PHENOMENON OF LOCAL SKIN REACTIVITY TO BACTERIAL FILTRATES: AN ANTIBODY AUXILIARY TO SERUM NEUTRALIZATION OF MENINGOCOCCUS REACTING FACTORS

摘要

In. this paper there is described an antibody auxiliary to the neutralization of meningococcus reacting factors. The presence of the antibody facilitates studies on neutralizing potency of antimeningococcus sera. There is also reported a non-specific neutralizing factor of a heterologous immune serum, which can be differentiated from specific neutralizing antibodies of antimeningococcus sera. Its nature and connection with the auxiliary antibody remain to be determined.
