INFECTIOUS MOTOR PARALYSIS IN YOUNG XXXX .

@entity1 @entity3328 @entity66 @entity840 @entity95 @entity11101 @entity912
1. The attempt to infect young @entity95 and @entity840 with material containing in all probability the virus of @entity1 @entity3328 failed. 2. Failure to infect the primary animals almost of necessity brought failure with the secondary @entity11101 -bitten animals. It is, however barely conceivable that a non-infectious form of an organism might circulate in the blood of the primary animal and that this form, through development in an intermediate host, the @entity11101 , might become virulent for the secondary @entity11101 -bitten animal. 3. Incidentally, and presumably accidentally, a @entity66 was observed in young @entity95 associated with the presence of an organism showing certain definite characters. So far as we know this @entity912 and the associated organism have not been previously described. 4. This organism is found widely distributed in the organs of the affected animals and can be demonstrated in the urine. The active destruction by the organism of the nerve cells of the spinal cord is particularly striking, and gives complete explanation for the @entity912 observed clinically. 5. With the organism present in the urine the spread of the disease by contact can be easily understood. 6. The transfer of the infection from animal to animal by fleabites is possible but not probable. 7. The nature of the observed organisms is in doubt. They represent probably an intermediate stage in the life history of some protozoan parasite.
