Information regarding parasitic fauna of cetaceans from Costa Rica is provided for the first time. A total of 25 stranded dolphins and whales were examined between 2001 and 2009, including striped dolphin (Stenella coeruleoalba) (n=19), pantropical spotted dolphin (S. attenuata) (n=2), spinner dolphin (S. longirostris) (n=1), bottlenose dolphin (Tursiops truncatus) (n=1), dwarf sperm whale (Kogia sima) (n=1) and Cuvier's beaked whale (Ziphius cavirostris) (n=1). Pathological findings associated with the parasites are also presented. In the most representative dolphin species, S. coeruleoalba, the prevalence of parasites was 89.5%; moreover, all examined specimens of S. attenuata, S. longirostris, T. truncatus and Z. cavirostris presented parasites. No parasites were recovered from K. sima. Fourteen helminth taxa were identified, including six species of cestodes (Strobilocephalus triangularis, Tetrabothrius forsteri, Trigonocotyle sp., Phyllobothrium delphini, Monorygma grimaldi, Tetraphyllidea gen. sp. plerocercoid), four digeneans (Nasitrema globicephalae, Brachycladium palliatum, B. pacificum and Oschmarinella albamarina) and four nematodes (Anisakis spp., Halocercus lagenorhynchi, Halocercus sp. and Crassicauda anthonyi). A commensal crustacean, Xenobalanus globicipitis, was also identified. All identified parasites representing new geographic records for the Pacific coast of Central America and new host records are presented. Parasitological information is valuable for conservation of cetaceans in Pacific coast of Costa Rica.
首次提供了哥斯达黎加海洋哺乳动物寄生虫群的信息。在 2001 年至 2009 年期间，共检查了 25 头搁浅的海豚和鲸鱼，包括条纹海豚（Stenella coeruleoalba）（n=19）、斑点海豚（S. attenuata）（n=2）、飞旋海豚（S. longirostris）（n=1）、宽吻海豚（Tursiops truncatus）（n=1）、小抹香鲸（Kogia sima）（n=1）和白腰斑纹海豚（Ziphius cavirostris）（n=1）。还介绍了与寄生虫相关的病理学发现。在最具代表性的海豚物种条纹海豚中，寄生虫的流行率为 89.5%；此外，所有检查的斑点海豚、飞旋海豚、宽吻海豚和白腰斑纹海豚的标本都有寄生虫。小抹香鲸未发现寄生虫。共鉴定出 14 种寄生虫，包括 6 种绦虫（Strobilocephalus triangularis、Tetrabothrius forsteri、Trigonocotyle sp.、Phyllobothrium delphini、Monorygma grimaldi、Tetraphyllidea gen. sp. plerocercoid）、4 种复殖吸虫（Nasitrema globicephalae、Brachycladium palliatum、B. pacificum 和 Oschmarinella albamarina）和 4 种线虫（Anisakis spp.、Halocercus lagenorhynchi、Halocercus sp. 和 Crassicauda anthonyi）。还鉴定了一种共生甲壳类动物 Xenobalanus globicipitis。所有鉴定的寄生虫均代表中美洲太平洋海岸的新地理记录和新宿主记录。寄生虫学信息对于保护哥斯达黎加太平洋海岸的海洋哺乳动物具有重要意义。
