RESUMO
Dye-binding assays were employed to study the effects of penicillin on the production of hyaluronidase and deoxyribonuclease by a group C streptococcal strain. Enzymatic activities were measured in supernates of bacterial cultures that had been exposed to low concentrations of the drug during growth. The addition of antibiotic resulted in an increase in the production of hyaluronidase and in a decrease in that of deoxyribonuclease. These alterations in the elaboration of extracellular substances and their release into the frowth environment could be of importance as the Streptococcus is affected in vivo during treatment with penicillin.
