| El impacto nocivo producido por Caligus rogercresseyi en los centros de cultivo de salmónidos en el sur de Chile ha ido en aumento, por lo que es necesario tener un mejor conocimiento de la especie para poder combatirla haciendo énfasis en la etapa infectante de ésta, el estadío copepodito. Este estudio aporta conocimientos biológicos y conductuales de éste estadío frente al estímulo de tres especies de hospederos; Salmo salar, especie de cultivo, y Eleginops maclovinus e Hypsoblennius sordidus, ambas especies nativas. Se realizaron tres experimentos, dos de ellos basados en los estímulos atractantes emanados del pez hospedero, controlados mediante la formación del filamento frontal de adhesión y respuestas conductuales frente a este estímulo mediante un... |

| The present paper summarizes the serotyping scheme of the fish pathogenic bacterium <i>Vibrio anguillarum</i> and defines seven additional O-serogroups. Strains, collected in our laboratories that were nontypable with antisera against the previously defined 16 O-serotypes, were used for generating new antisera and were characterized further by means of LPS profiles, Western blots, and serological reactions. On the basis of the results, it is suggested that the seven new O-serogroups are to be included in the existing serotyping system as serotypes O17-O<sub>2</sub>3. However, the existence of further <i>V. anguillarum</i> strains that were not typable with any of the 23 O-antisera suggested the existence of additional... |

| 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... |

| En febrero de 2003 en la Laguna de Yahuarcocha, se registró la muerte masiva de peces, estimándose que morían aproximadamente 500 peces/m2 por causas no conocidas. Fenómeno que se mantuvo durante algunas semanas disminuyendo paulatinamente el número de muertes. El Instituto Nacional de Pesca realizó un monitoreo durante los días 19 y 20 de marzo, con la finalidad de determinar las posibles causas, para lo cual se analizaron los parámetros ambientales, biológicos, identificación de las especies presentes en la laguna y la histopatología de los órganos y tejidos de los peces afectados. Los parámetros físico-químicos en la columna de agua y sedimentos registrados se encontraron dentro de los rangos normales para cuerpos lóticos. Desde el punto de vista... |

| Resumo: A cadeia do pescado na região da grande Dourados é considerada um polo produtivo de relevância na piscicultura nacional. Mesmo assim, sabe-se que sua organização, cooperativismo e assistência técnica, necessitam de apoio da pesquisa para que possam fomentar diversas demandas da atividade. Os resultados das pesquisas desenvolvidos pelo grupo de Sanidade Aquícola da Embrapa apontam a importância do monitoramento e controle das parasitoses na produção de peixes redondos. Os resultados apresentados neste documento foram uma compilação daqueles obtidos no projeto em rede Aquasec, projeto de prospecção de agentes etiológicos bacterianos, virais e parasitários de peixes redondos nas regiões nordeste, norte e centro oeste, atividades do NUPAQ-MS, além de... |

| A condition in Sparus aurata larvae termed "distended gut syndrome" (DGS) has become a major problem in the past three seasons. Unable to digest rotifers and brine shrimp nauplii, the larvae develop a swollen abdomen, exhibit a disoriented spinning motion and are swept passively with the current. Bacterial or viral infections were suspected. Chloramphenicol-supplemented larval food did not affect the prevalence of DGS. Virus-like particles 80 nm in diameter were observed in necrotic cytoplasm of midgut wall cells. |

| The spread of major diseases of molluscs around the world and the increase of transfers need the development of adapted prophylactic strategies and the increase of research in epidemiology, immunology and genetics. The prophylactic strategies must be based on common laws with the establishment of a list of declarable pathogens, with basic sampling rules (sample size, frequency, definition of geographical areas) and with reglementation of the internal transfers. Moreover, specific adapted diagnosis should be developed to increase the sanitary control performance (e.g. ELISA test, DNA probe, cell culture). In the case of an infectious disease the epidemiology studies should be concerned, the relationship between the culture techniques and the disease, the... |

| Mozambique tilapia Oreochromis mossambicus acclimated to 27 °C were then held at 19, 23, 27 (control), 31 and 35 °C, and were examined for non-specific cellular and humoral responses after 12–96 h. Total leucocyte count decreased significantly when fish were transferred to 19 and 23 °C after 48 and 96 h, and when transferred to 35 °C over 12–96 h, respectively. Respiratory burst decreased significantly when fish were transferred to 19, 31 and 35 °C over 24–96 h, whereas phagocytic activity and phagocytic index decreased significantly when fish were transferred to low temperatures (19 and 23 °C) and high temperatures (31 and 35 °C) over 12–96 h. Lysozyme activity decreased significantly when fish were transferred to 19 °C after 12–96 h, but increased... |
