Preparation Of Monospecific Antisera Against Fowl Cholera, Fowl Coryza And Newcastle Disease Reference Strains In Laboratory Animals [electronic resource].

Includes references.

Monospecific antisera against Pasteurella multocida strains that belonged to capsular and somatic serogroups A:1, A:3 and A:4, Avibacterium paragallinarum serovars A and C and Newcastle disease virus, were prepared in three separate rabbit groups for each using reference bacterial and viral cultures emulsified in Freund's adjuvant. Antisera of P. multocida were qualitatively and quantitatively evaluated by serological tests using their homologous and heterologous antigens (cross matching). Sera of immunized rabbits showed a reasonable titre of P. multocida capsular group (A) antibodies by passive haemagglutination test and to somatic serotype (A) 1, 3 and 4, antibodies by tube agglutination and agar gel diffusion tests. Serovars A and C antibodies of Avibacterium paragallinarum were detected in sera of the immunized rabbits by plate agglutination test.
