The present investigation describes the biological and biochemical properties of a persistent SSPE virus infection. Persistently infected cells were derived by cocultivation of infected brain cells and uninfected Vero cells, and cultures were maintained by normal subculturing methods. No infectious virus was ever released from these cultures, and all(More)
The presence of measles cytotoxic (CT) and hemagglutination inhibition (HI) antibodies in 195 multiples sclerosis (MS) patients and 251 controls was tested. The measles virus Lu carrier cells labeled with 51Cr were exposed to serum specimens in the presence of complement in order to test the presence of CT antibody. The analysis of complement dependent CT(More)
The serological responses of 195 multiple sclerosis (MS) patients and 251 controls were tested against 6/94-parainfluenza virus, which was previously isolated from brain tissue of two patients with MS. The hemagglutination-inhibition titers of ≥1:128 were found more frequently in MS patients (21.5%) than in controls (14.0%). However, the geometric mean(More)
