You should probably give Dr. Patrick Schlievert or Dr. Patrick Cleary at 
the University of Minnesota a call or send a letter. These people have been 
looking at the biology of Group A Strep and Staph (especially Toxic Shock)
toxins for quite a while. I doubt that they are Internet-connected but 
they may be reached care of the Department of Microbiology, University of
Minnesota, 420 Delaware St SE, minneapolis, Minnesota 55455 USA.
