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.

NewsPresurgical vaccine may prevent orthopedic device infections
Researchers have developed a novel presurgical vaccine strategy that may prevent dangerous infections in patients receiving hip, knee, and other joint replacements, creating an injectable scaffold designed to stimulate the immune system.
-
NewsStudy unravels the fungi-cancer connection
A growing body of evidence indicates that the microbiome within the gut and tumors significantly influences cancer initiation, progression, and treatment response. Current research primarily focuses on bacteria, whilst the role of fungi is only now gaining attention.

NewsPositive signs in the fight against superbugs: CHINET 2024 surveillance report
The 2024 CHINET antimicrobial resistance surveillance report uncovers a hopeful trend in China’s battle against bacterial resistance, with a significant reduction in resistance among several key pathogens.
-
NewsGroundbreaking technique unlocks secrets of bacterial shape-shifting
Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the lab. A groundbreaking method could change how researchers study bacterial diversity.

NewsLargest study of nose microbiome helps highlight those at risk of staph aureus infection
People who persistently carry Staphylococcus aureus (S. aureus) in their nose have fewer species of other bacteria, while certain bacteria may help to prevent S. aureus colonisation, according to the findings of the largest-ever study of the nasal microbiome.

NewsResearchers rescue antibiotics from resistance using phototherapy
Researchers have used phototherapy to inhibit a protein in E. coli bacteria that makes them resistant to antibiotics. This new method, if proven safe and effective in living organisms, holds promise for rescuing the effectiveness of antibiotics that bacteria have become resistant to.
-
NewsPoint-of-care rapid tests can improve screening for latent tuberculosis
A new test shows promising results for detecting latent tuberculosis infection in resource-limited settings. Latent tuberculosis is often diagnosed using a laboratory test called QuantiFERON-TB Gold Plus - this was compared with another test, TB-Feron.

NewsPlant extracts show promise in reducing human pathogen risks in agricultural soils
A new study has revealed that natural plant extracts can significantly lower the risks posed by human bacterial pathogens in manure amended agricultural soils. The eco friendly strategy disrupts the communication systems that bacteria use to coordinate harmful activities.
