Two hundred and foaen sera samples firm two groups of rabbit were subol to determination of atophic rhinitis antibody by agglutination test. Forty-eight (44%) outofl09fromgroupAwerepothtive(1:10)inARantibody, whi]e31 outof 103 from group B were positive (29.3%). The total poGitive rate was 36.9% (79/21 4).

Fifen random samples and 30 samples from rabbit with dini,oal signs (sneer et) nary were collected by use of nasi swabi, and oiltnsi for isolation of Bordetella bronsohiseptica. Sera were also collesotei from the same rabils for AR antibody detection. The baxoteria (B. bronchisep&a) were isolated from l0out of the 13 random samples and 29 out of the 30 samples (rabbit withdinical signs),while like the antibody pothtive rate was 40%(611 3) and 86.7%(26/30), respectively. The bioterial isolates did prcduce dermoneiorotic toxin when demonstrated on guinea-pigs, The result indicated that the rabbit population in Taiwan was higly oo’ntaminatl with Bordetella honchiseptica, i.e. Atrophic rhinitis..
