Abstract
In this pilot study, we investigated the relative avidities for streptococc al pyrogenic exotoxin A (SPE-A) and SPE-B of antibodies in sera from patien ts,vith fatal streptococcal toxic shock-like syndrome and from healthy indi viduals and in intravenous immunoglobulin (MG) preparations. We observed a great variation in the relative avidities of patient, control, and MG immun oglobulin G (IgG) (values estimated to be between 10(-7) and 10(-11) M), wi th mean values for patient IgG about 10-fold lower than those of control Ig G.
