STAPHYLOCOCCUS ENTEROTOXIN B-M

葡萄球菌Staphylococcus

-enes group）、乳酸菌共同的性质，但其毒性非常强，移植于动物血管中可引起动物体各处发生脓疡，而表现出严重的症状以至死亡。然而与人皮肤脓疡类似的种类不易在动物体上发生，只有极少数的可在类人猿和兔发生类似的症状。因乳制品和肉类的腐败而出现的中毒，认为多由此类细菌引起，原因是葡萄球菌在增殖过程中可产生肠毒素（ enterotoxin）。这种毒素的生物活性在于能刺激呕吐中枢产生催吐作用。该细菌是抗菌物质中毒和一般营养不良时成为次级的微生物区系的主要细菌。从黄色葡萄球菌的细胞壁分离出的蛋白质 A可与免疫

T-Lymphocyte Activation Induced by Staphylococcal Enterotoxin Superantigens: Analysis of Protein Tyrosine Phosphorylation

Staphylococcus enterotoxin superantigens (SAgs) have the capacity to strongly activate oligoclonal populations of T lymphocytes expressing T-cell antigen receptors (TCR) that share particular Vβ elements. These superantigens stimulate T

T-Cell Cytotoxicity Assays for Studying the Functional Interaction Between the Superantigen Staphylococcal Enterotoxin A and T-Cell Receptors

The superantigens (SAgs) staphylococcal enterotoxins (SEs) are produced by certain strains of Staphylococcus aureus and comprise structurally related bacterial proteins, which are among the most potent mitogens known for murine and human T
