[Antidesoxyribonuclease B-titer in persons of different ages and sex and comparative studies of antistreptolysin titers].

The antidesoxyribonuclease B reaction shows in persons of all classes of age examined a similar distribution of titres as the antistreptolysin reaction. The anti DNase B titres however are mostly lower than the titres of the antistreptolysin reaction, except in the group of children, 6 to 17 years of age, suffering frequently from latent infections of streptococci. Women in childbed showed lower anti DNase B titres than other persons of corresponding age. Among persons with anti DNase B titres higher than antistreptolysin titres predominate men.
