Abstract

Transposon Tn5 was introduced into Legionella pneumophila on plasmid pRK340, which is temperature sensitive for plasmid maintenance. The presence of plasmid DNA was confirmed by agarose gel electrophoresis and by conjugal transfer of the plasmid to Escherichia coli. Tn5 insertions were obtained by culturing L. pneumophila at the nonpermissive temperature (43 degrees C) on buffered charcoal-yeast extract agar containing kanamycin. Of the 260 kanamycin-resistant colonies picked, 220 failed to conjugate pRK340 to E. coli. Plasmid DNA was not visualized from eight randomly picked Tn5-containing strains, and Southern hybridizations indicated that Tn5, but not pRK340, inserted into multiple sites in the Legionella chromosome. In addition, the streptomycin resistance determinant on Tn5 was expressed in L. pneumophila.
