Background: Staphylococcal superantigens (SAg;aposs) may have some role in otitis media with effusion (OME). The aim of this study was the search of staphylococcal SAg;aposs in middle ear effusion of children with OME.  Methods: This cross sectional-analytic study was done in ENT & pediatric wards upon 64 children with otitis media with effusion (OME) between 1-15 years, (mean age=7.42+4 years)...

Change in the Expression of BAK، FAS، BAX، TNF-A، BCL-2 and Survivin Apoptosis Genes of the Human Breast Adenocarcinoma Cells (MCF-7) by Staphylococcal Enterotoxin B

Introduction: Breast cancer is one of the most prevalent malignancies among women. Patients whose suffering from this condition, as a result of the use of conventional therapies often have a poor response to treatment and the relapse among them is frequent. In this study, the effects of staphylococcal enterotoxin type B on BAK، FAS، BAX، TNF-a، BCL-2 و Survivin genes expression in human breast ...

Identification of bacterial antigens and super antigens in synovial fluid of patients with arthritis: a cross sectional study

  Background : An accurate and prompt diagnosis of bacterial arthritis is essential for earlier treatment and a good outcome. Superantigens produced by Staph. Aureus are among the most lethal toxins. The paper objective was Identification of common bacterial antigens and S.aureus superantigens in synovial fluid (SF) of children with negative culture and direct smear for other bacteria except fo...

Staphylococcal Enterotoxin B and Related Pyrogenic Toxins

Pyrogenic specificity of streptococcal exotoxins, staphylococcal enterotoxin, and gram-negative endotoxin.

Streptococcal exotoxin and staphylococcal enterotoxin share several biological properties, including pyrogenicity, lymphocyte mitogenicity, and enhancement of gram-negative endotoxin lethality. These analogies of the toxins prompted comparative pyrogenic studies. When American Dutch rabbits were immunized by repeated intravenous injections of small amounts of staphylococcal enterotoxin, they ex...
