title: [Staphylococcal enterotoxin type D: isolation, purification, identification].
abstract: The three step scheme of isolation and purification of staphylococcal type D enterotoxin was elaborated to obtain the homogeneous protein. The scheme includes protein concentration by (NH4)2SO4 saturation and subsequent fractionation on DEAE-cellulose and Sephacryl S-200. The yield of homogeneous protein is 25.5%. The molecular mass of the 29,600 D protein was identified by electrophoresis in polyacrylamide gel in the presence of SDS. The enterotoxic dose for staphylococcal type D enterotoxin is 5 mkg per kg of body mass as identified in experiments with cats. Immunological identity of the obtained protein was established to the commercial preparation of staphylococcal enterotoxin D produced by "Serva".
