News‘Controlled evolution’ dramatically boosts pDNA production for biomedical manufacturing
Researchers have controlled the evolution of E. coli bacteria in the lab in order to dramatically increase the amount of plasmid DNA (pDNA) these modified bacteria produce. pDNA is an essential – and expensive – ingredient in many gene therapies.

NewsNew hydrogel-based treatment accelerates infected wound healing and balances skin microbiota
A novel ε-poly-L-lysine-loaded sodium-alginate/gelatin hydrogel (PSG15) has shown exceptional promise in accelerating the healing of infected wounds. The injectable hydrogel delivers antibacterial properties while regulating macrophage polarization and stabilizing the skin microbiota.

NewsEnvironmental antibiotic resistance unevenly addressed despite growing global risk, study finds
Antibiotic resistance in the environment is a growing and largely overlooked crisis receiving inconsistent attention, according to a new study. Worryingly few studies have explored how antibiotic resistance spreads in the air, oceans or green spaces.

NewsSmall protein, big impact: Insights into how bacteria stabilize a key outer membrane complex
Researchers reveal that a remarkably small protein is essential for the maturation of a component of the lipopolysaccharide transport system.

NewsLavender steps up as a natural preservative in skin-care emulsions
A new study shows that blends of lavender essential oil and hydrosol can replace synthetic preservatives in oil-in-water creams, cutting microbial counts by >99 % without irritating skin.

NewsHospital superbugs that cause sepsis and meningitis could be hitching a ride on mobile phones
Hospital superbugs that cause sepsis and meningitis could be hitching a ride on mobile phones, allowing them to escape out of healthcare settings and into the community, according to research presented at MLS Future Forum earlier this year.

NewsSmart bandage with ‘plant power’ heals chronic wounds faster than market leaders
A multidisciplinary team has unveiled a next-generation wound dressing that behaves like a living leaf yet fights like a miniature pharmacy. It combines neomycin-grafted cellulose nonwovens with a polyvinyl alcohol/cellulose-nanofiber aerogel dyed with blueberry anthocyanins.

NewsMicrobially synthesized bioplastic may solve marine plastic pollution problem
Researchers have demonstrated a new eco-friendly plastic that decomposes in deep ocean conditions. In a deep-sea experiment, the microbially synthesized poly(d-lactate-co-3-hydroxybutyrate) (LAHB) biodegraded, while conventional plastics persisted.

NewsBacteriostatic activity and mechanism of minerals containing rubidium
A new paper on traditional Chinese medicine outlines the bacteriostatic activity and mechanism of minerals containing rubidium (MCR).

NewsDisease-causing bacteria can deal with stink as long as they get a meal
Bacteria that cause intestinal infections typically avoid a stinky chemical — one that can kill them at high enough concentrations — inside human intestines, but they may actually swim toward it when a hearty meal is the reward.

NewsAI finds hundreds of potential antibiotics in snake and spider venom
Researchers used a deep-learning system to sift through a database of more than 40 million venom encrypted peptides (VEPs). In a matter of hours, the algorithm flagged 386 compounds with the molecular hallmarks of next-generation antibiotics.

NewsFlightpath Biosciences licenses microbiome-sparing antibiotic developed at Illinois
Flightpath Biosciences, Inc., has licensed a class of antibiotics developed at the University of Illinois Urbana-Champaign. The original antibiotic agent, lolamicin, effectively treated bacterial infections in animal models of disease without wiping out beneficial gut microbes.

NewsMultiresistant intestinal bacteria: Displacement through food competition
Researchers made use of food competition to figure out how potentially dangerous multi-resistant bacteria could be effectively removed from the gut before reaching the bloodstream and causing serious problems.
-
NewsGreen light activates this antibiotic only where it’s needed
To make a more efficient antibiotic treatment, researchers have modified penicillin so that it’s activated only by green light. In early tests, the approach precisely controlled bacterial growth and improved survival outcomes for infected insects.

NewsNew study reveals global warming accelerates antibiotic resistance in soils
A new international study has revealed that climate change is accelerating the rate of development and global abundances of antibiotic resistance bacteria in soils.
-
NewsNew source of natural antibiotics hidden within our own proteins identified
A team of scientists has identified a new type of antimicrobial peptides (AMPs) found in human proteins that are capable of selectively eliminating multidrug-resistant bacteria, particularly of the gram-negative type, responsible for serious hospital acquired infections.

NewsResearchers reveal remarkable antimicrobial activity in hydrogen boride nanosheets
Hydrogen boride (HB) nanosheets represent an exciting new frontier in the search for technologies that can combat microbes in everyday settings. Researchers discovered that they exhibit excellent antibacterial, antiviral, and antifungal properties.

NewsCan gut microbes save patients from chemotherapy side effects?
Intestinal microbes that survive chemo can rid the gut of excess chemo drugs and produce a vitamin that helps to stem nausea, a new study reveals.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsScientists evaluate in-vitro activity of ceftazidime-avibactam against carbapenem-resistant gram-negative bacteria
Scientists explored the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria collected at the outpatient, emergency, and inpatient departments of the Indus Hospital, Karachi.
