During an outbreak goats developed neutralizing antibodies without manifesting clinical symptoms or lesions. Presence of virus neutralizing antibodies in 5 of the 10 kids born up to 8 weeks after actual disappearance of the outbreak, suggested the possibility of virus survival in some undetermined source up to at least 2 months of the post-outbreak period. Study of neutralizing antibody level in 3 goats after artificial infection revealed peak titers on 7, 11 and 12 post-infection days followed thereafter by a gradual decline. In one goat the antibodies were demonstrable as early as 3 days after infection.
