The aim of this study was to investigate the component community of parasite metazoans of Piaractus brachypomus in the lower Amazon River, northern Brazil. From 34 necropsied fish, 27,384 metazoan parasites were collected, such as Anacanthorus spathulatus, Mymarothecium viatorum and Notozothecium janauachensis (Monogenoidea); Spectatus spectatus and Contracaecum sp (Nematoda); Clinostomum marginatum and Dadaytrema oxycephala (Digenea); and Argulus carteri and Ergasilus sp. (Crustacea). The dominant species was S. spectatus followed by monogenoidean species, and there was aggregated dispersion of parasites, except for D. oxycephala and Contracaecum sp., which presented random dispersion. Positive correlation among the abundance of the three monogenoideans... |

Biological invasions are considered a major threat to biodiversity around the world, but the role of parasites in this process is still little investigated. Here, we compared parasite infections of a host species in the areas where it originated and where it was introduced, and in native and introduced species in the same environment, using the endoparasites of the fish Plagioscion squamosissimus (Sciaenidae) in 3 Brazilian basins. Samples were taken in 2 rivers where the species is native, i.e., Solimões River (SO) and Tocantins River (TO), and where the species was introduced, the upper Parana´ River (PR). In addition, abundances of diplostomids and larval nematodes were compared between P. squamosissimus and 2 native competitors in the PR, Hoplias... |

No Brasil, a produção pesqueira de Piaractus brachypomus (pirapitinga) vem apresentando pequeno aumento anual. Porém, essa produção extrativista é baixa se comparada à produção da aquicultura dessa espécie de peixes nativo da Amazônia. Piaractus brachypomus é um peixe bastante comercializado em mercados e feiras das capitais de estados da Amazônia brasileira. O objetivo deste estudo foi investigar a comunidade de parasitos metazoários em P. brachypomus do baixo Rio Amazonas, estado do Pará, Norte do Brasil. Métodos usuais de coleta, fixação, conservação e identificação dos parasitos foram usados neste estudo. Os termos ecológicos usados foram os recomendados na literatura. O índice de Brillouin (HB), uniformidade (E), índice de dominância de Berger-Parker... |

The purpose of this study was to use the informations relating to parasite crustaceans species that was published over the course of one century (1913 to 2013), in order to search for infestation and distribution patterns among these ectoparasites in Brazilian freshwater fish species. This search was carried out on 445 samples of 119 host fish of 27 families within the orders Characiformes, Perciformes, Clupeiformes, Mugiliformes, Osteoglossiformes, Symbranchiformes, Tetraodontiformes and Siluriformes from various regions of Brazil. We organized different host-parasite systems into matrices grouping species at different taxonomic and infestation levels and according to host parameters. Five families of parasites (Ergasilidae, Argulidae, Lernaeidae,... |

Apesar de sua conhecida resistência, os ovinos estão sujeitos as endoparasitoses, sendo este o principal fator limitante para a sua produção em todo o mundo, especialmente em regiões tropicais. Este trabalho objetiva avaliar a carga parasitária, o perfil hematológico e bioquímico sérico, e o grau Famacha de ovinos sem padrão racial definido infectados e tratados com ivermectina e closantel. O trabalho foi realizado no mês de julho de 2010, numa propriedade rural no município de Mossoró-RN. Foram selecionados 41 animais, os quais foram divididos em três grupos: grupo I- controle (sem tratamento), grupo II- tratado com ivermectina (0,2mg/kg) e Grupo III- tratado com closantel (5mg/kg). As amostras de fezes foram coletadas nos dias 0, 7, 14 e 21,... |

We analyzed the infestation levels of Excorallana berbicensis on Acestrorhynchus falcirostris, Ageneiosus ucayalensis, Geophagus proximus, Hemiodus unimaculatus, Psectrogaster falcata and Serrasalmus gibbus in a reservoir in the Araguari River basin, northern Brazil, during the dry and rainy seasons. For P. falcata, the infestation levels due to E. berbicensis were greater during the rainy season. For all the species studied, the peak parasite prevalence was in the month of highest rainfall levels and there were two peaks of parasite abundance: one in the month with highest rainfall level and the other in the month of transition from the rainy season to the dry season. In these hosts, around 70% of the E. berbicensis specimens were collected during the... |

This study describes the parasitic fauna of Mylossoma duriventre caught at Lake Coari, a tributary of the middle Solimões River, in the state of Amazonas (central Amazon, Brazil) and the relative condition factor (Kn). Out of 70 necropsied specimens, 90% had the gills parasitized by the helminth Anacanthorus paraspathulatus Kritsky, Boeger & Van Every, 1992 (Dactylogyridae: Anacanthorinae) and the intestine by Eustrongylides Jägerskiöld 1909 (Nematoda: Dioctophymatidae) larvae. A total of 19,763 specimens of A. paraspathulatus were collected, but the infection by Eustrongylides sp. larvae seemed to be accidental, after all, only three hosts were trophically infected. However, there was no significant difference (p<0.05) in the Kn of parasitized and... |

Specimens of Braga patagonica Schiödte & Meinert, 1884 (Isopoda: Cymothoidae) from freshwater fishes deposited in Ichthyological Collection of Amazon National Research Institute (INPA), in central Amazon and from fishes from eastern Amazon (Brazil) were investigated. Prevalence, infection intensity and body measures of B. patagonica for different populations of this cymothoid in wild fishes species from Amazon were carried out. Four species of Serrasalmidae, one Characidae, one Cichlidae, one Cynodontidae, one Curimatidae, one Acestrorhynchidae and one Sciaenidae were recorded as new hosts for B. patagonica in the Amazon. This study indicates a low intensity and low parasitic specificity of B. patagonica, and also recorded the first parasitism by this... |

This study provides the first investigation on acquisition of parasites in invasive O. niloticus by parasite species of native Cichlidae from the Igarapé Fortaleza basin, Northern Brazil. There were examined 576 specimens of 16 species of native cichlids and invasive O. niloticus collected in the main channel and the floodplain area of this tributary of Amazon River. The invasive O. niloticus was poorly parasitized having only Ichthyophthirius multifiliis, Trichodina centrostrigeata, Paratrichodina africana, Trichodina nobilis (Protozoa) and Cichlidogyrus tilapiae (Monogenoidea), and this host has not acquired any parasite species common to the native ichthyofauna region. In contrast, species of native cichlids showed rich fauna of parasites with... |

The aim of this study was to investigate the parasitic endohelminth fauna of Metynnis hypsauchen from Jari River basin, in Brazilian Amazon. The 30 examined fish were parasitized by one or more species of endoparasites. A total of 4337 parasites were collected including Dadayus pacuensis, Procamallanus (Spirocamallanus) inopinatus, Spinoxyuris oxydoras, Contracaecum sp. and Acanthocephala gen. sp. However, there was a dominance of D. pacuensis followed by S. oxydoras, and all parasites showed an aggregate dispersion. There was positive correlation between the abundance of P. (S.) inopinatus and the length and abundance of D. pacuensis with the weight of the host. The body condition of the hosts was not affected by parasitism. This first study on parasites... |

The present work morphologically characterizes Paratrichodina africana from the gills of wild and farmed Nile tilapia from Northern Brazil (eastern Amazonia). Ninety fish were captured for parasitological analysis in Macapá, State of Amapá, from a wetland area bathed by the Amazon River commonly called ?Ressaca do Zerão? (n = 52), as well as from a local fish farm (n = 38). Wet smears of the skin and gills of the captured fish were air dried at room temperature and impregnated with silver nitrate by Klein?s method for posterior examination of the adhesive disc structures. Total prevalence of parasitism was 16.6% (23% in fish from wetland and 7.8% in farmed fish). Characterized as a small‑sized trichodinid, it presented the following measures:... |
