Alphaherpesvirus: Isolation, Identification, Partial Characterisation, Associated Pathologic Findings and Epidemiology in Beluga Whales (Delphinapterus leucas) in Alaska and Arctic Canada

Abstract: Live, dead stranded, and harvested belugas (Delphinapterus leucas) in Alaska and the western Canadian Arctic were screened for viruses utilizing a primary beluga cell line. Samples consisted of swabs from blowhole, anus, and genital tract. Virus cytopathic effect was seen after the incubation of 6-30 days post infection, and virus-like particles consistent with herpesvirus were observed upon electron microscopy. DNA extraction, cetacean-specific polymerase chain reaction (PCR) amplification, and sequencing of … Show more

“…Our observations support the previous case reports of erosive‐to‐ulcerative skin lesions caused by a herpesvirus infection in belugas (Burek‐Huntington et al, 2015; Nielsen et al, 2018). Not all ulcers, however, are caused by an herpesviral infection; out of eight macroscopically ulcerated skin lesions, seven were negative for herpesvirus.…”

“…Not all ulcers, however, are caused by an herpesviral infection; out of eight macroscopically ulcerated skin lesions, seven were negative for herpesvirus. Surprisingly, the amplicons from the genome of the herpesvirus detected in this study had 100% homology to the equid gamma-herpesvirus 2, whereas an alpha-herpesvirus has been previously detected in cutaneous and mucosal lesions (Bellehumeur et al, 2015;Nielsen et al, 2018) and isolated from a blowhole swab (Davison et al, 2017) et al, 2009). Antibodies against a gamma-herpesvirus have been detected in belugas from the Sakhalin-Amur beluga stock (Alekseev et al, 2017).…”

“…Beluga research and monitoring has evolved over the past 40 years, responding to community questions, management needs and scientific investigations that have brought together a community of knowledge-holders working collaboratively to best study beluga. Beluga harvest monitoring has revealed a declining trend in size-at-age of male beluga in the Mackenzie Estuary from 1993 to 2007 (Harwood et al 2015); dietary shifts and impacts on dive physiology (Choy et al 2017;Choy et al 2019;Choy et al 2020); trends in contaminants (Loseto et al 2015;Noel et al 2018); microplastics in beluga (Moore et al 2020); and diseases (Nielsen et al 2018;Sharma et al 2018). Community members are part of the planning and field crews, sometimes participate in laboratory analyses (typically youth) and often are part of the dissemination of results at meetings and conferences.…”
