Alice Catherine Evans service worker was protected by law. Alice became interested in the disease brucellosis and its relationship to fresh, unpasteurized milk. Alice's investigation focused on the organism "Bacillus abortus", known to cause miscarriages in animals. Alice learned that the microbe thrived in infected cows as well as animals that appeared healthy. The reports hypothesized that since the bacteria was found in cow's milk, a threat to human health was likely. Evans decided to investigate this; she wondered whether the disease in cows could be the cause of undulant fever in humans. She reported her findings to the Society of American Bacteriologists
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
