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.
Brucellosis are high incidences of abortions, arthritic joints, and retained placenta. The two main causes for spontaneous abortion in animals are erythritol, which can promote infections in the fetus and placenta, and the lack of anti-"Brucella" activity in the amniotic fluid. Males can also harbor the bacteria in their reproductive tracts, namely seminal vesicles, ampullae, testicles, and epididymes. The causative agent of brucellosis in dogs, "B. canis", is transmitted to other dogs through breeding and contact with aborted fetuses. Brucellosis can occur in humans who come in contact with infected aborted tissue or semen. The bacteria in dogs normally infect the
