Isolation of Poliomyelitic Virus from Human Stools.

Summary A virus fulfiling the clinical and pathologic criteria for its identification as poliomyelitic virus has been recovered from the stools from a child with abortive poliomyelitis on the second, fourteenth and twenty-fifth days after onset. This was accomplished twice after intracerebral and intraäbdominal monkey inoculation, and once after intraäbdominal inoculation alone.

Poliomyelitic Virus from Feces in Non-Paralytic Poliomyelitis. II. Infectivity by Various Routes.

Summary The SK. strain of poliomyelitic virus has been shown to be occasionally infectious by the intraperitoneal, intracutaneous, intratonsillar, and oral routes. The Mac. mordax species of monkey, as well as the Mac. cynomolgus, is susceptible to infection with poliomyelitic virus by the oral route.

Identification of a Strain of Poliomyelitic Virus from Feces in Non-Paralytic Poliomyelitis. I. Immunologic Tests.

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.
