Abstract

Summary

Strains of and were examined by immunological methods for their ability to degrade the human serum proteins IgG, IgM, C3 and C5. The proteolytic activity of the strains was measured in terms of the breakdown of serum into trichloroacetic acid-soluble material. Only black-pigmented strains showed proteolytic activity. Strains of degraded IgG, IgM, C3 and C5, strains of IgG and C3, strains of C3 and IgG and a strain of degraded only IgG. These findings are discussed in relation to the pathogenicity of the black-pigmented
