[Relationship between anti-G-streptococcal titers and the haptoglobin type in human serum--aspects of the observed correlations].
In systematic investigations we found a relationship between the haptoglobin types of human sera and the agglutinability of some group-G streptococcal strains. Sera with the haptoglobin type Hp 1-1 do not agglutinate these strains (or with low titres up to 1:16 only). On the other hand sera with the haptoglobin types Hp 2-1 or Hp 2-2 agglutinate the streptococci with titres from 1:200 to 1:3,200 (or more). The aspects resulting from these findings were discussed in detail. They may have among others practical consequences for the forensic medicine and the role of the haptoglobins must be thought over again.
