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.

NewsStudy suggests that chlorine treatment may impact the risk of legionnaires’ disease
Preliminary results of a nationwide study suggest that the disinfectant used to treat water before it is distributed through pipes may impact the incidence of Legionnaire’s disease in certain parts of the country.

NewsHow did Bronze Age plague spread? Ancient sheep might solve the mystery
Researchers have found the first evidence of a Bronze Age plague infection in a non-human host. The scientists discovered Y. pestis DNA in a 4,000-year-old domesticated sheep from Arkaim, a fortified settlement located in the Southern Ural Mountains of present-day Russia.

NewsStudy reveals how bacteria resist hostile attacks from rival bacteria
When attacked by bacteria from a different species, Pseudomonas rapidly assembles the type VI secretion system (T6SS) – to inject its aggressor with a toxic cocktail. A new study probes how Pseudomonas can strike back when it has already been hit by a deadly cocktail itself.

NewsTuberculosis: Scientists develop novel drug candidate for combating resistant pathogens
Researchers have developed a promising new substance for targeting bacteria that cause tuberculosis. The team have produced a compound that inhibits the pathogens’ ability to produce energy and causes them to die.

NewsNature’s 10: Ten people who shaped science in 2025
Microbiologists and scientists tackling infectious diseases are among Nature’s annual list of ten people at the heart of some of the biggest science stories of 2025.

NewsMajor breakthrough against diabetes thanks to a microbial molecule that disarms inflammation
Researchers have uncovered a surprising ally in the fight against insulin resistance and type 2 diabetes: a microbial metabolite called trimethylamine. TMA, produced by gut bacteria from dietary choline can block a key immune pathway and improve blood sugar control.

NewsChemical structures of surface polysaccharides from Acinetobacter baumannii for glycoconjugate vaccines
Researchers provided a comprehensive analysis of the molecules that make up the protective layer of complex sugars on the surface of Acinetobacter baumannii - known as capsular polysaccharides (CPS) and lipopolysaccharides (LPS), and essential for the bacterium’s virulence.

NewsPreviously unrecognized pathway in plants and phytoplankton offers mercury-detox powers
Primary producers—including phytoplankton—possess a previously overlooked ability to internally break down and detoxify methylmercury. The demethylation pathway rapidly converts methylmercury into less toxic inorganic mercury, which is subsequently reduced to gaseous Hg⁰.

CareersAMR in aquatic ecosystems: A One Health investigation in an irrigation dam in Thailand
Dr Kwanrawee Joy Sirikanchana outlines how her team has launched a major project to address an overlooked question: How much does aquaculture contribute to AMR in shared water systems, and what does this mean for people, animals, and wildlife living around them?

NewsResearchers identify bacterial enzyme that can cause fatal heart conditions with pneumonia infections
Researchers have identified a bacterial enzyme that may be the reason some people get heart complications with pneumonia, while others do not. Since enzymes create chemical reactions to help bacteria survive, grow, and sometimes attack tissues, zmpB could become a target for future therapies.

NewsVolcanic eruptions set off a chain of events that brought the Black Death to Europe
Researchers have used a combination of climate data and documentary evidence to paint the most complete picture to date of the ‘perfect storm’ that led to the deaths of tens of millions of people, as well as profound demographic, economic, political, cultural and religious change.

NewsDo oral bacteria from tooth infections worsen diabetes risk?
A new study demonstrates that Porphyromonas gingivalis and its lipopolysaccharide are potent drivers of both periapical bone destruction and systemic metabolic dysfunction, acting through an IL-17–dependent inflammatory pathway.
-
NewsComplex life developed earlier than previously thought, study reveals
New research indicates that complex organisms evolved long before there were substantial levels of oxygen in the atmosphere, something which had previously been considered a prerequisite to the evolution of complex life.

NewsThe power of gut enzymes: why healthy eating affects everyone differently
Researchers have uncovered a mechanism that determines how our gut microbiome processes healthful plant compounds. The chemical cookbook of gut bacteria varies from person to person—and is often disrupted in chronic diseases.

NewsResearchers confirm new rickettsia species found in dogs
Researchers have confirmed that a species of Rickettsia first seen in dogs in 2018 is a new species of bacteria. The new species is associated with symptoms similar to those of Rocky Mountain spotted fever (RMSF) in dogs, but has not yet been found in humans.

NewsPlant ‘first responder’ cells warn neighbors about bacterial pathogens
Researchers have found that a subset of epidermal cells in plant leaves serves as early responders to chemical cues from bacterial pathogens and communicate this information to neighbors through a local traveling wave of calcium ions.
-
NewsAntibiotics could trigger immune response through gut microbiome metabolites
Researchers report how one of the most abundant gut bacteria responds to tetracyclines, a class of commonly prescribed antibiotics. Newly characterized signals released by the bacterium could aid the host’s immune response, inhibit pathogens and restructure the gut microbiome.

NewsStudy links childhood vaccination to lower risk of drug-resistant bacteria
Children in Guatemala who received a common vaccine that helps prevent pneumonia were less likely to carry antibiotic-resistant bacteria, according to a new study examining whether rotavirus (RV) and pneumococcal (PCV13) vaccines reduce gut colonization by a group of bacteria.
