During their last quarter as veterinary students many members of the Class of '49 expressed interest in their personal status with regard to brucellosis. Information of this sort seemed desirable at this time since the chance of contracting brucellosis would increase upon graduation and engaging in practice. Knowledge of the presence or absence of reaction to brucellosis might in some cases aid in diagnosis in the event of future illnesses.
