“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 • Assessing infection risk

Predicting neonatal sepsis with vaginal microbial swabs

A new study shows that analyzing bacteria from vaginal swab samples taken at delivery could help predict the risk of neonatal sepsis.

News • Fungal effect on skin cancer

Candida albicans increases melanoma aggressiveness, study shows

Reseachers show how Candida albicans – a fungus living in our body – can make melanoma more aggressive. The results pave the way for antifungal therapies to complement skin cancer treatments.

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.

Article • Hospital hygiene

Breaking chains of infection to combat antimicrobial resistance

With antimicrobial resistance causing over 5 million deaths annually, rapid outbreak detection is critical. A German lab demonstrates how FTIR spectroscopy can transform hospital infection control.

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 • 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.

News • Research reveals infiltrating microbes

How bacteria in tumors drive treatment resistance in cancer

Researchers have discovered a previously unknown mechanism that explains how bacteria within a tumor can drive treatment resistance in patients with oral and colorectal cancer.

News • Implicit information

In-depth AI microbiome analysis reveals colorectal cancer

Scientists developed an AI-based approach to diagnose colorectal cancer from different microbial subgroups in the gut microbiota – a non-invasive and low-cost alternative to colonoscopy screening.

News • Review explores bacterial impact

Vaginal microbiome holds untapped potential for women's health

The vaginal microbiome is a largely overlooked area of medicine that could dramatically improve outcomes for common infections, infertility and even cancer for millions of women, a new review finds.

News • Weakened defenses

Antibiotics are not the only meds disrupting the gut microbiome

Antibiotics are known for disrupting the microbiome in the gut and thus paving the way for diseases. However, many common non-antibiotics also have this effect, a new study shows.

News • Barrier effect research

Using bacteria to improve microbiota resistance to pathogens

Microbiota composition can help prevent pathogenic bacteria from proliferating, known as the barrier effect. Now, scientists have identified seven bacteria involved, paving the way for new therapies.

News • Intestinal disease diagnosis

Next-generation tools find infections missed by standard tests

A University of Liverpool study has used advanced genetic and genomic techniques to offer a major step forward in understanding and diagnosing infectious intestinal diseases.

News • Focus on mutation frequency decline

A new strategy to combat antibiotic resistance

Finding ways to target antibiotic-resistant bacteria is a scientific and medical priority. A consortium of researchers identified a compound capable of blocking a key protein for virulence, thus “disarming” the pathogenic bacteria.

News • Study on Staphylococcus aureus

Understanding bacterial antiviral defenses to tackle antibiotic resistance

In a new study, researchers show that the emergence of antibiotic resistance can be understood in the mechanism of how bacteria build up defences against being infected by viruses.

News • A closer look at the GI microbiome

“Gut-on-a-chip” predicts immunotherapy efficacy against melanoma

The gastrointestinal microbiome holds valuable information that can help predict whether immunotherapy will be successful against melanoma. A new “gut-on-a-chip” is designed to do exactly that.
