Paul254 reports on the localization of the virus of poliomyelitis in human beings and on the epidemiology of the disease.
Howe and Bodian255 demonstrated virus in a series of 174 specimens of stools from human beings and chimpanzees. They state that if 2 or more test animals were used the recovery rate would be 90 per cent.
Ward and Sabin256 described 2 patients with poliomyelitis and 1 healthy person from whom poliomyelitis virus had been isolated from the stools in the winter.
Melnick257 describes rod-shaped particles found with a new electron microscope in the stools of patients with poliomyelitis. They were also present in stools from normal patients; it was impossible to say whether these were the specific virus of poliomyelitis or were normal physiologic constituents of stools. Concrete evidence was lacking.
Howe and Bodian258 isolated poliomyelitis virus from the stools of 2 uninoculated chimpanzees
