Quantitative determination of staphylococcal B-type enterotoxin with Laurell's electroimmune diffusion method.
The quantitative determination of B-type enterotoxin produced by Staphylococcus aureus is described. Pretreating the toxin with formaldehyde, the B-type enterotoxin could be demonstrated rapidly with appropriate sensitivity by Laurell's electroimmune diffusion method. Four to eight hours were required for the examination and 0.25 microgram/ml was the smallest demonstrable quantity of the toxin.
