Solubilization and characterization of surface antigenic components of Erysipelothrix rhusiopathiae T28.
The antigenicity of Erysipelothrix rhusiopathiae T28 (serotype 2) was investigated. Antigens were solubilized from the cell surface with detergents. By means of sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting it was shown that the molecular weight of the main antigenic component--a nonprotein--was 14,000 to 22,000. This major antigen was shown to be a polydisperse a...
متن کاملSolubilization and Characterization of a Protective Antigen of Erysipelothrix rhusiopathiae.
A particulate fraction of Erysipelothrix rhusiopathiae cultures has been subjected to butanol extraction and treatment with surface-active agents in an attempt to solubilize a protective antigen. The particulate fraction was partitioned into the butanol layer but was not solubilized. Only sodium dodecyl sulfate solubilized the particles. The soluble protective activity was not sedimented by cen...
متن کاملGenetic and antigenic diversity of the surface protective antigen proteins of Erysipelothrix rhusiopathiae.
The surface protective antigen (Spa) protein of Erysipelothrix rhusiopathiae has been shown to be highly immunogenic and is a potential candidate for a new vaccine against erysipelas. In this study, we cloned and sequenced spa genes from all E. rhusiopathiae serovar reference strains as well as from a serovar 18 strain which was not classified as any species in the genus Erysipelothrix. Sequenc...
متن کاملMechanism of plasma clotting by Erysipelothrix rhusiopathiae.
Experiments were performed to determine the mechanism by which Erysipelothrix rhusiopathiae clots plasma. Detection of plasma-clotting activity in four strains of E. rhusiopathiae was carried out by mixing a 24-h broth culture of a tested bacterial strain with rabbit plasma (tube coagulation test). Sodium citrate, sodium oxalate, EDTA, and heparin were used as anticoagulants in preparing the ra...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
