Nano-biotechnological approach for the ultrasensitive electrochemical and fluorescence detection of Staphylococcal enterotoxin B

Materials Research Express
Staphylococcus aureus , a bacterium with gram-positive characteristics and a spherical shape, is typically harboured in the human nose and skin. It can survive at a wide range of temperatures (15 °C to 45 °C), has virulence factors, and contains toxins ...

Thermal Inactivation of Staphylococcal Enterotoxins B and C [PDF]

Applied Microbiology, 1973
Thermal inactivation profiles of staphylococcal enterotoxins B (SEB) and C (SEC) at 80, 100, and 121 C showed that SEC is more resistant than SEB to heat. After 24 h of incubation at 25 C, some reactivation (recovery of serological reactivity) occurred in toxins that had been inactivated by heat.

Prevalence and Genomic Characterization of mcr‐Positive Enterobacteriaceae in Retail Meat in Thailand Following the Colistin Ban

Microbiology and Immunology, EarlyView.
ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

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.

Staphylococcal Enterotoxins, Stayphylococcal Enterotoxin B and Bioterrorism

, 2012
Staphylococcal enterotoxins (SEs) are exotoxins produced primarily by Staphylococcus aureus, which is a ubiquitous microorganism with world-wide distribution (Bergdoll, 1983; Dinges et al., 2000). SEs are a major cause of food poisoning and they are also potent immune activators that lead to serious immune dysfunction (Alouf and Muller-Alouf, 2003 ...

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 ...

Mitogenicity of formalinized toxoids of staphylococcal enterotoxin B [PDF]

Infection and Immunity, 1975
Staphylococcal enterotoxin B is a potent mitogen for mouse and human lymphocytes. Mitogenic activity was retained after detoxification of the enterotoxin by formaldehyde at pH 5.0, 7.5, OR 9.5. The most active toxoid (pH 7.5) was separated into a monomeric, a dimeric, and a polymeric fraction (1 x 10(5) to 3 x 10(5) molecular weight) by gel filtration,

Differential segment‐specific signalling pathways for guanylate cyclase C‐activated anion secretion in murine ileocolon

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.

Effect of carbohydrate substrates on growth and enterotoxin gene expression in Bacillus cereus (pacificus)

Scientific Reports
Bacillus cereus sensu lato is a common contaminant of improperly stored food and human milk, capable of causing severe emetic and diarrheal diseases, particularly in infants and immunocompromised individuals.
