Detection of IdeS activity in bacterial culture media. An aliquot of bacteria-free media harvested from a culture of S. pyogenes isolate AP1 growing in Todd-Hewitt broth at different times was assayed for IdeS activity as described in the Methods. Control samples harvested at the time of inoculation (0 hours) were included in each assay.
