Brucella is a genus of Gram-negative bacteria. They are small (0.5-0.7 × 0.6-1.5 µm), non-motile, encapsulated coccobacilli. Slow-growing, Brucella species require complex media for isolation.
Brucella is the cause of Brucellosis, a true zoonotic disease (i.e. no human-to-human transmission has been identified). It is transmitted by ingesting infected food, direct contact with an infected animal, or inhalation of aerosols. Minimum infectious exposure is between 10 - 100 organisms. Brucellosis primarily occurs through occupational exposure (e.g. exposure to cattle, sheep, pigs), but also by consumption of unpasteurised milk products.
