Brucellosis is not only of concern to the veterinarian from the standpoint of animal health; it also concerns the Veterinary Profession from the standpoint of public health. In dealing with brucellosis in animals, the veterinarian must be ever on his guard-lest he himself become infected with the serious malady commonly termed undulant or malta fever. From the standpoint of public health, chief reliance is placed on members of the Veterinary Profession in the pursuit of measures for the control and eradication of brucellosis in cattle, swine and other susceptible animals.
