Identification of a novel gammaherpesvirus associated with (muco)cutaneous lesions in harbour porpoises (Phocoena phocoena)

Herpesviruses infect a wide range of vertebrates, including toothed whales of the order Cetacea. One of the smallest toothed whales is the harbour porpoise (Phocoena phocoena), which is widespread in the coastal waters of the northern hemisphere, including the North Sea. Here, we describe the detection and phylogenetic analysis of a novel gammaherpesvirus associated with mucocutaneous and skin lesions in stranded harbour porpoises along the Dutch coast, tentatively designated phocoenid herpesvirus 1 (PhoHV1). Phylogenetically, PhoHV1 forms a monophyletic clade with all other gammaherpesviruses described in toothed whales (Odontoceti) to date, suggesting a common evolutionary origin

A novel cetacean adenovirus in stranded harbour porpoises from the North Sea: detection and molecular characterization

Harbour porpoises (Phocoena phocoena) are the most prevalent cetaceans in the North Sea. The fecal viral flora of 21 harbour porpoises stranded along the Dutch coastline was analyzed by a metagenomics approach. Sequences of a novel cetacean mastadenovirus, designated harbour porpoise adenovirus 1 (HpAdV-1), were detected. The sequence of a 23-kbp genomic region, spanning the conserved late region, was determined using primer walking. Phylogenetic analysis indicated that HpAdV-1 is most closely related to bottlenose dolphin adenovirus and clusters with Cetartiodactyla adenoviruses. The prevalence of HpAdV-1 was low (2.6%) based on targeted PCR-screening of the intestinal contents of 151 harbour porpoises stranded between 2010 and 2013
