An adult male striped dolphin (Stenella coeruleoalba) stranded alive at Arico, Tenerife, Canary Islands, Spain. The dolphin died shortly after stranding, and a complete postmortem examination was performed. The most remarkable gross findings were two fleshy masses of approximately 1 cm diameter, near the tip of the penis. These masses were composed of hyperplastic epithelial cells with pigmentary incontinence. Ballooning degeneration and margination of chromatin was observed within the stratum corneum of the epidermis. A universal nested PCR assay that amplifies a conserved region within the polymerase gene of Herpesviridae was positive. The sequenced product was most closely related to a gammaherpesvirus that shared nucleotide identities of 93% with penile lesions from Atlantic and Mediterranean bottlenose dolphins (Tursiops truncatus). This similarity supports the hypothesis of sexual transmission between species.
一只成年雄性条纹海豚（宽吻海豚属）在西班牙加那利群岛特内里费岛的阿里科搁浅，搁浅时还活着。这只海豚在搁浅后不久死亡，并进行了完整的尸检。最显著的大体检查结果是在阴茎尖端附近有两个直径约1厘米的肉质肿块。这些肿块由增生的上皮细胞组成，伴有色素失禁。在表皮角质层内观察到气球样变性和染色质边缘化。一种扩增疱疹病毒科聚合酶基因保守区域的通用巢式PCR检测呈阳性。测序产物与一种γ疱疹病毒关系最为密切，该病毒与来自大西洋和地中海宽吻海豚（瓶鼻海豚）阴茎病变的核苷酸同一性为93%。这种相似性支持了物种间性传播的假说。
