title: Mercury resistance determinants related to Tn21, Tn1696, and Tn5053 in enterobacteria from the preantibiotic era.
abstract: Three mer transposons from the Murray collection of preantibiotic enterobacteria show >99% sequence identity to current isolates. Tn5073 is most closely related to Tn5036 and Tn1696, and Tn5074 is most closely related to Tn5053. Tn5075 is most closely related to Tn21 but lacks integron In2 and is flanked by insertion elements.
