|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.|
|New names of taxa within the classification category phylum|
