The Sanger Institute has been funded by the Wellcome Trust to sequence the genomes of two Bacteroides fragilis, strains NCTC9343 and 638R, in collaboration with Sheila Patrick (Queen's University of Belfast, UK), Garry Blakely (University of Edinburgh, UK), Val Abratt of the Department of Molecular anf Cell Biology at the University of Cape Town (South Africa), Prof. Brian Duerden (University of Wales College of Medicine, UK) and Prof. Ian Poxton (University of Edinburgh Medical School, UK).
Published Genome Data
Published Sequence
We have sequenced, annotated and analysed the complete genome of the type strain NCTC9343 (ATCC 25285). The genome is 5,205,140 bp long, with a G+C content of 43.19%. The data are available for download by FTP and can be searched using our BLAST server. The annotated data are also available from EMBL/GenBank with accession number CR626927.
We have also sequenced, annotated and analysed the complete genome of strain 638R. The data from strain 638R are available for download by FTP and can be searched using our BLAST server. The sequence is 5,373,121 bp with a G+C content of 43.42%. The shotgun data are still available: There are 81,661 reads in the database, totalling 46.520 Mb, and giving a theoretical coverage of 99.99%. The annotated data are also available from EMBL/GenBank with accession number FQ312004.
