Abstract

The detection of Bordetella bronchiseptica which is supposed to be an agent of the infectious atrophic rhinitis of swine, is likely to receive more attention in the future as the pork industry comes to realize that eradication of this infection from breeding herds is a practical possibility. Experiments described here were carried out to establish the rapid plate agglutination test for the detection of the infectious atrophic rhinitis of swine in the field using the criteria of antigen preparation, effects on the antigenecity after storing of the antigen and reaction appearing time. Also, the agglutinabilities between the plate and tube method were compared and the degree of pathological lesions were recorded in relation to tube agglutination titers. Obtained results were as follows: 1. No differences were noted in the agglutinabilities on the plate agglutination test between the treatments in antigen preparation-formolized, merthiolate-killed and living organism. 2. The agglutinability of the antigens did not show any significant changes until 10 weeks of storage at 4 C; however, after 10 weeks of storage, non-specific reaction was observed with the HPCD control sera. 3. The results of the plate and tube agglutination tests were not comparable but the effective use of the plate method in Bordetella bronchiseptica eradication programs in pigs especially in the sow is stressed as a screening test.
