Brucella can also target the male reproductive tract. [7] Globally, an estimated 500,000 cases of brucellosis occur each year. [7]

Brucellosis is a zoonotic disease: marine mammal brucellosis can infect other species, including human beings. Brucella spp. are gram-negative in their staining morphology. Brucella spp. are poorly staining, small gram-negative coccobacilli (0.5-0.7 x 0.6-1.5 μm), and are seen mostly as single cells
Humans can become infected if they have contact with an infected animal or its byproducts. Animals acquire B. melitensis by venereal transmission. [1] The organism is found in blood, urine, milk, and semen. [1] It is zoonotic, unlike B. ovis, causing Malta fever or localized brucellosis in humans. Brucella melitensis colonies growing on agar
