Super-Resolution Imaging of Protein Secretion Systems and the Cell Surface of Gram-Negative Bacteria

Frontiers in Cellular and Infection Microbiology, 2017
Gram-negative bacteria have a highly evolved cell wall with two membranes composed of complex arrays of integral and peripheral proteins, as well as phospholipids and glycolipids.

CRISPR/Cas9‐Assisted Microrobots for Fast and Ultrasensitive “On‐The‐Fly” Next‐Generation DNA Detection

Advanced Functional Materials, EarlyView.
This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

Outer membrane biogenesis in Helicobacter pylori: A deviation from the paradigm

Frontiers in Cellular and Infection Microbiology, 2012
The bacterial pathogen Helicobacter pylori is capable of colonizing the gastric mucosa of the human stomach using a variety of factors associated with or secreted from its outer membrane (OM).

The antimicrobial activity of oil-in-water microemulsions is predicted by their position within the microemulsion stability zone [PDF]

, 2012
It has been shown previously that thermodynamically stable oil-in-water microemulsions have significant antimicrobial activity against planktonic cells and biofilm cells over short periods of exposure. It was the aim of this study to identify whether the

A Novel Mechanism of Host-Pathogen Interaction through sRNA in Bacterial Outer Membrane Vesicles

PLoS Pathogens, 2016
Bacterial outer membrane vesicle (OMV)-mediated delivery of proteins to host cells is an important mechanism of host-pathogen communication. Emerging evidence suggests that OMVs contain differentially packaged short RNAs (sRNAs) with the potential to ...

Small and mighty: adaptation of superphylum Patescibacteria to groundwater environment drives their genome simplicity. [PDF]

, 2020
BackgroundThe newly defined superphylum Patescibacteria such as Parcubacteria (OD1) and Microgenomates (OP11) has been found to be prevalent in groundwater, sediment, lake, and other aquifer environments.

Bioengineering bacterial outer membrane vesicles as vaccine platform [PDF]

Biotechnology Advances, 2017
Outer membrane vesicles (OMVs) are naturally non-replicating, highly immunogenic spherical nanoparticles derived from Gram-negative bacteria. OMVs from pathogenic bacteria have been successfully used as vaccines against bacterial meningitis and sepsis among others and the composition of the vesicles can easily be engineered.

Enhanced Sonodynamic Bacterial Elimination and Wound Healing Therapy Based on Lanthanide Ion Doped Bi2WO6 Nanosheets and Hydrogel Platform

Advanced Functional Materials, EarlyView.
Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...
