Abstract excerpt
The aroA gene from Pasteurella multocida serotype A:1 (X-73) was cloned by complementation of the Escherichia coli aroA mutant AB2829 with a DNA library constructed in pUC18. The cloned aroA gene was inactivated by deletion of a 300 bp internal sequence and reintroduced by homologous recombination into the chromosome of X-73 and P-1059 (serotype A:3) using a Pasteurella-E. coli shuttle vector pPBA1100.
