Sir David Bruce isolated B. melitensis from British soldiers who died from Malta fever in Malta.After exposure to Brucella, humans generally have a two- to four-week latency period before exhibiting symptoms, which include acute undulating fever (>90% of all cases), headache, arthralgia (>50%), night sweats, fatigue, and anorexia.

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
