[Structural similarity and functional activity of molecular fragments of staphylococcal enterotoxin B and thymopoietin II].

Structural similarity between Staphylococcus enterotoxin B and a thymus hormone, thymopoietin, has been revealed concerning thymopentin, one of active centres of thymopoietin. Fragments of enterotoxin B homologous to thymopoietin and their analogues were synthesized their immunological activity studied. Acetyl derivative of the fragment 225-229 of enterotoxin B increased infectional resistance and stimulated delayed type of hypersensitivity reaction.
