Through preliminary tests it was established that the treating of lyophilized plague bacteria and their water insoluble residues with organic solvents leads to a sharp lowering of their hemolytic activity. The most pronounced lowering of the hemolytic activity occurred upon treating these preparations with ether, acetone, and n-butanol treating with ethanol produced the least expressed lowering of the hemolytic activity. In this case the water insoluble residues of the plague microbe lost their hemolytic properties rather easily the extracts consisting primarily of free lipids displayed sharply expressed hemolytic properties.
