[Electrosyneresis in identification of staphylococcal enterotoxins].

Counterimmunoelectrophoresis adjusted on the ground of proteins tested electrophoretic features, is described as a rapid, simple and specific method for staphylococcal enterotoxins identification. This technique has been applied to either purified enterotoxins A, B, and C1 or crude enterotoxins from 196 E, S6 and 137 strains. Enterotoxin-serum reaction takes place in 25 minutes with formation of a precipitation band. Method sensibility moreover allow to use diluted sera and to detect 2 microgram of the purified toxin.
