Genome Sequence:
Acc-noStrainSize (bp)Genome
NC_010103 and NC_010104 ATCC 23365T 3 312 769 2c + 0 
Chrom. I (2 105 969 bp) and chrom. II (1 206 800 bp), respectively.

16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
L37584 (T) 1 418 
Two rRNA genes in chrom. I and one in chrom. II.

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.

"Dear child has many names" (call it what you will...)

For a long time, Rhodococcus hoagii was refer­red to Rhodo­coccus equi on VetBact, because we experienced some resistance to the name that is now considered to be the correct one, i.e. Rhodococcus hoagii. Now you can find the bacterium in question under the correct name in VetBact, but you can also find the bacterium when searching for the old name.
