Abstract:

A total of 97 southern silvery grebes (Podiceps occipitalis), which died as the result of an oil spill on the coast of central Chile, were examined for ecto- and endoparasites. Two lice species including Aquanirmus rollandii (Philopteridae) and Pseudomenopon dolium (Menoponidae) were found from 6.2% (6/97) of birds. In 91.7% (89/97) of cases, grebes were infected with some kind of helminths. Three species of gastrointestinal helminths were detected: Eucoleus contortus (Nematoda), Profilicollis bullocki (Acanthocephala), and Confluaria sp. (Cestoda). In addition, Pelecitus fulicaeatrae (Nematoda) was removed from the tibiotarsal-tarsometatarsal articulation in 13.4% (13/97) of the specimens examined. To our knowledge, these are the first records of A. rollandii, E. contortus, and Confluaria sp. as parasites of P. occipitalis. In addition, these findings expand the distributional range of A. rollandii, E. contortus, P. fulicaeatrae, and Confluaria sp. to Chile.

Resumo

Um total de 97 mergulhões-de-orelha-amarela (Podiceps occipitalis), que morreram devido a um derramamento de óleo na costa do Chile central, foram examinados em busca de parasitos internos e externos. Parasitos externos foram encontrados em 6,2% (6/97) das aves, com a identificação de duas espécies de piolhos: Aquanirmus rollandii (Philopteridae) e Pseudomenopon dolium (Menoponidae). Em 91,7% (89/97) dos casos, os mergulhões apresentaram algum tipo de parasito interno. Foram detectadas três espécies de parasitos gastrointestinais: Eucoleus contortus (Nematoda), Profilicollis bullocki (Acanthocephala) e Confluaria sp. (Cestoda). Além disso, Pelecitus fulicaeatrae (Nematoda) foi isolado das articulação tibiotársica e tarsometatarsal em 13,4% (13/97) das aves examinados. Estes resultados correspondem ao primeiro relato de A. rollandii, E. contortus e Confluaria sp. associados com P. occipitalis, e expandem a distribuição destes parasitos e P. fulicaeatrae para o Chile.
