Brucellosis neurobrucellosis. Brucellosis in humans is usually associated with consumption of unpasteurized milk and soft cheeses made from the milk of infected animals—primarily goats, infected with "Brucella melitensis" and with occupational exposure of laboratory workers, veterinarians, and slaughterhouse workers. Some vaccines used in livestock, most notably "B. abortus" strain 19, also cause disease in humans if accidentally injected. Brucellosis induces inconstant fevers, miscarriage, sweating, weakness, anaemia, headaches, depression, and muscular and bodily pain. The other strains, "B. suis" and "B. canis", cause infection in pigs and dogs, respectively. Definite diagnosis of brucellosis requires the isolation of the organism from the blood,
Brucellosis "reliably" safe as the alternative. In the decades after Evans's work, it was worked out that this genus, which received the name "Brucella" in honor of Bruce, contained several species with varying virulence. The name "brucellosis" gradually replaced the 19th-century names Mediterranean fever and Malta fever. In 1989, neurologists in Saudi Arabia discovered "neurobrucellosis", a neurological involvement in brucellosis. These obsolete names have previously been applied to brucellosis: "Brucella" species were weaponized by several advanced countries by the mid-20th century. In 1954, "B. suis" became the first agent weaponized by the United States at its Pine Bluff Arsenal near Pine
