The tissues and parasites collected from Peruvian fur seals (Arctocephalus australis) and South American sea lions (Otaria byronia) found dead at Punta San Juan, Peru were examined. The respiratory mite, Orthohalarachne attenuata infected 3 out of 32 examined fur seals and 3 out of 8 examined sea lions, however caused moderate to severe lymphohistiocytic pharyngitis only in fur seals. Hookworms, Uncinaria sp, infected 6 of the 32 examined fur seals causing variable degrees of hemorrhagic and eosinophilic enteritis. This parasite caused the death of 2 of these pups. In fur seals and sea lions, Corynosoma australe and Contracaecum osculatum were not associated with significant tissue alterations in the intestine and stomach respectively. Respiratory mites and hookworms have the potential to cause disease and mortality among fur seals, while parasitic infections do not impact significatively the health of sea lions at Punta San Juan, Peru.
对在秘鲁圣胡安角发现死亡的秘鲁毛皮海狮（南极海狗）和南美海狮（拜伦海狮）采集的组织和寄生虫进行了检查。呼吸道螨类，即细弱正海螨，在32只接受检查的毛皮海狮中有3只被感染，在8只接受检查的海狮中有3只被感染，但仅在毛皮海狮中引起了中度至重度淋巴细胞性咽炎。钩虫，即狭头钩虫，在32只接受检查的毛皮海狮中有6只被感染，导致不同程度的出血性和嗜酸性肠炎。这种寄生虫导致其中2只幼崽死亡。在毛皮海狮和海狮中，南方冠海豹属和吻状对盲囊线虫分别在肠道和胃中未引起明显的组织改变。呼吸道螨类和钩虫有可能在毛皮海狮中导致疾病和死亡，而在秘鲁圣胡安角，寄生虫感染对海狮的健康没有显著影响。
