Project description:Escherichia coli is a common pathogen recovered from cystitis infections. In this report, we announce the draft genome sequence of strain E2 isolated from the urine specimen from a female patient in South Brazil. The genome assembly has 5,081,209 bp, a G+C content of 50.57%, and virulence factors associated with both enteroaggregative and uropathogenic E. coli strains.
Project description:We report the 5.101-Mbp high-quality draft assembly of the Escherichia coli strain ATCC 23506 (serovar O10:K5:H4, also known as NCDC Bi 8337-41) genome. This uropathogenic strain, commonly referred to as E. coli K5, produces N-acetyl heparosan, a glycosaminoglycan-like capsular polysaccharide and precursor to the anticoagulant pharmaceutical heparin. Metabolic reconstruction of this genome will enable the prediction of gene deletions and overexpressions that lead to increased heparosan production.
Project description:Escherichia coli EDL933 is the prototypic strain for enterohemorrhagic E. coli serotype O157:H7, associated with deadly food-borne outbreaks. Because the publicly available sequence of the EDL933 genome has gaps and >6,000 ambiguous base calls, we here present an updated high-quality, unambiguous genome sequence with no assembly gaps.
Project description:We report the 4.682-Mbp high-quality draft assembly of the Escherichia coli strain ATCC 23502 (serovar O5:K4:H4, also known as NCDC U1-41) genome. This uropathogenic strain, commonly referred to as E. coli K4, produces a glycosaminoglycan-like capsular polysaccharide with a backbone similar in structure to unsulfated chondroitin, a precursor to the nutraceutically and potentially pharmaceutically valuable compound chondroitin sulfate. Metabolic reconstruction of this genome will enable prediction of genetic engineering strategies leading to increased chondroitin production.
Project description:We announce the availability of the 5.023-Mbp high-quality draft assembly of the Escherichia coli strain Nissle 1917 (serovar O6:K5:H1) genome. Short genomic segments from this important probiotic strain have been available in public databases, but the full genome sequence has remained inaccessible. Thus, high-coverage, whole genome sequencing of E. coli Nissle 1917 is presented herein. Reannotation and metabolic reconstruction will enable comparative genomics analysis and model-guided predictions of genetic manipulations leading to increased production of the K5 capsular polysaccharide known as N-acetyl heparosan, a precursor to the anticoagulant pharmaceutical heparin.
Project description:Escherichia coli strain BL21 is one of the widely used bacterial hosts for high-level recombinant protein production and for other applications. Here, we present the complete genome sequence of a commercial version of the Escherichia coli BL21 strain.
Project description:We present the complete genome assembly of Escherichia coli ATCC 25922 as submitted to NCBI under accession no. CP009072. This strain was originally isolated from a clinical sample in Seattle, Washington (1946), and is often used in quality control testing. The assembled genome is 5.20 Mb (50.4% G+C content) and includes two plasmids.
Project description:Escherichia coli strain WG5 is a widely used host for phage detection, including somatic coliphages employed as standard ISO method 10705-1 (2000). Here, we present the complete genome sequence of a commercial E. coli WG5 strain.
Project description:Escherichia coli represents the primary etiological agent responsible for urinary tract infections, one of the most common infections in humans. We report here the complete genome sequence of uropathogenic Escherichia coli strain CI5, a clinical pyelonephritis isolate used for studying pathogenesis.
Project description:Enterohemorrhagic Escherichia coli (EHEC) with serotype O157:H7 is a major foodborne pathogen. Here, we report the draft genome sequence of EHEC O157:H7 strain MC2 isolated from cattle in France. The assembly contains 5,400,376 bp that encoded 5,914 predicted genes (5,805 protein-encoding genes and 109 RNA genes).
