Biofilm Control by Active Topography with Mucin Coating

Advanced Functional Materials, EarlyView.
This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...

A preceding low-virulence strain pandemic inducing immunity against COVID-19 [PDF]

arXiv, 2020
Countries highly exposed to incoming traffic from China were expected to be at the highest risk of COVID-19 spread. However, COVID-19 case numbers (infection levels) are negatively correlated with incoming traffic-level. Moreover, infection levels are positively correlated with population-size, while the latter should only affect infection-level once ...

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Helicobacter pylori in Iran: a systematic review on the association of genotypes and gastroduodenal diseases [PDF]

, 2012
Background: Helicobacter pylori (H. pylori) infection is known as a major etiologic factor for a variety of gastroduodenal diseases. In Iran, with a high rate of H. pylori infection close to 90%, numerous studies have revealed many aspects of interaction

Virulence factors of uropathogenic Escherichia coli (UPEC) and correlation with antimicrobial resistance

BMC Microbiology, 2019
Escherichia coli has found to be the predominant uropathogen (50–90%) in uncomplicated, community acquired urinary tract infection (UTI). Uropathogenic Escherichia coli (UPEC) express a multitude of virulence factors, which enable the bacteria to ...

Implication of Sialidases in Salmonella Infection: Genome Release of Sialidase Knockout Strains from Salmonella enterica Serovar Typhimurium LT2. [PDF]

, 2017
Sialidases, which are widely distributed in nature, cleave the α-ketosidic bond of terminal sialic acid residue. These emerging virulence factors degrade the host glycan.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Synergistic Effects of Nanoparticle Heating and Amoxicillin on H. Pylori Inhibition [PDF]

, 2019
We report the design and development of a dual-functional magnetic nanoparticle platform for potential treatment of H. pylori infection. We show that an ultralow concentration of Mn0.3Fe2.7O4@SiO2 nanoparticles subjected to a moderate AC magnetic field, without bulk heating effect, can deposit heat locally and effectively inhibit H.

Importance of Virulence Factors for the Persistence of Oral Bacteria in the Inflamed Gingival Crevice and in the Pathogenesis of Periodontal Disease

Journal of Clinical Medicine, 2019
Periodontitis is a chronic inflammation that develops due to a destructive tissue response to prolonged inflammation and a disturbed homeostasis (dysbiosis) in the interplay between the microorganisms of the dental biofilm and the host.

Synthetic Mucus Biomaterials Synergize with Antibiofilm Agents to Combat Pseudomonas aeruginosa Biofilms

Advanced Therapeutics, EarlyView.
Mucus‐inspired biomaterials are developed that inhibit biofilm formation and enhance dispersal when combined with DNase and/or α‐amylase. The combination led to up to 2‐log reductions in biofilm viability, offering a promising alternative to traditional antibiotics for treating persistent, antibiotic‐resistant infections.
