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,
A2 milk is impossible to determine what component or components of milk might be responsible for these effects, and it is unlikely that the expensive and complex research to determine the answers to these questions will ever be conducted. Milk with predominantly A2 protein is not a milk substitute for infants with cow milk protein allergies. The a2 Milk Company claims that people who experience discomfort drinking ordinary cows' milk may experience relief when they switch to milk with predominantly A2 protein. In the 1980s, some medical researchers began to explore whether some peptides (including peptides from casein) that are created during
