[Effect of thermal treatment on the properties of staphylococcal enterotoxin type A].
Thermal treatment of staphylococcus enterotoxin of type A at the stage of the cultural fluid failed to influence the character of the enterotoxin purification under the given conditions. In both cases the amount of the removed nitrogen components constituted about 97%. The purified preparations of the staphylococcus enterotoxin of type A differed from one another by the data of electrophoresis and ultracentrifugation and also by the antigenic composition. Under the action of thermal treatment staphylococcus enterotoxin of type A changed its antigenic properties and lost some of its biological activity.
