title: [Release of extracellular metabolic products by Streptococci groups C and G].
abstract: 24 group C and 31 group G streptococcal strains were studied examining the production of extracellular nucleases, NADase, hyaluronidase and streptolysin O. 5 mucous strains were characterized by diminished growth and lack of hyaluronidase and NADase-production. Regarding the other strains of group C, one half produced nuclease-activity whereas only one out of ten group G streptococci did. Group G streptococci were more active in the production of NADase and hyaluronidase than group C streptococci. The levels of streptolysin O in groups C and G are comparable.
