    Salmonella enterica causes health problem worldwide. The relationships among strains that are from the same serotype but different hosts, countries, and continents remain elusive. Few genome sequences are available from S. enterica isolates from South America. Therefore, we sequenced the genomes of 33 strains from diverse sources isolated in Chile and determined that they were of different serotypes. These genomes will improve phylogenetic analysis of Salmonella strains from Chile and the res...

    Full Text Available La producción, importación y consumo de vinos experimentaron cambios significativos en el período que va entre la Independencia y la víspera de la Primera Guerra Mundial. En este trabajo se estudia la introducción de nuevas cepas y los cambios en las técnicas de vinificación desde mediados del siglo XIX. El desglose de las cifras de producción anual por provincia permite apreciar la difusión de las nuevas cepas, mientras que testimonios contemporáneos advierten sobre las diferencias en las calidades del producto. Las cifras de importación para los distintos tipos y envases de vinos reflejan estos cambios. La internación de tintos a granel experimenta una caída sistemática desde la década del 1870, no así el champaña que aún no se fabricaba en Chile. Más significativa es la creciente figuración de los vinos nacionales en los menús de los banquetes oficiales y sociales en el períodoThe production, imports and consumption of wine underwent significant changes in the years between Independence and the eve of the First World War. This article studies the introduction into Chile of new varieties of vines, and changes in winemaking techniques from the middle of the 19th century onwards. Annual production figures from the different provinces show the gradual penetration of the new varieties, and contemporary sources attest to the differences in the quality of the wines. Import figures for the different types of wine reflect these changes. Imports of plain red wines, though not for champagnes, show a steady decline from the 1870s. More tellingly, Chilean wines were increasingly served in official and social banquets during this period as indicated in the corresponding menus

La evidencia disponible muestra que a medida que aumentaron las facilidades de transporte, la producción y consumo aumentó desde los comienzos del siglo XX.This article provides a survey of fish and seafood supply and consumption in Chile. Reference is made to local species available in our coasts and the existing confusion between them. The difficulties in providing markets with fresh products, the early attempts to preserve fish and seafood and to establish fish farming, the volume of imports and estimates of local production, as well as the modes of preparation and consumer preferences, are considered in this study too. The available evidence shows that as transport facilities improved, production and consumption increased from the beginning of the Twentieth century.

Infant mortality is 18/1000. 34% of the population are involved in industry and commerce, 30% in services, 19% in agriculture and forestry and fishing, 7% in construction, and 2% in mining. The major city is Santiago. The government, which gained independence in 1810, is a republic with executive, legislative, and judicial branches. There are 12 regions. There are 6 major political parties. Suffrage is universal at 18 years. Gross domestic product (GDP) is $29.2 billion. The annual growth rate is 5% and inflation is 19%. Copper, timber, fish, iron ore, nitrates, precious metals, and molybdenum are its natural resources. Agricultural products are 9% of GDP and include wheat, potatoes, corn, sugar beets, onions, beans, fruits, and livestock. Industry is 21% of GDP and includes mineral refining, metal manufacturing, food and fish processing, paper and wood products, and finished textiles. $8.3 billion is the value of exports and $7 billion of imports. Export markets are in Japan, the US, Germany, Brazil, and the United Kingdom.

    Chile is a long (2650 miles), narrow (250 miles at widest point) country sandwiched between the Andes mountains and the Pacific. The northern desert is rich in copper and nitrates; the temperate middle region is agricultural and supports the major cities, including Santiago, the capital, and the port of Valparaiso; and the southern region is a cold and damp area of forests, grasslands, lakes, and fjords. The country is divided into 12 administrative regions. Chile's population of 12.5 million are mainly of Spanish or Indian descent or mestizos. Literacy is 92.3%, and the national language is Spanish. Infant mortality is 18.1/1000, and life expectancy is 68.2 years. 82% of the people are urban, and most are Roman Catholics. Chile was settled by the Spanish in 1541 and attached to the Viceroyalty of Peru. Independence was won in 1818 under the leadership of Bernardo O'Higgins. In the 1880s Chile extended its sovereignty over the Strait of Magellan in the south and areas of southern Peru and Bolivia in the north. An officially parliamentary government, elected by universal suffrage, drifted into oligarchy and finally into a military dictatorship under Carlos Ibanez in 1924. Constitutional government was restored in 1932. The Christian Democratic government of Eduardo Frei (1964-70) inaugurated major reforms, including land redistribution, education, and far-reaching social and economic policies. A Marxist government under Salvador Allende lasted from 1970 to 1973 when the present military government of General Pinochet Ugarte took power, overthrew Allende, abolished the Congress, and banned political parties. It has moved the country in the direction of a free market economy but at the cost of systematic violations of human rights. A new constitution was promulgated in 1981, and congressional elections have been scheduled for October, 1989. A "National Accord for Transition to Full Democracy" was mediated by the Catholic Church in 1985. The social reforms of the

    In 1985, Chile's population stood at 12 million, with an annual growth rate of 1.7%. 1984's infant mortality rate was 20/1000 live births and life expectancy was 67 years. The literacy rate was 94%. Of the work force of 3,841,000 in 1985, 15.9% were engaged in agriculture, forestry, and fishing; 31.3% were employed in industry and commerce; 38.6% were in the service sector; 8.7% worked in mining; and 4.4% were employed in construction. Chile's military junta is scheduled to be replaced by an elected legislature in 1990. The GDP was US $19.2 billion in 1984, with an annual real growth rate of 6.3%, and per capita GDP stood at US$1590. Inflation averages 23%. Industry comprises 21% of the GDP. Longterm prospects for the Chilean economy are influenced by a high debt service ratio, very low domestic savings and investment, the prospect of little or no increase in copper prices, and continuing problems in the domestic financial sector. In 1985-88, under the International Monetary Fund macroeconomic program, Chile will strive for moderate economic growth while managing its external debt servicing burden. PMID:12178144

    Full Text Available A lo largo de la historia de Chile es posible identificar diversos discursos sobre la formación docente. Una reciente modalidad es la mentoría, en la cual un profesor con experiencia trabaja con un profesor que recién ingresa al sistema educativo. En este artículo presentamos un análisis discursivo desde una perspectiva foucaultiana, de la sistematización de un programa piloto realizado en dos regiones de Chile. Del análisis se concluye que los horizontes de posibilidad desde los cuales emergen las prácticas de dicha experiencia, configuran un discurso de la formación en el cual el profesor debe ser capaz de gestionar su propio trabajo, del desarrollo docente como un emprendimiento individual. Estos horizontes de posibilidad promueven ciertas prácticas para la mentoría, como la problematización del trabajo individual docente en el aula; pero limitan otras, como la problematización colectiva de las políticas educativas.

En el mundo se han descrito 15 serotipos de App, en Chile solo los serotipos 1 y 5. La serotipificación requiere mucho tiempo, trabajo y dinero, actualmente se encuentran herramientas moleculares para realizar una "serotipificación" mediante la genotipificación de toxinas Apx. Así, se evaluaron 60 aislados de App provenientes de nueve empresas porcinas de producción intensiva distribuidas en distintas regiones de Chile, obtenidas desde pulmones de cerdos con lesiones compatibles con pleuroneumonía contagiosa porcina. Las bacterias fueron aisladas mediante los métodos tradicionales y confirmados por API, recolectados durante los años 2007, 2008 y 2009. Los resultados identificaron los genotipos correspondientes sólo a los serotipos 4, 6 y 7, los cuales se describen por primera vez en Chile, siendo el más frecuente el serotipo 7. En las diferentes zonas estudiadas, no existió un serotipo predominante, excepto en las regiones de O'Higgins y del Biobío en las cuales fue más frecuentemente aislado el serotipo 7. El presente estudio es el primer acercamiento con el fin de conocer la distribución de serotipos de App en Chile. Con el fin de conocer la real diversidad genética y serotipos de App en los diversos planteles en Chile es necesario realizar estudios que contemplen un mayor número de aislados.Actinobacillus pleuropneumoniae (App is the etiologic agent of porcine contagious pleuropneumonia, an important bacterial disease in intensive pig production.

    Full Text Available A pesar de que Chile ocupa lugares de vanguardia en los índices de democracia de Freedom House y Polity IV, la confianza de los ciudadanos en las distintas instituciones del sistema político, a 18 años de reinaugurada la democracia, deja en entredicho su solidez y consolidación. Esto, sumado a los bajos niveles de participación ciudadana y al preocupante incremento en la tasa de no inscritos en los registros electorales y de los abstencionistas, deja abierta una serie de preguntas en torno a la calidad de la democracia en Chile. Sobre la base de los resultados arrojados por las encuestas LAPOP 2006 y 2008, este artículo explora los niveles y determinantes de diferentes tipos de confianza institucional (definidos empíricamente hallados en los ciudadanos chilenos. El trabajo concluye que las positivas evaluaciones de los ciudadanos, respecto a los esfuerzos del gobierno para solucionar los principales problemas, están significativamente correlacionadas con el nivel de confianza hacia las instituciones democráticas.

    Full Text Available We use the sociological paradigm of Social Reproduction, proposed by the work of Pierre Bourdieu, to explain the wage gap in Chile, in opposition to the Neoclassical economic paradigm, currently hegemonic in the analysis of wage differentials. We expose and compare both theoretical paradigms and describe the case study highlighting the peculiarities of the Chilean neoliberal model. We estimate the salary of the Chilean population in order to explain the explanatory capacity of both theoretical approaches. We estimate two statistical models using the National Socioeconomic Characterization survey (CASEN 2009, firstly, the Neoclassical model based on Mincer equations and, secondly, a model that tries to empirically capture the explanatory factors specific to the paradigm of Social Reproduction. The results indicate that, in the case of Chile, the Reproductive model has greater explanatory power than the Neoclassical model, both for the whole group of workers, and for each of the generations of this group.Frente al paradigma económico neoclásico, hegemónico en la explicación del salario, se presenta el paradigma sociológico de la Reproducción Social, a partir de la obra de Pierre Bourdieu, para dar cuenta de la diferencia salarial en Chile. Después de exponer y comparar ambos paradigmas teóricos, se describe el caso de estudio, destacando las peculiaridades del modelo neoliberal chileno. Para comparar la capacidad explicativa de ambos enfoques, se estima el salario de los chilenos mediante la encuesta de Caracterización Socioeconómica Nacional 2009 (CASEN a partir de dos modelos estadísticos, el modelo neoclásico basado en las ecuaciones de Mincer y un modelo que trata de capturar empíricamente los factores explicativos propios del paradigma de la Reproducción Social.

Entre los mecanismos implicados se encuentra la producción de BLEE o AmpC asociados a alteraciones de las porinas o la presencia de carbapenemasas. Entre éstas, las de tipo KPC han cobrado especial relevancia dada su rápida diseminación. Se presenta el primer caso de aislamiento de una cepa de Klebsiella pneumoniae productora de KPC en un hospital de Santiago- Región Metropolitana, en un paciente trasladado desde Italia, con el antecedente de múltiples hospitalizaciones para tratamiento de un linfoma no Hodgkin y sometido a varios ciclos de quimioterapia y hemodiálisis. La cepa fue aislada desde un urocultivo al séptimo día de la llegada del paciente a Chile. Fue resistente a quinolonas, aminoglucósidos, cefalosporinas y carbapenémicos, sólo manteniendo sensibilidad a tige-ciclina y colistin. Por test fenotípicos resultó tener test de Hodge positivo y sinergia positiva con carbapenémicos más ácido borónico. Por reacción de polimerasa en cadena se demostró la presencia de β-lactamasas tipo TEM, SHV y KPC-2/KPC-3, no detectándose la presencia de otras serino-carbapenemasas de clase A o de metalo-β-lactamasas.Carbapenem resistance in Enterobacteriaceae is an emerging problem worldwide. Among the mechanisms involved are the production of ESBLs or AmpC associated with porins loss or the presence of carbapenemases.

    Full Text Available Resumen El caso de tejedoras mapuche de la IX Región de Chile nos permite reconsiderar los fenómenos de identidad cultural y etnicidad a la luz de las tensiones y procesos de subjetividad que median la construcción de memoria cultural. Se analiza tanto un escenario microgenético de los trabajos de identidad - como un escenario macrogenético, donde los procesos identitarios, las técnicas comerciales y religiosas del contexto mapuche se relacionan entre sí en permanente transmutación. Se discute el concepto de etnicidad con el fin de contribuir a ahondar en un fenómeno que está lejos de manifestarse como simple homogeneidad. Se realiza una discusión dando cuenta de la multiplicidad de tomas de posición en la experiencia de las tejedoras, enfatizando una mirada a la etnicidad como un proceso en permanente devenir, donde la memoria social del grupo reconduce una selección interesada de tradiciones orientando la construcción de una identidad potencial de cara al porvenir.

    Directory of Open Access Journals (Sweden)

    Teresa Durán

    2007-07-01

    Full Text Available El presente artículo gira en torno a la posibilidad de la antropología de estudiar lascondiciones de su propia existencia (Hubinger, 1997. Según entendemos, esta posibilidad significa no solo hacerse las preguntas claves relativas a sus características en tanto ciencia social sino a su vez poder otorgarse respuestas operacionales que guíen el proceso de autoanálisis desde su praxis. Creemos que el contexto de La Araucanía de Chile ha proporcionado un clima psicosocial desafiante para explorar esta posibilidad, así como para configurar respuestas provisionales, que son las que en esta oportunidad deseamos explicitar, orientadas no solo hacia la sociedad nacional, sino también a la regional y la local. La Araucanía es una denominación metafórica que representa un espacio territorial, social y cultural diverso que incuba nichos de desigualdad socioeconómica, así como variabilidades socioculturales que refieren, por un lado, a una cultura “originaria” con unatradición ancestral y, por otro, a una sociedad nacional que se auto-comprende como moderna. Espacio en que existiría una memoria que puede reconstruir historias que otorgan vida a dicho territorio y, al mismo tiempo, desconoce la historia o la pierde de vista debido a la imposición compulsiva de tendencias contemporáneas postmodernas y/o reificantes del colonialismo. Para la antropología local, este ha sido el escenario propicio para el planteamiento reiterativo de preguntas tales como ¿qué estudiar?, ¿cómo estudiar?, ¿para qué estudiar? Asimismo, ha sido un campo en el cual hemos estado ensayando un diálogo a través de nuestras prácticas profesionales, incorporando la historia donde ella está ausente (Durán, 2002; Durán y Berho, 2003; Carrasco y Eyzaguirre, 2005; Durán, 2005.

    Full Text Available El arsénico se encuentra en estado natural en rocas, suelo, agua, aire y es liberado al ambiente mediante fenómenos naturales tales como erupciones volcánicas, erosión de las rocas e incendios forestales, donde los microorganismos son esenciales para el ecosistema por su participación en diferentes procesos naturales. El objetivo del trabajo fue aislar bacterias resistentes a arsénico, desde muestras de rocas provenientes de la Quebrada Camarones, región Parinacota, Chile. Las rocas fueron cultivadas en un medio mineral adicionado con arsenito (500 ug/ml durante 7 días a temperatura ambiente y con agitación. Las cepas fueron aisladas en diferentes medios e identificadas mediante el sistema Rapid™NF plus. La capacidad de oxidar arsénico fue realizada mediante el ensayo cualitativo con nitrato de plata y la detección de genes aox, mediante RT-PCR. La reducción de arsénico fue evaluada mediante la amplificación de los genes ars por PCR. Se aislaron bacilos Gram negativos, no fermentadores, identificados como Pseudomonas alcaligenes y Wautersia solanacearum todas ellas capaces de tolerar concentraciones igual o mayor a 8 mM de As(III. Los análisis mediante RT-PCR demuestran la presencia de genes aox, que codifica para una enzima oxidante que cataliza la oxidación de As(III a As(V. La capacidad de oxidar arsenito de las cepas aisladas, favorecería la colonización de otras especies no tolerantes a arsénico importantes en los ciclos biogeoquímicos.Arsenic is naturally present in rocks, soil, water, and air, being released to the environment by natural processes such as volcanic eruptions, and erosion rock.

    Full Text Available Studying the Chilean foreign policy in its historical and international context, it stands out that the arrival of democracy in Chile allowed its successful international reintegration. An essential tool to obtain this result was the subscription of Free Trade Agreements (FTA, of which the FTA between Chile and Canada is a good example of how this type of agreement can impel a bilateral relation. Nowadays, the deepening of the cooperation between Chile and Canada in a great variety of subjects, not only economical, became a relevant objective of the Chilean foreign policy. This is the result of their foreign policy convergences and the necessity for a weaker State to associate himself with more powerful fellows to influence the world politics.

    Full Text Available RESUMEN Este artículo pretende convertirse en una aproximación a la visión que se proyectó en Chile de la transición a la democracia en España partiendo para ello de una mirada concreta: la que sobre este acontecimiento dio el más importante medio de difusión escrito del país, El Mercurio de Santiago. A través de una pormenorizada búsqueda en su sección de opinión y especialmente en el apartado editorial se ha trazado una panorámica que intenta describir los modos en que este rotativo fue asimilando los acontecimientos que transformaron el Estado español de una régimen dictatorial autoritario a otro de plenas garantías democráticas y las maneras en que el periódico los vertió sobre sus lectores convirtiéndolos en opinión publicada. En pos de este objetivo se ha intentado especialmente indagar en aquellas cuestiones cuyo tratamiento serviría al diario de excusa para posicionarse ideológicamente sobre una doble realidad: el momento político español caracterizado por el cambio político y la coyuntura chilena, inmersa en el régimen dictatorial de Pinochet que empezaba ya entonces a debatirse entre su continuidad y su institucionalización. Palabras Clave: España, Transición, El Mercurio. ABSTRACT This article aims to become an approximation to the idea projected in Chile about the transition to democracy in Spain from a very specific view: the one showed in the most important writing media in the country, El Mercurio de Santiago. Through a thorough search in its opinion section and especially the publishing section, we have outlined an overview which attempts to describe how this newspaper assimilated the events which made the authoritarian dictatorial regime of the Spanish state turn into a fully guaranteed democracy and how newspapers poured it onto their readers making it a published opinion. For this purpose, we have been trying to inquire especially into those matters which would be used like an excuse for their

Se sostiene que la preocupación por los constantes problemas sociales que afectaron a la región, derivados de los ciclos de extracción salitrera, orientó la acción pastoral al asentamiento de las bases del desarrollo de la paz social y del reconocimiento del obrero y sus demandas como símbolos del papel de la Iglesia en la zona. El objetivo fue consolidar un discurso que vinculara a los obreros a la institución eclesiástica en cuanto que baluarte de sus derechos y promotora del equilibrio entre el capital y el trabajo.

    Full Text Available La coyuntura actual de políticas educativas de cobertura, calidad, equidad y diversidad imponen desafíos a los establecimientos educacionales, especialmente a los municipales, los cuales deben desarrollar estrategias orientadas a satisfacer las necesidades de los estudiantes que se encuentran en sus aulas, capitalizando sus fortalezas. Esta investigación es de naturaleza exploratoria con una metodología mixta explicativa. Se presentan los resultados de la primera fase del estudio que corresponde al análisis de proyectos educativos y a la caracterización de estudiantes sobresalientes. Se analizaron los resultados obtenidos de 1.536 estudiantes provenientes de 18 establecimientos educacionales de las comunas de Antofagasta y Calama (Chile. A partir del análisis y de acuerdo a indicadores de talento académico, la muestra fue caracterizada en cuatro grupos de estudiantes: estudiantes sobresalientes, sub-nominados, sobre-exigidos y promedio. La categoría de estudiantes subnominados plantea cuestionamientos referentes a la metodología de identificación de estudiantes con talento en los programas chilenos, fuertemente cimentada en la nominación docente. Se advierte la necesidad de generarrutas alternativas, como la autonominación. Para concluir, se hacen algunas sugerencias alrededor de las políticas públicas en relación con la educación para estudiantes sobresalientes en particular para Chile, pero pueden ser en buena medida transferidas a otros casos a través de Iberoamérica.

La base empírica de la investigación proviene de entrevistas semi-estructuradas con hablantes urbanos de Santiago, Temuco y Concepción durante 2006 y 2007. Las representaciones sobre episodios autobiográficos permiten configurar un itinerario de análisis que se centra en: los espacios sociales favorables para el uso del mapudungún, y las nuevas experiencias de adquisición y recuperación de la lengua. A través de la reflexión y el testimonio de los hablantes es posible constatar eventuales procesos de cambio sociocultural y resistencia étnica que buscan compensar el modelo diglósico imperante que limita las opciones de uso del mapudungún en el contexto urbano chileno.Urban migration triggers new processes of ethnic identity among mapuche people in Chile. Given this, we propose a new approach towards the conditions that rules the use and transmission of mapudungun among urban speakers in the context of a general linguistic shift process. The empirical base of the investigation was obtained in semi-structured interviews with urban speakers of mapudungun in Santiago, Temuco and Concepción, between 2006 and 2007. The representations about autobiographic episodes make possible to follow an analytical path that focuses on the social spaces identified for the use of mapudungun, and the new experiences of acquisition and re-use of the language. We state that through the speakers' testimony it is possible to reveal processes of socio-cultural change and ethnic resistance that seeks to counterbalance the diglossic model that rules the use options of mapudungun in the

Este trabajo tiene como objetivo determinar los flujos de emisiones in situ de CO2 y N2O desde un suelo derivado de cenizas volcánicas bajo diferentes prácticas de manejo agronómico determinando su variación estacional. Las muestras gaseosas fueron obtenidas desde el espacio aéreo de cámaras cerradas no-fijas en una rotación anual de cultivos bajo sistema de cero labranza en un Andisol del Sur de Chile (36° S. Dos fuentes de N (NH4+ y NO3- y fertilización amoniacal más dos dosis de encalado (0.5 y 1 Mg ha-1 fueron considerados como tratamientos. Los flujos de CO2 y N2O fueron determinados periódicamente en un período de 1 año y variables de suelo tales como temperatura, contenido de agua, y N mineral fueron registrados. Los resultados muestran que los flujos de CO2 responden a patrones de estacionalidad. No fue evidenciado un efecto cuando fue considerada la práctica de manejo del cultivo, con un máximo de 53.2 ± 8.5 kg CO2-C ha-1 d-1 en la estación húmeda de otoño, y un mínimo de 9.7 ± 2.1 kg CO2-C ha-1 d-1 para verano, estación seca de otoño e invierno. El flujo de N2O fue altamente variable en el año y no muestra influencia de tratamientos o estacionalidad, con un promedio de 2.6 ± 0.6 g N2O-N ha-1 d-1. Variaciones de N mineral del suelo no están relacionadas a los flujos de GHG como una variable sola. Los resultados indican que un Andisol bajo sistema de cero labranza en el Sur de Chile tiene un bajo potencial de emisiones de N2O, y las mayores emisiones de CO2 son producidas principalmente en estaciones húmedas (otoño húmedo y/o primavera.

    Full Text Available The following article describes the role of the written press of Chile and Peru in the development of some conflictive relations between these countries. The analysis indicates that there are three discursive strategies to legitimize mutual rejection, such as the negative representation of otherness, the exaltation of competition for economic success, and the promotion of national identity based on the values attributed to the military of the Pacific War. The conclusions propose two measures to transform these discourses: the development of social publicity campaigns and the creation of a code of ethics that establishes recommendations for appropriate journalistic treatment of the relations between these countries.

    Full Text Available El Subsistema Seguridades y Oportunidades del Ingreso Ético Familiar de Chile fue aprobado en el año 2012 y comenzó su operación efectiva el año 2013. A lo largo de los últimos años ha beneficiado a alrededor de 150.000 hogares entregando transferencias monetarias condicionadas y no condicionadas. Asimismo, se complementa con la implementación de acompañamientos familiares de tipo psicosocial y sociolaboral que buscan mejorar las relaciones internas de las familias, la empleabilidad de las personas mayores de edad y la vinculación del hogar con el resto de los programas sociales. Sin embargo, su implementación no ha estado exenta de problemas debido a que cumple de manera parcial con los requerimientos propios del enfoque de derechos económicos, sociales y culturales. El artículo finaliza con un conjunto de observaciones que revelan la existencia de desafíos para mejorar el diseño y la implementación del IEF, que van de la mano con una aplicación adecuada de los principios que componen un enfoque basado en derechos humanos.

    Full Text Available El problema de la desigualdad en Chile ha sido abordado desde diferentes puntos de vista como la cuestión de la distribución de la riqueza o el acceso a los derechos sociales. Es este trabajo se observa el mismo problema pero desde la perspectiva recientemente esbozada por los movimientos sociales: la del racismo ambiental o la desigual distribución de los deshechos del desarrollo y el consumo. De esta manera se revisan sucintamente los principales conflictos que han surgido en el último tiempo a lo largo del país entre empresas públicas y privadas y comunidades locales y originarias. Así mismo se examinan las formas de organización que estas últimas han asumido y el estado actual de articulación entre ellas. De la revisión de la situación se concluye que estamos ante el surgimiento de un actor de nuevo tipo, que surge de las contradicciones del Chile neoliberal y que se diferencia del movimiento ecologista por vincular sus reivindicaciones a la defensa del territorio y al derecho a la autodeterminación de los pueblos.

Para esto, tomamos los datos procedentes de un contexto ubicado en la cuenca superior del río Maipo: Caletón Los Queltehues, y escogimos, de su secuencia ocupacional, los componentes Arcaico IV y Alfarero temprano (5000 a 1000 AP. Los resultados de los análisis no arrojaron mayores variaciones entre ambos períodos en términos de taxones explotados, frecuencia de partes esqueletarias, modificaciones culturales y fragmentación de los restos óseos. De manera similar, las materias primas, las categorías morfofuncionales y los tipos de desechos líticos se observaron relativamente constantes. Sólo se registraron cambios en la tasa de la depositación, la frecuencia de modificaciones naturales y la diversidad de actividades de uso/descarte lítico, las que son interpretadas como una tendencia hacia una variación en la recurrencia e intensidad de la ocupación, pero no en cuanto a su funcionalidad.This article evaluates long-term trends in change and continuity of lithic and faunal use strategies in hunter-gatherer contexts in the central Chilean cordillera from technological and behavioral perspectives.

    Full Text Available Two stations representing coastal and shelf environments (bay of Concepción and adjacent shelf, respectively were sampled in order to assess benthic nitrogen fluxes. During the study period anomalously high oxygen bottom waters conditions were observed, coinciding with the 1997-1998 El Niño event. From both sites, intact sediment cores were collected for incubation experiments to directly estimate total ammonium fluxes. Pore-water chemistry was also assessed to estimate diffusive fluxes of nitrogen compounds (NH4+, NO3- and NO2-. The NH4+ flux from incubation experiments ranged from 0.55 to 2.18 mmol m-2 day-1 in the inner bay and from 1.84 to 2.14 mmol m-2 day-1 on the shelf. NO3- diffusive fluxes to the sediments were observed in the bay in March (-17 x 10-2 mmol m-2 day-1and on the shelf in November (-2.7 x 10-2 mmol m-2 day-1, associated with the lowest NH4+ diffusive fluxes and coincident with a stronger gradient of Eh in the first centimeters of the sediments. Besides, total NH4+ fluxes lower than in normal periods were observed, suggesting the influence of less reducing conditions, consequence in turn of the lower fluxes of particulated organic material and higher dissolved oxygen in the bottom waters. These conditions were probably imposed by the El Niño event. On the other hand, and relative to previous reports, an increase of irrigation coefficients (DI was estimated. Thus, the flux extension of other nitrogen compounds could have acquired relevance in relation to NH4+ fluxes during the study periodSe analizaron los flujos de compuestos nitrogenados desde los sedimentos en dos áreas representativas de condiciones costeras y de plataforma (Bahía Concepción y plataforma adyacente, respectivamente.

    Chile has a great tradition of producing and exporting copper. Over the last several decades, it has become the first producer on an international level. Its copper reserves are also the most important on the planet. However, after years of mineral exploitation, the ease of extracting copper oxides and ore copper content has diminished. To keep the production level high, the introduction of new technologies has become necessary. One that has been successful is bioleaching. Chile had the first...

    Full Text Available Para un sector de la crítica y de la academia chilena, la gran novela de la Dictadura es una asignatura pendiente. En este artículo se problematiza este tema mediante la formulación de una hipótesis según la cual una serie de novelas aparecidas en Chile entre 1977 y 2006 cumplen con la función de narrar -desde su fragmentariedad- las causas y consecuencias del 11 de septiembre de 1973. Así, busca plantear las bases epistemológicas e históricas que posibiliten llevar a cabo una investigación de mayor alcance acerca del problema del papel de la novela durante y después de la Dictadura.For many critics and scholars the great novel of the dictatorship's period in Chile still remains a pending matter. This article, on the contrary, hypothesizes on the existence of a significant number of novéis published in Chile between 1977 and 2006, which out of their fragmentary character and peculiarity give a proper account of the causes and consequences of the coup d'état held on September llth 1973. The article seeks to set a preliminary basis for an epistemological discussion and further major research about the role of the Chilean novel, in the historical context of post modernity, during and after the dictatorship's era.

    2014-08-01

    According to recent surveys, there is a high prevalence of domestic violence (DV) in Chile. A systematic review was conducted in PubMed, Scielo, and Lilacs with the MesH terms "Chile", "Mental Health", "Health", "Domestic Violence", to explore the impact of DV on health in Chile. Eleven studies fulfilled the inclusion criteria. Two studies were prospective, exploring the influence of DV on maternal-infant health. Nine studies explored the influence of DV on mental health in adults. DV was associated with deranged mental health indicators specially anxiety and depressive symptoms and suicidal ideation. Similar results were observed among mothers who were victims of violence and their children. It is concluded that DV is a complex phenomenon with serious effects on health. However the number of studies on the subject is low and new follow up studies are required. Predictive models for DV and effective preventive measures are urgently needed. PMID:25424674

Se siguió la etnoenfermería con el objeto de averiguar la perspectiva femenina étnica, e identificar las prácticas beneficiosas y de riesgo para su salud. La investigación tuvo como participantes claves a 17 mujeres. En la consolidación de la muestra se aplicaron los criterios de saturación de datos. En los resultados se evidenció la relación de las mujeres con su propio cuerpo, su defensa y fortificación desde la menarquia como fase preparatoria de sus funciones reproductivas, hasta cuando aparece la menopausia. De acuerdo con su cultura, si no tienen en cuenta estas prácticas tradicionales, sufrirán diversas dolencias en la etapa final de su periodo de procreación. Los cuidados sobresalientes se relacionan con el significado de la sangre, así como con el ejercicio de la sexualidad, la limpieza, la alimentación especial y el equilibrio que se debe guardar entre el calor y el frío. Las entrevistadas atribuyen a la menopausia cambios en su cuerpo, en sus diferencias emocionales de conducta y en las expectativas de la sexualidad. Para el presente estudio estos hallazgos se agruparon en tres temas principales: sentir los profundos cambios en la vida: el cuerpo; sentir los cambios en los estados de ánimo; y vivir la sexualidad.

    Salmonella are gram-negative bacilli within the family Enterobacteriaceae. They are the cause of significant morbidity and mortality worldwide. Animals (pets) are an important reservoir for nontyphoidal Salmonella, whereas humans are the only natural host and reservoir for Salmonella Typhi. Salmonella infections are a major cause of gastroenteritis worldwide. They account for an estimated 2.8 billion cases of diarrheal disease each year. The transmission of Salmonella is frequently associated with the consumption of contaminated water and food of animal origin, and it is facilitated by conditions of poor hygiene. Nontyphoidal Salmonella infections have a worldwide distribution, whereas most typhoidal Salmonella infections in the United States are acquired abroad. In the United States, Salmonella is a common agent for food-borne–associated infections. Several outbreaks have been identified and are most commonly associated with agricultural products. Nontyphoidal Salmonella infection is usually characterized by a self-limited gastroenteritis in immunocompetent hosts in industrialized countries, but it may also cause invasive disease in vulnerable individuals (eg, children less than 1 year of age, immunocompromised). Antibiotic treatment is not recommended for treatment of mild to moderate gastroenteritis by nontyphoidal Salmonella in immunocompetent adults or children more than 1 year of age. Antibiotic treatment is recommended for nontyphoidal Salmonella infections in infants less than 3 months of age, because they are at higher risk for bacteremia and extraintestinal complications. Typhoid (enteric) fever and its potential complications have a significant impact on children, especially those who live in developing countries. Antibiotic treatment of typhoid fever has become challenging because of the emergence of Salmonella Typhi strains that are resistant to classically used first-line agents: ampicillin, trimethoprim-sulfamethoxazole, and chloramphenicol.

    The main radioactive waste management issues to be faced by the Chilean Nuclear Energy Commission (CCHEN) are discussed herein. Research reactor spent fuel management is the most outstanding challenge at the beginning of the 21st century. Interim storage appears to be the most promising alternative, allowing fuel safekeeping until a definitive step is taken. The situation regarding radioactive waste resulting from radioisotope applications in Chile will not undergo considerable change in the near future. Low and intermediate level radioactive waste management is being safely performed followed by interim storage of conditioned wastes. The strategy in the radioactive waste management plan, to be described as well, is meant to ensure the safe storage of radioactive wastes produced in Chile. (author)

    A significant increase in the number of isolations of Salmonella enteritidis has been observed in Argentina since 1986. Outbreaks of foodborne diseases in humans were associated with the consumption of raw or undercooked hens' eggs. Between 1986 and the first 6 months of 1993 there were 150 outbreaks reported, affecting more than 6000 persons. A total of 71.3% of these outbreaks were confirmed by stool cultures, and 47.3% by bacteriological study of the food implicated in the outbreak. A permanent surveillance of salmonellosis is imperative, taking into account the persistence of Salmonella enteritidis isolations in sporadic cases and in new outbreaks. PMID:8155472

    ESO, the European Southern Observatory, in reply to questions raised by the international media, as well as an ongoing debate about the so-called "Paranal case" in Chilean newspapers, would like to make a number of related observations concerning its status and continued operation in that country [1]. THE ESO OBSERVATORY SITES IN CHILE The European Southern Observatory, an international organisation established and supported by eight European countries, has been operating more than 30 years in the Republic of Chile. Here ESO maintains one of the world's prime astronomical observatories on the La Silla mountain in the southern part of the Atacama desert. This location is in the Fourth Chilean Region, some 600 km north of Santiago de Chile. In order to protect the La Silla site against dust and light pollution from possible future mining industries, roads and settlements, ESO early acquired the territory around this site. It totals about 825 sq. km and has effectively contributed to the preservation of its continued, excellent "astronomical" quality. Each year, more than 500 astronomers from European countries, Chile and elsewhere profit from this when they come to La Silla to observe with one or more of the 15 telescopes now located there. In 1987, the ESO Council [2] decided to embark upon one of the most prestigious and technologically advanced projects ever conceived in astronomy, the Very Large Telescope (VLT). It will consist of four interconnected 8.2-metre telescopes and will become the largest optical telescope in the world when it is ready. It is safe to predict that many exciting discoveries will be made with this instrument, and it will undoubtedly play a very important role in our exploration of the distant universe and its many mysteries during the coming decades. THE VLT AND PARANAL In order to find the best site for the VLT, ESO performed a thorough investigation of many possible mountain tops, both near La Silla and in Northern Chile. They showed

    Salmonellosis outbreaks involving typhoid fever and human gastroenteritis are important diseases in tropical countries where hygienic conditions are often not maintained. A rapid and sensitive method to detect Salmonella spp., Salmonella Typhi and Salmonella Typhimurium is needed to improve control and surveillance of typhoid fever and Salmonella gastroenteritis. Our objective was the concurrent detection and differentiation of these food-borne pathogens using a multiplex PCR. We therefore designed and optimized a multiplex PCR using three specific PCR primer pairs for the simultaneous detection of these pathogens. The concentration of each of the primer pairs, magnesium chloride concentration, and primer annealing temperature were optimized before verification of the specificity of the primer pairs. The target genes produced amplicons at 429 bp, 300 bp and 620 bp which were shown to be 100% specific to each target bacterium, Salmonella spp., Salmonella Typhi and Salmonella Typhimurium, respectively.

    Salmonellosis is a disease that represents a major public health concern in both developing and developed countries. The aim of this article is to evaluate the public health burden of Salmonella illness in Lebanon. The current scope of the Salmonella infection problem was assessed in relation to disease incidence and distribution with respect to age, gender and district. Factors that provide a better understanding of the magnitude of the problem were explored and highlighted. Data reported to the Epidemiologic Surveillance Department at the Lebanese Ministry of Public Health between 2001 and 2013 was reviewed. Information obtained was compared to information reported regionally and globally. The estimated true incidence was derived using multipliers from the CDC and Jordan. A literature review of all published data from Lebanon about Salmonella susceptibility/resistance patterns and its serious clinical complications was conducted. The estimated incidence was 13·34 cases/100 000 individuals, most cases occurred in the 20-39 years age group with no significant gender variation. Poor and less developed districts of Lebanon had the highest number of cases and the peak incidence was in summer. Reflecting on the projected incidence derived from the use of multipliers indicates a major discrepancy between what is reported and what is estimated. We conclude that data about Salmonella infection in Lebanon and many Middle Eastern and developing countries lack crucial information and are not necessarily representative of the true incidence, prevalence and burden of illness.

    Abstract Salmonellosis is the main cause of human bacterial gastroenteritis in most European countries. Infections with Salmonella is usually subclinical, whereas clinical cases show symptoms with a wide range of severity. Infection is most commonly associated with the consumption of meat, especially poultry or pork, and eggs and their products. Salmonella can enter the food chain at any point throughout its length. The principal reservoir of Salmonellae is the gastrointestinal tract of mamma...

    Full Text Available CONTEXT: Salmonella has been identified as a causative agent of acute pancreatitis. OBJECTIVE: We prospectively evaluated the frequency of acute pancreatitis, pancreatic enzyme elevation and morphological pancreatic abnormalities in patients with Salmonella infection. SUBJECTS: Thirty consecutive patients with salmonellosis (Salmonella enterica serovar Enteritidis: n=25; Salmonella enterica serovar Typhimurium: n=5 and 30 sex- and age-matched healthy subjects were studied. MAIN OUTCOME MEASURES: All subjects underwent serum amylase and lipase determination and ultrasonography. RESULTS: None of the subjects developed acute pancreatitis. Two patients (6.7% and two controls showed serum amylase activity above the upper reference limit whereas, in five patients (16.7% and one control subject (3.3%, the serum lipase activity appeared above the upper reference limit. Salmonella infection significantly increased serum activity of lipase (P less than 0.001 while it did not significantly affect serum amylase levels (P=0.204. Serum lipase activity was significantly higher in patients infected by Salmonella enterica serovar Typhimurium than in those infected by Salmonella enterica serovar Enteritidis (P=0.012. Ultrasonography did not show pancreatic abnormalities in any of the subjects. CONCLUSIONS: Our data demonstrated an elevation of serum lipase activity in gastroenteritis due to Salmonella infection, but this elevation does not seem to have clinical significance. The elevation of serum lipase seems to be particularly related to infection from Salmonella enterica serovar Typhimurium.

La presente revisión incluye: historia de la enfermedad, reservorio, modos de transmisión, patogenia, cuadro clínico, diagnóstico, tratamiento y medidas de prevenciónSince 1993, 204 cases of Hantavirus cardiopulmonary syndrome (HCPS occurred in Chile. Epidemic began in the south and moved thereafter to the northern regions. The disease affected predominantly young males, who worked in agricultural labours or as timber workers. The HCPS in Chile is caused by the Andes virus. The reservoir is the wild rat Oligoryzomis longicaudatus distributed from the III to the XII Region. The clinical features are similar to those described for Sin Nombre Virus. The disease has a prodromal stage characterised by fever, muscular pain, with or without gastrointestinal manifestations, followed by the rapid onset of respiratory insufficiency and haemodynamic unstability. Andes virus courses more often with haemorrhagic disorders and overt renal failure, than Sin Nombre Virus. The initial mortality was over 50% and declined to 33,3% in the last year.

  14. The biomethane potential in Chile

    International Nuclear Information System (INIS)

    Within the last decade natural gas gained considerable importance in Chile. The contribution of natural gas within the energy system will increase in the future by predicted 3.6% annually until the year 2015. Due to limited resources within its own country, the energy system of Chile depends on natural gas imports preferential from Argentina. Therefore, the aim of several stakeholders from policy and industry is to reduce the share of imported primary energy within the overall energy system. In order to reach this goal, the use of domestic resources and particularly the utilisation of biomass as one of the most important renewable sources of energy in Chile could play an important role. Against this background, the goal of this paper is the analysis of the technical potentials of biomethane as a substitute for natural gas. For the production of biomethane the anaerobic or bio-chemical (i.e. Biogas) as well as the thermo-chemical conversion pathways (i.e. Bio-SNG) are considered. The results of this analysis show that biomass converted to biomethane is a promising energy provision option for Chile and it contributes to the reduction of greenhouse gas emissions

    Gunnarsson E

    2002-03-01

    Full Text Available In 1995 several outbreaks of food poisoning in humans occurred in Iceland, that were traced to salmonella contamination of singed sheep heads. This prompted us to study the prevalence of salmonella infection in sheep and to trace where and how infection might have occurred. Faecal, intestinal contents and tonsillar samples were collected in the spring and autumn from sheep on 50 farms in the southwestern part of the country, where salmonellosis had been detected and from 5 farms in the northwestern part of the country. All faecal samples from the southwest were negative, whereas samples from 3 farms obtained in the autumn in the northwest were positive. Tonsillae taken in the autumn were positive in sheep from 3 farms in the southwest and 2 in the northwest. Our results show that salmonella infection is rare in Icelandic sheep but healthy carriers may harbour the bacteria in tonsillae. Salmonella was not detected in drainage from slaughterhouses nor in singed sheep heads.

    1993-12-01

    Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage. PMID:8085073

    Full Text Available Plant essential oils are natural products extracted from plants and because of their antimicrobial properties can be used as natural additives in foods. They are also useful for decontamination of food-borne pathogens and can be a safe additive in foods. The antimicrobial activities of essential oils belonging to Saturiea hortensis, Thymus vulgaris, Mentha polegium, Cuminum cyminum, Lavandula officinalis and Mentha viridis L. (spearmint were investigated at different concentrations (0.1, 0.3, 0.5, 1, 2, 5 and 10%v/v against Salmonella typhimurium, Salmonella paratyphi A and Salmonella paratyphi B by using the agar well diffusion method. Essential oils showed inhibitory effect on Salmonella spp. in the agar well diffusion assay. In addition, the capability of essential oils for decontamination of minced row beef, ground beef, minced raw chicken and minced raw fish inoculated with Salmonella spp. at 0.1 and 0.5%v/v were assessed. Reduction of the Salmonella spp. population was observed following the inoculation of the cultures with 0.1 and 0.5%v/v essential oils.

  17. Reveal for Salmonella test system.

    The Reveal for Salmonella (RSS) test system is a presumptive qualitative test that detects the presence of Salmonella organisms in foods within 21 h total testing time, allowing the user to release negative products 24 h earlier than when using other rapid test kits. Foods are enriched with a proprietary resuscitation medium called Revive and then selectively enriched with either Selenite Cystine or Rappaport-Vassiliadis selective media. The enriched culture is used to inoculate the RSS detection device, which initiates a lateral flow through a reagent zone containing anti-Salmonella antibodies conjugated to colloidal gold particles that capture antigens present in the culture. The antigen-antibody complex migrates farther and is captured by an additional anti-Salmonella antibody, causing the colloidal gold to precipitate and form a visual line, indicating a positive result. A procedural control line also will form regardless of the presence of Salmonella organisms to indicate the test is working properly. Existing AOAC Official Methods for Salmonella organisms require a 48 h enrichment before testing. Hence, a food product has to be held before release, adding extra cost to the company and the consumer. The RSS test system was evaluated by quantitative spiking studies. Although AOAC encourages inclusion of naturally contaminated foods, almost all microbiological AOAC validation studies have been performed with artificially contaminated foods for absolute control over the study. The RSS test system is designed to test many food types for Salmonella organisms and has a limit of detection of 5-10 colony-forming units (cfu)/25 g with a false-negative rate of < 1% and a false-positive rate of < 5.0%. It showed an 81% overall agreement with the traditional procedure of the U.S. Department of Agriculture's Food Safety Inspection Service. PMID:10367381

    Salmonellosis is a significant zoonotic disease which has a considerable economic impact on the egg layer industry. There is limited information about the prevalence of Salmonella spp. in backyard chickens. The current study was conducted to determine the prevalence of Salmonella in backyard chickens, and the associated virulence of any serovars identified. Hundred and fifteen pooled samples from 30 backyard flocks in South Australia were screened. Four flocks tested positive for Salmonella spp. The overall Salmonella isolation rate in the current study was 10.4%. The estimated prevalence at individual bird level was 0.02% (95% CI 0.025-0.975). The serovars isolated were Salmonella Agona, Salmonella subsp 2 ser 21:z10:z6 (Wandsbek) and Salmonella Bovismorbificans. All Salmonella isolates tested positive for the prgH, orfL and spiC genes. The Salmonella subsp 2 ser 21:z10:z6 (Wandsbek) had the most antibiotic resistance, being resistant to ampicillin and cephalothin and having intermediate resistance to florphenicol. All of the Salmonella Agona had intermediate resistance to the ampicillin, while the Salmonella Bovismorbificans were susceptible to all antibiotics tested. With the increased interest of keeping backyard chickens, the current study highlights the zoonotic risk from Salmonella spp. associated with home flocks. PMID:25899620

    In recent years, a new emphasis has been placed on increasing solid fuel availability in Chile, to reach the northern mining operations where demand for power is soaring. The south of the country is well served by hydroelectric power plants (2.3 million kW). The coal industry has doubled its capacity to cope with increased copper production - the Tocopilla power plant at the Chuquicamata copper mine has been converted from oil to coal - and there has been a major investment programme in the steel industry. In 1986, 1.4 million tons of coal was mined, mostly from the Provinces of Concepcion and Arauco, the remainder from Valdivia. Since then, 70 million US dollars has been invested by COCAR SA in the Pecket deposit near Punta Arenas. Coal from Pecket should cost around 26 dollars/t compared with 60 dollars/t for underground coal. It should support an expanded coal market in Chile and may also be able to compete in the Brazilian and Argentine markets. Reserves are estimated at over 200 Mt. Petroleum reserves in Tierra del Fuego are nearly exhausted; seismic surveys in the Atacama desert are promising.

    Full Text Available Los humedales boscosos de agua dulce son áreas naturalmente inundadas o saturadas, que sustentan vegetación boscosa hidrófila, están presentes en todo el mundo, y en Chile son conocidos como "pitrantos, hualves o hualhues". El presente estudio entrega el estado del conocimiento de estos humedales en Chile, mediante una descripción de sus características biológicas, fisicoquímicas e hidrodinámicas, identificando las principales amenazas para su conservación y las principales necesidades de investigación. Estos ambientes pueden presentar inundación permanente o temporal, dependiendo de un conjunto de procesos microclimáticos, biológicos y edafológicos. Su vegetación, del tipo hidrófila boscosa, es dominada por especies de la familia Myrtaceae. Tanto el comportamiento hídrico como la estructura vegetacional destacan dentro de los aspectos que determinan directamente las características fisicoquímicas del agua y los patrones de distribución de las comunidades biológicas. Los humedales boscosos de Chile han sido ampliamente estudiados desde un punto de vista vegetacional y florístico, pero carecen de estudios limnológicos, hidrológicos o faunísticos básicos, de lo cual deriva un total desconocimiento en relación a su funcionamiento a nivel ecosistémico y los efectos que pueden tener las actividades humanas en sus cuencas (e.g., agrícola, ganadera, forestal sobre sus componentes hídricos y biológicos. A pesar de ser ecosistemas de gran relevancia cultural y ecológica, se identifican importantes falencias en cuanto a su estado de conservación, al no encontrarse protegidos por las actuales herramientas de conservación existentes en el país. Por lo tanto, emergen como ecosistemas únicos, de relevancia mundial, prácticamente desconocidos en Chile y de gran interés para el desarrollo de numerosas líneas de investigación, aunque su alta susceptibilidad ante perturbaciones de origen antrópico amenaza su permanencia

    Full Text Available Alstroemeria (Alstroemeriaceae is an endemic genus of South America with two major distribution centers in the continent: Chile and Brazil. In Chile the genus is distributed from the North, near Iquique (20º13’ S, 70º09’ W to the Chilean and Argentine Patagonia (53º10’ S, 70º54’ W. The central zone of Chile presents the highest number of species.

A comparative karyotype study was made between a population of A. presliana subsp. presliana and a population of A. presliana subsp. australis Ehr. Bayer. Both populations presented asymmetric karyotypes, with 2n = 2x = 16 chromosomes, but with different chromosome formulae: A. presliana subsp. presliana has a haploid formula with 4m + 1sm-sat + 1st-sat + 2t, i.e., four pairs ofmetacentric chromosomes, one submetacentric pair with satellite, one subtelocentric pair with satellite, and two telocentrics pairs. A. presliana subsp. australis has a formula with 2m + 1m-sat + 1sm + 4t chromosomes, i.e., two pairs of metacentric chromosomes, one metacentric pair with satellite, one submetacentric pair, and four telocentrics chromosomes. These results indicated that the karyotype of the subspecies is very different, and it would be possible to recognize A. presliana subsp. australis as a new species.Alstroemeria (Alstroemeriaceae es un género endémico de Sudamérica y presenta dos grandes centros de distribución: Chile y Brasil.

    Full Text Available Bacteria of the genus Salmonella are highly adapted for the growth in both humans and animals and cause a wide spectrum of disease. The growth of Serotypes S. typhi and S. paratyphi is restricted to human hosts, in whom these organisms cause enteric (typhoid fever. The remaining Serotypes (non typhoidal Salmonella or NTS can colonize the gastrointestinal tracts of the broad range of animals, including mammals, reptiles, birds and insects. The usual clinical presentation of non-typhoidal salmonellae (NTS infection is self limited gastroenteritis; however bacteremia and focal extra intestinal infection may occur. However salmonella localization to the skin presenting as cutaneous ulceration is regarded as a rare event. Rates of morbidity and mortality associated with NTS are highest among the elderly, infants, and immunocompromised individuals, including those with hemoglobinopathies, HIV infection, or infections that cause blockade of the reticuloendothelial system. We isolated S.infantis in 50 years old man with left leg cellulitis. The serotype was confirmed at Central Research Institute, Kasauli.

    This paper describes a village application in Chile. The objective was to demonstrate the technical, economic and institutional viability of renewable energy for rural electrification, as well as to allow local partners to gain experience with hybrid/renewable technology, resource assessment, system siting and operation. A micro-grid system is viewed as a small village system, up to 1200 kWh/day load with a 50 kW peak load. It can consist of components of wind, photovoltaic, batteries, and conventional generators. It is usually associated with a single generator source, and uses batteries to cover light day time loads. This paper looks at the experiences learned from this project with regard to all of the facets of planning and installing this project.

  3. Salmonella – A Brief Summary

    Directory of Open Access Journals (Sweden)

    Nurmi Esko

    2002-03-01

    Full Text Available Abstract Salmonellosis is the main cause of human bacterial gastroenteritis in most European countries. Infections with Salmonella is usually subclinical, whereas clinical cases show symptoms with a wide range of severity. Infection is most commonly associated with the consumption of meat, especially poultry or pork, and eggs and their products. Salmonella can enter the food chain at any point throughout its length. The principal reservoir of Salmonellae is the gastrointestinal tract of mammals and birds, but Salmonellae are able to survive and even multiply in many external environments. In Norway, Sweden and Finland cost effective prevention methods have been used for several years to prevent and control Salmonellea infections. In addition, competitive exclusion (CE and vaccination might be relevant as biological methods to prevent colonisation of bird intestines by enteropathogens, especially Salmonella. Antibiotic drug resistance has been a problem since the start of the antibiotic era. The cause for anxiety is that more and more bacteria are becoming resistant, often to a whole range of antibiotics. The debate on the use of antimicrobials in veterinary medicine and animal production dates back almost as long as the use itself. There is a clear evidence to show that antibacterial agents given to animals for growth promotion, prophylactic purposes or treatment induce a rise in the number of antibiotic resistant strains isolated from the animals. These bacteria may be transmitted to humans by several possible routes. There are thus strong arguments for preventive efforts which have to be directed towards identifying real critical control points (HACCP throughout the whole food chain, which starts from the farm and ends at the consumer's table.

  7. Biomonitoring air pollution in Chile

    International Nuclear Information System (INIS)

    Full text: Chile, in general, and Santiago, its capital city, in particular, has serious air pollution problems mainly in winter time when the pollutants could reach dangerous levels which might be detrimental to older people and children. A project was undertaken within the framework of a Co-ordinated Research Programme (CRP) supported by the International Atomic Energy Agency (IAEA) to carry out a long term study on atmospheric air pollution in Chile using biomonitors. The present paper describes the activities carried out within this CRP. The lichens, collected in clean areas (native forests), were transplanted to selected sites in Santiago and exposed during three and six months. At a second stage, samples of Tillandsia recurvata were collected in the Metropolitan Area. All samples were carefully cleaned, using only clean plastic materials, milled at liquid nitrogen temperature, freeze dried, re-homogenized and stored at low temperature until analysis. The samples were mainly analysed by INAA, RNAA SS-AAS and ASV. As part of the routine QA/QC programme, analytical laboratories involved in the project participated in intercomparison runs organized by the IAEA for the determination of trace and minor elements in two lichens samples. From the data and its subsequent mapping over the area under study, it was possible to identify places exposed to higher amounts of some elements. Of interest are also the correlations between several elements, perhaps indicating a given source of pollutants. The results indicate the usefulness of biomonitoring air pollution using lichens and Tillandsias, which, jointly with multielemental analytical techniques, such as NAA, open the possibility to study extensive areas without the infrastructure needed for conventional APM sample collection and at reduced costs.

  11. Chile ushers in new hydro era

    International Nuclear Information System (INIS)

    The planned construction of two hydroelectric power plants at Peuchen and Mampil, will help to meet Chile's growing electricity demand. Securing finance for the project has been straight forward thanks to the optimal hydrological conditions, rivers with a very strong flow providing a large head of water over short distance. Hydropower plays a central role in Chile's generating capacity providing 70% of total energy consumption. Thus, the future of these projects will be highly successful, it is argued. (UK)

    Despite success in reducing poverty over the last twenty years, inequality in Chile has remained virtually unchanged, making Chile one of the least equal countries in the world. High levels of inequality have been shown to hamper further reductions in poverty as well as economic growth and local inequality has been shown to affect such outcomes as violence and health. The study of inequality at the local level is thus crucial for understanding the economic well-being of a country. Local measu...

  19. Salmonella Radicidation of Dry Mixed Feeds and Feed Ingredients

    International Nuclear Information System (INIS)

    Feed components contaminated with salmonellae act as vehicles in the transmission of these bacteria to slaughter animals and hence to meat and poultry. Terminal decontamination of ingredients or mixed feed seems required because sanitary improvements in processing, bagging and storage do not always appear effective in considerably reducing salmonella contamination rates. Experiments were carried out to assay the decontamination effect of pelletization of mixed feed. Enumeration of enterobacteriaceae was used as the analytical criterion. It appeared that a temperature over 80°C generally led to five decimal reductions in enterobacteriaceae counts; however, also currently used lower temperatures may bring about two decimal reductions only. Following earlier experiments with fish meal, range finding tests on the decontamination of mixed feed with 60Co gamma rays were also performed. To achieve five decimal reductions in the counts of the most resistant enterobacteriaceae which were encountered about 0.5 Mrad was required; survival curves were generally not linear, so that overall effective dose had to be used as a parameter. Feeding experiments with rats, using 35% fish meal irradiated at 0.8 Mrad in the diet for two years, demonstrated that neither losses of nutritive value nor the occurrence of orally toxic factors is effected by such an irradiation treatment. It is recommended that pilot plant tests be carried out. In these tests an attempt should be made to combine improved sanitation and pelletizing with a terminal radiation treatment of the bagged material with the lowest dose required. Such tests should preferably be carried out in suitable areas of countries like Peru or Chile. A brief outline is given of the development work and training of scientific and technical staff that should be carried out during the installation of such a pilot plant. (author)

    Full Text Available En este artículo se analiza un conjunto de manifestaciones indicativas del resurgimiento de la huelga obrera en Chile, con especial atención en el marco de las condiciones políticas en que evolucionaron las organizaciones obreras, desde finales de la dictadura hasta la reciente era neoliberal. Además se examina la reaparición de expresiones reivindicativas de los trabajadores, que se han dado a pesar de algunas medidas dirigidas a despolitizar las luchas laborales y de varias reformas legales que redujeron el espacio de actuación de las organizaciones obreras. Estos variados esfuerzos organizativos han tenido lugar en sectores primarios, en donde se confrontan las nuevas condiciones de flexibilización y precariedad que el empresariado chileno ha impulsado. En contra de las perspectivas estructuralistas, en este análisis se sustenta la importancia que los subcontratistas y los trabajadores tercerizados han tenido en dichos procesos, y la apelación a huelgas extralegales en tanto hechos significativos en relación con la actual crisis de las clásicas identidades ligadas a la vida fabril y al trabajo normal

    Salmonella enterica subspecies enterica serotype Newport is one of the common serotypes causing foodborne salmonellosis outbreaks in the United States. Salmonella Newport consists of three lineages exhibiting extensive genetic diversity. Due to the importance of Salmonella pathogenicity islands 5 and 6 (SPI-5 and SPI-6) in virulence of pathogenic Salmonella, the genetic diversity of these two SPIs may relate to different potentials of Salmonella Newport pathogenicity. Most Salmonella Newport strains from North America belong to Salmonella Newport lineages II and III. A total 28 Salmonella Newport strains of lineages II and III from diverse sources and geographic locations were analyzed, and 11 additional Salmonella genomes were used as outgroup in phylogenetic analyses. SPI-5 was identified in all Salmonella Newport strains and 146 single nucleotide polymorphisms (SNPs) were detected. Thirty-nine lineage-defining SNPs were identified, including 18 nonsynonymous SNPs. Two 40-kb genomic islands (SPI5-GI1 and SPI5-GI2) encoding bacteriophage genes were found between tRNA-ser and pipA. SPI5-GI1 was only present in Salmonella Newport multidrug-resistant strains of lineage II. SPI-6 was found in all strains but three Asian strains in Salmonella Newport lineage II, whereas the three Asian strains carried genomic island SPI6-GI1 at the same locus as SPI-6 in other Salmonella. SPI-6 exhibited 937 SNPs, and phylogenetic analysis demonstrated that clustering of Salmonella Newport isolates was a reflection of their geographic origins. The sequence diversity within SPI-5 and SPI-6 suggests possible recombination events and different virulence potentials of Salmonella Newport. The SNPs could be used as biomarkers during epidemiological investigations. PMID:25188010

    Full Text Available Aim: Procalcitonin (PCT as a diagnostic marker for bacteremia and sepsis has been extensively studied. We aimed to study PCT levels in Salmonella infections whether they would serve as marker for early diagnosis in endemic areas to start empiric treatment while awaiting blood culture report. Materials and Methods: BACTEC blood culture was used to isolate Salmonella in suspected enteric fever patients. Serum PCT levels were estimated before starting treatment. Results: In 60 proven enteric fever patients, median value of serum PCT levels was 0.22 ng/ml, values ranging between 0.05 and 4 ng/ml. 95% of patients had near normal or mild increase (<0.5 ng/ml, only 5% of patients showed elevated levels. Notably, high PCT levels were found only in severe sepsis. Conclusion: PCT levels in Salmonella infections are near normal or minimally increased which differentiates it from other systemic Gram-negative infections. PCT cannot be used as a specific diagnostic marker of typhoid.

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

  5. Isotope hydrology in northern Chile

    International Nuclear Information System (INIS)

    Environmental isotope analyses were done on samples from aquifers in the Pampa del Tamarugal and the Salar de Atacama drainage basin in northern Chile. In the Pampa it is possible to delineate individual groundwater bodies on the basis of their 18O and deuterium contents and, in some cases, to relate these to specific recharge areas. A marked displacement from the meteoric water line indicates that river recharge is an important mechanism for groundwater renewal. Groundwater ages appear high at distance from the Andes and much of the water found in the Pampa may have to be treated as a non-renewable resource. The groundwaters, springs and rivers of the Salar de Atacama drainage basin vary between -6.09 and -8.06%. No difference between the different waters can be recognized and an evaporative isotope enrichment indicates that also here river recharge is an important process. Some groundwaters adjacent to the Salar are very salty but 18O and deuterium data show that these waters are not refluxed brines but simply salty freshwater. The 14C contents in groundwaters and springs are very low but their delta13C values are high. It is concluded that this is probably due to the uptake of volcanic CO2. 14C age dating is thus not possible unless the delta13C values of all possible carbon sources can be defined and the geochemical evolution of the groundwaters is better understood.

  6. Regulated electricity retailing in Chile

    International Nuclear Information System (INIS)

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: → We review Chile's experience with regulated electricity retailing. → Distortions emerge when energy wholesale prices are volatile and prices stabilized. → Regulated retailers gain little by mitigating or correcting distortions. → Sometimes price distortions increase retailers' profits. → We estimate the cost of three distortions, which retailers have not corrected.

  8. Radioactive wastes management development in Chile

    International Nuclear Information System (INIS)

    A Facility for immobilizing and conditioning of radioactive wastes generated in Chile, has recently started in operation. It is a Radioactive Wastes Treatment Plant, RWTP, whose owner is Comision Chilena de Energia Nuclear, CCHEN. A Storgement Building of Conditioned Wastes accomplishes the facility for medium and low level activity wastes. The Project has been carried with participation of chilean professionals at CCHEN and Technical Assistance of International Atomic Energy Agency, IAEA. Processes developed are volume reduction by compaction; immobilization by cementation and conditioning. Equipment has been selected to process radioactive wastes into a 200 liters drum, in which wastes are definitively conditioned, avoiding exposition and contamination risks. The Plant has capacity to treat low and medium activity radioactive wastes produced in Chile due to Reactor Experimental No. 1 operation, and annex Laboratories in Nuclear Research Centers, as also those produced by users of nuclear techniques in Industries, Hospitals, Research Centers and Universities, in the whole country. With the infrastructure developed in Chile, a centralization of Radioactive Wastes Management activities is achieved. A data base system helps to control and register radioactive wastes arising in Chile. Generation of radioactive wastes in Chile, has found solution for the present production and that of near future

    Full Text Available Cuando a fines de 1941 el Padre Alberto Hurtado publicó su libro "¿Es Chile un País Católico?", invitaba especialmente a los jóvenes de la Acción Católica a conocer el país real: ¿cómo era de verdad Chile y su Iglesia? Alberto Hurtado con su mirada de apóstol miró a Chile desde la mirada de Jesús y remeció conciencias e incomodó a muchos con su denuncia de los males que corroían el alma nacional: miseria, injusticias, vicios, salarios miserables, falta de educación del pueblo, viviendas indignas, y junto con esto, la lejanía de los pobres de la Iglesia y la escasez de sacerdotes. Para él había una tarea pendiente que muchos esquivaban: conquistar Chile para Cristo. El libro y la invitación fueron acogidos con gran entusiasmo, por los jóvenes especialmente; pero las cr��ticas arreciaron de parte del clero y laicado conservadores. Para ellos, la visión de Hurtado era peligrosamente amarga y desconocía la labor que la Iglesia, desde la Colonia, hacía en el país formando el "alma de Chile". La polémica de fondo era una sorda crítica a Hurtado, asesor nacional de los jóvenes de la Acción Católica.

    1997-04-01

    The emergence of old and new communicable diseases is becoming an important public health problem in industrialized and developing countries worldwide. Chile experienced, at the end of the seventies and during the eighties, epidemics of several emergent communicable infectious diseases whose relevance as public health problems had steadily decreased in the previous 25 years. The most striking of these epidemics was a severe outbreak of typhoid fever that lasted at least 10 years. The majority of the cases occurred in the urban setting of Santiago. Several investigators suggested, in light of apparently good sanitation statistics, that factors responsible for this outbreak of typhoid were an increase in the number of chronic carriers of Salmonella typhi, the lack of microbiological food controls and the consumption of vegetables irrigated with waste water contaminated with S typhi. However, there is a dearth of epidemiological information and field work confirming the role of these factors in this typhoid outbreak. Moreover, the sudden, massive and urban characteristics of this epidemic, coupled to contemporary information regarding shortcomings on the preparation of drinking water and on decreased availability of drinking water to the population in Santiago regardless of good sanitation statistics, suggest that this outbreak may have been partially waterborne. The beginning of this typhoid outbreak also coincided with increased rain fall, with rapidly deteriorating economic and social conditions manifested in high rates of unemployment, and with decreased government investment on social services, including sanitation and health. All these factors are known to influence the epidemiology of typhoid and other emergent diseases worldwide. PMID:9460291

    2015-01-01

    Full Text Available Salmonella enterica species is a Gram negative bacterium, which is responsible for a wide range of food- and water-borne diseases in both humans and animals, thereby posing a major threat to public health. Recently, there has been an increasing number of reports, linking Salmonella contaminated raw vegetables and fruit with food poisoning. Many studies have shown that an essential feature of the pathogenicity of Salmonella is its capacity to cross a number of barriers requiring invasion of a large variety of cells and that the extent of internalization may be influenced by numerous factors. However, it is poorly understood how Salmonella successfully infects hosts as diversified as animals or plants. The aim of this review is to describe the different stages required for Salmonella interaction with its hosts: (i attachment to host surfaces; (ii entry processes; (iii, multiplication; (iv suppression of host defence mechanisms ; and to point out similarities and differences between animal and plant infections.

Tomando como eje el tema de la equidad, la exposición examina las decisiones tomadas desde mediados de 1920 hasta 1973 para avanzar en dirección a la socialización de la medicina y la abrupta interrupción de ese proceso con el golpe militar de 1973. En seguida, se aborda el conjunto de medidas regresivas tomadas por el neoliberalismo autoritario para insertar la salud en la economía de mercado. Por último, se analizan los esfuerzos emprendidos por los gobiernos democráticos desde que asumieron el poder, en 1990, en el sentido de corregir las desigualdades socio-económicas heredadas, enfocando el compromiso de reconstruir el sistema médico asistencial bajo nuevas bases asentadas en los principios de equidad, solidaridad y participación.This paper examines the main changes in the Chilean health system from the 1920s to the present, identifying contradictions, limits, and successes in terms of policy outcomes. Taking equity as the central theme, the analysis focuses on decisions made from the mid-1920s until 1973 in moving toward socialized medicine, with the sudden interruption of this process by the military coup in 1973. The author then discusses the set of regressive measures taken by authoritarian neoliberalism, with the help of Pinochet, to insert health into the market economy. Finally, the article analyzes efforts made by democratic administrations since 1990 to redress the legacy of socioeconomic inequalities, focusing on the commitment to rebuild the health care system with a new basis in equity, solidarity, and people's participation.

    Full Text Available Basado en los informes diplomáticos chilenos, este artículo analiza el tema de las relaciones entre Chile y Canadá, en el período en que esos países avanzaron hacia el intercambio de embajadas, entre 1941 y 1944. En él se explica que hasta antes de esos años, Canadá solo tenía un interés comercial en América Latina, mientras que para Chile era más importante el plano diplomático, a causa de su interés en reforzar su posición internacional, un tanto debilitada desde comienzos del siglo XX. Las razones que llevaron a ambos países a tomar esa decisión estuvieron directamente relacionadas con el contexto de la Segunda Guerra Mundial. Una vez instaladas las embajadas, se comentan las impresiones que tuvieron los primeros representantes de Chile en Ottawa acerca de lo que era Canadá, lo que muestra las dificultades en comprender el funcionamiento de un país bastante distinto a Chile. El artículo concluye que el establecimiento de embajadas no trajo un incremento significativo a corto plazo en las relaciones entre ambos países, ni a nivel comercial ni políticoBased on the reports of the Chilean foreign mission in Canada, this article deals with the relations between Chile and Canada during the period in which both countries decided to exchange embassies. It explains that before those years, Canada was interested in Latin America mainly in commercial topics, while Chile showed more interest on the diplomatic side. This difference is due to the fact that Chile found itself in a rather vulnerable position before 1939. The Second World War was the main reason that led to the establishment of embassies in both countries. The article analyzes also the first impressions of the Chilean representatives in Ottawa, showing that it was not easy for Chilieans to understand the nature of a country like Canada. It ends saying that in the short term, the establishment of embassies did not lead to an increase in the commercial or the political

    2014-12-01

    Infection control is achieved through all efforts used to prevent the introduction and limit the spread of contagious pathogens within a facility or population, with the goal of eliminating sources of potentially pathogenic microorganisms and to disrupt infectious disease transmission. Congregating animals from multiple sources, as occurs at veterinary hospitals, racetracks, equestrian events, and boarding and training facilities, increases the risk for transmission of infectious diseases such as salmonella. There is a recognizable standard of practice for infection control and due effort must be given to control and prevention of infectious disease transmission within animal populations and facilities.

    Full Text Available Propolis is commercialized in Chile as an antimicrobial agent. It is obtained mainly from central and southern Chile, but is used for the same purposes regardless of its origin. To compare the antimicrobial effect, the total phenolic (TP, the total flavonoid (TF content and the phenolic composition, 19 samples were collected in the main production centers in the Región del Maule, Chile. Samples were extracted with MeOH and assessed for antimicrobial activity against Gram (+ and Gram (− bacteria. TP and TF content, antioxidant activity by the DPPH, FRAP and TEAC methods were also determined. Sample composition was assessed by HPLD-DAD-ESI-MS/MS. Differential compounds in the samples were isolated and characterized. The antimicrobial effect of the samples showed MICs ranging from 31.5 to > 1000 µg/mL. Propolis from the central valley was more effective as antibacterial than those from the coastal area or Andean slopes. The samples considered of interest (MIC ≤ 62.5 µg/mL showed effect on Escherichia coli, Pseudomonas sp., Yersinia enterocolitica and Salmonella enteritidis. Two new diarylheptanoids, a diterpene, the flavonoids pinocembrin and chrysin were isolated and elucidated by spectroscopic and spectrometric means. Some 29 compounds were dereplicated by HPLC-MS and tentatively identified, including nine flavones/flavonol derivatives, one flavanone, eight dihydroflavonols and nine phenyl-propanoids. Propolis from the Región del Maule showed large variation in antimicrobial effect, antioxidant activity and composition. So far the presence of diarylheptanoids in samples from the coastal area of central Chile can be considered as a marker of a new type of propolis.

    Full Text Available El presente artículo estudia la evolución del movimiento de panaderos en Chile, desde fines del siglo XIX hasta 1930. En especial se hace referencia a la etapa de movilizaciones para la eliminación del trabajo nocturno en las panaderías durante 1923 y 1924. Se plantea como tesis central que el movimiento de panaderos estaba en un proceso de transición organizativa desde la modalidad de sociedad de resistencia hacia una organización sindical proclive a institucionalizar sus demandas y aceptar la legislación, aspecto que explica la demanda en pro de la eliminación del trabajo nocturno. El mejoramiento en las condiciones de trabajo supuso modernizar el mercado laboral y generar nuevas modalidades de control de la mano de obra.This article studies the evolution of the bakers' movement in Chile, from the beginning of the nineteenth century to the 1930s. Special reference is made to the demonstrations organized to elimínate night work in the bakeries in 1923 and 1924. The main argument is that the bakers' movement was in a transitional period of organization from a resistance society to a labour-union organization. As a result there was an attempt to institutionalize their demands and accept legislation, which explains their demand in order to elimínate night work. The improvement of working conditions implied the modernization of the labour market and the generation of new forms of labour control.

El presente artículo muestra los resultados asociados a los procesos de significación, que profesores y estudiantes construyeron desde su participación en un proyecto en el que se implementaron diseños didácticos colaborativos con uso de TIC, en particular de redes sociales. Se efectuaron grupos focales con 102 estudiantes y entrevistas en profundidad a 21 profesores, en dos momentos (pre y post, quienes participaron de 21 experiencias didácticas ejecutadas en 12 colegios en el sur austral de Chile. Los principales resultados revelan que existe una alta valoración de la experiencia vinculada principalmente a los efectos motivadores que provocan las tecnologías y redes sociales en los estudiantes, el cambio en la interacción didáctica al interior de las aulas, el interés ante la posibilidad de colaborar con estudiantes de otros contextos escolares geográficamente distantes, el desconocimiento, por parte de profesores, de los recursos de la Web 2.0 y aprensiones ante el uso indebido de los recursos que provee Internet. En conclusión, la investigación permitió levantar desde los procesos de significación de sus protagonistas, información cualitativa relevante en torno a las implicancias didácticas, tecnológicas y logísticas de la ejecución de experiencias de aprendizaje colaborativo mediadas por una plataforma virtual de aprendizaje.

    Salmonella is a complex bacterial group with more than 2400 serovars widely distributed in nature; they are considered zoonotic because they can infect a variety of animals and be transmitted to humans. Usually, they cause alimentary acquired diseases such as gastroenteritis, typhoid fever, and others that can lead to severe complications and death. Serotyping is useful to differentiate among Salmonella, because it shows an important correlation with their clinical and epidemiological patterns; consequently, it is of high value for public health, animal health, agriculture, and industry. To characterize all known Kauffmann-White Salmonella serovars, over 250 antisera are required. Due to this and to high prices antisera, many laboratories worldwide have limitations in establishing Salmonella surveillance. Therefore, we developed and validated a Salmonella flagella microagglutination test (SALMATcor) that significantly reduces laboratory requirements of antisera. SALMATcor is based on scaling down, by fivefold, the antigen:antiserum volumes actually required for the reference method: flagella standard tube agglutination technique (STAT). Antigen preparation, temperatures, and incubation periods remained as established for STAT. The SALMATcor was validated according to ISO/DIS 16140:1999 protocol, which included 1187 comparisons of flagella determinations conducted by SALMATcor and STAT, on 141 Salmonella isolates of 12 common serotypes and the use of antiserum recommended for STAT. SALMATcor concordance was excellent (Cohen's kappa index 0.9982), obtaining relative accuracy >99.9% and relative specificity >99.9%. Additionally, SALMATcor has been used by CNRB-INCIENSA since 2004 to respond to all 40 Salmonella proficiency testing strains, provided by World Health Organization-Global Salmonella Surveillance Network, obtaining 100% concordance on serovar identification. On the basis of the results achieved with SALMATcor and considering that it also significantly

    Full Text Available This study was carried out to investigate the presence of Salmonella sp in flocks of white laying hens. In different farms, the transport boxes of twelve flocks were inspected at arrival for the presence of Salmonella. Four positive (A, B, L and M and one negative (I flocks were monitored at each four weeks using bacteriological examination of cecal fresh feces up to 52 weeks. Birds were also evaluated at 52 weeks, when 500 eggs were taken randomly, and at 76 weeks, after forced molt. Salmonella enterica serovar Enteritidis and S. enterica rough strain were isolated from the transport boxes of the four positive flocks (flocks A, B, L and M. Salmonella sp was not isolated from the transport boxes or from the feces after 76 weeks-old in flock I. Salmonella sp was isolated in the 1st, 11th, 34th, 42nd and 76th weeks from flock A; in the 1st, 4th, 11th and 76th weeks from flock B; in the first week and in the 17th to 52nd weeks from flock L; and in the 1st and 76th weeks from flock M. S. Enteritidis, S. enterica rough strain and Salmonella enterica serovar Infantis were isolated from the four positive flocks. Besides, Salmonella enterica serovar Javiana was isolated from flocks B and L, and Salmonella enterica serovar Mbandaka was isolated from flock L. Eggs produced by flock A and by flock L were contaminated with S. Enteritidis and S. enterica rough strain. According to these results, Salmonella-infected flocks may produce contaminated eggs.

  14. Salmonella radicidation of poultry carcasses

    International Nuclear Information System (INIS)

    This thesis reports investigations using gamma-radiation to decontaminate poultry carcasses. The application to foods of doses of ionizing radiation sufficient to reduce the number of viable specific non-sporeforming pathogenic microorganisms so that none is detectable in the treated food by any standard method is termed radicidation. The doses used in this study were at such a level that no undesirable or unfavourable side-effects occurred. The effects of these doses were studied on salmonellae and other microorganisms present in, or associated with poultry carcasses and in liquid and on solid culture media as well. Decimal reduction (D10) values were estimated. These represent the dose (kGy) required to achieve a reduction in initial colony count from N0 to 0.1 N0. Together with the estimation of the numbers of Salmonella present per carcass the data were used to predict the effect of an ionizing radiation treatment of poultry. Data on the effect of ionizing radiation on the total microflora of poultry carcasses were also collected. (Auth.)

    Full Text Available Non-typhi Salmonella normally presents as a bacteremia, enterocolitis, and endovascular infection but rarely manifests as pleuropulmonary disease. We present a case of a 66-year-old female with underlying pulmonary pathology, secondary to an extensive smoking history, who presented with a left-sided pleural effusion. The causative agent was identified as being group D Salmonella. Decortication of the lung was performed and the patient was discharged on antibiotics with resolution of her symptoms. This case helps to support the inclusion of Salmonella group D as a possible etiological agent of infection in the differential causes of exudative pleural effusions.

    To examine possible correlations in bovine Salmonella isolates between environmental survival and serovar-associated epidemiological patterns, bovine field isolates of Salmonella serovars Typhimurium and Dublin (two each) were inoculated into bovine faeces slurry and tested monthly by culture for survival during a six-month period of storage at a variable ambient temperature in a disused animal transporter. Low moisture conditions, where the slurry was dried onto wooden dowels, increased detectable survival of a low-level inoculum by up to five months, compared with wet slurry. A more modest increase of survival time was seen with storage of wet slurry under refrigeration at 4°C. Under both dry and wet conditions, the concentration of culturable Salmonella Typhimurium declined at a slower rate than did that of Salmonella Dublin. Salmonella that was naturally contaminating bovine faeces from farms with Salmonella Typhimurium did not show superior survival times compared with Salmonella Typhimurium that had been artificially inoculated into samples. The differing survival characteristics of the two serovars that was observed in environmental faeces may complement their different modes of infection in cattle. Salmonella Dublin, being a bovine host-adapted strain that establishes chronic infection in some animals, may have less need to survive for a prolonged period outside of its host than does Salmonella Typhimurium.

    Full Text Available Background & Objective: Molecular typing is an important tool in surveillance and outbreak investigations of human Salmonella infections. In this study, Subtyping of Salmonella Paratyphi B and C isolates derived from Iranian patients was carried out by RAPD-PCR to assess the extent of genetic diversity of these isolates. Materials & Methods: Fourteen Salmonella isolates including 6 strains of Salmonella paratyphi B and 8 strains of Salmonella paratyphi C were characterized using RAPD-PCR. Two arbitrary primers, namely OPP-16 and P1254 were used for RAPD analysis and the dendrograms were constructed with NTsys 2.0 computer software. Results: Both primers showed high discriminatory power in differentiating of the related strains of Salmonella. The dendrograms constructed based on RAPD-PCR profiles (with both primers involving 14 salmonella strains revealed 4 distinct patterns, indicating that these isolates are genetically heterogeneous. Furthermore, a good correlation was not observed between the serotype and the molecular profiles obtained from RAPD data of the Salmonella isolates. Conclusion: The findings of the present study verify the usefulness of RAPD-PCR in characterizing and comparing strains of Salmonella Paratyphi B and C.

  1. Salmonella bongori provides insights into the evolution of the Salmonellae.

    Directory of Open Access Journals (Sweden)

    Full Text Available The genus Salmonella contains two species, S. bongori and S. enterica. Compared to the well-studied S. enterica there is a marked lack of information regarding the genetic makeup and diversity of S. bongori. S. bongori has been found predominantly associated with cold-blooded animals, but it can infect humans. To define the phylogeny of this species, and compare it to S. enterica, we have sequenced 28 isolates representing most of the known diversity of S. bongori. This cross-species analysis allowed us to confidently differentiate ancestral functions from those acquired following speciation, which include both metabolic and virulence-associated capacities. We show that, although S. bongori inherited a basic set of Salmonella common virulence functions, it has subsequently elaborated on this in a different direction to S. enterica. It is an established feature of S. enterica evolution that the acquisition of the type III secretion systems (T3SS-1 and T3SS-2 has been followed by the sequential acquisition of genes encoding secreted targets, termed effectors proteins. We show that this is also true of S. bongori, which has acquired an array of novel effector proteins (sboA-L. All but two of these effectors have no significant S. enterica homologues and instead are highly similar to those found in enteropathogenic Escherichia coli (EPEC. Remarkably, SboH is found to be a chimeric effector protein, encoded by a fusion of the T3SS-1 effector gene sopA and a gene highly similar to the EPEC effector nleH from enteropathogenic E. coli. We demonstrate that representatives of these new effectors are translocated and that SboH, similarly to NleH, blocks intrinsic apoptotic pathways while being targeted to the mitochondria by the SopA part of the fusion. This work suggests that S. bongori has inherited the ancestral Salmonella virulence gene set, but has adapted by incorporating virulence determinants that resemble those employed by EPEC.

El trabajo discute el hecho de que los discursos feministas, luego de la dictadura (1973-1990, continúan sin cuestionar la categoría "mujeres", que generaliza y suprime las diferencias de clase y raza entre ellas mismas. Tal presupuesto es analizado frente al acuerdo de los gobiernos democráticos chilenos con los intereses de la oligarquía y de la iglesia católica en la manutención del status quo.Parte de este compromiso viene restringiendo los discursos feministas a la estructura familiar nuclear, de forma que temas como clase, raza y sexualidad no alcanzan a ser enteramente problematizadas. En la medida en que las feministas chilenas no están cuestionando su lugar de enunciación, problemas como derecho reproductivo o el acceso de las mujeres al espacio público continúan siendo vistos desde una perspectiva privilegiada, que anula las discriminaciones existentes entre las mujeres.This essay is about the new trends on Chilean feminisms and how they have become part of the social text. The paper discusses how feminist discourses after dictatorship (1973-1990 remain without putting into question the category of "women" as a generalization that erases class and racial differences among women. This is analyzed in the context of the compromise made by Chilean democratic governments with the interests of oligarchy and the Catholic Church in order to maintain the status quo. Part of this compromise has constrained feminist discourses to the nuclear family frame, within which class, race and sexuality cannot be fully problematized. Since Chilean feminists are not questioning their place of enunciation, problems such as reproductive rights or women access to the public space continue to be seen from a privileged perspective that obliterates the existing discriminations among women.

    Full Text Available Chile ha estado libre de de la enfermedad de Newcastle del tipo PMV-1 desde 1977; por consiguiente, el objetivo del presente estudio fue evaluar el riesgo de introducción de la enfermedad de Newcastle asociado a la importación de avestruces. Se utilizó un modelo de simulación de tipo estocástico, para lo cual se consideraron los siguientes procesos: los relacionados previos a la importación en el país de origen, aquellos que corresponden al proceso mismo de importación y los realizados en la cuarentena en el país de destino. De acuerdo a los reportes de enfermedad en cada uno de los países exportadores de avestruces, se categorizó a los países en dos niveles: aquel donde la enfermedad de Newcastle no ha sido reportada y el de un país endémico. Las probabilidades de las entradas del modelo de simulación fueron obtenidas de fuentes bibliográficas e información sanitaria publicada por organismos de sanidad animal. Se ejecutó un análisis de sensibilidad, para lo cual se usó el coeficiente de correlación de rango a fin de identificar las variables que ejercen mayor influencia en el modelo, siendo éstas: la probabilidad de brote y la cantidad de avestruces importadas. Esta información sirvió para el diseño de cuatro escenarios que incluyeron valores extremos de la presentación de la enfermedad basados en la situación endémica, así como el uso de una mejor prueba diagnóstica. El número de avestruces positivos que ingresarían a Chile resultó fuertemente relacionado al número de brotes en el país endémico y al número de avestruces importadas del país endémico; el valor fue de 2.2 x 10-5, con un límite de confianza superior del 90% de 8.5*10-5 por año. El riesgo de introducción de la enfermedad de Newcastle a Chile asociado a la importación de avestruces fue muy bajo, incluso en los peores escenarios.Chile has been free of Newcastle disease (ND of type PMV- 1 since 1977.

    This study evaluated the efficacy of a 915 MHz microwave with 3 different levels to inactivate 3 serovars of Salmonella in peanut butter. Peanut butter inoculated with Salmonella enterica serovar Senftenberg, S. enterica serovar Typhimurium and S. enterica serovar Tennessee were treated with a 915 MHz microwave with 2, 4 and 6 kW and acid and peroxide values and color changes were determined after 5 min of microwave heating. Salmonella populations were reduced with increasing treatment time and treatment power. Six kW 915 MHz microwave treatment for 5 min reduced these three Salmonella serovars by 3.24-4.26 log CFU/g. Four and two kW 915 MHz microwave processing for 5 min reduced these Salmonella serovars by 1.14-1.48 and 0.15-0.42 log CFU/g, respectively. Microwave treatment did not affect acid, peroxide, or color values of peanut butter. These results demonstrate that 915 MHz microwave processing can be used as a control method for reducing Salmonella in peanut butter without producing quality deterioration. PMID:26678129

  9. A carbon nanotube immunosensor for Salmonella

    2011-12-01

    Full Text Available Antibody-functionalized carbon nanotube devices have been suggested for use as bacterial detectors for monitoring of food purity in transit from the farm to the kitchen. Here we report progress towards that goal by demonstrating specific detection of Salmonella in complex nutrient broth solutions using nanotube transistors functionalized with covalently-bound anti-Salmonella antibodies. The small size of the active device region makes them compatible with integration in large-scale arrays. We find that the on-state current of the transistor is sensitive specifically to the Salmonella concentration and saturates at low concentration (<1000 cfu/ml. In contrast, the carrier mobility is affected comparably by Salmonella and other bacteria types, with no sign of saturation even at much larger concentrations (108 cfu/ml.

  10. Radiosensitivity study of salmonella enteritidis in chickens

    International Nuclear Information System (INIS)

    One of the applications of ionizing radiations in food is the inactivation of vegetative phatogenic bacteria (radicidation) such as Salmonella, Shigella, Campylobacter, Vibro and Listeria. These bacteria are associated with the diseases transmitted by food (ETA). Fresh and frozen farmyard fowls can be contaminated with pathogenic microorganisms, between them Salmonella. In Argentine, between years 1987-1990, Salmonella enteritidis was the main cause of salmonellosis. In food irradiation, with the aim of improving and assuring its hygienic quality, it is important to know the radiosensitivity of microorganisms to be inactivated. Inactivation of a determined microorganism shall depend, between others factors, of the species, strain, number and of the irradiation conditions (temperature, media, etc.). D10 value is a very useful data in order to compare radiosensitivities between the microorganisms and the influence of different factors in their sensitivities. In this paper, it was determined the sensitivity to the gamma radiation of Salmonella enteritidis in fresh and frozen chickens

  15. lac repressor is an antivirulence factor of Salmonella enterica: its role in the evolution of virulence in Salmonella.

    Directory of Open Access Journals (Sweden)

    Sandeepa M Eswarappa

    Full Text Available The genus Salmonella includes many pathogens of great medical and veterinary importance. Bacteria belonging to this genus are very closely related to those belonging to the genus Escherichia. lacZYA operon and lacI are present in Escherichia coli, but not in Salmonella enterica. It has been proposed that Salmonella has lost lacZYA operon and lacI during evolution. In this study, we have investigated the physiological and evolutionary significance of the absence of lacI in Salmonella enterica. Using murine model of typhoid fever, we show that the expression of LacI causes a remarkable reduction in the virulence of Salmonella enterica. LacI also suppresses the ability of Salmonella enterica to proliferate inside murine macrophages. Microarray analysis revealed that LacI interferes with the expression of virulence genes of Salmonella pathogenicity island 2. This effect was confirmed by RT-PCR and Western blot analysis. Interestingly, we found that SBG0326 of Salmonella bongori is homologous to lacI of Escherichia coli. Salmonella bongori is the only other species of the genus Salmonella and it lacks the virulence genes of Salmonella pathogenicity island 2. Overall, our results demonstrate that LacI is an antivirulence factor of Salmonella enterica and suggest that absence of lacI has facilitated the acquisition of virulence genes of Salmonella pathogenicity island 2 in Salmonella enterica making it a successful systemic pathogen.

    Salmonella continues to cause a considerable number of foodborne illnesses worldwide. The sources of outbreaks include contaminated meat and produce. The purpose of this study was to establish an initial investigation of the burden of Salmonella in produce and beef from Honduras by sampling retail markets and abattoirs. Retail produce samples (cantaloupes, cilantro, cucumbers, leafy greens, peppers, and tomatoes; n = 573) were purchased in three major cities of Honduras, and retail whole-muscle beef (n = 555) samples were also purchased in four major cities. Additionally, both hide and beef carcass (n = 141) samples were collected from two Honduran abattoirs. Whole-muscle beef samples were obtained using a sponge hydrated with buffered peptone water, and 10 ml of the buffered peptone water rinsate of each produce sample was collected with a dry sponge and placed in a bag to be transported back to the United States. Salmonella was detected using a commercially available, closeplatform PCR system, and positive samples were subjected to culture on selective media to obtain isolates. Overall, the prevalence of Salmonella-positive samples, based on PCR detection in Honduras (n = 555) retail beef was 10.1% (95% confidence interval = 7.8, 12.9), whereas 7.8% (n = 141) of beef carcass and hides samples were positive in both beef plants. The overall Salmonella prevalence for all produce samples (n = 573) collected was 2.1% (95% confidence interval = 1.2, 3.6). The most common serotypes identified in Honduras were Salmonella Typhimurium followed by Derby. These results provide an indication of Salmonella contamination of beef and produce in Honduras. Developing a Salmonella baseline for Latin America through an initial investigation like the one presented here contributes to a broader global understanding of the potential exposure through food, thus providing insight into the needs for control strategies.

    Author Summary Critical to the onset of Salmonella infection is the ability of bacteria to force their own entry (‘invade’) into intestinal cells of their mammalian host from where they replicate, spread and cause damage. To achieve this invasion, Salmonella deliver a cocktail of proteins directly into host target cells. These proteins override host cell communications and remodel cell structure, tricking the normally dormant cells into engulfing the invaders. Although we are beginning to und...

Al respecto puede observarse que la discusión se ha desenvuelto en dos planos. Desde una perspectiva subjetiva, se cuestiona la moralidad de la deci- sión de interrumpir un embarazo. Desde una perspectiva objetiva, cuál es la legislación y política pública más adecuada para regular el aborto inducido. En este trabajo se abordan las principales cuestiones que surgen en una y otra dimensión. Así, nos preguntamos: ¿Desde cuándo existe el nasciturus ?; ¿Cuál es el status moral y jurídico del mismo?; ¿Existe un derecho al aborto?; ¿Despenalización del aborto?; ¿En qué circunstancias?; ¿Qué voluntades se requiere para recurrir a él? Concluimos con una propuesta bioética sobre cómo encarar el asunto en nuestro país.

  5. Conditioning of radium sources in Chile

    International Nuclear Information System (INIS)

    A process experimented in Chile to conditioning Ra-226 sources arising as waste from medical uses in Chile is described. The IAEA offered to participate in the Project for Conditioning Radium Sources in order to place all the radium sources in the country under an internationally accepted standard. These sources hare those that have been used in medical applications for many years. The CCHEN made its own modifications to the project's execution by using its own infrastructure and scientific and technical skill in this field. For this purpose, the CCHEN uses the human resources and facilities of the Radioactive Waste Management Unit (UGDR) and acquires materials that are commercially available in the country. IAEA assistance focused on quality assurance, so they supply all expensive items which the UGDR, cannot access, plus they certify the quality of the conditioned products. This assistance is achieved through the approval of procedures and methodologies based on those that are recommended

    International Nuclear Information System (INIS)

    The thermoluminescence properties of the inorganic dust extracted from the Chile Guajillo (paprika) Mexicano, were studied in order to verify the possibility of using the TL technique to discriminate between irradiated and non irradiated peppers. The inorganic dust was found to consist of quartz 60%, albite (NaAlSi3O8) 30%, and ortose (KAlSi3O8) 10%. Its thermoluminescence dose response covers the wide dose range of 1Gy-10kGy, which was attributed mainly to feldspars. Its high sensitivity and its stability over 10 irradiation-readout cycles allow the application of a single grain-single aliquot regeneration dosimetry in Chile Guajillo (paprika). Evaluations based on trapping parameters show that thermal fading at room temperature for glow-peaks above 180 deg.. C, is not a problem in the dosimetry of paprika

    This paper identifies Chile's economic weaknesses and offers policy recommendations for increasing stability. Current problems include weak international financial links, a Central Bank mandate that is ill-designed to deal with terms of trade shocks, a propensity to waste scarce liquidity in the banking system; and limited development of financial markets. The paper's policy recommendations include improving external financial links, molding terms of trade contingencies into anti-cyclical pol...

  3. Radiological protection in interventional cardiology in Chile

    International Nuclear Information System (INIS)

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

    2013-12-01

    Members of Salmonella enterica are important foodborne pathogens of significant public health concern worldwide. This study aimed to determine a range of virulence genes among typhoidal (S. typhi) and non-typhoidal (S. enteritidis) strains isolated from different geographical regions and different years. A total of 87 S. typhi and 94 S. enteritidis strains were tested for presence of 22 virulence genes by employing multiplex PCR and the genetic relatedness of these strains was further characterized by REP-PCR. In S. typhi, invA, prgH, sifA, spiC, sopB, iroN, sitC, misL, pipD, cdtB, and orfL were present in all the strains, while sopE, agfC, agfA, sefC, mgtC, and sefD were present in 98.8, 97.7, 90.8, 87.4, 87.4 and 17.2 %, of the strains, respectively. No lpfA, lpfC, pefA, spvB, or spvC was detected. Meanwhile, in S. enteritidis, 15 genes, agfA, agfC, invA, lpfA, lpfC, sefD, prgH, spiC, sopB, sopE, iroN, sitC, misL, pipD, and orfL were found in all S. enteritidis strains 100 %, followed by sifA and spvC 98.9 %, pefA, spvB and mgtC 97.8 %, and sefC 90.4 %. cdtB was absent from all S. enteritidis strains tested. REP-PCR subtyped S. typhi strains into 18 REP-types and concurred with the virulotyping results in grouping the strains, while in S. enteritidis, REP-PCR subtyped the strains into eight profiles and they were poorly distinguishable between human and animal origins. The study showed that S. typhi and S. enteritidis contain a range of virulence factors associated with pathogenesis. Virulotyping is a rapid screening method to identify and profile virulence genes in Salmonella strains, and improve an understanding of potential risk for human and animal infections. PMID:24426144

    Smith, J L; Huhtanen, C N; Kissinger, J C; Palumbo, S A

    1975-11-01

    Survival of salmonellae in artificially contaminated beef-pork mixtures (approximately 10(4) salmonellae/g) was studied in pepperoni prepared by either a natural flora or lactic starter culture fermentation or in nonfermented sausages. The pepperoni did not become salmonellae free during the usual commercial 15 to 30-day drying period. Salmonella dublin was present in all products, fermented or unfermented, after 42 to 43 days of drying. At a lower level of contamination, 10(3)/g, S. dublin could not be recovered from starter culture-fermented pepperoni after 14 days of drying but persisted in the natural flora-fermented sausage. S. typhimurium (initial count, 10(4)/g) was absent after 42 days of drying when starter culture was used to ferment the pepperoni, but was still present in the natural flora-fermented and unfermented products. S. dublin, host adapted to cattle, or S. choleraesuis, host adapted to swine, had similar survival patterns in beef pork, or beef-pork pepperoni. Heating salmonellae contaminated beef-pork pepperoni (after fermantation but before drying) to an internal temperature of 60 C (trichinae inactivating) eliminated the food-borne pathogen from the sausage product.

    2015-02-01

    Full Text Available Salmonella contamination of eggs and egg shells has been identified as a public health concern worldwide. A recent shift in consumer preferences has impacted on the egg industry, with a push for cage-free egg production methods. There has also been an increased desire from consumers for raw and unprocessed foods, potentially increasing the risk of salmonellosis. In response to these changes, this review explores the current literature regarding Salmonella contamination of eggs during the production processing through to food handling protocols. The contamination of eggs with Salmonella during the production process is a complex issue, influenced by many variables including flock size, flock age, stress, feed, vaccination, and cleaning routines. Currently there is no consensus regarding the impact of caged, barn and free range egg production has on Salmonella contamination of eggs. The literature regarding the management and control strategies post-collection, during storage, transport and food handling is also reviewed. Pasteurisation and irradiation were identified as the only certain methods for controlling Salmonella and are essential for the protection of high risk groups, whereas control of temperature and pH were identified as potential control methods to minimise the risk for foods containing raw eggs; however, further research is required to provide more detailed control protocols and education programs to reduce the risk of salmonellosis from egg consumption.

    Salmonella vertebral osteomyelitis is an uncommon complication of Salmonella infection. We report a case of a 57-year-old transgender male who presented with lower back pain for a period of one month following a fall. Physical examination only revealed tenderness over the lower back with no neurological deficits. MRI of the thoracic and lumbar spine revealed a spondylodiscitis at T10-T11 and T12-L1 and right posterior epidural collection at the T9-T10 level. He underwent decompression laminectomy with segmental instrumentation and fusion of T8 to L3 vertebrae. Intraoperatively, he was found to have acute-on-chronic osteomyelitis in T10 and T11, epidural abscess, and discitis in T12-L1. Tissue and wound culture grew Salmonella Typhi and with antibiotics susceptibility guidance he was treated with intravenous ceftriaxone for a period of six weeks. He recovered well with no neurological deficits. PMID:27034871

    Cloacal swabs were collected from 280 captive psittacine birds belonging to 13 species. Samples of dna were tested by PCR using a pair of primers that amplify a 284 base pair fragment of the Salmonella genus invA gene, and the PCR-positive samples were tested by standard microbiological techniques. Thirteen per cent of the samples were positive by PCR, but negative by microbiological techniques. The infection rates were significantly different among the 13 species, the most commonly infected being Amazona amazonica (28 per cent) and Amazona pretrei (20 per cent). Specific tests for Salmonella Typhimurium Salmonella Enteritidis, Salmonella Pullorum and Salmonella Gallinarum did not produce positive results. PMID:18567929

    Salmonella septic arthritis in healthy, immunocompetent patients is extremely rare. We present the case of a 70-year-old man who presented with a one-day history of painful swelling of his ankle from which was aspirated pus which subsequently grew Salmonella enteritidis. There was no history of trauma or symptoms consistent with Salmonella enterocolitis. Our patient recovered fully after two weeks on intravenous ceftriaxone and six weeks on oral ciprofloxacin. Salmonella is a notifiable disease in the European Union and the United States of America, and is associated with outbreaks as a result of food contamination. The nature of Salmonella arthritis and its appropriate management are outlined.

Se utilizan los datos de prospecciones en terreno por el período entre 1975 a 2002 para estimar el tamaño, la estructura espacial y la tendencia de la población. Un análisis de la población en 1997 arrojó un mínimo de 60 huemules en 12 sitios, y una declinación de un 58% en la población durante un período de dos décadas. Prospecciones recientes entre 1998-2002 indican que la población de huemules ha continuado disminuyendo a 40 individuos en 11 sitios, lo que representa un descenso adicional de un 33%. Desde el año 1987, los huemules han desaparecido de 5, y posiblemente 8, sitios de hábitat primario. Solamente un sitio, el del Río Niblinto que es protegido, muestra un grupo del huemul más o menos estable. Las amenazas al huemul y a su hábitat, tal como los impactos del ganado doméstico, la urbanización, el desarrollo recreativo, la presencia de perros domésticos y las actividades industriales siguen sin disminución en la gran mayoría de los 26 sitios de hábitat primario necesario para la recuperación del huemul. Los datos actuales muestran claramente que una compaña de conservación más amplia es necesaria para resguardar y recuperar la especie en Chile central. Se requieren proteger los sitios de hábitat primario y los corredores conectantes de hábitat del huemul. Para realizar tal objetivo, se necesitan un fuerte compromiso e inversión financiera del gobierno y del sector privado. La creación de un nuevo parque nacional o gran reserva para el huemul y la biodiversidad en el sector de Los Nevados de Chillán, con beneficios relacionados al turismo, la educación pública, e investigaciones científicas, podría ayudar a atraer los recursos financieros que se necesitan para un programa exitoso de conservaciónABSTRACT The only surviving population of huemul in central

    Full Text Available Background and Objective: Salmonellosis is the most common type of food poisoning in developed and developing countries that is caused by Salmonella serotype. Hence, we aimed to identify the Salmonella serovars in eggs obtained from Kohgiluyeh and Boyerahmad province and to evaluate antibiotic resistance of the isolated strains. Material and Methods: In this study, 210 eggs were collected from Kohgiluyeh and Boyerahmad Province. The bacteria were isolated and identified using biochemical tests. After extraction of genomic DNA, Salmonella gender, Salmonella enteritidis and Salmonella typhimurium were investigated by invA, fliC and sefA primers, respectively, using Multiplex PCR method. Results: Of 210, 14 (6.66% were contaminated with Salmonella. Of these, 12 (5.71% were Salmonella typhimurium and 2 (0.95% were related to Salmonella spp. None of the samples were contaminated with Salmonella enteritidis. The highest resistance was related to penicillin (100% and neomycin (78.57%. Conclusion: Salmonella typhimurium is the predominant serovar causing contamination in the eggs of this Province. Given the wide spread of antibiotic resistance in different serotypes of Salmonella, we recommend avoiding of indiscriminate use of antibiotics in livestock and poultry

  16. Rapid radiometric method for detection of Salmonella in foods

    International Nuclear Information System (INIS)

    A radiometric method for the detection of Salmonella in foods has been developed which is based on Salmonella poly H agglutinating serum preventing Salmonella from producing 14CO2 from [14C] dulcitol. The method will detect the presence or absence of Salmonella in a product within 30 h compared to 4 to 5 days by routine culture methods. The method has been evaluated against a routine culture method using 58 samples of food. The overall agreement was 91%. Five samples negative for Salmonella by the routine method were positive by the radiometric method. These may have been false positives. However, the routine method may have failed to detect Salmonella due to the presence of large numbers of lactose-fermenting bacteria which hindered isolation of Salmonella colonies on the selective agar plates

    Full Text Available Shrimp is an important non-oil commodity for foreign trade in Indonesia. However, rejection of shrimp exports by the importing countries is still commonly encountered. In 2011, the USFDA recorded two cases of Salmonella spp. contamination in shrimp products from two shrimp processing companies in Indonesia. Analysis of Salmonella spp. in seafood is generally performed using a conventional method which takes at least 5 days. The objective of the study is to get a Salmonellae rapid detection method in shrimp by PCR. In this study, optimization of PCR protocol method to detect Salmonella invA gene was conducted using six different annealing temperatures (59, 59.5, 60.8, 62, 64 and 64.5°C. The results showed that 64°C was the optimum annealing temperature to detect the 284 bp fragment of Salmonella invA gene. The PCR based detection method has a DNA detection limit of 27.81ug/mL and 10°CFU/mL of viable salmonellae with 100% specificity. The PCR protocol is capable of detecting six different Salmonella serovars (S. Enteritidis, S. Hadar, S. Heidelberg, S. Kentucky, S. Paratyphi and S. Typhimurium but none of the non salmonellae isolates. Application of the PCR assay on Salmonella in shrimp after the selective enrichment step suggested that all 16 samples were positive for Salmonella. At the same time, the conventional method could only detected 3 samples for Salmonella positive.

La frontera sur araucana reunió intereses, potencialidades y capitales que le permitieron desarrollarse fuera del marco tradicional del Chile central; instituciones y personas naturales se sorprendían y maravillaban al momento de presenciar la complejidad y racionalidad del modelo fabril erigido por los germano-descendientes en la frontera sur de Chile. Para contemporáneos e historiadores, la abrupta crisis y desaparición del experimento puede ser reducida a un factor, la entrada del Estado chileno a la región. Sin méritos de desestimar tal hipótesis, nos hemos de centrar en el estudio de la crisis desde el ámbito laboral, aquello nos permitiría relocalizar su estudio desde los factores externos, a las condiciones, y condicionantes, internos de la fábrica. Posibilitándonos insertar al trabajador en un mercado de consumo en expansión que colisionaba con las políticas laborales y salariales utilizadas por tales manufacturas.

    Full Text Available Se estudia la evolución de la actividad acuícola en Chile y el impacto de los cambios regulatorios sobre las decisiones de localización de los centros de cultivo. Este estudio considera un análisis descriptivo del desarrollo espacio-temporal de los centros de cultivo. Luego, utilizando un panel de datos, se estimó un modelo de elección de sitios con el objetivo de explorar los factores determinantes de la elección de ubicación de los centros acuícolas. Los resultados del análisis sugieren la existencia de un claro patrón de desarrollo espacio-temporal de la acuicultura en Chile. Este patrón está caracterizado por el desplazamiento de la actividad productiva hacia el sur de la Patagonia chilena cambiando su concentración desde los alrededores de Puerto Montt hacia el sur de la isla de Chiloé. La estimación del modelo de elección de sitios sugiere que la distancia entre los centros y la existencia de centros de la misma especie cultivada son relevantes para explicar el fenómeno de expansión de la acuicultura hacia el sur. Los cambios regulatorios parecen ser un factor que ha influido en el desarrollo del patrón espacio-temporal que caracteriza el uso del territorio por parte de la industria acuícola nacional.

En base al seguimiento y análisis de noticias sobre la prueba PISA desplegadas en diarios electrónicos en Chile y Argentina, más la revisión de fuentes secundarias, se exponen algunas de las controversias suscitadas en torno a la evaluación y se discute sobre su posible impacto en nuestras percepciones sobre educación y calidad. También se problematiza el carácter neutral y objetivo de la prueba, y se levanta la pregunta acerca de su posible agencia en la cristalización de las relaciones de centro-periferia entre países que, en el marco del enfoque de la TAR, tiene sentido explorar.

Detectar la presencia de anticuerpos séricos sanguíneos contra los virus de la Enfermedad de Newcastle (ENC e Influenza aviar (IA, para comprender la contribución de las aves silvestres en la transmisión de estos virus en Chile. Materiales y métodos. Se analizaron 63 aves pertenecientes a los órdenes Falconiformes y Strigiformes desde centros de rehabilitación de aves de las zonas central y sur de Chile. Se realizaron las pruebas de inhibición de la hemoaglutinación (IHA para detectar anticuerpos contra el virus ENC e inmunodifusión en gel agar (IDGA y ELISA para IA. Resultados. Se detectaron 14 aves positivas (22.2% para anticuerpos séricos contra el virus de la ENC. En cambio, no se registraron anticuerpos séricos sanguíneos para el virus de la IA. Conclusiones. La presencia de aves rapaces positivas en los centros de rescate a los anticuerpos séricos contra el virus de la ENC puede ser explicada por el consumo de carne de pollos que han sido vacunados contra ENC o consumo de aves que han adquirido directamente el virus vacunal a través de los distintos procedimientos de administración (aerosoles, bebederos de la vacuna o por el ingreso a los centros de rescate de aves rapaces migratorias, las que podrían facilitar la diseminación de la infección desde los países de origen, hecho que debe ser investigado.

  15. Forest mapping with satellite in Chile

    Persson, A. [SSC Satellitbild (Sweden)

    1995-12-31

    Chile has about 9.1 million ha of forest land, among which 7.6 million ha are native forest and 1.5 million ha are plantations of exotic species. The number of plantations is constantly growing due to the important role these areas play in the national economy. Pino Radiata (Pinus radiata) is found in most of the plantations while the remaining parts are dominated by Eucalyptus (Eucalyptus spp.) The governmental Instituto Forestal (INFOR) in Santiago de Chile, is monitoring the rapid changes in these areas through frequent inventories. As an inventory of this type takes about six years to complete in all areas (one region per year), it is of great importance to find quicker ways to cover these areas. The native forest has in recent years been the subject of debate, not only for economic reasons, but also as a result of ecological pressure for conservation. Where to conserve, where to put restrictions and where to allow forestry are the big issues. Against this background it is necessary to evaluate different data sources that can give information about the present forest situation and provide the means to monitor the changes. The aim of the project was to evaluate whether satellite imagery could fulfill INFOR`s demand for forestry information, and to investigate the kind of data source and methodology to apply when using satellite data

  16. The ecology of Chagas disease in Chile.

    Schofield, C J; Apt, W; Miles, M A

    1982-01-01

    Chagas disease probably affects over half a million people in Chile, principally in rural communities in the fertile valleys of the arid 'norte chico' region, north of Santiago. The main domestic vector is Triatoma infestans, but Triatoma spinolai, although mainly in rocky sylvatic and peridomestic ecotopes, also invades houses. Since the Spanish invasion in the sixteenth century, and particularly during the last 100 years, the endemic region has suffered an ecological breakdown, largely due to excessive timbering and over-grazing, which has led to a denuded landscape with severe loss of agricultural productivity. This breakdown, combined with uneconomically sized farms and poor marketing, exacerbates the poverty of the rural communities. As in other similar areas of Latin America, the combination of poverty and poor education discourages improvements in housing which would reduce the risk of vector-transmitted Chagas disease. This paper reviews the historical and ecological background of the endemic region of Chile, both as a basis for further work, and as a point of comparison with other endemic areas. The review attempts to show how the current status of Chagas disease is likely to be maintained through its association with poor quality housing, poverty and ecological degradation, drawing parallels with other endemic++ areas and suggesting ways by which the ecological damage might be reversed.

    Full Text Available Archeological evidence suggest that the cultural developments occurred in the highlands around lake Titicaca in the Central Andes, exerted influence on the cultural elaborations of the human groups that peopled the valley of Azapa, close to the city of Arica, and the Pacific coast of northern Chile. In this communication we show by means of a distance analysis, that a craniofacial differentiation accompanied the process of cultural evolution in the valley. The biological influence of Tiwanaku is partially reflected in craniofacial morphology, providing preliminary evidence that cultural changes were associated to intermittent gene flow from the highlands, specially during the Alto Ramírez and San Miguel phasesLos desarrollos culturales ocurridos en el altiplano en el área circumtiticaca en los Andes centrales, ejercieron influencia sobre las elaboraciones culturales de los grupos humanos que poblaban el Valle de Azapa cercano a la ciudad de Arica y la costa del norte de Chile.

  13. Employment of Salmonella in Cancer Gene Therapy.

    Lee, Che-Hsin

    2016-01-01

    One of the primary limitations of cancer gene therapy is lack of selectivity of the therapeutic gene to tumor cells. Current efforts are focused on discovering and developing tumor-targeting vectors that selectively target only cancer cells but spare normal cells to improve the therapeutic index. The use of preferentially tumor-targeting bacteria as vectors is one of the innovative approaches for the treatment of cancer. This is based on the observation that some obligate or facultative-anaerobic bacteria are capable of multiplying selectively in tumors and inhibiting their growth. In this study, we exploited attenuated Salmonella as a tumoricidal agent and a vector to deliver genes for tumor-targeted gene therapy. Attenuated Salmonella, carrying a eukaryotic expression plasmid encoding an anti-angiogenic gene, was used to evaluate its' ability for tumor targeting and gene delivery in murine tumor models. We also investigated the use of a polymer to modify or shield Salmonella from the pre-existing immune response in the host in order to improve gene delivery to the tumor. These results suggest that tumor-targeted gene therapy using Salmonella carrying a therapeutic gene, which exerts tumoricidal and anti-angiogenic activities, represents a promising strategy for the treatment of tumors.

    Bringing together more than 170 years of data, this study represents the first attempt to construct a species checklist and analyze the diversity and distribution of testate amoebae in Chile, a country that encompasses the southwestern region of South America, countless islands and part of the Antarctic. In Chile, known diversity includes 416 testate amoeba taxa (64 genera, 352 infrageneric taxa), 24 of which are here reported for the first time. Species-accumulation plots show that in Chile, the number of testate amoeba species reported has been continually increasing since the mid-19th century without leveling off. Testate amoebae have been recorded in 37 different habitats, though they are more diverse in peatlands and rainforest soils. Only 11% of species are widespread in continental Chile, while the remaining 89% of the species exhibit medium or short latitudinal distribution ranges. Also, species composition of insular Chile and the Chilean Antarctic territory is a depauperated subset of that found in continental Chile. Nearly, the 10% of the species reported here are endemic to Chile and many of them are distributed only within the so-called Chilean biodiversity hotspot (ca. 25° S-47° S). These findings are here thoroughly discussed in a biogeographical and evolutionary context. PMID:26340665

    2007-08-01

    Full Text Available Abstract Background Salmonella paratyphi C, like S. typhi, is adapted to humans and causes typhoid fever. Previously we reported different genome structures between two strains of S. paratyphi C, which suggests that S. paratyphi C might have a plastic genome (large DNA segments being organized in different orders or orientations on the genome. As many but not all host-adapted Salmonella pathogens have large genomic insertions as well as the supposedly resultant genomic rearrangements, bacterial genome plasticity presents an extraordinary evolutionary phenomenon. Events contributing to genomic plasticity, especially large insertions, may be associated with the formation of particular Salmonella pathogens. Results We constructed a high resolution genome map in S. paratyphi C strain RKS4594 and located four insertions totaling 176 kb (including the 90 kb SPI7 and seven deletions totaling 165 kb relative to S. typhimurium LT2. Two rearrangements were revealed, including an inversion of 1602 kb covering the ter region and the translocation of the 43 kb I-CeuI F fragment. The 23 wild type strains analyzed in this study exhibited diverse genome structures, mostly as a result of recombination between rrn genes. In at least two cases, the rearrangements involved recombination between genomic sites other than the rrn genes, possibly homologous genes in prophages. Two strains had a 20 kb deletion between rrlA and rrlB, which is a highly conservative region and no deletion has been reported in this region in any other Salmonella lineages. Conclusion S. paratyphi C has diverse genome structures among different isolates, possibly as a result of large genomic insertions, e.g., SPI7. Although the Salmonella typhoid agents may not be more closely related among them than each of them to other Salmonella lineages, they may have evolved in similar ways, i.e., acquiring typhoid-associated genes followed by genome structure rearrangements.

    Predictive models, to estimate the reduction in Escherichia coli O157:H7 concentration in beef burgers, have been developed to inform risk management decisions; no analogous model exists for Salmonella spp. in pork burgers. In this study, "Extra Lean" and "Regular" fat pork minces were inoculated with Salmonella spp. (Salmonella 4,[5],12,i:-, Salmonella Senftenberg and Salmonella Typhimurium) and formed into pork burger patties. Patties were cooked on an electric skillet (to imitate home cooking) to one of seven internal temperatures (46, 49, 52, 55, 58, 61, 64 °C) and Salmonella enumerated. A generalised linear logistic regression model was used to develop a predictive model for the Salmonella concentration based on the internal endpoint temperature. It was estimated that in pork mince with a fat content of 6.1%, Salmonella survival will be decreased by -0.2407log10 CFU/g for a 1 °C increase in internal endpoint temperature, with a 5-log10 reduction in Salmonella concentration estimated to occur when the geometric centre temperature reaches 63 °C. The fat content influenced the rate of Salmonella inactivation (P=0.043), with Salmonella survival increasing as fat content increased, though this effect became negligible as the temperature approached 62 °C. Fat content increased the time required for patties to achieve a specified internal temperature (P=0.0106 and 0.0309 for linear and quadratic terms respectively), indicating that reduced fat pork mince may reduce the risk of salmonellosis from consumption of pork burgers. Salmonella serovar did not significantly affect the model intercepts (P=0.86) or slopes (P=0.10) of the fitted logistic curve. This predictive model can be applied to estimate the reduction in Salmonella in pork burgers after cooking to a specific endpoint temperature and hence to assess food safety risk. PMID:26686598

  4. Identification of genes to differentiate closely related Salmonella lineages.

    Full Text Available BACKGROUND: Salmonella are important human and animal pathogens. Though highly related, the Salmonella lineages may be strictly adapted to different hosts or cause different diseases, from mild local illness like gastroenteritis to fatal systemic infections like typhoid. Therefore, rapid and accurate identification of Salmonella is essential for timely and correct diagnosis of Salmonella infections. The current identification methods such as 16S rRNA sequencing and multilocus sequence typing are expensive and time consuming. Additionally, these methods often do not have sufficient distinguishing resolution among the Salmonella lineages. METHODOLOGIES/PRINCIPAL FINDINGS: We compared 27 completely sequenced Salmonella genomes to identify possible genomic features that could be used for differentiation of individual lineages. We concatenated 2372 core genes in each of the 27 genomes and constructed a neighbor-joining tree. On the tree, strains of each serotype were clustered tightly together and different serotypes were unambiguously separated with clear genetic distances, demonstrating systematic genomic divergence among the Salmonella lineages. We made detailed comparisons among the 27 genomes and identified distinct sets of genomic differences, including nucleotide variations and genomic islands (GIs, among the Salmonella lineages. Two core genes STM4261 and entF together could unambiguously distinguish all Salmonella lineages compared in this study. Additionally, strains of a lineage have a common set of GIs and closely related lineages have similar sets of GIs. CONCLUSIONS: Salmonella lineages have accumulated distinct sets of mutations and laterally acquired DNA (e.g., GIs in evolution. Two genes entF and STM4261 have diverged sufficiently among the Salmonella lineages to be used for their differentiation. Further investigation of the distinct sets of mutations and GIs will lead to novel insights into genomic evolution of Salmonella and

    Chile's economic performance was very strong during most of the 1990s, but the country suffered a recession in 1998–99. In early 1998, Chile faced a widening external current account deficit—resulting from surging domestic demand and a large drop in copper export prices—which together with turbulence in world financial markets weakened investor confidence and put downward pressure on the currency. Chile has maintained a very open trade regime and has continued with the unilateral phased...

  11. Comparing human-Salmonella with plant-Salmonella protein-protein interaction predictions

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Salmonellosis is the most frequent food-borne disease world-wide and can be transmitted to humans by a variety of routes, especially via animal and plant products. Salmonella bacteria are believed to use not only animal and human but also plant hosts despite their evolutionary distance. This raises the question if Salmonella employs similar mechanisms in infection of these diverse hosts. Given that most of our understanding comes from its interaction with human hosts, we investigate here to what degree knowledge of Salmonella-human interactions can be transferred to the Salmonella-plant system. Reviewed are recent publications on analysis and prediction of Salmonella-host interactomes. Putative protein-protein interactions (PPIs between Salmonella and its human and Arabidopsis hosts were retrieved utilizing purely interolog-based approaches in which predictions were inferred based on available sequence and domain information of known PPIs, and machine learning approaches that integrate a larger set of useful information from different sources. Transfer learning is an especially suitable machine learning technique to predict plant host targets from the knowledge of human host targets. A comparison of the prediction results with transcriptomic data shows a clear overlap between the host proteins predicted to be targeted by PPIs and their gene ontology enrichment in both host species and regulation of gene expression. In particular, the cellular processes Salmonella interferes with in plants and humans are catabolic processes. The details of how these processes are targeted, however, are quite different between the two organisms, as expected based on their evolutionary and habitat differences. Possible implications of this observation on evolution of host-pathogen communication are discussed.

    Free range production systems are becoming a major source of egg production in Australia and worldwide. This study investigated shedding and ecology of Salmonella Typhimurium and Salmonella species in a free range layer flock, wild birds and foxes in the vicinity of the free range farm in different seasons. Shedding of Salmonella was significantly higher in summer. Within the shed, overall, Salmonella prevalence was highest in dust. Corticosterone level in faeces was highest in spring and lowest in winter. There was no direct association between the Salmonella shedding (MPN/gm) and corticosterone levels in faeces. Salmonella Typhimurium MLVA types isolated from fox and wild birds were similar to MLVA types isolated from layer flock and reported during human food borne illness. Wild birds and foxes appear to play an important role in S. Typhimurium ecology and food safety. Environmental factors could play a role in evolution of S. Typhimurium in free range environment.

    Fifteen cases of human pseudoterranovosis are reported for Chile, representing an emerging parasitic infection in this country caused by larvae of the nematode Pseudoterranova sp. Our observations also included an outbreak of pseudoterranovosis in 3 of 4 individuals who shared the same raw fish dish (cebiche). Most of the cases occurred in adult patients. The main source of infection was from consumption raw or fried marine fish, including hakes (Merluccius australis or Merlucciuts gayi), pomfret (Brama australis), Inca scad (Trachurus murphvi), and corvina (Cilus gilberti). Seasonal distribution showed most of the cases to occur in fall and spring. Parasite larvae were isolated from the mouths of most of the patients after they reported a pharyngeal tickling sensation, coughing, vomiting, or a foreign body in the mouth or throat. PMID:17539437

    We have found that prolonged inhibition of bacterial protein synthesis abolishes the ability of Salmonella typhimurium to enter HEp-2 cells. Our results suggest that an essential invasion factor has a functional half-life that is seen as a gradual loss of invasiveness in the absence of protein synthesis. Therefore, Salmonella invasiveness appears to be a transient phenotype that is lost unless protein synthesis is maintained. This finding may explain why salmonellae grown to stationary phase ...

    2007-09-01

    Full Text Available Abstract Background Salmonella enteritidis is suggested to translocate in the small intestine. In vivo it induces gene expression changes in the ileal mucosa and Peyer's patches. Stimulation of Salmonella translocation by dietary prebiotics fermented in colon suggests involvement of the colon as well. However, effects of Salmonella on colonic gene expression in vivo are largely unknown. We aimed to characterize time dependent Salmonella-induced changes of colonic mucosal gene expression in rats using whole genome microarrays. For this, rats were orally infected with Salmonella enteritidis to mimic a foodborne infection and colonic gene expression was determined at days 1, 3 and 6 post-infection (n = 8 rats per time-point. As fructo-oligosaccharides (FOS affect colonic physiology, we analyzed colonic mucosal gene expression of FOS-fed versus cellulose-fed rats infected with Salmonella in a separate experiment. Colonic mucosal samples were isolated at day 2 post-infection. Results Salmonella affected transport (e.g. Chloride channel calcium activated 6, H+/K+ transporting Atp-ase, antimicrobial defense (e.g. Lipopolysaccharide binding protein, Defensin 5 and phospholipase A2, inflammation (e.g. calprotectin, oxidative stress related genes (e.g. Dual oxidase 2 and Glutathione peroxidase 2 and Proteolysis (e.g. Ubiquitin D and Proteosome subunit beta type 9. Furthermore, Salmonella translocation increased serum IFNγ and many interferon-related genes in colonic mucosa. The gene most strongly induced by Salmonella infection was Pancreatitis Associated Protein (Pap, showing >100-fold induction at day 6 after oral infection. Results were confirmed by Q-PCR in individual rats. Stimulation of Salmonella translocation by dietary FOS was accompanied by enhancement of the Salmonella-induced mucosal processes, not by induction of other processes. Conclusion We conclude that the colon is a target tissue for Salmonella, considering the abundant changes in

    Salmonella in cattle herds may behave as epidemic or endemic infections. An intensive longitudinal sampling study across all management groups and ages on six dairy farms in the UK was used to examine patterns of Salmonella shedding, following the prior identification of either Salmonella Dublin (SD) (three farms) or Salmonella Typhimurium (ST) (three farms) on the premises in the context of clinical salmonellosis. Individual faeces, pooled faeces and environmental samples (total 5711 samples), taken approximately every six weeks for 15-24 weeks, were cultured for Salmonella. SD was detected at low frequency (on any visit, 0.5-18.3 per cent of samples positive) and most consistently in calves. By contrast, ST was isolated at higher frequency (on any visit, 6.8-75 per cent of samples positive), and in higher numbers, up to 10(7) cfu/g faeces. Significantly more samples from calves were positive for ST than were positive for SD (50.6 per cent v 3.1 per cent; P < 0.001), which was also true for milking cows (46.3 per cent v 4.4 per cent; P < 0.001). The differences could help to explain the different patterns of bovine infection classically associated with these two serovars in the UK. No consistent effect upon shedding was seen among the ST-infected herds following vaccination. PMID:22859413

  3. Salmonella enterica induces and subverts the plant immune system

    2014-04-04

    Infections with Salmonella enterica belong to the most prominent causes of food poisoning and infected fruits and vegetables represent important vectors for salmonellosis. Although it was shown that plants raise defense responses against Salmonella, these bacteria persist and proliferate in various plant tissues. Recent reports shed light into the molecular interaction between plants and Salmonella, highlighting the defense pathways induced and the means used by the bacteria to escape the plant immune system and accomplish colonization. It was recently shown that plants detect Salmonella pathogen-associated molecular patterns (PAMPs), such as the flagellin peptide flg22, and activate hallmarks of the defense program known as PAMP-triggered immunity (PTI). Interestingly, certain Salmonella strains carry mutations in the flg22 domain triggering PTI, suggesting that a strategy of Salmonella is to escape plant detection by mutating PAMP motifs. Another strategy may rely on the type III secretion system (T3SS) as T3SS mutants were found to induce stronger plant defense responses than wild type bacteria. Although Salmonella effector delivery into plant cells has not been shown, expression of Salmonella effectors in plant tissues shows that these bacteria also possess powerful means to manipulate the plant immune system. Altogether, these data suggest that Salmonella triggers PTI in plants and evolved strategies to avoid or subvert plant immunity. 2014 Garca and Hirt.

    Full Text Available Biodiversity conservation needs to be informed by science. On this regard, scientific efforts ought to be allocated to tackle research priorities; offer sound and explicit advice, and results ought to be translated into conservation plans and programs. If such conditions are met, scientists would be fulfilling their social contract, sensu Lubchenco. In this brief essay I analyze the fulfillment of such a contract in Chile. In general, the scarce priorities set for addressing conservation issues are not considered, only a third of scientific publications in conservation-related issues offer explicit advice and a minor fraction of relevant scientific information is considered in the preparation of conservation plans. Current mismatch between conservation science and practice weakens longstanding efforts to achieve an effective conservation of the Chilean biota. Suggestions are advanced to close the gap.La conservación de la biodiversidad requiere apoyo científico.

El sistema educacional chileno vive un momento de crisis, entendida como oportunidad y cambio en un intento de mejorar la calidad y equidad de ésta. El cuestionamiento del sistema educacional chileno, por parte de la sociedad en su conjunto, se refleja en el debate nacional de los últimos tiempos, lo que ha cambiado la agenda política del gobierno de turno y puesto el tema de la educación en las primeras páginas de los medios de comunicación. El mayor grado de politización del tema, respecto a otras épocas, es principalmente una consecuencia de los movimientos sociales, dada su transversalidad social no partidista, que manifiestan su decepción con el sistema educativo que refleja segmentación social y baja calidad de la enseñanza. Segmentación y calidad son consideradas las verdaderas causas por la cual la educación chilena no es aún el verdadero motivo de desarrollo social. Donde los movimientos, vinculados a la educación, apuntarán a resignificar la educación como el pilar fundamental de la sociedad, como motor de cambio y de proyección del querer ser como país.Abstract: The interest for this paper arises from the current condition of education in Chile.

    The objective of this study was to characterize 365 nontyphoidal Salmonella enterica isolates from animal feed. Among the 365 isolates, 78 serovars were identified. Twenty-four isolates (7.0%) were recovered from three of six medicated feed types. Three of these isolates derived from the medicated feed, Salmonella Newport, Salmonella Typhimurium var. O 5- (Copenhagen), and Salmonella Lexington var. 15+ (Manila), displayed antimicrobial resistance. Susceptibility testing revealed that only 3.0% (12) of the 365 isolates displayed resistance to any of the antimicrobial agents. These 12 isolates were recovered from unmedicated dry beef feed (n = 3), medicated dry beef feed (n = 3), cabbage culls (n = 2), animal protein products (n = 2), dry dairy cattle feed (n = 1), and fish meal (n = 1). Only Salmonella Newport and Salmonella Typhimurium var. O 5- (Copenhagen) were multidrug resistant. Both isolates possessed the IncA/C replicon and the blaCMY-2 gene associated with cephalosporin resistance. Plasmid replicons were amplified from 4 of 12 resistant isolates. Plasmids (40 kb) were Salmonella Montevideo and Salmonella Kentucky. Conjugation experiments were done using 7 of the 12 resistant isolates as donors. Only Salmonella Montevideo, possessing a plasmid and amplifying IncN, produced transconjugants. Transconjugants displayed the same antimicrobial resistance profile as did the donor isolate. Three isolates that amplified replicons corresponding to IncA/C or IncHI2 did not produce transconjugants at 30 or 37°C. The results of this study suggest that the prevalence of antimicrobial-resistant Salmonella contaminating animal feed is low in Texas. However, Salmonella was more prevalent in feed by-products; fish meal had the highest prevalence (84%) followed by animal protein products (48%). Ten of the 35 feed types had no Salmonella contamination. Further investigation is needed to understand the possible role of specific feed types in the dissemination of antimicrobial

  9. Psoralen photomutagenic specificity in Salmonella typhimurium

    International Nuclear Information System (INIS)

    The cytotoxic and mutagenic specificity of two therapeutically employed psoralens was examined in several Ames Salmonella typhimurium strains with near ultraviolet light activation. Photomutagenic activity of 8-methoxypsoralen (8MOP) and 4,5',8-trimethylpsoralen (TMP) was found to be sequence-specific, and additionally was dependent on the level of DNA-repair proficiency. Phototoxicity was essentially identical in hisC3076, hisD3052 and hisG46 strains; uvrB- excision-repair-deficient bacteria were considerably more susceptible to lethal effects than wild-type parental strains. Finally, the data show that psoralens are potent frameshift photomutagens in Salmonella hisC3076 strains and demonstrate the potential utility of these strains in evaluating photomutagenic and phototoxic activity of new furocoumarin derivatives.

    Full Text Available Salmonella typhi is a true pathogen, which is capable of causing both intestinal and extraintestinal infections. Unusual presentations of Salmonella should always be kept in mind as this organism can cause disease in almost any organ of the body. S. typhi has been reported to cause the life-threatening infections such as meningitis, endocarditis, myocarditis, empyema, and hepatic abscess. Renal involvement by S. typhi is a relatively rare presentation. We report a case of renal abscess caused by S. typhi in an afebrile, 10-year-old child who did not have any clinical history of enteric fever. To our knowledge, this is the first reported case of isolation of S. typhi from the renal abscess, and interestingly this isolate was found to be resistant to quinolones.

    Full Text Available Salmonella infection occurs worldwide and is still an important public health problem in many developing countries. The infection can affect almost all major organs including the liver. Severe hepatic involvement with a clinical feature of acute hepatitis is a rare complication. In this paper, a 39-year-old male with acute cholestatic typhoid hepatitis is presented. The case had a tender hepatomegaly and elevated serum alanine and aspartate transaminase, alkaline phosphatase, and gamma glutamyl transferase levels; these features cannot been distinguished from those of acute viral hepatitis. Serological and viral markers of acute viral hepatitis were negative. No pathology could be determined in abdomen Ultrasonography (USG or Magnetic Reso - nance (MR Cholangiography. As enteric fever is a common infection, the recognition of salmonella hepatitis is of clinical importance. When patients from an endemic or outbreak area present acute febrile hepatitis, typhoid fever should be a consideration.

    Salmonella serovars are differentially able to infect chickens. The underlying causes are not yet fully understood. Aim of the present study was to elucidate the importance of Salmonella Pathogenicity Island 1 and 2 (SPI-1 and -2) for the virulence of two non-host-specific, but in-vivo differently invasive, Salmonella serovars in conjunction with the immune reaction of the host. Primary avian splenic macrophages were inoculated with Salmonella enterica sub-species enterica serovar (S.) Typhimurium and S. Infantis. The number and viability of intracellular bacteria and transcription of SPI-1 and -2 genes by the pathogens, as well as transcription of immune-related proteins, surface antigen expression and nitric oxide production by the macrophages, were compared at different times post inoculation. After infection, both of the Salmonella serovars were found inside the primary macrophages. Invasion-associated SPI-1 genes were significantly higher transcribed in S. Infantis- than S. Typhimurium-infected macrophages. The macrophages counteracted the S. Infantis and S. Typhimurium infection with elevated mRNA expression of inducible nitric oxide synthase (iNOS), interleukin (IL)-12, IL-18 and lipopolysaccharide-induced tumor necrosis factor alpha factor (LITAF) as well as with an increased synthesis of nitric oxide. Despite these host cell attacks, S. Typhimurium was better able than S. Infantis to survive within the macrophages and transcribed higher rates of the SPI-2 genes spiC, ssaV, sifA, and sseA. The results showed similar immune reactions of primary macrophages after infection with both of the Salmonella strains. The more rapid and stronger transcription of SPI-2-related genes by intracellular S. Typhimurium compared to S. Infantis might be responsible for its better survival in avian primary macrophages.

    Pathogen detection is a critical point for the identification and the prevention of problems related to food safety. Failures at detecting contaminations in food may cause outbreaks with drastic consequences to public health. In spite of the real need for obtaining analytical results in the shortest time possible, conventional methods may take several days to produce a diagnosis. Salmonella spp. is the major cause of foodborne diseases worldwide and its absence is a requirement of the health authorities. Biosensors are bioelectronic devices, comprising bioreceptor molecules and transducer elements, able to detect analytes (chemical and/or biological species) rapidly and quantitatively. Electrochemical immunosensors use antibody molecules as bioreceptors and an electrochemical transducer. These devices have been widely used for pathogen detection at low cost. There are four main techniques for electrochemical immunosensors: amperometric, impedimetric, conductometric, and potentiometric. Almost all types of immunosensors are applicable to Salmonella detection. This article reviews the developments and the applications of electrochemical immunosensors for Salmonella detection, particularly the advantages of each specific technique. Immunosensors serve as exciting alternatives to conventional methods, allowing "real-time" and multiple analyses that are essential characteristics for pathogen detection and much desired in health and safety control in the food industry.

  6. The fruit fly programme in Chile

    International Nuclear Information System (INIS)

    Full text: country. In fact, no species of the genera Ceratitis, Bactrocera, Anastrepha, Dacus and Toxotrypana exist in the country. This programme uses the Fruit fly National Detection System, which includes detection of the pest by trapping and fruit sampling in different areas located between the I and XI Regions of the country. This system is approved by the Chilean trade partners on the basis of the fruit fly-free recognition. For the Chilean fresh fruit exports, this is an important advantage, because there is no need to apply quarantine treatments or any other restriction measure. Chile has also a huge fruit industry, whose export revenues last season reached USD 1,900 million. This fact has permitted to undertake continuously a big effort to maintain that phytosanitary condition. Since Chile is the only fruit-fly free Latin American country, it has to face a continuous biological pressure of fruit flies, mainly C. capitata, to invade its territory. But the country has also some important advantages to prevent flies migrating due to its natural isolation. These natural barriers are the Los Andes ranges in the east, thousands of kilometers of desert in the north, the Pacific Ocean in the west and finally an extremely cold, sub polar climate in the south. This isolation has led to the NPPO officials to believe that the passive spread, through smuggling and hidden fruit in passenger's baggage, to be the most likely source of fruit fly entries.

The only exception to the mentioned isolation is Arica Province on the border with Peru. There, SAG applies an area-wide preventative approach through the rearing and release of sterile insects, as well as bait spraying in the border area, which is mainly desert, but has some 'green spots' that allow the fly to alight for resting and feeding.

Este relato muestra, a partir de la oralidad de los sujetos, la conexión, disociación y conflicto entre historia de vida e historia nacional - hegemónica, dando cuenta del sitial marginal y pauperizado, que la población mapuche experimenta de manera estructural, desde la pérdida de su territorio y la desarticulación de éste en el siglo XIX en adelante. De este modo, la historia mapuche se articula a partir de los dispositivos de la memoria y su vínculo con la alteridad, desde posiciones marcadas por la colonialidad de las relaciones sociales entre sí y con otros/as. De esta forma, rescatar la memoria histórica de dos  ancianos mapuche, nos adentra en la discusión acerca dela construcción constante de identidad étnica y despliegue de la etnicidad entre los miembros de un grupo determinado, emergiendo de allí discursos culturales, políticos y demandas sociales,que interpelan a la sociedad colonizadora y hegemónica, desde ámbitos tan diversos como laritualidad, el medio ambiente y la relación hombre – naturaleza.

    Members of Salmonella enterica are frequently involved in egg and egg product related human food poisoning outbreaks worldwide. In Australia, Salmonella Typhimurium is frequently involved in egg and egg product related foodborne illness and Salmonella Mbandaka has also been found to be a contaminant of the layer farm environment. The ability possessed by Salmonella Enteritidis to colonize reproductive organs and contaminate developing eggs has been well-described. However, there are few studies investigating this ability for Salmonella Typhimurium. The hypothesis of this study was that the Salmonella Typhimurium can colonize the gut for a prolonged period of time and that horizontal infection through feces is the main route of egg contamination. At 14 weeks of age hens were orally infected with either S. Typhimurium PT 9 or S. Typhimurium PT 9 and Salmonella Mbandaka. Salmonella shedding in feces and eggs was monitored for 15 weeks post-infection. Egg shell surface and internal contents of eggs laid by infected hens were cultured independently for detection of Salmonella spp. The mean Salmonella load in feces ranged from 1.54 to 63.35 and 0.31 to 98.38 most probable number/g (MPN/g) in the S. Typhimurium and S. Typhimurium + S. Mbandaka group, respectively. No correlation was found between mean fecal Salmonella load and frequency of egg shell contamination. Egg shell contamination was higher in S. Typhimurium + S. Mbandaka infected group (7.2% S. Typhimurium, 14.1% S. Mbandaka) compared to birds infected with S. Typhimurium (5.66%) however, co-infection had no significant impact on egg contamination by S. Typhimurium. Throughout the study Salmonella was not recovered from internal contents of eggs laid by hens. Salmonella was isolated from different segments of oviduct of hens from both the groups, however pathology was not observed on microscopic examination. This study investigated Salmonella shedding for up to 15 weeks p.i which is a longer period of time

    Identification of Salmonella serotypes is important for understanding the environmental diversity of the genus Salmonella. This study evaluates the diversity of Salmonella isolates recovered from 165 of 202 Central Florida surface water samples and investigates whether the serotype of the environmental Salmonella isolates can be predicted by a previously published multiplex PCR assay (S. Kim, J. G. Frye, J. Hu, P. J. Fedorka-Cray, R. Gautom, and D. S. Boyle, J. Clin. Microbiol. 44:3608–3615, 2006, http://dx.doi.org/10.1128/JCM.00701-06). Multiplex PCR was performed on 562 Salmonella isolates (as many as 36 isolates per water sample) to predict serotypes. Kauffmann-White serogrouping was used to confirm multiplex PCR pattern groupings before isolates were serotyped, analyzed by pulsed-field gel electrophoresis, and assayed for antimicrobial susceptibility. In 41.2% of the Salmonella-positive water samples, all Salmonella isolates had identical multiplex PCR patterns; in the remaining 58.8%, two or more multiplex PCR patterns were identified. Within each sample, isolates with matching multiplex PCR patterns had matching serogroups. The multiplex patterns of 495 isolates (88.1%) did not match any previously reported pattern. The remaining 68 isolates matched reported patterns but did not match the serotypes for those patterns. The use of the multiplex PCR allowed the number of isolates requiring further analysis to be reduced to 223. Thirty-three Salmonella enterica serotypes were identified; the most frequent included serotypes Muenchen, Rubislaw, Anatum, Gaminara, and IV_50:z4,z23:−. A majority (141/223) of Salmonella isolates clustered into one genotypic group. Salmonella isolates in Central Florida surface waters are serotypically, genotypically, and phenotypically (in terms of antimicrobial susceptibility) diverse. While isolates could be grouped as different or potentially the same using multiplex PCR, the multiplex PCR pattern did not predict the Salmonella

    Peanuts and peanut-based products have been the source of recent Salmonella outbreaks worldwide. Because peanut butter is commonly used as an ingredient in baked goods, such as cookies, the potential risk of Salmonella remaining in these products after baking needs to be assessed. This research examines the potential hazard of Salmonella in peanut butter cookies when it is introduced via the peanut-derived ingredient. The survival of Salmonella during the baking of peanut butter cookies was determined. Commercial, creamy-style peanut butter was artificially inoculated with a five-strain Salmonella cocktail at a target concentration of 10(8) CFU/g. The inoculated peanut butter was then used to prepare peanut butter cookie dough following a standard recipe. Cookies were baked at 350 °F (177 °C) and were sampled after 10, 11, 12, 13, 14, and 15 min. Temperature profiles of the oven and cookies were monitored during baking. The water activity and pH of the inoculated and uninoculated peanut butter, raw dough, and baked cookies were measured. Immediately after baking, cookies were cooled, and the survival of Salmonella was determined by direct plating or enrichment. After baking cookies for 10 min, the minimum reduction of Salmonella observed was 4.8 log. In cookies baked for 13 and 14 min, Salmonella was only detectable by enrichment reflecting a Salmonella reduction in the range of 5.2 to 6.2 log. Cookies baked for 15 min had no detectable Salmonella. Results of this study showed that proper baking will reduce Salmonella in peanut butter cookies by 5 log or more. PMID:24680076

    Chile is recognized worldwide as an emergent economy, with a great power in natural resource exploitation. Nonetheless, despite being one of the most developed countries in Latin America, Chile imports most of the knowledge and technology necessary to drive innovation in the country. The tight budget that the Chilean government assigned to research and development and the absence of a long-term scientific agenda contributed to a limited supply of scientists over the years. In an effort to reverse this scenario, Chile has created several fellowships, such as the Becas Chile Program (BCP) to encourage new generations to pursue graduate studies to ultimately advance research and development in situ. More than 6000 fellows are now being trained abroad, accumulating an incredible potential to transform the Chilean scientific environment as we know it.  Chile now faces a greater challenge: it has to offer infrastructure and job openings to the highly skilled professionals in whom it invested. Unfortunately no clear public policies to address this situation have been developed, partially due to the lack of a dedicated institution, such as a Ministry for Science and Technology which could focalize the necessary efforts to promote such policies. Therefore, in the meantime, Chilean scientist have been motivated to create different organizations, such as, Mas Ciencia para Chile and Nexos Chile-USA, to promote constructive discussion of the policies that could be implemented to improve the Chilean scientific situation. We hope that these and other organizations have a real impact on the generation of scientific guidelines that will finally contribute to the development of the country. PMID:25309739

    Rodents play a major role in the transmission and maintenance of Salmonella contamination cycles in poultry facilities. However, very limited field data are available regarding the transmission routes, infection cycle, and shedding patterns of Salmonella by naturally infected wild rodents from commercial layer farms. In this study, a total of 128 resident wild roof rats (Rattus ratus) were captured from a Salmonella-contaminated layer facility. All roof rats were divided into 51 laboratory cages, and weekly monitoring of Salmonella fecal shedding patterns was conducted for 53 wk. Seven roof rats from cages that were observed to frequently shed Salmonella were isolated in individual cages, and daily Salmonella monitoring was performed for 35 days. At the end of monitoring, each roof rat was euthanatized, and isolation of Salmonella from different organs was performed. Results of weekly monitoring of Salmonella showed that 21 of 51 cages (41.2%) were positive for Salmonella Infantis, while two cages (3.92%) were positive for Salmonella Enteritidis. Moreover, 11 cages were positive for Salmonella for at least two sampling weeks. Isolation of Salmonella from fecal droppings was mainly observed during the first 12 wk of captivity. The longest interval between two Salmonella-positive fecal dropping was 24 wk. In the daily Salmonella monitoring, only Salmonella Infantis was isolated from fecal droppings, in which the highest number of Salmonella Infantis organisms per fecal dropping was at 1 x 10(8) colony-forming units (cfu), while the lowest measured quantity was 1 x 10(3) cfu. It was noted that the frequency of Salmonella shedding in fecal droppings appeared to have a linear correlation (r = 0.85) with the number of Salmonella organisms (cfu) per fecal pellet (P poultry facilities through intermittent fecal shedding. Moreover, Salmonella Enteritidis in wild roof rats appears to be more of a systemic infection, in which isolation is most likely to occur in internal

    Full Text Available El sufragio femenino no fue un tema que interesara solo a las mujeres, sino que involucró a todos los sectores de la vida política nacional, convirtiéndose en un hito de la historia política de Chile. Este trabajo analiza los discursos femeninos y masculinos en torno al tema, desde finales del siglo XIX hasta mediados del siglo XX (1865-1949. Hemos podido constatar que el voto de la mujer se transformó en un asunto de real importancia para las organizaciones femeninas cuando se dan cuenta de que, sin participar de la esfera política, poco podrían hacer por sus reivindicaciones civiles. En ese sentido, el discurso femenino evoluciona de un claro rechazo al sufragio, expresado hacia 1865 en El Eco de las Señoras de Santiago, a su apasionada reivindicación, en las décadas de 1930 y 1940. El discurso masculino también evoluciona de un silencio (que podemos considerar como negación a discutir el tema a lo largo del silgo XIX y en las primeras décadas del XX, a una unánime aceptación hacia la década de 1940, cuando se ve que el problema del sufragio femenino está atentando contra la imagen democrática de Chile, al tener excluida de la política a la mitad de la población por razones de género. Es por esto que consideramos que los discursos son fuentes importantes de análisis, ya que permiten observar la evolución que sufre la sociedad chilena en este período. Los argumentos que se esgrimen a favor o en contra del sufragio femenino nos hablan de una determinada forma de ver el mundo, a la mujer y a la política en el Chile de esos años, formas que tendrán que ser redefinidas y repensadas a la luz de los procesos de modernización y democratizaciónThis paper presents a study of the evolving discourse surrounding women's sufragge from the time debate on the subject began in the 1860s to the time it was finally granted in 1949.

    Full Text Available Abstract Background Salmonella can reside in healthy animals without the manifestation of any adverse effects on the carrier. If raw products of animal origin are not handled properly during processing or cooked to a proper temperature during preparation, salmonellosis can occur. In this research, we developed bioluminescent Salmonella strains that can be used for real-time monitoring of the pathogen's growth on food products. To accomplish this, twelve Salmonella strains from the broiler production continuum were transformed with the broad host range plasmid pAKlux1, and a chicken skin attachment model was developed. Results Salmonella strains carrying pAKlux1 constitutively expressed the luxCDABE operon and were therefore detectable using bioluminescence. Strains were characterized in terms of bioluminescence properties and plasmid stability. To assess the usefulness of bioluminescent Salmonella strains in food safety studies, we developed an attachment model using chicken skin. The effect of washing on attachment of Salmonella strains to chicken skin was tested using bioluminescent strains, which revealed the attachment properties of each strain. Conclusion This study demonstrated that bioluminescence is a sensitive and effective tool to detect Salmonella on food products in real-time. Bioluminescence imaging is a promising technology that can be utilized to evaluate new food safety measures for reducing Salmonella contamination on food products.

    Salmonella is an animal and human pathogen of worldwide concern. Surveillance programs indicate that the incidence of Salmonella serovars fluctuates over time. While bacteriophages are likely to play a role in driving microbial diversity, our understanding of the ecology and diversity of Salmonella phages is limited. Here we report the isolation of Salmonella phages from manure samples from 13 dairy farms with a history of Salmonella presence. Salmonella phages were isolated from 10 of the 13 farms; overall 108 phage isolates were obtained on serovar Newport, Typhimurium, Dublin, Kentucky, Anatum, Mbandaka, and Cerro hosts. Host range characterization found that 51% of phage isolates had a narrow host range, while 49% showed a broad host range. The phage isolates represented 65 lysis profiles; genome size profiling of 94 phage isolates allowed for classification of phage isolates into 11 groups with subsequent restriction fragment length polymorphism analysis showing considerable variation within a given group. Our data not only show an abundance of diverse Salmonella phage isolates in dairy farms, but also show that phage isolates that lyse the most common serovars causing salmonellosis in cattle are frequently obtained, suggesting that phages may play an important role in the ecology of Salmonella on dairy farms.

    Full Text Available The brine shrimp Artemia in Chile has been studied since the 1980s, initially on populations inhabiting shallow coastal and inland mountain ponds, and saltworks in northern and central Chile. Based on morphometric and molecular evidence, these populations were identified as A. franciscana. In the 1990s, A. persimilis was recorded from southern Patagonia, a species previously considered endemic to Argentina. Recently, two new populations of A.franciscana have been recorded, from one saline coastal pond in northern Chile and from a saltwork in central Chile. The scope for further research to increase both understanding of the strain characterization and basic population ecology descriptions of the Chilean brine shrimps and improve their conservation status is discussed. It is suggested that future studies should investigate first the management of local brine shrimp population for local aquaculture or conservation resources, other direction would be the effects of ultraviolet radiation (UVR exposition that is notoriously high in brine shrimp habitats. This last factor is very important because the UVR is an important mutagen on the genetic structure of the populations. In this scenario, it is suggest a carefully management for introduced brine shrimp populations for local aquaculture for avoid alterations in native populations that due their genetic isolation would need conservation procedures for avoid local extinctions.El camarón de salmuera o Artemia ha sido estudiado en Chile desde la década de 1980, las primeras descripciones de poblaciones fueron para lagunas someras en zonas costeras y de montana, y en salinas artificiales en la zona central y norte de Chile.

En este trabajo se tratarán algunos rasgos de la escritura de la Historia que constituyen el discurso de la ciencia y que muestran el desarrollo que va desde la Historia naturaly moral -que desde Aristótelesy Plinio representa la ciencia clásica- a los nuevos modos de conocer que representa el modelo de ciencia de la Ilustración. En consecuencia, el aporte del Abate Molina en su Compendio de la Historia Civil consiste en incorporar la concepción de progreso en los usos y costumbres de los indígenas, aportando una visión de integración diferente a la civilidad. Sabemos que con posterioridad al siglo dieciocho el aporte de muchos astrónomos, médicos y científicos jesuítas -en América- construyeron las bases de la ciencia moderna y progresiva, representando la continuidad más que la regresión en el desarrollo científico tal como lo concebimos actualmente.TheJesuit Juan Ignacio Molina vimte the Compendiode la Historia Geográfica, natural y Civil del Reyno de Chile (1776 y el Compendio de la Historia Civil del Reyno de Chile (1787 in exile in Italy.

    A total of 256 Salmonella strains consisting of 29 Salmonella serovars isolated from seafood of Cochin (India) were analyzed for resistance to antimicrobials commonly used in human and veterinary medicines as therapeutic agents. The 10 most predominant Salmonella serovars in seafood were also characterized for presence of plasmids using the alkaline lysis method. Antimicrobial susceptibility studies highlighted a comparatively high resistance in Salmonella isolates to sulfamethizol and carbenicillin, and moderate resistance to nalidixic acid and oxytetracycline. Nevertheless, antimicrobial resistance was not observed against ampicillin, ciprofloxacin, chloramphenicol, gentamicin, and kanamycin in different Salmonella serovars. Fifty percent of the Salmonella isolates, comprising 16 Salmonella serovars, were resistant to sulfamethizol followed by 39% resistant to carbenicillin and 14% resistant to oxytetracycline. Multidrug resistance was detected in 39.4%, 14.4%, 12.1%, and 1.5% of Salmonella isolates towards two drugs (sulfamethizol and carbenicillin), three drugs (sulfamethizol, carbenicillin, and oxytetracycline), four drugs (sulfamethizol, carbenicillin, oxytetracycline, and nalidixic acid), and five drugs (sulfamethizol, carbenicillin, oxytetracycline, nalidixic acid, and streptomycin), respectively. Plasmid profiling highlighted the presence of nine plasmid profiles in Salmonella serovars and plasmids that were not detected in Salmonella enterica subsp. enterica Weltevreden, Salmonella Rissen, Salmonella Bareilly, Salmonella Irumu, Salmonella Ohio, Salmonella Oslo, and Salmonella Typhi isolated from seafood.

  20. Evaluation of different analysis and identification methods for Salmonella detection in surface drinking water sources

    International Nuclear Information System (INIS)

    The standard method for detecting Salmonella generally analyzes food or fecal samples. Salmonella often occur in relatively low concentrations in environmental waters. Therefore, some form of concentration and proliferation may be needed. This study compares three Salmonella analysis methods and develops a new Salmonella detection procedure for use in environmental water samples. The new procedure for Salmonella detection include water concentration, nutrient broth enrichment, selection of Salmonella containing broth by PCR, isolation of Salmonella strains by selective culture plates, detection of possible Salmonella isolate by PCR, and biochemical testing. Serological assay and pulsed-field gel electrophoresis (PFGE) can be used to identify Salmonella serotype and genotype, respectively. This study analyzed 116 raw water samples taken from 18 water plants and belonging to 5 watersheds. Of these 116, 10 water samples (8.6%) taken from 7 water plants and belonging to 4 watersheds were positive for a Salmonella-specific polymerase chain reaction targeting the invA gene. Guided by serological assay results, this study identified 7 cultured Salmonella isolates as Salmonella enterica serovar: Alnaby, Enteritidis, Houten, Montevideo, Newport, Paratyphi B var. Java, and Victoria. These seven Salmonella serovars were identified in clinical cases for the same geographical areas, but only one of them was 100% homologous with clinical cases in the PFGE pattern. - Research highlights: → A new Salmonella detecting procedure for environmental water is developed. → Salmonella isolates are identified by serological assay and PFGE. → A total of seven Salmonella serovars is isolated from environmental water.
