Ochrobactrum is a bacterial genus that belongs to Brucellaceae in the Rhizobiales. The genus has been described by Holmes in 1988 and Ochrobactrum anthropi was proposed as the type species of the genus. Further work led to the recognition of 16 other species, for a total of 18:
- Ochrobactrum anthropi
- Ochrobactrum ciceri
- Ochrobactrum cytisi
- Ochrobactrum daejeonense
- Ochrobactrum gallinifaecis
- Ochrobactrum grignonense
- Ochrobactrum guangzhouense
- Ochrobactrum haematophilum
- Ochrobactrum intermedium
- Ochrobactrum lupini
- Ochrobactrum oryzae
- Ochrobactrum pecoris
- Ochrobactrum pituitosum
- Ochrobactrum pseudintermedium
- Ochrobactrum pseudogrignonense
- Ochrobactrum rhizosphaerae
- Ochrobactrum thiophenivorans
- Ochrobactrum tritici
The Ochrobactrum strains are all Gram-negative short rods, straight or slightly curved with one end flame shaped. The cells are approximately 0.6-1.2 to 2 μm in length. They are non-spore forming, strictly aerobic and non-fermentative.
The genomes of most Ochrobactrum species is complex with two independent circular chromosomes often associated to plasmids.
