Caracterización de Escherichia coli productora de toxina Shiga aislada desde perros y gatos de comunas de la Región Metropolitana
(Universidad de Chile, 2019)
Escherichia coli productora de toxina Shiga (STEC) es un patógeno zoonótico emergente, que puede causar enfermedades severas en humanos, como colitis hemorrágica (CH) y síndrome hemolítico urémico (SHU). Se han reportado infecciones con STEC en...
Shiga toxin-producing Escherichia coli (STEC) is an emerging zoonotic pathogen, which can cause severe diseases in humans, such as hemorrhagic colitis (HC) and haemolytic uraemic syndrome (HUS). Infections have been reported in people as a result of direct contact with companion animals, and from these STEC strains with virulotype associated with severe disease have been isolated. However, to date in Chile there is no information available about it. For this reason, this project seeks to provide information on the characterization of circulating STEC strains in part of the national dog and cat population. In order to comply with the above, rectal swabs from 300 dogs and 300 pet cats were collected between October and December of 2018. Two rounds of culture were carried out in tripticase soy broth and on MacConkey agar; and by means of PCR, the presence of the stx1 and stx2 genes was attempted in order to identify STEC strains in the samples obtained. In addition, the detection of eae, lpf, saa and hlyA genes in the isolated STEC strains was contemplated. However, with this methodology it was not possible to isolate STEC strains in the processed samples. In view of the results obtained, we can conclude that household dogs and cats in some communes of the Metropolitan Region would represent a low risk in the transmission of STEC strains with virulence determinants associated with HC and HUS in people. However, it is necessary to carry out further studies, with a larger sample size and that address the different variables that may affect the colonization of STEC in these animals....

Sistema de gestión y valorización de residuos sólidos orgánicos de ferias libres en la comuna de Ñuñoa
(Universidad de Chile, 2018)
RESUMEN
El crecimiento sostenido de la población, la necesidad de alimentación y la cultura de
consumo presente en la sociedad actual, han generado como consecuencia la producción
de grandes volúmenes de residuos. Durante el año 2014, Chile generó un...

Enriquecimiento de helado con triacilglicéridos estructurados de epa, dha y ácido caprílico, de acidólisis enzimática (Candida antarctica) de AGPICL n-3 y aceite refinado comercial de salmónidos
(Universidad de Chile, 2017)
Hoy en día, los aceites de origen marino son productos valiosos con gran aplicación nutricional por su alto contenido de ácidos grasos poliinsaturados de cadena larga omega-3 (AGPICL n-3), principalmente el ácido eicosapentaenoico (C20:5, EPA) y el...
Nowadays oil from marine origin are valuable products with great nutritional application due to their high content of omega-3 long chain polyunsaturated fatty acids (AGPICL n-3), mainly eicosapentaenoic acid (C20: 5, EPA) and docosahexaenoic acid (C22: 6, DHA). These fatty acids are known for their multiple health benefits, being associated with protection against cardiovascular, the optimal development of neural, regulating imflammation, and others. However, the consumption of seafood in Chile is quite low with respect to the world average, due to the above, the present work studied the enrichment of a cream matrix of ice cream with the addition of EPA, DHA and caprylic acid structured triacylglycerols (TAGs), obtained from the purification of the product generated in the enzymatic acidolysis process (Candida antarctica) of commercial refined oil of salmonids and concentrate of AGPICL n-3 of commercial crude oil of salmonids under conditions of supercritical carbon dioxide. The commercial crude oil of salmonids AGPICL n-3 concentrate was obtained by saponification and subsequent inclusion with urea crystals for the exclusive production of AGPICL n-3, EPA and DHA. The enrichment of ice cream was carried out with the addition of EPA and DHA TAGs by optimizing the variables of the homogenization process, EPA and DHA concentration and stirring speed using a factorial design 22 with 2 repetitions at the center point of the coded variables (0,0) according to response surface methodology. The effect of the homogenization process on thermal behavior was studied by differential scanning calorimetry (DSC) for the variables response mouth melt measured at 10°C and thermal resistance measured at 0°C. The values obtained for the optimization of the response variables, mouth melt and thermal resistance with respect to control ice cream were 6056 rpm for the agitation speed and 151 mg of EPA and/or DHA TAGs in the enrichment of the cream in the ice cream matrix. So this study allows to complement the intake of fish with a product of mass consumption, besides representing an approach to the optimal levels of omega-6 and omega-3 fatty acids in a food especially attractive for children...
