The plaque reduction neutralization test PRNT is currently the most ejcefalitis used in vitro test. SLEV is widely distributed throughout the western hemisphere; however, strains isolated in the United States and Canada are apparently more virulent than those isolated in the Caribbean and Central and South America 4.
