NewsSmart wound dressing delivers antibiotics on-demand, accelerating healing and reducing resistance
Biomedical engineers have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound. The material could help rapidly clear wound infections to accelerate healing while reducing the unnecessary use of antibiotics.

NewsNew drug candidate extremely effective against H. pylori bacterium
Researchers have discovered that metronidazole targets two central protective proteins of Helicobacter pylori: an enzyme responsible for detoxifying harmful reactive oxygen species and a protein that repairs damaged proteins.

NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsAntibiotics can affect the gut microbiome for several years
Researchers have found strong links between a person’s history of antibiotic use and the composition of their gut microbiome, including the diversity of bacterial species.

NewsUltrasound-activated ‘nanoagents’ kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug‑delivery capsules – carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound.

NewsTrust your gut to heal your brain
Researchers have found that short-term antibiotic treatment significantly reduced neuroinflammation and neurodegeneration following traumatic brain injury (TBI) by altering the gut microbiome in animal models.

NewsEmerging class of antibiotics to tackle global tuberculosis crisis
Researchers investigated how three naturally occurring antibiotic compounds – ecumicin, ilamycin and cyclomarin – act on a vital protein degradation machine inside Mycobacterium tuberculosis, the bacterium that causes TB.

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.

NewsShorter treatment regimens are safe options for preventing active tuberculosis
A study comparing one- and three-month antibiotic treatments to prevent active tuberculosis (TB) finds that a high percentage of patients successfully completed both regimens and suffered few adverse side effects.

NewsWhat drives food allergies? New study pinpoints early-life factors that raise risk - including microbiome
A new study involving 2.8 million children around the world has revealed the most important early-life factors that influence whether a child becomes allergic to food. Genetics alone cannot fully explain food allergy trends, pointing to interactions between genes, skin health, the microbiome, and environmental exposures.

NewsClinical data gaps keeping life-saving antibiotics from children
Antibiotics that could treat severe infections in babies and children aren’t accessible due to a lack of data around safety and dosage. Of 12 antibiotics recommended for serious bloodstream infections caused by a harmful, Gram-negative bacteria, only six were licensed in children aged under 12 and just three in babies.

NewsAntibiotic therapy: is shorter just as effective?
Shorter-duration antibiotic therapy shows comparable success to longer-duration treatment in children with community-acquired pneumonia. However, a general conclusion about a shortened treatment duration is not possible, Tthe authors of a new study say.

NewsHow a potential antibiotics ban could affect apple growers
Antibiotic resistance in human and animal health is on the forefront of public debate, but it’s a less well-known issue in plant agriculture. However, antibiotics are important tools in fruit production, and their efficacy hinges on avoiding resistance in disease-causing bacteria. Source: Tianna DuPont, WSU Extension Apple ...

NewsPine bark removes pharmaceutical residues from wastewater – an affordable way to keep antibiotics out of nature
Researchers have developed a pine‑bark–based water‑treatment medium that efficiently removes antibiotics as well as residues of blood‑pressure and antidepressant medicines from wastewater treatment plant effluent.

NewsWhy don’t antibiotic-making bacteria self-destruct?
Scientists discovered a promising new antibiotic in a soil sample. The molecule, lariocidin, is produced by the microbe Paenibacillus and shows broad activity against pathogenic bacteria. Now, the researchers report how Paenibacillus avoids harm by its own antibiotic.

NewsResearchers revive failing antibiotics with two-faced Janus nanoparticles
Researchers have restored the power of failing antibiotics by combining them with two-sided nanoparticles, ultra-small building blocks of materials less than 100 nanometers across. The nanoparticles showed a remarkable ability to compromise bacterial cell walls, leaving them vulnerable to attack.
-
NewsNew test shows which antibiotics actually work
Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor is whether the active substances actually kill the pathogens in the body. Researchers have presented a new method for measuring how effectively antibiotics kill bacteria.

NewsAntibiotics in sediments may quietly boost greenhouse gas emissions
A study shows that pharmaceutical pollution alters nitrogen cycling and greenhouse gas emissions in coastal sediments. Even environmentally relevant antibiotic concentrations increased N₂O release, suggesting that widespread contamination may enhance estuarine climate forcing.

NewsResearchers use robotics to find potential new antibiotic among hundreds of metal complexes
Researchers have used a cutting-edge robotic system capable of synthesising hundreds of metal complexes to develop a possible antibiotic candidate - offering fresh hope in the global fight against drug-resistant infections.

NewsThe antibiotic delafloxacin emerges as a potential therapeutic alternative against Legionella
A study shows, in an experimental laboratory model, that delafloxacin inhibits the intracellular replication of Legionella more effectively than one of the current standard treatments.
