Enzyme Immunoassay for Staphylococcal Enterotoxin A

Journal of AOAC INTERNATIONAL, 1980
Abstract An enzyme immunoassay procedure specifying alkaline phosphatase-labeled enterotoxin A was used to determine enterotoxin in standardized solutions and food extracts. Staphylococcus aureus Cowan 1 cells were used to separate unbound from antibody-bound enterotoxin.

Staphylococcus aureus enterotoxins modulate IL-22-secreting cells in adults with atopic dermatitis

, 2018
Atopic dermatitis (AD) is a chronic inflammatory immune-mediated skin disease characterized by skin colonization by Staphylococcus aureus. Interleukin (IL)-22, in cooperation with IL-17, triggers antimicrobial peptide elaboration and enhances certain ...

Basis of Virulence in Enterotoxin-Mediated Staphylococcal Food Poisoning

Frontiers in Microbiology, 2018
The Staphylococcus aureus enterotoxins are a superfamily of secreted virulence factors that share structural and functional similarities and possess potent superantigenic activity causing disruptions in adaptive immunity.

Serologic Studies of Staphylococcal Enterotoxin [PDF]

Public Health Reports (1896-1970), 1958
THE NEED for a simple and specific technique for demonstrating and assaying staphylococcal enterotoxin has been recognized for a long time. Research efforts ranging from biological tests with small and relatively cheap animals (1, 2) to extensive chemical and serologic studies of enterotoxin (3) have not attained this important objective.

Molecular Study of Enterotoxin Genes of Staphylococcus aureus Isolated Locally from Al-Diwaniyah City

Medical Journal of Babylon
Background: Following Salmonella, Staphylococcus aureus has been identified as the second most frequent origin of foodborne disease outbreaks. It was discovered that there are five main forms of enterotoxins, named the classic staphylococcal enterotoxin ...
