| Abstract: | Nine adult or young chickens of different flocks naturally exposed to avian encephalomyelitis virus were moved to the laboratory at a very early stage of the exposure and kept separately. Then they were observed for the rise and fall of neutralizing antibody against the virus up to 14～34 months after they had been moved. Two birds with the antibody titers of log neutralization indices of 3.0 and 4.5 showed almost the same titers after 21 months. Seven birds with slightly positive or negative antibody titers (0.6～2.0) at initial stage scarcely gave higher titer during the experiment. Two of the birds became negative after the 5th or 11th month of the observation period. Three birds observed for 30～34 months maintained low but significant levels of antibody with or without intermittent appearances of negative titers. |
