Abstract
Summary
Strains of virus, recovered from the stools of a child (SK.) with nonparalytic poliomyelitis, produced typical experimental poliomyelitis in Mac. rhesus monkeys. This SK. strain appears to be related immunologically to other strains of poliomyelitis virus recovered from the same epidemic, and to be related to the Aycock strain of 1920, and to some Californian strains of 1934. On the other hand, there appears to be at least some immunologic difference between the SK. strain and the Park strain, two eastern strains of 1931, and strains from Toronto and Cleveland of 1937.
The SK. strain produced no corneal reaction in rabbits and no consistent type of infection on intracerebral inoculation into rabbits, guinea pigs, and Swiss mice.
These tests yield further evidence, in addition to that already reported, 1 that the SK. strain is an example of poliomyelitic virus.
