spp. are zoonotic pathogens that can affect both terrestrial and marine mammals. has been identified in various cetacean species, but only one sequence type (ST27) has been reported in humans. However, it is important to conduct surveillance studies to better understand the impact of marine species on marine mammals, a typically understudied host group. Here, we describe a systemic infection by two related strains of (ST25) in a couple of live-stranded bottlenose dolphins, with more severe lesions in the younger animal. Furthermore, was first detected in milk from a female cetacean that stranded with its offspring. Our study reveals novel insights into the epidemiology and pathological consequences of infections in cetaceans, emphasizing the crucial importance of ongoing surveillance and accurate diagnosis to understand the impact of this pathogen on marine mammal populations.
种是能够感染陆地和海洋哺乳动物的人畜共患病病原体。已经在各种鲸目动物物种中被发现，但在人类中仅报告了一种序列类型（ST27）。然而，进行监测研究很重要，以便更好地了解海洋种对通常研究较少的海洋哺乳动物宿主群体的影响。在这里，我们描述了一对搁浅的宽吻海豚中由两种相关的（ST25）株引起的全身性感染，年轻的动物中出现了更严重的病变。此外，首次在与幼崽一起搁浅的雌性鲸目动物的乳汁中检测到。我们的研究揭示了鲸目动物中感染的流行病学和病理后果的新见解，强调了持续监测和准确诊断的至关重要性，以了解这种病原体对海洋哺乳动物种群的影响。
