In the period of October 2007 to August 2008, 152 specimens of Pygocentrus nattereri were caught in the Negro River in the Nhecolândia region, central Pantanal wetland, State of Mato Grosso do Sul, Brazil. The specimens were necropsied and a total of 4,212 metazoan endoparasites were recovered, belonging to 10 taxons: Procamallanus (Spirocamallanus) inopinatus, Philometridae gen. sp., Eustrongy...

Among 544 species of helminths recorded in birds on the territory of Poland, probably some (17 species of Digenea, 21 Cestoda, 13 Nematoda and 5 Acanthocephala) do not belong to the native fauna. These are helminths obtained in mature stage from birds shortly after their arrival from wintering grounds, or from foreign populations wintering with us, or being in the course of spring or autumn mig...

Abstract This checklist of parasites Kerodon rupestris, an endemic rodent from the Brazilian semiarid region, revealed records 25 enteroparasite taxa comprising Cestoda (Anoplocephalidae), Trematoda, Acanthocephala and Nematoda (Ancylostomidae, Ascarididae, Heterakidae, Oxyuridae, Pharyngodonidae, Trichuridae, Capillariidae, Trichostrongylidae, Strongyloididae), two coccidian. Paleoparasitologi...

Examination of bald eagles (Haliaeetus leucocephalus) collected from several locations in North America contributed new information concerning the acanthocephalan fauna of this host. Representatives of Arythmorhynchus brevis, representing a new host record, were collected from eagles in Florida, New Hampshire, and Wisconsin. Plagiorhynchus sp. was collected from an eagle in Florida. Corynosoma ...

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin I...

The aim of this paper was to test the hypothesis that when the 2 species of Acanthocephalan Pomphorhynchus laevis and Acanthocephalus clavula are found concurrently within the intestine of brown trout under field conditions, they have the potential to interact negatively. Evidence has shown that Acanthocephala are more likely to exhibit negative interactions with their own and other species, un...

A total of 107 leptodactylid frogs representing 6 species, Leptodactylus fuscus (n 5 15), Leptodactylus leptodactyloides (n 5 9), Leptodactylus mystaceus (n 5 2), Leptodactylus ocellatus (n 5 31), Leptodactylus petersii (n 5 31), and Leptodactylus pustulatus (n 5 19), collected in the Brazilian state of Tocantins, were examined for helminths. One species of Digenea (Catadiscus marinholutzi), 6 ...

Nine species of nematodes, unidentified larval nematodes, three species of trematodes, two species of acanthocephalans and a single species of chewing louse were collected from 1993 to 1995 from 25 introduced whooping cranes (Grus americana) in Florida (USA). In spite of a quarantine procedure involving anthelmintic therapy, three helminth parasites may have been introduced from captive populat...
