Method - injected mice with live, s strain of streptococcus pneumoniae. Method - injected mice with heat-killed s strain of streptococcus pneumoniae. Heat-killed s strain cells are benign, polysaccharides coat itself did not cause pneumonia: experiment. Method - injected mice with a mixture of live r strain cells with heat-killed s strain cells.
