| Enhanced Production of Cell-Bound and Extracellular Streptolysin S by Hemolytic Streptococci Pretreated with Proteases  | | | | Abstract
| The amount o f streptolysin S produced by resting streptococci was considerably increased after incubation o f the washed bacteria with trypsin or pronase. Production o f both cell-bound and free forms o f the toxin was enhanced by the protease treatment. By addition o f trypsin, streptolysin S yield was considerably increased in growing culture as well. Treatment with lysozyme was ineffective, and the toxin production was only slightly prom oted by preincubation with hyaluronidase or Chymotrypsin. In contrast, pretreatment with chymotrypsin caused in creased production o f an extracellular nuclease, whereas the yield o f this enzyme was reduced after incubation o f the cocci with pronase. Evidence was obtained indicating de novo synthesis o f the exotoxin in the protease-treated bacteria. | | | |
