Theiler's encephalomyelitis virus Theiler's encephalomyelitis virus Theiler's Murine Encephalomyelitis Virus (TMEV) is a single-stranded RNA murine cardiovirus from the family "Picornaviridae". It has been used as a mouse model for studying virally induced paralysis, as well as encephalomyelitis comparable to Multiple sclerosis. Depending on the mouse and viral strain, viral pathogenesis can range from negligible, to chronic or acute encephalomyelitis. The virus was discovered by virologist Max Theiler in 1937 while working at the Rockefeller Institute. Theiler discovered the encephalomyelitis virus during research on poliovirus-like paralysis symptoms in mice. That year Theiler had completed work on developing a vaccine for Yellow Fever, for
