Its impact far exceeds the phenomenal discoveries of antibiotics and any modern surgical advances. Beaches in the Isle of Man and Cambois in the Northeast of England were designated as sites for the study of the impacts of sewage discharges from marine outfalls on the aesthetics and bacteriological quality of beaches/bathing waters. Aesthetic studies showed beaches littered with sewage derived debris, (SDD) considerably worse after heavy rainfall. The presence of SDD such as faeces, sanitary wear, floating debris, unsightly surface slicks, and discoloration are the most important features associated in the public mind with sewage pollution. Liquid and floatable solid wastes discharged at any level under seawater rise to the surface and strong winds override tidal currents in determining their direction/dispersion. Fresh sewage discharged from marine outfalls returned to pollute the study beaches/bathing waters within three hours of discharge. Culture-based enumeration methods estimated total populations of bacteria in bathing/offshore seawater samples. Total coliform and E.coli densities in bathing water samples exceeded the UK EC mandatory standards. Quantitative Rhodamine-wt tracer Dye concentrations could not be used to accurately model the dispersion of sewage bacteria in the marine environment. ····· 10361118036

Two decades following the introduction of antibiotics, the medical community began to see a disturbing trend. Bacterial infections that were once treatable no longer responded to antibiotics. Over the next decade our antibacterial arsenal will begin to fail at an ever increasing rate. Epidemiologists now warn of epidemic diseases that are not treatable by modern means. But it turns out that herbal medicines, those most ancient of human helpers, are effective against antibiotic resistant bacteria for they are much more complex than antibiotics and bacteria cannot develop resistance to them.Hence to overcome the odds posed by antibiotics and other means allopathic medicine, plant resources seems to be only solution. Every plant species has medicinal properties, many of which are yet to be explored. This research is one such attempt. ····· 10361117966

However, nowadays it is seen as an importantopportunistic pathogen and ranks first among thecausative agents of nosocomial infections onindwelling medical devices. Infections with thisleading pathogen are characterized by biofilmdevelopment on devices (heart valves, catheters,contact lenses, etc.) and this factor is consideredthe main virulence mechanism of S. epidermidis.Biofilm cells are organised into structuredcommunities enclosed within a matrix of extracellularmaterial. These cells are phenotypically differentfrom planktonic or suspended cells notably, theyresist host defences and display a significantlydecreased susceptibility to antimicrobial agents.Since biofilm-associated infections are frequentlyresistant to conventional antimicrobial therapy, thework presented in this book aimed at studying newtherapeutic strategies for treatment and control ofinfections caused by S. epidermidis. ····· 10361117944
für 62.91€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Pasteurella multocida es un agente capaz de producir diferentes patologías en el ganado porcino. Se trata de una bacteria muy heterogénea, por lo que su caracterización fenotípica y genética es fundamental para el tratamiento y control de las enfermedades que produce. El objetivo de este trabajo fue determinar las variedades presentes en aislados españoles. Los resultados demostraron que todas las cepas implicadas en diferentes procesos clínicos pertenecían a la subespecie multocida, la mayoría eran de tipo capsular A y carecían de la toxina dermonecrótica. Respecto a las variedades bioquímicas, el biovar 3 fue el mayoritario, estando asociado al gen de virulencia hgbB. Sin embargo, el biovar 2, aunque menos prevalente, se encontró en una proporción de aislados mayor de lo esperado y siempre asociado al gen pfhA. Utilizando la técnica molecular de PFGE (Pulsed Field Gel Electrophoresis) se determinó que a pesar de la variabilidad genética existente ciertos patrones genéticos están ampliamente distribuidos y pueden estar implicados en distintos procesos clínicos. Se demostró la utilidad de combinar diversas metodologías para lograr una caracterización exhaustiva de las cepas. ····· 10361117597

Candida dubliniensis produjo proteinasas y fosfolipasas en menor proporción que Candida albicans. La capacidad de adherencia de C. dubliniensis fue similar a la de C. albicans. La respuesta al estrés oxidativo con peróxido de hidrógeno y metil viológeno fue menor que para C. albicans. Algunas enzimas como catalasa, glucosa 6P deshidrogenasa y superóxido dismutasa aumentaron el 100% para C. dubliniensis y menos del 50% para C. albicans. Se extrajo ADN de P. brasiliensis y se diseñó una PCR para amplificar un fragmento de ADN del gen que codifica para gp43, ligándose este fragmento a un vector pGEX. Se transformó una cepa de E. coli para expresar una proteína recombinante de 11 kDa como proteína de fusión a GST. Esta proteína se expresó como cuerpos de inclusión.

A pesar que hasta la fecha se han identificado más de 3.000 enzimas diferentes, y muchas de ellas han encontrado utilidad en aplicaciones biotecnológicas, no es posible satisfacer todas las demandas debido a la baja productividad de los microorganismos silvestres y a que generalmente estas enzimas no son lo suficientemente robustas como para ser aplicadas en dichos procesos. Como resultado, la búsqueda, aislamiento y caracterización de microorganismos capaces de sobrevivir en ambientes extremos como fuente de nuevas enzimas recibe gran atención por parte de investigaciones en Biotecnología.

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Four bacterial cytochrome P450 enzyme activities are described in terms of their potential biotechnological use for steroid transformations, by engineered `Rhodococcus` strains, into commercially valuable compounds. Three selected rhodococcal P450s were characterized with microbiological, genetic, biochemical, spectroscopic and chromatographical methods. Two sterol C26- hydroxylases were demonstrated to be important for 3- hydroxysterol degradation. The role of the novel dextromethorphan N-demethylase in sterol metabolism was discussed. Furthermore, heterologous production of a mutated P450 enzyme, from `Bacillus megaterium`, was shown in an engineered `Rhodococcus` strain. The activity of the mutated P450 was identified as 16 -hydroxylase of 4- androstene-3,17-dione, by ¹H and ¹³C NMR. The detailed characterization of the cytochrome P450 enzymes, described in this book, provides insight into the catabolic repertoire of selected bacterial strains, necessary for engineering of steroid catabolic pathways in order to produce pharmaceuticals efficiently. ····· 10361115841

In the last twenty years this plant has been successfully used as a model plant to investigate the induction of defense pathways after exposure to fungal, bacterial and abiotic molecules, showing triggering of different mechanisms of resistance. Understanding these mechanisms in order to improve crop protection is a main goal for Plant Pathology. The aim of this study was to search for general or race-specific molecules able to determine in Solanum lycopersicon immune responses attributable to the main systems of plant defense: non-host, host-specific and induced resistance.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The E-protein E2A is well known for its many roles during B cell development. Antigen receptor signaling that leads to inhibition of E2A by the calcium-sensor protein calmodulin (CaM) has therefore very broad implications. The down- regulation of the surrogate light chains of the pre-B cell receptor and also the co-receptor CD19 was shown to be through CaM inhibition of E2A. Furthermore, several components of the Ig recombination machinery including RAG1 and RAG2 are down-regulated by this mechanism, and the recombination complex was shown to include the RAGs, Pax5 and E2A, which can be directly released from the Ig heavy chain locus by pre-B cell receptor signaling through CaM to achieve allelic exclusion. The tight regulation of the antibody diversification enzyme AID is also dependent on CaM inhibition of E2A, and a negative feedback regulation of the pre-B and B cell receptor proteins and co-receptors and proteins in signal pathways from the receptor was also shown to occur through E2A inhibition by CaM. Plasma cell differentiation is induced by very fast regulatory events, which are shown to be dependent on CaM inhibition of E2A. ····· 10361115300
