NewsNew insights into how bacteria control DNA synthesis open the door to next generation antimicrobials
A new study combines structural biology, biophysical characterisation and functional assays to delineate how the bacterial transcriptional regulator NrdR’s quaternary structure responds to different nucleotide states and how these changes affect its regulatory activity.

NewsNewly discovered virus linked to colorectal cancer
Researchers have discovered a previously undescribed virus in a common gut bacterium, Bacteroides fragilis. The virus appears more frequently in patients with colorectal cancer.

NewsResearchers discover how tuberculosis bacteria use a “stealth” mechanism to evade the immune system
New research reveals that mycobacteria release tiny packages called extracellular vesicles that fuse with the membranes of immune cells. These vesicles contain specialized lipids—fatty molecules—that make the cell membrane more rigid.

NewsResearchers discover novel bacteria in Florida’s stranded pygmy sperm whales
Researchers have identified three previously unknown genotypes of Helicobacter bacteria living inside stranded pygmy sperm whales. The study represents the first documented occurrence of these unique Helicobacter genotypes – now designated Kogia Helicobacter 1, 2 and 3 – in pygmy sperm whales.

NewsScientists discover ‘bacterial constipation’, a new disease caused by gut-drying bacteria
Scientists have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus coating essential for keeping the colon lubricated and feces hydrated.

NewsMissing microbes in UK infant gut and probiotics highlighted by global microbiome atlas
A global atlas mapping two key gut bacteria in infants around the world has uncovered a treasure trove of bacterial strains adapted to the infant gut and not found in commercial probiotic products. It lays the foundation for more effective, tailored infant probiotics.

NewsAncestral motif enables broad DNA binding by NIN, a master regulator of rhizobial symbiosis
Researchers investigated the molecular mechanisms whereby the transcription factor NODULE INCEPTION (NIN) - crucial for rhizobial symbiosis - can bind a broader spectrum of DNA sequences than its close homologs, using the legume Lotus japonicus (Miyakogusa) as a model system.

NewsNovel vaccine protects against C. diff disease and recurrence
A novel vaccination approach cleared the harmful gut bacterium Clostridioides difficile in an animal model of infection. An experimental vaccine administered to the mucosal lining of the colon protected against illness, death, tissue damage and infection recurrence.

NewsAntimicrobial resistance in foodborne bacteria remains a public health concern in Europe
Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from EFSA and ECDC.

NewsComplexity key to preventing infection after heart surgery
Research indicates that uniform materials could be the culprit behind deadly infections that can occur when using synthetic materials for cardiovascular grafts.
-
NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.
-
NewsMicrobes harvest metals from meteorites aboard space station
Microorganisms can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth. Researchers have studied how those microorganisms extract platinum group elements from a meteorite in microgravity, with an experiment conducted aboard the International Space Station.

NewsHow bacteria may promote breast cancer
Researchers have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known as spermine oxidase (SMOX).
-
NewsStrategic changes in water treatment could prevent disease outbreaks
A breakthrough new study shows how strategic changes in water treatment effectively treated a deadly outbreak of Legionnaires’ Disease. For the first time, the study provides evidence of an outbreak being stopped by introducing disinfection to previously untreated groundwater.
-
NewsBacteria frozen in ancient underground ice cave found to be resistant against 10 modern antibiotics
Researchers tested antibiotic resistance profiles of a bacterial strain that until recently was hidden in a 5,000-year-old layer of ice of an underground ice cave – and found it could be an opportunity for developing new strategies to prevent the rise of antibiotic resistance.
-
NewsRhododendron-derived drugs now made by bacteria
Bioengineered E. coli bacteria can now produce a group of compounds with anticancer, anti-HIV, antidiabetic and anti-inflammatory activities. The compounds, orsellinic acid-derived meroterpenoids, are produced by Rhododendron species.
-
NewsGut microbiome may be the link to gluten sensitivity without celiac disease
Researchers found that after antibiotic treatment, mice exposed to gluten had changes in the bacteria living in the gut. These shifts in bacteria types altered how they processed carbohydrates, fats and sugars which may influence how these nutrients are recognized by the immune system.

NewsLactobacillus rhamnosus L34: Native probiotic that reduces inflammation in patients with chronic kidney disease
Researchers in Thailand have discovered a native probiotic strain, Lactobacillus rhamnosus L34, that helps reduce uremic toxins and inflammation-related cytokines in patients with chronic kidney disease (CKD) before dialysis.

NewsNewly discovered bacterium converts carbon dioxide into chemicals using electricity
A newly identified soil bacterium may help unlock cleaner ways to recycle carbon dioxide and produce valuable chemicals using electricity. The sulfate reducing bacterium Fundidesulfovibrio terrae possesses an unusual ability to both export and absorb electrical energy while converting carbon dioxide into acetate.

NewsBeneficial bacterium deployed to protect turfgrass from fungal foes
A novel strain of Bacillus subtilis helps a variety of plants resist soil‑borne diseases, retain moisture and develop stronger root‑to‑shoot growth. New findings on the effect of UD1022 on dollar spot disease suggests intriguing implications for manufacturing of biological treatments for the fungal disease.
