Brucella ceti is an emerging zoonotic pathogen that has been recovered from several species of cetaceans in the world's oceans over the past 20 yr. We report the recovery of B. ceti from a Sowerby's beaked whale (Mesoploden bidens) and a long-finned pilot whale (Globicehala melas). Recovery from the testis of a long-finned pilot whale provides further evidence of potential for B. ceti infection to impact the reproductive success of cetaceans, many of which are threatened species. The addition of another two cetacean species to the growing number from which B. ceti has been recovered also further emphasizes the concern for human infections with this organism.
