Abstract: The present report is part of a larger study on the helminth fauna of Neotropical Cormorants, Phalacrocorax brasilianus (Gmelin, 1789) in Brazil, particularly, in the southernmost State of Rio Grande do Sul. The nematodes which were found loose in the proventriculus/ventriculus or in groups of adults of different ages and of L3 and L4 larval stages, forming eosinophylic granulomas had a prevalence of 100% in 47 Neotropical cormorants from Lago Guaíba, Municipality of Guaíba. The morphology of the labia/interla… Show more

“…Larvae of A. simplex damage the stomach of their intermediate and definite hosts (Smith & Wootten 1978, Young & Lowe 1969 and of the experimentally infested mammals. A similar ability to produce lesions in the stomach wall was observed during C. rudolphii invasions in cormorants (Huizinga 1971, Amato et al 2006). This study, too, found the black cormorant stomach to show numerous haemorrhages related to penetration of the mucosa by the larvae that subsequently undergo their last moult.…”

“…The nematode Contracaecum rudolphii is a cosmopolitan species, commonly found in ichthyophagous birds (Huizinga 1971, Kuiken et al 1999, Nottekämper et al 1999, Torres et al 2000, Abollo et al 2001, Torres et al 2005, Amato et al 2006. The nematode was first reported in Poland from the crested grebes (Podiceps cristatus, P. griseigena, P. ruficollis) in the Lublin Upland and in the little grebe (Tachybaptus ruficollis) near Białystok (Bezubik 1956).…”

“…Comments: Two adult male nematodes and 22 larval nematodes were isolated. The measures and morphological characteristics as number of pre-cloacal and post-cloacal papillae, spicules length, body length and other characteristics are coincident with Amato et al (2006), although the intestinal cecum and ventricular appendix are shorter. In the case of larvae, the morphological characteristics were coincident with the description of Kanarek & Bohdanowicz (2009).…”

“…The Contracaecum rudolphii Hartwich, 1964 nematode is a cosmopolitan parasite of piscivorous birds (Amato et al 2006, Kanarek 2011. As in most of the Anisakidae, its developmental cycle is complex and involves invertebrate animals and fish.…”
