In this study, we investigated the presence of gastrointestinal helminths in 97 captive birds (Psittaciformes and Accipitriformes) necropsied between June and December 2011 in the state of Paraiba, Brazil. Forty-three birds were infected. Psittaciformes were infected by nematode Ascaridia hermaphrodita (97.6%) and cestode Raillietina sp. (2.4%). A. hermaphrodita was found in all species of parr...

A survey of gastrointestinal helminth communities of Gallotia caesaris caesaris (Lehrs, 1914) and G. c. gomerae (Boettger and MUller, 1914), from the islands of El Hierro and La Gomera, respectively, in the Canary Archipelago, Spain, was conducted to determine the prevalence, intensity, and diversity of intestinal parasites of these lacertid lizards. Larval forms of cestodes, nematodes, and aca...

The present work described helminth parasites of curimbatá, Prochilodus lineatus Valenciennes, 1836 from Volta Grande Reservoir, MG, Brazil. Eighteen fishes with average 46.7 +/- 1.1 cm length and 1,674.8 +/- 75.6 g weight were collected. Of the analysed fishes, 15 were parasitized with acanthocephalans in the intestine, showing a prevalence of 83.3%. The helminth was identified as Neoechinorhy...

Members of phylum Acanthocephala are parasites of vertebrates and arthropods and are distributed worldwide. The phylum has traditionally been divided into three classes, Archiacanthocephala, Palaeacanthocephala, and Eoacanthocephala; a fourth class, Polyacanthocephala, has been recently proposed. However, erection of this new class, based on morphological characters, has been controversial. We ...

Parasitic helminths with complex life cycles require multiple hosts in a particular order to complete their cycles. Although almost all infect invertebrates at some point cycle, we know very little about which species of harbor parasites compared what is known for vertebrates. In New Zealand, <1% marine that may be expected host have records parasite infections. This strong indication our knowl...

Hyporthodus niveatus is an appreciated and valuable commercial fish species in the municipality of Niterói, state Rio de Janeiro, Brazil, due its excellent quality flesh. The constant presence helminths abdominal musculature, viscera serosa individuals has been subject complaints among local traders because economic losses to their repugnant aspect. Considering hygienic-sanitary importance sign...

Five species of adult nematodes, unidentifiable nematode larvae, and three species of acanthocephalans, were found in freshwater ornamental fishes newly imported into Germany from Brazil, Colombia, Indonesia, Malaysia, Nigeria, Peru, Sri Lanka and Thailand. The following species were identified: Adult Nematoda: Pseudocapillaria tomentosa, Capillariidae gen. sp., Dichelyne hartwichi sp. n., Proc...
