POLIOMYELITIS BY ACCIDENTAL CONTAGION IN THE CHIMPANZEE.
Poliomyelitis virus was isolated from the stools of two uninoculated chimpanzees which had been quartered for 6 months in cages adjoining those of rhesus monkeys receiving intranasal inoculations of potent human stools. Upon arrival, and for 4 months thereafter, neither chimpanzee had antibody against the virus eventually isolated from it. However, antibody had developed against the animals' own virus strains at the time these were isolated from the feces.
