Encephalitogenous

As regards the first point, we only found the encephalitogenous salivary virus twice out of thirteen cases examined.

The salivas containing the virus are divided by the authors into keratogenous and encephalitogenous, according as their inoculation on the rabbits cornea produces a simple corneal pustule or transmits encephalitis to the animal.

As antigens were used both human encephalitogenous protein and an antigen from sarcoma of bone associated with the tumor.

Veratti and Sala's suggestion agrees with the observations of Doerr and Schnabel and Levaditi, Harvier, and Nicolau on carriers of the herpetic and encephalitic virus, and with those of Danila and Stroe regarding certain encephalitogenous but not keratogenous viruses.

Eighty per cent of healthy persons have a keratogenous salivary virus which is identical with the herpetic and encephalitic viruses. In fifteen per cent of persons, besides the keratogenous salivary virus, there is also a kerato-encephalitogenous virus which is in all points similar to von Economo's virus.

The addition of encephalitogenous factor and egg albumin to MS plasma liberates serotonin but does not do so in control subjects; in MS cases encephalitogenous factor is more active than egg albumin.
