| A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical... |

| ABSTRACT Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these diseases is necessary. Natural products have stood out as an alternative to searching for new bioactive molecules with therapeutic potential. In this study, the chemical composition and antiparasitic activity of the essential oil from Protium ovatum leaves against trypomastigote forms of Trypanosoma cruzi and the promastigote forms of Leishmania amazonensis were evaluated. The essential oil was promising... |

| Arnoglossus laterna is only infested by intestinal parasites. Each parasite distribution is independent of the distribution of other parasites and also independent of the sex of host. When a fish is infested by a great number of the two helminths Acanthocephaloides and Bothriocephalus clavibothrium , the proportion of lymphocytes tends to decrease and the proportion of neutrophils tends to increase (inflammatory response). Important infestation by Scolex pleuronectis induces an increase of the thrombocyte count for 100 counted leucocytes. After infestation by the nematode Thynnascaris sp. alone or with another parasite, even by small number, the proportion of lymphocytes decreases and the proportion of neutrophils increases. |

| Un échantillonnage de poissons parasités (Diplodus puntazzo) en provenance d’une firme aquacole située au Sud-est de la Corse (Ouest méditerranéen) montre une infestation due à un Myxidium leei. Le parasite envahit l’épithélium intestinal causant amaigrissement du poisson et une forte mortalité. Les spécimens de plus de 16 cm de longueur totale étaient significativement moins infestés. Toutefois, l’infestation ne montre pas de différence significative entre mâles et femelles quelle que soit la taille des spécimens. Quelques paramètres hématologiques ont été utilisés pour montrer le rôle du parasite dans cette maladie de poissons et statuer sur l’interaction hôte-parasite. |

| Recientes problemas provocados por epiemias de infecciones de Ichthyophthirius multifiliie en la cría de bagre negro (Rhandia sapo) cultivado por el Departamento de Acuicultura del INAPE de Uruguay, y el conocimiento de que todos los piscicultores tienen problemas con los parásitos, constituyeron la base y antecedente para el inicio de un programa de investigaciones parasitológicas. Este programa incluyó. 1) Disección de bagres capturados en Laguna de Sauce y colecta de parásitos. 2) Disección de bagres cultivados en el Laboratorio y en los estanques de INAPE, y colecta de parásitos. 3) Identificación de los parásitos recolectados. 4) Elaboración de un manual que recopila los métodos más comunmente utilizados en parasitología e histopatología en la... |

| ABSTRACT Gastrointestinal parasitism is the main health problem faced by Spheniscus magellanicus, known as Magellanic penguins, in route on the Brazilian coast. The aim of this research was to report the occurrence and intensity of gastrointestinal parasites in S. magellanicus that reached Pontal do Sul, Paraná, South of Brazil. The study was performed at the Marine Study Center of the Federal University of Parana (CEM-UFPR) with 38 specimens, 31 were necropsied and seven were examined alive with coproparasitological exams. From the necropsied animals, 93.5% (29/31) were parasitized with at least one parasite species. Contracaecum pelagicum was the most prevalent 93,5% (29/31) parasite, followed by Cardiocephaloides physalis (64.5%) and Tetrabothrius lutzi... |

| 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... |
