Résumé : Two Erwinia chrysanthemi homologues of the himA and himD genes of Escherichia coli which encode the integration host factor (IHF) were cloned, sequenced and compared to their homolog in other enterobacteria (EMBL accession nos X74749 and X74750). Both genes were inactivated by the insertion of an antibiotic resistance cassette, allowing for the isolation of IHF- mutants of E chrysanthemi.
