused by alcohol.

NewsStudy exposes sewage contamination locations threatening West Hawai’i coral reefs
New research reveals the extent to which sewage pollution threatens the fragile coral reef ecosystems of West Hawaiʻi Island. Researchers pinpointed locations where high levels of fecal bacteria associated with populated coastal areas are driving worsening contamination.

OpinionSafety and nutritional claims for raw milk
Robert F Kennedy Jr. famously advocates drinking raw milk and promotes its benefits. But how safe is unpasteurised milk? Nicola Holden and Gil Domingue, who sit on Applied Microbiology International’s Food Security Scientific Advisory Group, take a deep dive into the science.

NewsMouth to gut bacteria migration explains why smoking is good for inflamed bowels
Researchers have discovered why smoking tobacco helps people suffering from ulcerative colitis. The study shows that smoking produces metabolites that encourage bacteria from the mouth to grow in the large intestines where they trigger an immune response.

NewsBacteria strains infecting cattle and humans in US are highly similar
Salmonella Dublin, a type of bacteria that primarily infects cattle but some strains also can adapt to infect humans, is increasingly becoming resistant to antibiotics, making it a growing public health threat.

NewsGut bacteria can reveal colorectal cancer
Researchers identified all human gut bacteria to a level of detail that uncovers the physiological importance of the different microbial subgroups. This inventory was then used to detect the presence of colorectal cancer according to the bacteria present in simple stool samples.

NewsColibactin-producing E. coli linked to higher colorectal cancer risk in FAP patients
Researchers have found that patients carrying colibactin-producing Escherichia coli in their colon polyps were more than three times as likely to have a history of colorectal cancer compared to those without the bacterium.

NewsKidney fibrosis linked to molecule made by gut bacteria
A molecule made by bacteria in the gut can hitch a ride to the kidneys, where it sets off a chain reaction of inflammation, scarring and fibrosis — a serious complication of diabetes and a leading cause of kidney failure.

NewsNew AI tool reveals how drugs kill tuberculosis
A new study offers a powerful AI-assisted method for uncovering exactly how TB drugs kill the bacteria, opening the door to smarter treatment combinations that could work faster.

NewsMaternal antibodies in breast milk regulate early immune responses in mouse gut
In mice, maternal antibodies ingested in breast milk in the first week after birth help to regulate immune responses in the newborn gut, according to a new study.

NewsArchaea can kill bacteria with new antibacterials
A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials.

NewsResearchers use generative AI to design compounds that can kill drug-resistant bacteria
With help from artificial intelligence, researchers have designed novel antibiotics that can combat two hard-to-treat infections: drug-resistant Neisseria gonorrhoeae and multi-drug-resistant Staphylococcus aureus (MRSA).
