[The antiviral activity of RNAse Bacillus intermedius in experiments with mice preinfected with street rabies virus].

RNAse Bacillus intermedius, when administered once and according to 11 repeated experiments, protected the preliminarily infected CBA mice with street rabies virus (protection of 40-67%; p < 0.01-0.001). A reliable protection of Animals was registered only when RNAse was administered intramuscularly at the virus introduction spot; it was not effective, when the bacterial RNAse was injected in the brain, vein, under the skin or in muscles of a non-infected extremity. Neither did it produce any suppressive effect on the vaccinal antirabic immunity.
