title: Isolation of two Brucella abortus biotypes from tissues of a naturally infected cow.
abstract: Brucella abortus biotypes 1 and 2 were recovered from various tissues of a naturally infected cow. This result indicates a need for biotyping multiple isolates of B. abortus from several affected animals in a herd before the biotype of the infecting strain can be definitively established.
