Abstract

The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants\’ carcasses collected from 2001 to 2008 in Antofagasta, Biob\ío, and \Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. Ectoparasites collected were cleared and mounted for identification under a microscope. Fecal samples were also evaluated to determine the presence of protozoan parasites employing a flotation technique. A total of 44 (42.5\%) of birds were infested with at least one ectoparasite species, while 77 (96.25\%) were carrying endoparasites. No protozoan forms were found after examination. Most prevalent endoparasite species found were Contracaecum rudolphii s. l. (72/80, 90\%), followed by Pectinopygus gyroceras (33/80, 41.25\%), and Profilicollis altmani (26/80, 32.5\%). This is the first report of P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci, and Eidmaniella pelucida in the Neotropic cormorant. These findings also expand the distributional range of Andracantha phalacrocoracis, Paradilepis caballeroi, Hysteromorpha triloba, and P. gyroceras to Chile.

Resumo

O Bigu\á Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) \é amplamente distribu\ído na Am\érica Central e na do Sul. No Chile, as informa\ç\ões sobre parasitos para essa esp\écie s\ão limitadas a helmintos e nematoides, e pouco se sabe sobre outros grupos de parasitos. Este estudo documenta a fauna parasit\ária presente em 80 bigu\ás coletados de 2001 a 2008, nas regi\ões de Antofagasta, Biob\ío e \Ñuble. As aves foram inspecionadas externamente em busca de ectoparasitas; adicionalmente, foram realizadas necropsias para examinar os \órg\ãos digestivos e respirat\órios em busca de endoparasitos. Os ectoparasitos coletados foram limpos e montados para identifica\ç\ão ao microsc\ópio. As amostras de fezes tamb\ém foram avaliadas para determinar a presen\ça de parasitos protozo\ários, empregando-se uma t\écnica de flutua\ç\ão. Um total de 44 (42,5\%) aves estavam infectadas com pelo menos um ectoparasito, enquanto 77 (96,25\%) estavam portando endoparasito. Nenhuma forma de protozo\ário foi encontrada ap\ós o exame. As esp\écies de endoparasitos mais prevalentes encontradas foram Contracaecum rudolphii (72/80, 90\%), Pectinopygus gyroceras (33/80, 41.25\%) e Profilicollis altmani (26/80, 32.5\%). Este \é o primeiro registro de P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci e Eidmaniella pelucida no bigu\á. Esses resultados tamb\ém expandem a distribui\ç\ão de Andracantha phalacrocoracis, Paradilepis caballeroi, Ascocotyle felippei, Hysteromorpha triloba e P. gyroceras no Chile.
