[Streptococcus antibodies in various population groups with no apparent signs of streptococcal infection.
Abstract:
ASO- and streptozyme (STZ) antibodies were evaluated in about 2000 subjects: apparently healthy persons, persons in hospital, members of the armed forces, puerperae and their newborns. STZ antigen was found to be more sensitive than ASO; statistically much higher than STZ- and ASO+. The results were coincident (75%-90%) in subjects with normal antibody levels and those with "pathological" titres.
