An automated image analysis framework for segmentation and division plane detection of single live Staphylococcus aureus cells which can operate at millisecond sampling time scales using bespoke Slimfield microscopy [PDF]

, 2016
Staphylococcus aureus is an important pathogen, giving rise to antimicrobial resistance in cell strains such as Methicillin Resistant S. aureus (MRSA). Here we report an image analysis framework for automated detection and image segmentation of cells in S. aureus cell clusters, and explicit identification of their cell division planes.

A Novel Approach to Produce Metal–Metal Composites by Leveraging Immiscibility: Laser Powder Bed Fusion of Nanosilver‐Dispersed Titanium

Advanced Engineering Materials, EarlyView.
Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Clinical, Microbiological, and Genetic Characteristics of Heteroresistant Vancomycin-Intermediate Staphylococcus aureus Bacteremia in a Teaching Hospital [PDF]

, 2014
The emergence of vancomycin intermediate Staphylococcus aureus (VISA) and heterogeneous VISA (hVISA) is of major concern worldwide. Our objective was to investigate the prevalence, phenotypic and molecular features of hVISA strains isolated from ...

Adhesive properties of film-forming strains of staphylococci, isolated from different compartments of the human gastrointestinal tract

Regulatory Mechanisms in Biosystems, 2017
Dysbiotic disorders, realized as changes in the composition of microbiota of different biotopes, are among the most difficult conditions to cure. This is due primarily to the fact that opportunistic microorganisms that actually mediate the development of

Gene replacement in Staphylococcus carnosus and Staphylococcus xylosus [PDF]

FEMS Microbiology Letters, 1997
A system for high-efficiency gene replacement in Staphylococcus carnosus and Staphylococcus xylosus has been developed, that is based on temperature-sensitive Escherichia coli-Staphylococcus shuttle vectors for fragment delivery and erythromycin resistance cassettes to facilitate selection of genomic copies of disrupted genes.

Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

Advanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

The Frequency of MRSA carriers in health care workers in Gorgan, North of Iran [PDF]

, 2011
Methicillin resistant Staphylococcus aureus (MRSA) is one of the most important pathogen in hospitals. Healthcare personnel are the main source of nosocomial infections and identification and control of MRSA carriers can reduce incidence of infections ...

Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

Advanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

Staphylococcus Aureus Infection

Definitions, 2020
There are many different strains of staph. Some strains are resistant to the antibiotic called methicillin, and often other antibiotics as well. This is called methicillin resistant Staphylococcus aureus (MRSA) and is more difficult to treat.

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

Advanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.
