Data on the link between genomic integration of IS and lineage of the strain obtained by bioinformatic analyses of sequenced genomes of available at the National Center for Biotechnology Information database.

IS, a 1316-bp element of the IS family affects the expression of several genes of the opportunistic pathogen Furthermore, certain lineages of are more frequently associated to particular diseases than other [1, 2]. We took advantage of the release of the genome sequences of a huge number of epidemiologically unrelated strains of various origin to analyze the prevalence of IS among strains. To this end, genome available at the National Center for Biotechnology Information (NCBI) database were blasted with IS DNA sequences. A sequence type (ST), based on the allelic profile of seven housekeeping genes, was assigned to each strain possessing IS. These strains were then grouped into clonal complexes (CCs). The data obtained will give the opportunity to compare the sequenced genomes of based on their lineage and/or possession of IS, and to select the corresponding strains for comparative experimental studies. The data is related to the research article « Dual and divergent transcriptional impact of IS insertion upstream of the peptidoglycan biosynthesis gene of " [2].
