Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Intermittent antibiotic exposure of Escherichia coli biofilms drives resistance in catheter-associated infection models

npj Biofilms and Microbiomes
The use of antibiotic lock therapy (ALT) to protect catheters from infection is still being debated due to its inconsistent effectiveness and the potential risk of promoting antibiotic resistance.

Biofilm released cells can easily be obtained in a fed-batch system using ica+ but not with ica- isolates [PDF]

PeerJ, 2020
Staphylococcus epidermidis is one of the major opportunistic bacterial pathogens in healthcare facilities, mainly due to its strong ability to form biofilms in the surface of indwelling medical devices.

3D‐Printable, Biodegradable, and Conductive/Piezoionic Hydrogel ‘E‐Skin’ With Robust Antibacterial Properties for Wound Healing and Wireless Human‐Machine Interface Sensing

Advanced Functional Materials, EarlyView.
A multifunctional MXene‐integrated GelMA/alginate hydrogel reinforced with TEMPO‐modified nanocellulose is engineered via dynamic covalent, ionic, and hydrogen bonding. The resulting piezoelectric, adhesive, antimicrobial, and 3D‐printable patch enables motion sensing and accelerates wound healing by promoting keratinocyte migration and collagen ...

Acid tolerance in early colonizers of oral biofilms

BMC Microbiology, 2021
Background In caries, low pH drives selection and enrichment of acidogenic and aciduric bacteria in oral biofilms, and development of acid tolerance in early colonizers is thought to play a key role in this shift.

To Build a Biofilm [PDF]

Journal of Bacteriology, 2003
Development is not restricted to so-called higher organisms. Developmental processes in bacteria include differentiation of a single cell, such as the swarmer-to-stalk transition by Caulobacter crescentus and spore formation by Bacillus subtilis .

Advancements in Hypersaline Wastewater Treatment: The Promise of Quasi‐Liquid Surfaces to Reduce Salt Scaling

Advanced Functional Materials, EarlyView.
Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...

Cells released from S. epidermidis biofilms present increased antibiotic tolerance to multiple antibiotics [PDF]

PeerJ, 2019
Biofilm released cells (Brc) are thought to present an intermediary phenotype between biofilm and planktonic cells and this has the potential of affecting their antimicrobial tolerance.
