Abstract: a benthic community constituted by an assemblage of at least four species of deep-sea corals collected in only one trawl carried-out on the summit of the o'higgins i seamount, central chile. the corals were collected in only one trawl carried-out during a chilean-japanese cruise onboard the r/v" koyo maru" in december 29, 2004. presence of oxygenated and cold antarctic intermediate water (>400 m depth) on the plateau was recorded under of the equatorial subsurface water associated to the oxygen-minimum zone (omz, <1 ml o2 l-1). the biogeographic origin of the fauna evidenced a mix of subantarctic and central chile continental margin species. the assemblage is represented by two species of anthipatarians (leiopathes sp. and chrysopathes sp.), one unidentified species of paragorgiidae and one species of isididae (acanella chilensis). the study demonstrated that deep-water corals of the o'higgins seamount provide crucial habitat for commercially important crustacean exploited along continental margin off central chile such as nylon shrimp (heterocarpus reedi). this resource as well as some fishes such as alfonsino (beryx splendens) and orange roughy (hoplostethus atlanticus) could drawing the commercial fishing industry to these fragile areas poorly known chilean marine benthic communities. due to a strong economic pressure, fast actions for marine conservation of seamounts are required in chile.

Abstract: A benthic community constituted by an assemblage of at least four species of deep-sea corals collected in only one trawl carried-out on the summit of the O'Higgins I seamount, central Chile. The corals were collected in only one trawl carried-out during a Chilean-Japanese cruise onboard the R/V" Koyo Maru" in December 29, 2004. Presence of oxygenated and cold Antarctic Intermediate Water (>400 m depth) on the plateau was recorded under of the Equatorial Subsurface Water associated to the oxygen-minimum zone (OMZ, <1 mL O2 L-1). The biogeographic origin of the fauna evidenced a mix of Subantarctic and central Chile continental margin species. The assemblage is represented by two species of anthipatarians (Leiopathes sp. and Chrysopathes sp.), one unidentified species of Paragorgiidae and one species of Isididae (Acanella chilensis). The study demonstrated that deep-water corals of the O'Higgins seamount provide crucial habitat for commercially important crustacean exploited along continental margin off central Chile such as nylon shrimp (Heterocarpus reedi). This resource as well as some fishes such as alfonsino (Beryx splendens) and orange roughy (Hoplostethus atlanticus) could drawing the commercial fishing industry to these fragile areas poorly known Chilean marine benthic communities. Due to a strong economic pressure, fast actions for marine conservation of seamounts are required in Chile. Se describe una comunidad bentónica constituida por un ensamble de cuatro especies de corales de profundidad recolectados mediante un lance de arrastre efectuado sobre el margen de la meseta del monte submarino O'Higgins I, Chile central. Sobre la meseta se detectó la presencia de agua oxigenadas frías correspondientes al Agua Intermedia Antártica (>400 m de profundidad) y sobre ésta, el Agua Ecuatorial Subsuperficial asociada a la zona de mínimo de oxígeno (OMZ, <1 mL O2 L-1). La fauna muestra un origen biogeográfico de tipo subantártico sumado a la presencia de fauna típica del margen continental de la zona central de Chile. Este ensamble está representado por dos especies de Antipataria (Leiopathes sp. y Chrysopathes sp.), una especie no identificada de la familia Paragorgiidae y una especie perteneciente a la familia Isididae (Acanella chilensis). Este estudio muestra que este ensamble de corales de profundidad provee un hábitat crítico para el camarón nailon (Heterocarpus reedi), crustáceo de importancia pesquera. La presencia de este crustáceo más algunos peces como el alfonsino (Beryx splendens) y orange roughy (Hoplostethus atlanticus) podrían atraer la at

Abstract: introduction: fascioliasis is an endemic disease in cattle in cuba, but in the last few years, there has been an increase in the number of reported human cases. objectives: the difficulties in diagnosing this disease in rural areas or in zones far away from the laboratory make it necessary to find adequate solutions that allow preserving the stool specimens until the antigen is detected by the fascidig? method. methods: several preserving solutions were used (2 % potassium dichromate, 0,5 % aqueous hibitane, 2 % glutaral, 1 % benzalkonium chloride, 0,04% sodic azide and 0,05 % distilled water with 20 tween) at room temperature, 4 oc and - 20 oc. results: among the samples kept at room temperature, those with no preserve suffered a significant deterioration, and their values were higher than the ones of the samples conserved with distilled water with tween 20 and with sodium azide. the latter is a very toxic product and its use would require a greater care. conclusions: 0,05 % distilled water with 20 tween at room temperature was the preserving solution with the best results in this study.

Abstract: INTRODUCCIóN: la fasciolosis en Cuba es una enfermedad endémica en el ganado y en los últimos a os ha tenido un incremento en el número de casos reportados en humanos. OBJETIVOS: por causa de las dificultades para realizar el diagnóstico de esta enfermedad en zonas rurales o alejadas del laboratorio se ha hecho necesario buscar soluciones preservantes, que permitan conservar las muestras de heces hasta el momento de la determinación de antígeno por el método de FasciDIG . MéTODOS: se utilizaron diferentes soluciones preservantes (dicromato de potasio 2 %, hibitane acuoso 0,5 %, glutaral 2 %, cloruro de benzalconio 1 %, azida sódica 0,04 % y agua destilada con tween 20 0,05 %) a temperatura ambiente, 4 oC y - 20 oC. RESULTADOS: en las muestras preservadas a temperatura ambiente, las que no tenían preservo sufrieron un gran deterioro, mostraron valores superiores a las conservadas con agua tween 20 y con azida sódica. Esta última es un producto altamente tóxico, por ser un inhibidor de la cadena respiratoria y requeriría de un mayor cuidado en su utilización. CONCLUSIONES: se sugiere que la solución preservante de agua destilada con tween 20 0,05 % a temperatura ambiente mostró los mejores resultados en el estudio.

Abstract: the fascioliasis is a parasitic infection caused by tremadotes of fasciola genre and the more frequent species is fasciola hepatica which is distributed in all continents and to infecting many mammals, including the man. to complete its life cycle, this trematode needs an intermediate host, represented by a mollusk from lymnaeidae family. in cuba two species are known: fossaria cubensis and pseudosuccinea columella. the clinical manifestations are not specific and varied according to the disease phase, acute, latent or chronic. the certainty diagnosis of the human fascioliasis is based in the finding that the parasite eggs present in feces or in duodenal fluid of parasitized individual. other immuno-enzymatic methods have been developed allowing a great approaching to diagnosis of this entity. the epidemiological situation of this parasitosis has change in past years. from 1980 the figure of notifications of infected persons has significantly increase in some zones. in cuba it behaves as an enzootic disease of bovine cattle and account for many loss in livestock and food industries allowing to consider it as a zoonotic disease a great economic significance and of great medical-veterinary interest. yearly human cases are diagnosed like outbreaks or sporadic cases, thus each day the need of attention to prevention and diagnosis of this parasitosis is reinforced.
Fascioliasis, revisión clínico-epidemiológica y diagnóstico Fascioliasis, clinical-epidemiological review and diagnosis

Revista Cubana de Higiene y Epidemiología , 2012,
Abstract: La fascioliasis es una infección parasitaria causada por trematodos del género Fasciola, y la especie más frecuente es Fasciola hepatica, la cual se encuentra distribuida en todos los continentes e infecta a gran cantidad de mamíferos, incluyendo al hombre. Este trematodo requiere, para completar su ciclo de vida, de un hospedero intermediario, representado por un molusco que pertenece a la familia Lymnaeidae. En Cuba se conocen dos especies: Fossaria cubensis y Pseudosuccinea columella. Las manifestaciones clínicas son inespecíficas y varían de acuerdo con la fase de la enfermedad, aguda, latente o crónica. El diagnóstico de certeza de la fascioliasis humana se basa en el hallazgo de los huevos del parásito en las heces o en el fluido duodenal del individuo parasitado. Pero se han desarrollado otros métodos inmunoenzimáticos que han permitido un mayor acercamiento al diagnóstico de esta entidad. La situación epidemiológica de esta parasitosis ha cambiado en los últimos a os. Desde 1980 el número de notificaciones de personas infectadas ha aumentado considerablemente en varias zonas. En Cuba se comporta como una enfermedad enzoótica del ganado bovino y es responsable de importantes pérdidas en las industrias pecuarias y alimenticias lo que nos permite considerarla como la enfermedad zoonótica de mayor importancia económica y de gran interés médico veterinario. Anualmente se diagnostican casos humanos en forma de brotes o casos esporádicos, por lo que cada día más se refuerza la necesidad de que se le brinde atención a la prevención y diagnóstico de esta parasitosis.

Abstract: abstract. this paper confirm the presence of the spionid polychaete prionospio (prionospio) orensanzi blake 1983, from a shallow, sandy, subtidal benthic area, between 5 and 20 m of depth, near to domestic wastewater and the las minas river fresh water discharge, off punta arenas (53°08'00"s, 70o51'15"w to 53°10'30"s, 70o54'30"w), chile. the external morphology of this specimens agree well with the original description of this species. p. (p.) orensanzi was collected together to 42 others polychaete species, where nine spionids species are listed. the family spionidae was the most common of the polychaetes collected in the sampling area, with p.(p.) orensanzi being the most abundant species. this new record confirm the presence of this species in chilean waters, increase to three the number of members of the genus prionospio (prionospio) on the chilean coast, and nearly to 41 the total number of species of spionidae from chile. a key to the chilean species of prionospio is presented

Abstract: an environmental monitoring index based on the temporal variations in the abundance of two benthic polychaetes (nepthys impressa baird, 1871 and prionospio peruana hartmann-schr?der 1962a) is proposed. three replicated samples were collected in four subtidal stations at quintero bay (32o45' s, 71o29' w; 6 to 13 m deep), central chile, with a van veen grab 0,1 m-2; the sampling campaigns were carried out in march and november 1995 and 1996, april, august and november 1997 and march 1998. this study allowed to evaluate the use of population parameters of the benthic component in environmental impact programs according to the technical requirements of dgtm and mm (chilean navy). nepthys impressa (ni) is a common species whose abundance (n) varied in one order of magnitude and occurred in sediments with low percentage of organic matter, mo (< 1%). instead, prionospio peruana (pp) is an opportunistic species, uncommon, with its abundance varying four orders of magnitude. this species was associated to altered sediments, moderately enriched in terms of organic matter (? 3%). the temporal variations in the abundance of both species allows to propose the environmental monitoring index (iva): iva = log [(nni/(npp + 1))* 100], the index identified three phases at subtidal sediments: a) a moderate enrichment in march, 1996 (3% mo; iva<1) with important population development of p. peruana, b) a recuperation of habitual conditions (< 1% mo; iva ? 3) in seven months retourning to the dominance of n. impressa, and c) after march 1996 iva showed lower values than those obtained before the event of enrichment (iva > 3). the use of this index in other chilean bays is discussed. other eighteen species of benthic polychaetes were collected in the shallow sandy bottom in the study area.
