Brucellaceae
Brucellaceae
Brucellaceae (pronounced: broo-sell-uh-see-ee) is a family of Gram-negative bacteria, known for their role in causing brucellosis, a zoonotic disease affecting various mammals.
Etymology
The name Brucellaceae is derived from the genus Brucella, which was named after the British army physician David Bruce, who first isolated and identified the bacteria.
Description
Members of the Brucellaceae family are small, non-motile, non-spore-forming, rod-shaped bacteria. They are facultative intracellular parasites, meaning they can survive and multiply within host cells. The family includes two genera: Brucella and Ochrobactrum.
Brucella
The Brucella genus includes several species, such as Brucella abortus, Brucella melitensis, Brucella suis, and Brucella canis, each of which is associated with a different animal host and has a slightly different disease presentation in humans.
Ochrobactrum
The Ochrobactrum genus is less well-studied, but some species have been associated with human disease, particularly in immunocompromised individuals.
