|Categories:||Zoonotic; notifiable diseases and bacteria|
|Etymology:||Genus name: named after Sir David Bruce, who first identified the organism, which causes brucellosis. |
Species epithet: Refers to the island of Malta (Melita), where the organism was first found.
|Type Strain:||16M = ATCC 23456 = NCTC 100|
|Macromorphology (smell):||Pale honey coloured transparant colonies, which do not give hemolysis on blood agar.|
|Micromorphology:||Non-motile cocci or short rods|
|Gram +/Gram -:||G-|
|Other Enzymes:||Urease +|
|Fermentation of carbohydrates:||Most Brucella spp. do not produce acid by fermentation of carbohydrates.|
|Disease:||Brucellosis. Malta fever. The disease is a zoonosis.
Totally two strains have been sequenced, but plasmids have not been reported.
|16S rRNA Seq.:|
||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 melitensis 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.|

|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
