Herpesviruses (HVs) ( and subfamilies) have been detected in several species of cetaceans with different pathological implications. However, available information on their presence in beaked whales (BWs) is still scarce. In this study, a total of 55 BWs (35 and 20 animals belonging to the genus) were analyzed. Samples ( = 294) were obtained from BWs stranded along the coasts of the Canary Islands (1990-2017). Molecular detection of HV was performed by means of a conventional nested PCR based on the DNA polymerase gene. Herpesvirus was detected in 14.45% (8/55) of the analyzed BWs, including 2 positive animals from a previous survey. A percentage positivity of 8.57% was found within the Cuvier's BW group, while the percentage of positivity rose to 25% within the genus group (three one , and one ). All the obtained sequences from this study belonged to the subfamily, from which three are considered novel sequences, all of them within the genus group. In addition, to our knowledge, this is the first description of HV infection in Gervais' and Sowerby's BWs. Three out of eight HV-positive BWs displayed histopathological lesions indicative of active viral replication.
疱疹病毒（HVs）（及其亚科）已在几种鲸类动物中被检测到，具有不同的病理学意义。然而，关于它们在喙鲸（BWs）中存在的现有信息仍然很少。在本研究中，共分析了55头喙鲸（35头属于 属，20头属于 属）。样本（n = 294）取自加那利群岛沿岸搁浅的喙鲸（1990 - 2017年）。通过基于DNA聚合酶基因的常规巢式PCR进行疱疹病毒的分子检测。在14.45%（8/55）的分析喙鲸中检测到疱疹病毒，包括之前调查中的2头阳性动物。在柯氏喙鲸组中发现阳性率为8.57%，而在 属组中阳性率升至25%（三头 ，一头 ，一头 ）。本研究获得的所有序列均属于 亚科，其中三条被认为是新序列，均在 属组内。此外，据我们所知，这是首次对热尔韦氏喙鲸和索氏喙鲸的疱疹病毒感染进行描述。8头疱疹病毒阳性喙鲸中有3头表现出指示活跃病毒复制的组织病理学病变。
