Investigation and Follow-Up of a Staphylococcal Food Poisoning Outbreak Linked to the Consumption of Traditional Hand-Crafted Alm Cheese

Pathogens, 2020
Staphylococcal food poisoning (SFP) is one of the most important foodborne diseases. This work describes a SFP event linked to the consumption of alm cheese and involved three people belonging to the same family. Leftovers of the consumed cheese, samples

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, EarlyView.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...

Laboratory Exposures to Staphylococcal Enterotoxin B

Emerging Infectious Diseases, 2004
Staphylococcal enterotoxins are 23- to 29-kDa polypeptides in the bacterial superantigen protein family. Clinical symptoms from intoxication with staphylococcal enterotoxins vary by exposure route.

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Regulation of staphylococcal enterotoxin B [PDF]

Infection and Immunity, 1977
The effect of glucose and the glucose analogues 2-deoxyglucose and alpha-methyl-glucoside on the synthesis and regulation of staphylococcal enterotoxin B was examined. The attenuating effect of glucose on staphylococcal enterotoxin B synthesis was observed.

Functional and Immunological Studies Revealed a Second Superantigen Toxin in Staphylococcal Enterotoxin C Producing Staphylococcus aureus Strains

Toxins, 2022
Staphylococcus aureus is a human and animal pathogen as well as a commensal bacterium. It can be a causative agent of severe, life-threatening infections with high mortality, e.g., toxic shock syndrome, septic shock, and multi-organ failure. S.

Autosomal Dominant Hyper‐IgE Syndrome Patients Retain IL10‐Producing preTh17‐Cells That Are Activated by Opportunistic Pathogens and Support IgE Production

Allergy, EarlyView.
IL‐10 producing CCR6+Th‐cells are central memory T‐cells that express ROR‐γt and differentiate to Th17‐cells via an autocrine loop of STAT3‐activating cytokines (preTh17). STAT3‐deficient AD‐HIES patients lack Th17‐ and Tfh17‐cells but retain preTh17‐ and Th1/17‐cells.

Subinhibitory concentrations of perilla oil affect the expression of secreted virulence factor genes in Staphylococcus aureus. [PDF]

PLoS ONE, 2011
BACKGROUND: The pathogenicity of staphylococcus aureus is dependent largely upon its ability to secrete a number of virulence factors, therefore, anti-virulence strategy to combat S. aureus-mediated infections is now gaining great interest.

Diet–Microbiome–Immune Interactions at the Gut Mucosa in Food Allergy: Mechanisms, Gaps, and Therapeutic Implications

Allergy, EarlyView.
ABSTRACT Mucosal surfaces are sites of highly dynamic interactions among epithelial and immune cells, environmental exposures, particularly dietary inputs, and the diverse microbial communities and their metabolites. These elements continually influence each other to maintain homeostasis and ensure appropriate immune discrimination between pathogens ...

Binding of Catechins to Staphylococcal Enterotoxin A [PDF]

Molecules, 2018
Staphylococcal enterotoxin A (SEA) is a toxin protein, and is the most common cause of staphylococcal food poisoning. Polyphenols, such as catechins, are known to interact with proteins. In this study, we investigated the binding of catechins to SEA using SPR (Biacore), Fourier transform infrared spectroscopy (FT-IR), isothermal titration calorimetry ...
