Dear MARMAM community, My co-authors and I are pleased to share our most recent publication entitled: *Molecular detection of herpesvirus in a skin lesion of a humpback whale (Megaptera novaeangliae) from the Western Mediterranean Sea*.
You will find the open access publication at the *link*: https://link.springer.com/article/10.1007/s10344-024-01782-7 *Abstract*:Herpesvirus has the potential to infect a wide variety of animal species. In cetaceans, *Alp*ha- and/or *Gammaherpesvirinae* have been identified in eight families of odontocetes, and one family of mysticetes. In May 2022, an adult humpback whale (*Megaptera novaeangliae*) was found stranded in Valencia, Spain. The whale was emaciated, in poor body condition, with multiple lacerations on the dorsal fin and a high number of epibionts of the Cyamidae family, known as whale lice. The individual had been previously released from a ghost net entanglement 5 days before becoming stranded. In a closer examination, various skin lesions were observed, including chronic, proliferative, and erosive dermatitis and a large ulcer extending to the deep dermis. As part of the infectious disease surveillance programme, molecular testing was performed on skin samples for herpesvirus, cetacean morbillivirus, and poxvirus. A positive result for herpesvirus was obtained from one of the skin lesions. The sequence was found to belong to the *Alphaherpesvirinae *subfamily, and it was closely related to alphaherpesvirus sequences from a fin whale (*Balaenoptera physalus*) and a humpback whale. Cetacean morbillivirus and poxvirus testing was negative. To the authors’ knowledge, this is the first report of herpesvirus in a humpback whale from the Mediterranean Sea. Reports on herpesvirus detection or infection in humpback whales (only species within the genus *Megaptera*) are scarce. In consequence, future virological assessments of humpback whales should include testing for herpesvirus. Please do not hesitate to contact us for any questions you may have.
