The first human case of Brucella abortus (porcine) infection to be reported was described by Keefer1 from the Biological Division of the Johns Hopkins Hospital. Cultures of the stools were negative. Because of failure to isolate the organism from the stools in this case, the stools in two other unusual cases of Brucella infection to be reported have received scant attention and no positive stool cultures have been described in the numerous cases on record since Keefer's paper appeared.
Organisms of the Brucella group have been observed2 only once in the feces of man but there are no reports of successful cultivation from this source. Bruce2 states that "they probably pass out of the body by way of the alimentary canal." The organisms have been found frequently in the urine not only in cases of malta fever (10 per cent in 3,000 cases) but also in Brucella
