title: Immunological activity against tick-borne encephalitis virus in fractions of sera from goats of different ages.
abstract: A comparative analysis of the antihaemagglutinating, virus-neutralizing and complement-fixing activities of 19 S, 7 S, 4S and 1.5 S fractions of blood sera from goats of different ages pastured in a tick-borne encephalitis focus was carried out. Changes in the immunological activity of different fractions in relation to the age of the animals are discussed.
