Seven species of helminths and six species of arthropods are reported from 23 of 40 brown pelicans, Pelecanus occidentalis, collected from various localities in Puerto Rico. Helminth parasites include three nematodes (Contracaecum multipapillatum, Contracaecum mexicanum, and Eustrongylides sp.), three trematodes (Galactosomum darbyi, Mesostephanus appendiculatoides, and Ribeiroia ondatrae), and one cestode (Tetrabothrium sulae). Arthropod parasites include Colpocephalum occidentalis, Neottialges apunctatus, Ornithodoros capensis, Phalacrodectus pelecani, Phalacrodectus punctatissimus, and Phalacrodectus sp. The presence of R. ondatrae in the brown pelican is a new species host record, and P. pelecani, P. punctatissimus and N. apunctatus are new subspecies host records. C. multipapillatum, C. mexicanum, G. darbyi and M. appendiculatoides are new locality records for Puerto Rico, and N. apunctatus, P. pelecani, P. punctatissimus and T. sulae are new locality records for the Caribbean. Necrosis produced by C. multipapillatum, C. mexicanum, and R. ondatrae may have contributed to the emaciation and death of the brown pelicans examined in the present study.
在从波多黎各各地收集的40只褐鹈鹕（Pelecanus occidentalis）中，有23只检测出7种蠕虫和6种节肢动物。蠕虫寄生虫包括三种线虫（多乳头对盲囊线虫、墨西哥对盲囊线虫和艾氏并殖吸虫）、三种吸虫（达氏半尾吸虫、附肢中殖吸虫和奥氏 Ribeiroia）和一种绦虫（苏氏四叶绦虫）。节肢动物寄生虫包括西方头蜱、无斑新蚤、卡氏钝缘蜱、鹈鹕甲螨、多斑甲螨和甲螨属物种。奥氏 Ribeiroia 在褐鹈鹕体内的发现是一个新的宿主记录物种，而鹈鹕甲螨、多斑甲螨和无斑新蚤是新的亚种宿主记录。多乳头对盲囊线虫、墨西哥对盲囊线虫、达氏半尾吸虫和附肢中殖吸虫是波多黎各的新地点记录，无斑新蚤、鹈鹕甲螨、多斑甲螨和苏氏四叶绦虫是加勒比地区的新地点记录。多乳头对盲囊线虫、墨西哥对盲囊线虫和奥氏 Ribeiroia 造成的坏死可能是本研究中检查的褐鹈鹕消瘦和死亡的原因。
