Molecular characterisation of a dominant methicillin-resistant Staphylococcus aureus (MRSA) clone in a Mexican hospital (1999-2003)

Abstract

In this paper, we propose a comprehensive methodology to specify prior distributions for commonly used models in reliability. The methodology is based on characteristics easy to communicate by the user in terms of time to failure. This information could be in the form of intervals for the mean and standard deviation, or quantiles for the failure-time distribution. The derivation of the prior distribution is done for two families of proper initial distributions, namely s-normal-gamma, and uniform distribution. We show the implementation of the proposed method to the parameters of the s-normal, lognormal, extreme value, Weibull, and exponential models. Then we show the application of the procedure to two examples appearing in the reliability literature, [26] and [28]. By estimating the prior predictive density, we find that the proposed method renders consistent distributions for the different models that fulfill the required characteristics for the time to failure. This feature is particularly important in the application of the Bayesian approach to different inference problems in reliability, model selection being an important example. The method is general, and hence it may be extended to other models not mentioned in this paper.

The analysis strategies include the iden-tification of discursive actions and processes within each of the three fields that characterize students' communicative actions: the field of science, the field of English, and the field of science education. Finally the questions that orient the analysis within and across fields are presented whose general aim is constituted by the main question: How can learning in CLIL science teacher education contexts occur?",,,,,,,,,"http://hdl.handle.net/20.500.12104/39129","http://www.scopus.com/inward/record.url?eid=2-s2.0-84906717702&partnerID=40&md5=3e860d9ebef32280fbf1570d2e4af483",,,,,,"3",,"Ensenanza de las Ciencias",,"27

El objetivo de este estudio es el de identificar la relación de la preferencia manual como un reflejos de las asimetrías básicas de los dos hemisferios funcionales, mediante dos pruebas de preferencia manual en niños escolares. El estudio se realizó con una muestra de 263 niños de ambos sexos de 6 a 8 años de edad, inscritos en las escuelas primarias ubicadas en la zona urbana del Municipio de Guadalajara, Jalisco. Los criterios que se utilizaron para la distribución de los niños en los grupos de preferencia manual derecha, izquierda y mixta, se obtuvieron con los puntajes totales obtenidos, a través de un punto de corte, determinóndose el valor mayor, menor o igual 3 en la prueba de pinchado de Tapley y Bryden (1985) y el valor mayor, menor o igual 5 en la prueba de dedo de Halstead y Reitan (1993). Para la medición de la desnutrición se utilizó la técnica de J. Waterlow (1977). Se identificaron porcentajes altos de una preferencia manual diestra, 52.0%; zurda 14.0% y mixta 33.9% de los niños desnutridos y un menor porcentaje de una preferencia manual mixta 29.3% y zurda 12.0% en niños normales y sólo se presento en la preferencia manual diestra en un 58.7% en los niños normales. Se llegó a la conclusión de que hay diferencias por edad y sexo en la estabilidad de preferencia manual; los niños desnutridos de 6 años aun no contaban con una adecuada estabilidad con la manualidad diestra, mientras que en los niños de 7 y 8 años ya estaba normalmente establecida, a diferencia de los niños normales en que la preferencia manual ya estaba establecida desde los 6 años.",,,,,,,,"1665-3572","http://hdl.handle.net/20.500.12104/39083","http://www.cucs.udg.mx/revistas/edu_desarrollo/anteriores/3/003_Flores.pdf; http://132.248.9.1:8991/F/T2YHQN5JKYSPCIP3SAPK3TB1KGTDDEFCSVNH496MXCXGEJUB2B-14508?func=full-set-set&set_number=025047&set_entry=000900&format=999",,"Español",,,,"3",,"Revista de Educación y Desarrollo (UDEG)",,"65-72",,,,"CLASE

Representatives of the single clonal type found were analysed by spa typing, multilocus sequence typing and staphylococcal chromosomal cassette mec (SCCmec) typing, and were tested for the presence of 22 virulence determinants and agr type. A single PFGE pattern was identified, with minor variations over time, with spa type 2, sequence type 5, SCCmec type II, agr type 2 and the presence of the enterotoxin genes seg and sei, the ?-haemolysin variant gene hlg-v and the leukocidin lukE-lukD genes. In addition, the isolates showed antimicrobial resistance to ?-lactams, macrolides, chloramphenicol and imipenem, and susceptibility to gentamicin, rifampicin, trimethoprim-sulphamethoxazole and vancomycin. Following its appearance in 1997, this clone spread within the hospital, and is now present in most of the hospital units and wards.
