Disseminated toxoplasmosis has been described in northern fur seals, however little is known about the significance and epidemiology of this pathogen in free ranging populations. We tested archived serum from a subset of domestic cats () and adult northern fur seals (; NFS in the Pribilof Islands, Alaska, for antibodies and feline fecal samples for oocysts. Of the 37 cats, two (5.4 %) were seropositive and all (n = 36) fecal float samples were negative. Of the 225 NFS serum samples, 37 (16.4 %) were positive by modified agglutination tests. There was no statistically significant difference in the seroprevalence of NFS by year or region of animal capture. These findings suggest that exposure in both cats and NFS is present but appears lower in this region compared to other studied areas.
在北海狗身上已发现有播散性弓形虫病，但对于这种病原体在野生种群中的重要性和流行病学情况知之甚少。我们检测了一部分家猫（）和成年北海狗（；阿拉斯加普里比洛夫群岛的北海狗）的存档血清中的抗体，并检测了猫的粪便样本中的卵囊。在37只猫中，有两只（5.4%）血清呈阳性，所有（n = 36）粪便漂浮样本均为阴性。在225份北海狗血清样本中，有37份（16.4%）经改良凝集试验呈阳性。北海狗的血清阳性率在捕获动物的年份或地区上没有统计学上的显著差异。这些发现表明，猫和北海狗都存在接触弓形虫的情况，但与其他研究地区相比，该地区的接触率似乎较低。
