Google Scholar. Next, all of the FASTA files downloaded were then concatenated into one FASTA file containing a list of all of the genes and respective nucleotide sequences from all of the strains being compared. 3. STEC O157:H7 lineage resulted from lateral acquisition of Shiga toxin-encoding bacteriophages, new genomic islands (GI) encoding O157-specific O antigens, and several other GI and bacteriophages impacting virulence and metabolic repertoire of STEC O157:H7 isolates [52, 53, 72, 82]. Results are mean plus the standard deviation of three independent assays. Escherichia coli O157:H7 (O157) has been linked to numerous foodborne disease outbreaks. COVID-19 is an emerging, rapidly evolving situation. 1a). Some of these methods have classified O157 strains into three lineages, human-biased lineage I strains, bovine-biased lineage II strains, and lineage I/II strains, which are ambiguous with respect to host association and phenotype [21, 45, 84]. 1994;272(17):1349–53. The genetic contents, in terms of the total nucleotides constituting the chromosome of NADC 6564 (5.46 Mb), was slightly smaller than the reference strain O157 EDL933 (5.53 Mb) and O157 Sakai (5.49 Mb). In the current study, we performed comparative genomics to determine structural and functional features of the genome of a foodborne O157 isolate NADC 6564 and infer its evolutionary relationship to other O157 strains. Infect Immun. 2011;77(9):2916–25. However, in the tree constructed by comparing concatenated core genome, NADC 6564 appeared to be closely related to lineage I strain EDL933 as these two shared a common ancestral strain. Appl Environ Microbiol. 1995;115(1):1–14. The journal accepts many types of articles such as original reports, expert reviews, editorials, communications, commentaries and letters for publication.

Multiple Species Comparison. 2009;58(3):227–32. In the present study, we used comparative genomics to analyze chromosomal sequence of this isolate, named NADC 6564, to determine its genetic content and organization, unique functional attributes, genetic lineage, and evolutionary relationship to other well-characterized O157 strains. O157 has been called an emerging foodborne pathogen due to the continuous evolution of its genome via acquisition of laterally transferred mobile DNA elements and other mutagenic events [26, 30, 45, 72].
