Identical Miniature Inverted Repeat Transposable Elements Flank Class 1 Integrons in Clinical Isolates of Acinetobacter spp. Domingues, Sara; Toleman, Mark A.; Nielsen, Kåre M.; da Silva, Gabriela J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Miniature inverted repeat transposable elements (MITEs) have been identified flanking class 1 integrons. We have identified and characterized a 439-bp MITE-like structure in seven Acinetobacter species isolates from Portugal and Brazil. The complete sequence similarity of the elements and flanking regions suggests that MITEs may act as mobilizable vectors for the dissemination of integrons.
Natural Transformation Facilitates Transfer of Transposons, Integrons and Gene Cassettes between Bacterial Species Domingues, Sara; Harms, Klaus; Fricke, W. Florian; Johnsen, Pål Jarle; da Silva, Gabriela J.; Nielsen, Kåre M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)We have investigated to what extent natural transformation acting on free DNA substrates can facilitate transfer of mobile elements including transposons, integrons and/or gene cassettes between bacterial species. Naturally transformable cells of Acinetobacter baylyi were exposed to DNA from integron-carrying strains of the genera Acinetobacter, Citrobacter, Enterobacter, Escherichia, Pseudomonas, ...
