Abstract: A strain named SCBI-1, isolated from a sick pig was diagnosed by cultural characteristics and morphologic observation with its pathogenicity studied by mice virulent experiment and was accurately identified by biochemical assay and the analysis of 16S rDNA sequence. Drug resistance was analysed by sensitive assay. Homology of the 16S rDNA between SCBI-1 and Bordetella bronchiseptica is 99.3-99.9%, the study successfully isolated a strain of Bordetella bronchiseptica which could lead a mouse to death within 16 h and is resistant to penicillin, rifampicin, clindamycin, ampicillin and cefalotin.
