Anti-bacterial and anti-adhesion effects of marine Glycomyces sediminimaris against the dental plaque biofilm-forming Streptococcus mutans – An in vitro study

The Microbe
This investigation reports the potent anti-biofilm activity of Glycomyces sediminimaris UTMC 2460 (DSM 103727), a marine-derived actinobacterium, against Streptococcus mutans which is among etiological agents of dental plaque formation and related oral ...

Anti-biofilm, drug delivery and cytotoxicity properties of dendrimers

ADMET and DMPK
Background and purpose: Treatments using antimicrobial agents have faced many difficulties as a result of biofilm formation by pathogenic microorganisms. The biofilm matrix formed by these microorganisms prevents antimicrobial agents from penetrating the interior where they can exact their activity effectively.

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

Animal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

BMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

Limits to growth and what keeps a biofilm finite

, 1999
Two of the factors, shear erosion and diffusive mass transfer, which limit the growth of heterogeneous biofilms are considered. For permeable beds of particulates, with a regulated throughflow, equating shear induced erosion and biofilm growth, leads to ...

Staphylococcus aureus Biofilm-Associated Infections: Have We Found a Clinically Relevant Target?

Staphylococcus aureus is one of the most diverse bacterial pathogens. This is reflected in its ability to cause a wide array of infections and in genotypic and phenotypic differences between clinical isolates that extend beyond their antibiotic ...

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Comparative evaluation of planktonic and biofilm modes of growth in Salmonella Typhimurium [PDF]

, 2011
In this research, comparative studies of planktonic and biofilm modes of growth in Salmonella enterica serovar Typhimurium were undertaken. Chemical disinfectant studies were performed for both planktonic and biofilm Salmonella and biofilms at different ...
