Abstract

The black bear, Ursus americanus Pallas, has been found to he an exceptionally good host for a common species of Diphyllobothrium, as evidenced by the large size attained by individual strobilae, and the duration of infections experimentally established. Since 1950, the writer has used at least five of these bears annually in the study of Diphyllobothrium spp. With the single exception reported herein, no adverse effect to the hosts has been recognized.
