Structural and biological properties of protein toxins that have received the name of staphylococcus pyrogenic toxins (PTSAg) are presented. Data regarding genetic regulation of secretion and synthesis of these toxins and 3 main regulatory genetic systems (agr - accessory gene regulator, xpr - extracellular protein regulator, sar - staphylococcal accessory regulator) that coordinate synthesis of the most important protein toxins and enzymes for virulence of S. aureus, are presented.</p></abstract><trans-abstract xml:lang="ru"><p>Анализируются основные научно-исследовательские работы, касающиеся белковых бактериальных токсинов наиболее распространенных бактерий, относящихся к роду Staphylococcus spp. и, в частности, наиболее патогенного для человека вида Staphylococcus aureus. Представлены структурные и биологические свойства белковых токсинов, получивших название пирогенных токсинов стафилококка (PTSAg), сведения, касающиеся генетической регуляции секреции и синтеза этих токсинов, и три основные регуляторные генетические системы (agr - accessory gene regulator, xpr - extracellular protein regulator, sar - staphylococcal accessory regulator), которые координируют синтез важнейших для вирулентности белковых токсинов и ферментов S. aureus.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Staphylococcus aureus</kwd><kwd>enterotoxins</kwd><kwd>toxins</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>энтеротоксины</kwd><kwd>токсины</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Вертиев Ю.В.
