Clostridium botulinum

Clostridium botulinum strains produce botulinum neurotoxin, which is the cause of foodborne botulism.

Data Downloads

The Sanger Institute has completed the sequence of the genome of Clostridium botulinum, in collaboration with Dr. Roger Huston of the Food Microbial Sciences Unit, University of Reading Department of Food Science, Dr. Nigel Minton of the Institute of Infection, Immunity and Inflammation, University of Nottingham, and Dr. M. Peck of the Food Saftey Microbiology Section, Institute of Food Research.

Published Genome Data

We have sequenced Hall strain A (ATCC 3502) and Eklund 17B. The genome of Hall strain A (ATCC 3502) is 3,886,916 bp in size, with a G+C content of approximately 28.2%. There is also a plasmid of 16,344 bp. The completed sequence for both strains is available for searching on our Blast server, or for download from our FTP site. This project is funded by Beowulf Genomics.

The fully annotated genome and plasmid are available of Hall strain A (ATCC 3502) are available from the EMBL/GenBank databases with accession numbers AM412317 and AM412318 respectively.

Shotgun and assembly data from this project are available from our FTP site.

Data Use Statement

This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
