| Taxonomy/phylogeny:
|
Eleven species have been described within genus Brucella and this genus is closely related to genus Bartonella. From a phylogenetic point of view, B. abortus, B. canis, B. ceti, B. melitensis, B. neotome, B. ovis, B. pinnipedialis and B. suis represent the same species (B. melitensis), but due to different host specificities, they have been affiliated with different species. | ||||||||
| Legislation: | Brucella suis belongs to category B as a potential bioterrorism agent according to NIAID. | ||||||||
| Comment: | May penetrate intact skinn. In Sweden brucellosis is notifiable to the Swedish Board of Agriculture and is governed by the epizootic diseases law. | ||||||||
