The current nomenclature for C. botulinum recognises four physiological groups ( I-IV ).
The classification is based on the ability of the organism to digest complex proteins.
Studies at the DNA and rRNA level support the subdivision of the species into groups I-IV.
Most outbreaks of human botulism are caused by group I ( proteolytic ) or II ( non-proteolytic ) C. botulinum.
Group III organisms mainly cause diseases in animals.
There has been no record of Group IV C. botulinum causing human or animal disease.
