Abstract

The tdh (thermostable direct hemolysin) gene occurs in some strains of Vibrio species. All tdh genes are flanked by insertion sequence-like elements (ISV). All previous attempts have failed to detect transposition of these ISVs. In this work, we have built a transposition detection system in E. coli and succeeded in detecting the transposition of an insertion sequence-like element at a frequency of Kmr mutants of 7.2 × 10−6. A specific flanking sequence (5′-Py-Pu-3′) was found on either side of the target duplication.
