Absorption of Endogenous Pyrogens by Bentonite.

Abstract

Endogenous pyrogen (E. P.) in serum from animals given endotoxin or Newcastle disease virus and in leukocytic exudates was inactivated by absorption with bentonite. Concentration of lysozyme in serum and exudates paralleled that of E. P. The pyrogenicity of typhoid vaccine and NDV was not affected by absorption with bentonite.
