“…On the basis of a comparison of the B. bronchiseptica IS481 sequences with those of IS481 primers used for conventional PCR identification of B. pertussis (2,3,9,10,12,13,16,18,20,21,23,25,37,45,46,47,53), it seems likely that misidentification of IS481-containing strains of B. bronchiseptica would occur. Many of the suggested primers are 100% identical to the B. bronchiseptica sequence reported here, while others have a few base substitutions which may still permit amplification.…”
