[Obtaining a specific antigen for the comparative testing of immunological methods in the diagnosis of Marek's disease]. / Poluchavane na spetsifichen antigen za sravnitelno izpitvane na niakoi imunologichni metodi za diagnostika na bolestta na Marek.

ABSTRACT

Comparative studies were carried out on the diagnostic possibilities of immunological methods--precipitation in agar gel, immunofluorescence and indirect hemagglutination, as well as isolation of the virus through primary cellular cultures for the diagnosis of Marek's disease. For the purpose were obtained 9 series of specific antigens. The comparative studies were carried out on fowl and blood serums from different poultry yards, as well as from SPF chickens, experimentally infected with HPRS-16 strain. The results obtained justify a precipitation in agar gels as the most convenient for mass diagnosis of Marek's disease.
