Numerous marine mammal populations worldwide are declining because of increased anthropogenic and natural threats, including infectious disease. Brucella ceti, morbillivirus, and herpesvirus have been detected from stranded cetaceans and been recognized as pathogens that may result in considerable cetacean morbidity and mortality. Beaked whale circovirus has been reported in multiple cetacean species in Hawaii, USA, and the western Pacific Ocean, but the pathologic relevance in these species remains uncertain. We screened for the presence of Brucella in 66 cetaceans of 17 species that stranded in Hawaii 2000-24 by targeting the insertion sequence 711 partial sequence using PCR.

First Satellite Tag Deployments for Atlantic BRS 2024
July 8, 2024
In June 2024, a Duke University team initiated the Atlantic Behavioral Response Study (BRS) by deploying satellite-linked dive recorders on goose-beaked whales (Cuvier's beaked whales) off the coast of North Carolina. These tags collect data on the whales' diving behavior and locations, enhancing understanding of their baseline activities. Additionally, the team released a rehabilitated hawksbill sea turtle named Bagheera back into the Atlantic Ocean.
