Mengo encephalomyelitis virus
Dick, George W. A.
Twenty years ago the various human encephalitides then known, (excluding poliomyelitis and rabies), were listed by Rivers (1) as (a) Von Econ_omo's lethargic, (b) following vaccination, (c) Japanese 1924, (d) Koritschoner and (e) Australian X disease. At that time from none of these dis- eases had a virus been recovered. In 1930 the viruses of louping ill (2) and Western equine encephalitis (3) were isolated. During the past two decades an additional 17 primary or suspected encephalitic viruses of man have been recovered.Of these recently isolated agents the following have been recovered at the Yellow Fever Research Institute, Entebbe, Uganda: -West Nile (4), Bwamba Fever (5), Bunyamwera (6), Semliki Forest (7), Mengo encephalomyelitis (8), and Uganda S (9) viruses.It is the purpose of this thesis to describe the isolation of Mengo encephalomyelitis virus and to discuss the properties of this agent and its relationship to the virus of encephalomyocarditis (10) and to the Columbia SK (11) and MM viruses (12).
