We demonstrate that transposon-mediated mutagenesis can be used to construct mutations in the pathogen Brucella abortus. We have used both a plasmid and a bacteriophage to introduce either Tn5 or Tn5 lac into the Brucella chromosome. B. abortus is naturally sensitive to kanamycin. We have selected 22 independent kanamycin-resistant colonies in strain US-19 and 19 colonies in strain 2308. We have demonstrated by Southern hybridization that Tn5 was inserted into the chromosome.
