Reshaping the gut microbiome to boost chemotherapy

A new study has identified a way to reshape the gut microbiome that can enhance the delivery of certain chemotherapies to tumors, making these nanoparticle-based cancer drugs more effective.

News • Information processing in biological systems

'Computing' disease course with bacteria

Bacterial growth could be used for information processing – for example, to predict the severity of an infection. New research results could pave the way for simple and low-cost diagnostic methods.

News • Early detection biomarker

Using gut bacteria to predict diabetes risk

The presence of certain bacteria in the gut microbiota, and fluctuations in a person’s metabolism, have been identified as potential biomarkers for type 2 diabetes years before its onset.

News • Bacterial alterations in MCI

Study links gut microbiome to Alzheimer’s biomarkers

The microbes living in the human gut influence metabolism, immunity, and cardiovascular health. A new study now suggests they may also be closely connected to Alzheimer's disease.

News • Impact on type 2 diabetes

Gut microbiota shape metabolic health after bariatric surgery

Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes, according to a new study.

News • Quicker diagnosis approach

New biosensor for detecting active tuberculosis

A research team is leading the development of a sensor that paves the way for the rapid, selective and cost-effective detection of active tuberculosis infection.

News • Sexually transmitted infections

“Cervix-on-a-chip” to help discover new STI treatments

Scientists from the University of Maryland School of Medicine and colleagues create the first-ever immune-capable “Cervix-on-a-chip” to study sexually transmitted infections (STIs).

News • Accelerated cognitive decline

Study: severe infections may raise dementia risk

Severe infections could increase the risk of developing dementia years later, independently of other coexisting illnesses, a new study from Finland suggests.

News • Affordable diagnostics

Detecting bacterial infection with simple breath test

Bacterial infections can be difficult to distinguish from viral infections and inflammation, but a simple breath test may change that. This could reduce unnecessary antibiotic prescriptions.

News • Dolosigranulum pigrum

“Lazy” bacteria may protect against long Covid

Scientists have discovered the protective role of a bacterium that could prevent long Covid. Their discovery could lead to the development of new therapy approaches.

News • Study on bacteria composition

Antibiotics leave a lasting mark on the gut microbiome

Antibiotics can affect the composition of the community of bacteria living in the gut, known as the gut microbiome, for as long as four to eight years after treatment, a new study shows.

News • Biofilm-based resistance mechanism

Bacteria build “bunkers” to withstand antibiotic treatment

“The bacteria effectively hide in a bunker”: New research reveals a surprising mechanism used by Acinetobacter baumannii and Pseudomonas aeruginosa to protect themselves from antibiotics.

News • Microbial interactions

Gut bacteria interactions show promise as health and disease marker

To better distinguish between healthy and diseased gut microbiomes, scientists have created an index that tracks microbial behavior and signals conditions such as colorectal cancer.

News • (B)eating cancer

Bacteria to consume tumours from the inside out

A research team led by the University of Waterloo is developing a novel tool to treat cancer by engineering hungry bacteria to literally eat tumours from the inside out.

News • Plasmid-specific ecological adaptation

How antimicrobial resistance spreads from gut bacteria to hospital superbugs

Researchers have uncovered how a high-risk class of genetic vectors can efficiently spread antibiotic resistance within the gut, enabling even highly virulent bacteria to acquire drug resistance.

News • Systemic mechanism discovered

Chemotherapy rewires gut bacteria to curb metastasis

Chemotherapy does more than kill cancer cells: It reshapes the gut microbiome, making the body less permissive to metastasis. This finding opens new avenues for adjuvant strategies.

News • Rapid diagnostics

New system simultaneously detects antibiotic resistence and virulence of K. pneumoniae

Now, a research team has developed a novel diagnostic approach that enables the rapid and simultaneous detection of both antibiotic resistance and high virulence in Klebsiella pneumoniae.

News • When good bacteria fight back

Klebsiella strain to protect against IBD gut infections

New research shows that a harmless strain of Klebsiella – discovered by chance in laboratory experiments – can eliminate infections and reduce gut inflammation in inflammatory bowel disease (IBD).

News • Historia pestilentiae

How volcanic eruptions brought the Black Death to Europe

From volcanic activity to the deaths of millions: Using climate data and documentary evidence, researchers have painted a detailed picture of how the Black Death pandemic reached Europe.

News • Dissemination of antimicrobial resistance

Microplastics serve as hideout for AMR bacteria, study finds

Microplastics pose a human health risk in more ways than one, a new study reveals: not only do the particles harbor pathogenic bacteria, they may also help the spread of antimicrobial resistance.

News • New insights on nosocomial pathogen

Research reveals ‘hidden movement’ of Pseudomonas aeruginosa

Pseudomonas aeruginosa, a hospital-acquired bacterium that causes serious infections, can move from the lungs to the gut inside the same patient, raising the risk of sepsis, new research reveals.

News • Bacteria-eating viruses

New phages spark hope against hospital superbug

A team of researchers comprehensively catalogued a new collection of bacteria-eating viruses called phages. These phages could be used to combat Klebsiella pneumoniae - a serious threat in hospitals.
