Abstract: | We constructed and screened a gene bank of phase I chromosomal DNA of Bordetella pertussis in Escherichia coli. A single immunopositive clone was recovered, and the hybrid plasmid obtained, designated pFSH200, had a molecular size of 46.6 kilobases. Smaller derivatives were generated by partial digestion of plasmid pFSH200 and were further characterized. One such derivative, plasmid pFSH201, contained a 4.5-kilobase chromosomal DNA fragment of B. pertussis which coded for the synthesis of the two outer membrane proteins of 33 and 30 kilodaltons specific to B. pertussis. |
