infection has been reported in numerous species of marine mammals, some of them with fatal consequences. A serosurvey for infection was conducted in pinnipeds from an oceanographic park in Portugal ( = 60); stranded pinnipeds on the Portuguese coast ( = 10); and pinnipeds captured in Lorenzensplate, Germany ( = 99). Sera from 169 pinnipeds were tested for the presence of antibodies to by the modified agglutination test with a cut-off titre of 25. An overall seroprevalence of 8.9% (95% confidence interval: 5.1-14.2) was observed. Antibody titres of 25, 50, 100, 1600 and ≥3200 were found in five (33.3%), two (13.3%), five (33.3%), one (6.7%) and two (13.3%) animals, respectively. Pinnipeds under human care had a seroprevalence of 20.0% (12/60), in contrast to 2.8% (3/109) in wild pinnipeds ( < 0.001). General results suggest a low exposure of wild pinnipeds to , while the seroprevalence found in pinnipeds under human care highlights the importance of carrying out further studies. This is the first serological survey of in pinnipeds in Portugal and the first infection report in South African fur seal ().
已在众多海洋哺乳动物物种中报告了感染情况，其中一些会导致致命后果。对来自葡萄牙一个海洋公园的鳍足类动物（n = 60）、葡萄牙海岸搁浅的鳍足类动物（n = 10）以及在德国洛伦岑斯普拉特捕获的鳍足类动物（n = 99）进行了感染血清学调查。通过改良凝集试验对169只鳍足类动物的血清进行检测，以检测是否存在针对[病原体名称未给出]的抗体，截断滴度为25。观察到总体血清阳性率为8.9%（95%置信区间：5.1 - 14.2）。在五只（33.3%）、两只（13.3%）、五只（33.3%）、一只（6.7%）和两只（13.3%）动物中分别发现了滴度为25、50、100、1600和≥3200的抗体。人工饲养的鳍足类动物血清阳性率为20.0%（12/60），而野生鳍足类动物为2.8%（3/109）（P < 0.001）。总体结果表明野生鳍足类动物对[病原体名称未给出]的接触较少，而人工饲养的鳍足类动物中发现的血清阳性率凸显了开展进一步研究的重要性。这是葡萄牙首次对鳍足类动物进行[病原体名称未给出]血清学调查，也是南非海狗（[物种名称未给出]）首次感染报告。
