title: [Nucleotide sequences of mercury resistance determinants in bacteria isolated from mercury mines: detection of a family of recombinant mercury transposons in plasmids from Acinetobacter species].
abstract: Partial nucleotide sequences were determined for mer operons located on large and small plasmids previously described in Acinetobacter spp. isolated from different mercury mines of the USSR. Inspection of the sequences shows that: 1. All Acinetobacter mer operons studied belong to a family of transposons homologous to transposons found in clinical isolates. 2. The transposons located on the small plasmids originated by recombinations between the transposons from the large plasmids and Tn501, a transposon found in a Pseudomonas hospital strain isolated in Australia. The left arm of each hybrid transposon was donated by a transposon of a large Acinetobacter plasmid and the right arm - by the Tn501.
