| Introducción: las infecciones causadas por protozoos del género Leishmania constituyen un problema de salud mundial con una alta prevalencia en países subdesarrollados. En la actualidad no existe una vacuna contra esta enfermedad y el tratamiento utilizado es deficiente, por lo que la búsqueda de medicamentos más efectivos y seguros constituye una urgente necesidad. Objetivo: evaluar la actividad antileishmanial in vitro de 6 extractos acuosos e hidroalcohólicos de organismos marinos. Métodos: se determinó la actividad frente a promastigotes y amastigotes de Leishmania amazonensis, así como su toxicidad frente a macrófagos peritoneales de ratones BALB/c. Resultados: en el ensayo de promastigotes los extractos de Bryothamnion triquetrum, Bunodosoma... |

| Parasites nematodes as biological tags of Macruronus magellanicus (longtail hake) and Merluccius hubbsi (hake) colleted between 34°- 55°S in the SW Atlantic were studied. Adult specimens of Hysterothylacium aduncum, Ascarophis marina and Ichthytofilaria argentinensis, and the third-stage specimens of H. aduncum, Anisakis simplex and Contracaecum aduncum were described. Histological studies showed that I. argentinensis provokes tissue reactions in the swim bladder of M. hubbsi. A wide distributional range of species can be represented by many fish populations or fishing stocks. As these can overlap in space, the proper identification of stocks is necessary for fisheries management. The parasitologic method is one currently used to determine stocks.... |

| Se amplía la distribución biogeográfica de Platasterias latiradiata (Gray), hasta el Ecuador, considerada un fósil viviente, la que ha sido encontrada sólo en el Pacífico Litoral mexicano y centroamericano. En un mapa se da a conocer la nueva distribución, así como también un estudio comparativo de la morfología externa de una manera similar a los reportes y contribuciones de Caso, M, (1961, 1970, 1976). También se incluye una tabla con las medidas de algunas partes del cuerpo consideradas de importancia taxonómica y fotografías mostrando la predación de gasterópodos (Olivela semistriata) como uno de sus alimentos preferidos. |

| Se presentan los resultados obtenidos luego del estudio de un rizocéfalo encontrado parasitando un anomuro, colectado en las aguas de la península de Guanahacabibes, en la región suroccidental de Cuba. El parásito fue localizado en el costado del abdomen de su hospedero. Es la primera consignación de este tipo de relación ínter específica, en las aguas cubanas. |

| Four species of the family Octopodidae were reported to occur along the Argentine coast Octopus tehuelchus, Eledone massyae, Enteroctopus megalocyathus and Robsonella fontaniana. The first two are distributed from Brazil to south of Rawson and San Jorge Gulf, respectively, in warm-temperate waters. E.megalocyathus and R.fontaniana are of Subantarctic origin, the first ranging from San Matias Gulf to Magellan Strait, the Beagle Channel and Malvinas Islands; R.fontaniana is distributed from San Matias Gulf southwards, with records in North Patagonian and San Jorge Gulfs, Chile and Peru. A synopsis of information about taxonomical status, patterns of geographic distribution and biological aspects of these four coastal octopodids is given. |

| An update of the knowledge on the three most important ommastrephid species that inhabit the SW Atlantic: Illex argentinus, Martialia hyadesi and Ommastrephes bartramii, is presented. Up to the moment, only I.argentinus was intensively studied. Its distribution, population structure, reproduction, growth and paralarval development are analyzed, togheter with other aspects of its biology, such as feeding, predators and parasites. Also its utilization for human consmption is considered. Regarding M.hyadesi and O.bartrami, information on their distribution and biology is presented. |

| Parasitized and non-parasitized hake fillets obtained at fish processing plants were compared in order to assess the efects of Kudoa rosenbuschi myxosporidia on muscle of Merluccius hubbsi. The following studies were carried out: a)incidence and severity of parasitism; b)proteolytic and spoilage at a histologic level; c)pH and proximal composition in parasitized and non-parasitized fillets; and c)parasitism action on gelified products. Gel strength, elasticity and organoleptic level in gelified products were lower for parasitized samples. Recommendations are put forward as to conditioning and cooling of the catch and subsequent processing in order to lessen the effects of parasitism. |

| This study has been carried out over a period of four months (August, November 2001 and January, March 2002). The study aimed at establishing the magnitude of parasitization in different fish species as well as quantifying the relationship between the parasites and their fish hosts. Fish samples were collected from five main landing beaches: Vanga, Shimoni, Gazi, Mombasa and Kilifi. Fish samples examined for Parasites included: Siganus sutor, Plectorhynchus flavomaculatus, P. Sordidus, Lethrinus nebulosus, Sardinella gibosa, Scarus horrid, Sellar crumenophthalmus, Rastrelliger kanarguta, Parupeneus indicus, Mugil cephalus, Scombromorus commerson, Epinephelus macrospilas, Thunnus sp, Leptoscarus viagensis, L. sordidus and Hemiramphus far. Fish samples were... |

| The host specificity and population dynamics of <i>Anguillicola crassus</i> in a number of paratenic hosts were investigated. Various freshwater fish species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and examined for L<sub>3</sub>-larvae of <i>Anguillicola crassus</i>. Sixteen species were found to be infected: all the physoclist species examined (<i>Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus</i> and <i>Perca fluviatilis</i>) and those physostome species of which a sufficient number could be examined to detect the infection (<i>Gobio gobio, Leuciscus... |
