An attempt was made to select slightly virulent strains by consecutive passages in cell cultures and use of extreme dilutions applying the temperature test (heating up to 50 degrees C for 1 hour). Initial and final fractions were compared for lethality and pruritus on rabbits and studied by the plate method. Levelling of the cytopathogenic titer after heating heated and unheated virus was achieved in laboratory samples isolated from lungs, and in two strains -- isolated from brains. This was… Expand
