The current study presents a parasitological survey of larval nematodes from freshwater ornamental fish Iguanodectes spilurus caught in the watercourse of the Caete River, in the northeast region of the State of Para, Brazil. A total of 176 specimens, 1.36±0.75 g weight and 5.53±0.98 cm total length, were analyzed. Nematode larvae were identified as Capillaria sp., Procamallanus sp. and Anisakidae, with prevalence of 70.45% and infection intensity ranging from 1.81 to 4.70 larvae. The highest prevalence 57.38% occurred in the liver, but no seasonality was observed, indicating high infection throughout the year. Seasonality was observed in fish parasitized in the stomach, intestine and caecum, with prevalence and mean intensity of 17.61% and 2.32 parasites,... |

Achatina fulica or "giant African snail" is an exotic species, considered to be one of the world's hundred most invasive species, causing serious environmental damages. In the present study we report, for the first time, the occurrence of Aelurostrongylus abstrusus infecting A.fulica in the Amazon region. This nematode is described parasitizing mainly the pulmonary system of felines, which causes "aelurostrongilose", also known as feline cardio-pulmonary strongyloidosis. New morphometric data of third stage larvae are presented herein. The present study demonstrated that 40% of all the snails were infected by A. abstrusus. Achatina fulica specimens were collected from three different areas in Manaus namely: rural; east and west areas. The east area... |

RESUMO Devido à ampla distribuição da leishmaniose visceral (LV) no Brasil e à importância dos cães no ciclo de transmissão dessa zoonose, o presente estudo teve como objetivo avaliar a ocorrência de Leishmania spp. e caracterizar a espécie circulante em diferentes tecidos biológicos de cães da Baixada Cuiabana, Mato Grosso, Brasil. Amostras de sangue, linfonodo e medula óssea foram coletadas de 205 cães para realização de análise parasitológica por citologia e análise molecular por meio da nested PCR (nPCR) e do sequenciamento . Dos 205 cães estudados, 34 (16,58%) animais foram positivos pela nPCR, dos quais 12 possuíam formas amastigotas de Leishmania spp. na citologia. Amostras positivas na nPCR foram sequenciadas e caracterizadas como Leishmania... |

ABSTRACT: The aim of this study was to evaluate the histological changes in the liver of thirty-five Gymnotusspp. parasitized by endohelminths collected between April 2012 to October 2013 in commercial bait fish farming of Pantanal basin. Histological cuts of 7µm were stained with hematoxylin-eosin for parasites research and liver changes and have also been submitted to the Perls histochemical method for evaluation of hemosiderosis (Fe+++) based on the incidence degree and severity of change (Grade I, II and III) and tests for the presence of central melanomacrophages. Parasites identified were: Brevimulticaecumsp. with a prevalence of 22,9%, Eustrongylidessp 17,1%, Contracaecumtype I 68,7%, Contracaecumtype II 5,7%, Contracaecumtype III 5,7% and larvae of... |

ABSTRACT We described infracommunities, prevalence and mean intensity of infestation of ecotoparasite flies (Nycteribiidae and Streblidae) on bats in an ecotone area of Cerrado as predominant vegetation, with influence of Atlantic Forest, in the southeast of Mato Grosso do Sul. In 36 sampling nights between April 2015 and August 2016 (23,328 m².h), we captured 17 bat species, of which ten were infested, and 14 species of fly. The most abundant bats were the phyllostomids Artibeus planirostris (Spix, 1823), Glossophaga soricina (Pallas, 1776) and Carollia perspicillata (Linnaeus, 1758) and the most abundant flies were the streblids Trichobius longipes (Rudow, 1871), T. joblingi Wenzel, 1966 and Megistopoda aranea (Coquillett, 1899). Phyllostomus hastatus... |

Resumo: Este trabalho avaliou a eficacia de alguns anti-helminticos na reducao do OPG em caprinos e ovinos. Para iisto foram delineados tres experimentos. No experimento 1 foram testados os benzimidozois: fenbendazole (5,0 mg?kg), exfendazole (4,75 mg/kg), albendazole (3,8 mg/kg) e thiabendazole (44,0 mg/kg) em infeccoes naturais por nematodeos em caprinos. No experimento 2, foi feita uma infecai experimental com 4.000 larvas de Haemonchus contortus em caprinos e ovinos, e posteriormente testados o ivermectin (200 mcg/kg) e o netobimin (20 mg/kg). No experimento 3 avaliou-se o levamisole (7,5 mg/kg) em ovinos naturalmente infectados com nematodeos. A reducao do OPG nos caprinos medicados com benzimidazois foi de 84,3%, 92,8%, 73,2% e 30,0%, para o... |

Considering the epizootics which affect the French stock of flat oysters, Ostrea edulis (Grizel, 1985), trials to introduce an Australian oyster, Ostrea angasi, have been undertaken. The spat produced in a hatchery from breeders imported from Australia were reared in the south ofBrittany and in Normandy (Bougrier et al., 1986). Following mass mortalities (65% of individuals) a haplosporidian was observed in this species. Sporogenesis of the parasite was studied using Iight and electron microscopy. |

Because of diseases affecting fIat oyster Ostrea edulis, acclimatization of the Argentina oyster Ostrea puelchana has been tested in 1989-90 in five French oyster farming sites. Following ICES recommendations , hatchery produced juveniles, from parents imported from Argentina, were transferred to experimental si tes in summer 1989. Very high mortalities occurred, reaching 46 to 98% in March-Apri1 1990. They continued later on, resulting in the end of experiments in March 1991. The growth of surviving oysters was relatively poor in comparison of the local species. Parasites Marteilia refringens and Bonamia ostreae have been detected but at rates inadequate ta explain the high mortalities. AlI these results lead not to retain this species for breeding on... |

Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. After its first description in June 1979 in L'Ile Tudy, Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs. Bonamiosis and marteiliosis, another protozoan disease appeared in the seventies, drastically reduced the French flat oyster production from 20 000 tonnes in 1970 to less than 2000 tonnes after 1981. In 2001, about 1650 t of flat oysters were marketed in France. The production is restricted to several areas specialised in reproduction, growth and/or marketing, and depends on transfers of animals. Most important production... |

In 1983, the parasitism of Mytilus edulis L. by Proctoeces maculatus (Loose, 1901) Odhner, 1911 (Trematoda, Digenea, Fellodistomatidae), was recorded for the first time by the authors from mussels farming on stakes (Western Cotentin). After analysing the distribution of the prevalence on the shore and bibliographical data, it was suggested that this parasite must follow a biological cycle that had never been observed on the French coasts and that the most probable host of eggs producer - adult or progenetic metacercaria - would not be a fish but the Prosobranch Gasteropod Nucella lapillus . This was confirmed in 1987. This discovery enabled the authors to support a campaign of eradication of this mussels predatory mollusc. In 1990, the parasitism has... |

Bonamia ostreae, an intrahemocytic protozoan parasite infecting the oyster Ostrea edulis, is responsible for an endemic disease affecting all intensive breeding areas of European countries. Epidemiological studies showed variable prevalences, 43% in Galicia (Spain), from 6% to 32% in France and 45% in the most important area of Ireland. The impact of oyster transfers, handlings, high densities have been implicated in the disease development but environmental stressors could be more involved than zootechnical methods. The effect of water temperature, salinity and tidal exposure were particulary examined to assess stress induced changes and determine physiological, biochemical and immunological state indices of oyster populations, which will contribute to... |
