"Brucella is a genus of Gram-negative bacteria, named after David Bruce (1855-1931). They are small (0.5 to 0.7 by 0.6 to 1.5 \u00B5m), non-encapsulated, flagellated, facultatively intracellular coccobacilli.Brucella is the cause of brucellosis, which is a zoonosis. It is transmitted by ingesting contaminated food (such as unpasteurized milk products), direct contact with an infected animal, or inhalation of aerosols."@en . . . . . . . .
