Abstract
A mild clinical syndrome in Macacus rhesus, accompanied by pathologic changes in the sensory portions of the vagus ganglia, intervertebral ganglia, and sometimes in the Gasserian ganglia is described. This syndrome occurred following intraperitoneal inoculation of fecal material obtained from contacts and from patients with infantile paralysis in an epidemic in a rural community. When intranasal as well as intraperitoneal inoculation was practiced, the olfactory bulbs were sometimes involved.
