Detection and Characterization of New Coronavirus in Bottlenose Dolphin, United States, 2019 - Volume 26, Number 7—July 2020 - Emerging Infectious Diseases journal - CDC

We characterized novel coronaviruses detected in US bottlenose dolphins (BdCoVs) with diarrhea. These viruses are closely related to the other 2 known cetacean coronaviruses, Hong Kong BdCoV and beluga whale CoV. A deletion in the spike gene and insertions in the membrane gene and untranslated regions were found in US BdCoVs (unrelated to severe acute respiratory syndrome coronavirus 2).
