Alice Catherine Evans in 1917 and published her work in the "Journal of Infectious Diseases" in 1918. She was met with skepticism, particularly because she was a woman and did not have a Ph.D. She warned that raw milk should be pasteurized to protect people from various diseases. During the 1920s, scientists around the world made the same findings, and eventually, "Brucella" was confirmed as the disease that caused what was then known as undulant fever and Malta fever. Her findings led to the pasteurization of milk in 1930. As a result, the incidence of brucellosis in the United States was significantly reduced.
Swine brucellosis Swine also develop orchitis (swelling of the testicles), lameness (movement disability), hind limb paralysis, or spondylitis (inflammation in joints). Because "B. suis" is facultative and intracellular, and is able to adapt to environmental conditions in macrophages, treatment failure and relapse rates are high. The only effective way to control and eradicate zoonosis is by vaccination of all susceptible hosts and elimination of infected animals. The "Brucella abortus" (rough LPS "Brucella") vaccine, developed for bovine brucellosis and licensed by the USDA Animal Plant Health Inspection Service, has shown protection for some swine and is also effective against "B. suis" infection, but
