NewsDrug helps bladder cells to clear urinary infections
Researchers have identified a way to strengthen the bladder cells’ ability to eliminate urinary tract infection bacteria sheltered in the cells of the epiithelium. The drug OM-89, marketed as Uro-Vaxom®, activates cellular degradation pathways in bladder epithelial cells while also increasing the amount of antibiotic that enters them.

NewsBlood test shows whether newborns with fever have bacterial or viral infection
A new study suggests a test that compares the levels of two molecules in the blood is able to accurately distinguish between bacterial and viral infections in newborn babies with fever.

NewsHow straw is returned to soil can make a major difference in nitrous oxide emissions
Returning crop straw to farmland is widely used to recycle nutrients and improve soil quality. But new research shows that the way straw is returned to soil can strongly influence how effectively it limits emissions of nitrous oxide, a potent greenhouse gas.

NewsGut microbiome can reveal risk of type 2 diabetes
Changes in the composition of bacteria in the gut could provide early warning of type 2 diabetes (T2D), new research has found. The analysis of data from hundreds of thousands of individuals identified hundreds of changes in the composition of the gut microbiome that can be detected before the onset of any changes in blood glucose measures.

NewsFrog’s coat of bacterial armor helps protect it from fungal disease
The bacteria living on frogs’ skin could serve a vital role in protecting the animal from a deadly fungal disease. A team of researchers found that frogs’ natural skin bacteria can help them fight disease and improve their chances of survival.

NewsGut bacteria-derived metabolite contributes to host lifespan extension
Researchers use genetically engineered Escherichia coli to reveal how gut bacteria-derived polyamines extend the lifespan of fruit flies.

NewsA new mechanism of action against an old enemy
Researchers identified corramycin as a promising candidate against Mycobacterium tuberculosis. In the laboratory, the natural compound is effective against various forms of the tuberculosis pathogen, including strains from clinical samples that are already resistant to common antibiotics.

NewsResearchers uncover what could make some bacteria-killing viruses more effective than others
Bacteriophages — or phages, for short — are viruses that kill bacteria, and scientists have been studying them for decades as a possible solution to antibiotic-resistant infections. But phages are notoriously picky eaters — a phage that can eradicate one bacterial strain is often powerless against others, even if the ...

NewsCorals show ‘vaccine-like’ responses after pathogen exposure
To boost the resilience of corals in the face of increasing sea temperatures and the spread of disease, researchers have found that controlled, low-level exposure to dead pathogenic cells can help corals resist future infection.

NewsSimple cleaning reduced bacteria on single-use medical devices
Three simple cleaning methods reduced bacterial levels on used single-use medical devices, according to a study. The findings could prove useful as a last-resort measure during severe shortages of medical supplies in a crisis or war.

NewsScientists reveal tissue culture-free (“ex vitro”) transformation method for trees
This technology introduces a novel “ex vitro” transformation method that utilizes Agrobacterium rhizogenes to genetically modify the roots of woody plants without the necessity for tissue culture.

NewsRainwater tanks may be harbouring hidden health risks
Rainwater tanks are a popular way for Australians to save water, but new research has found they can also harbour potentially harmful bacteria and metals that could pose health concerns.

NewsCyanobacterium found in clean lakes shows little toxic potential
Scientists have assembled the first complete genomes of Gloeotrichia echinulata, comparing DNA of samples from both West Coast and Northeast lakes. They found no evidence of the machinery required to produce the toxins commonly associated with cyanobacteria.

NewsResearch could lead to better prevention for a common cause of newborn meningitis
A new research project will investigate how Strep B bacteria attach to the vaginal tract and the mechanisms they use to stay there. In newborns, Strep B infections can kill and the study will look at how Streptococcus agalactiae comes to colonize the birth canal in the first place, which may lead to improved preventative measures.

NewsScientists uncover genetic changes in the bacteria causing severe Kent meningococcal disease outbreak
Scientists have used bacterial genome sequencing to understand why the meningococcal disease outbreak in Kent earlier this year was so severe. The outbreak bacteria had picked up genetic material from other, less harmful bacteria found naturally in the throats of many healthy people.

NewsNew standardised, contemporary strain panels address a long-standing barrier in AMR research
PACE and the UK Health Security Agency have released five new contemporary antimicrobial resistance (AMR) strain panels, giving innovators worldwide a resource to test novel therapeutics and diagnostics against today’s resistance patterns.

NewsGut microbiome development may help predict type 1 diabetes in children at high risk
A new prospective study found that children at high genetic risk of type 1 diabetes whose gut microbiome development plateaued early had about three times the risk of developing the disease compared with children whose microbiomes continued to mature.

NewsBacteria pulled from local pond water show early promise for cleaning up sewage
A new study identifies green sulphur bacteria from Peshawar pond samples that reduced pollution markers in wastewater after a week of treatment.

NewsA tiny bacterium with a huge impact
Researchers have discovered that gut bacteria and the compounds they produce trigger biological processes that the human body on its own can only activate with difficulty. They help suppress inflammation and may also have beneficial effects on fatty liver disease.

NewsNew study uncovers the complex history of the plague after the Black Death
A new study sheds fresh light on the long and complex history of the plague by analysing the DNA of the bacterium. Researchers reconstructed 26 genomes of Yersinia pestis from archaeological sites in Estonia, Russia, England, the Netherlands, and Switzerland.
