In this follow-up to their article published the previous year on the specific soluble substance, or SSS, Avery and Heidelberger concluded that the pneumococcus cell possesses at least two distinct substances which are directly concerned with the organism's biological specificity. Their research suggested that one of these substances, which they termed the polysaccharide of pneumococcus, was not only serologically reactive, but unlike the protein of pneumococcus, was type-specific, and therefore could identify a particular variant of pneumonia.
