Fluconazole susceptibility of Italian Candida dabliniensis clinical isolates determined by reference and simplified tests

2001

Candida dubliniensis ia an opportunistic pathogen mainly associated with oral candidiasis in human immunodeficiency virus (HIV)-infected individuals. We recently recovered the first Italian clinical isolates of C. dubliniensis from the oral cavities of seven HIV-seropositive subjects. The in vitro susceptibility to fluconazole (FLCZ) of these isolates was determined according to the National Committee for Clinical Laboratory Standards (NCCLS) M27-A broth microdilution method for yeasts. All seven isolates of C. dubliniensis were susceptible to FLCZ (MICs < or =0.5 microg/ml). Results of this reference method were compared to those obtained with simplified tests, more adapted to routine eval…

2015

Resumen El Programa de Control de Calidad Externo de la Sociedad Espanola de Enfermedades Infecciosas y Microbiologia Clinica incluye las areas de bacteriologia trimestral y mensual, serologia, micologia, parasitologia, micobacterias, virologia, microbiologia molecular y cargas virales del virus de la inmunodeficiencia humana-1, virus de la hepatitis C y virus de la hepatitis B. En este manuscrito se presenta el analisis de los resultados remitidos por los participantes en los controles enviados durante el ano 2013, exceptuando los correspondientes a cargas virales, que se presentan en un manuscrito aparte. Los resultados obtenidos confirman de nuevo la buena capacitacion general de los lab…

Characterization and multicentric validation of a common standard for Toxoplasma gondii detection using nucleic acid amplification assays.

2014

ABSTRACT The molecular diagnosis of toxoplasmosis essentially relies upon laboratory-developed methods and suffers from lack of standardization, hence the large diversity of performances between laboratories. Moreover, quantifications of parasitic loads differ among centers, a fact which prevents the possible prediction of the severity of this disease as a function of parasitic loads. The objectives of this multicentric study performed in eight proficient laboratories of the Molecular Biology Pole of the French National Reference Center for Toxoplasmosis (NRC-T) were (i) to assess the suitability of a lyophilized preparation of Toxoplasma gondii as a common standard for use in this PCR-base…

Comparison of disc diffusion assay with the CLSI reference method (M27-A2) for testing in vitro posaconazole activity against common and uncommon yea…

2007

Objectives To evaluate the suitability of disc diffusion (DD) assay for testing posaconazole activity and to corroborate its activity against recently isolated yeasts by the CLSI reference microdilution M27-A2 method. Methods A total of 224 yeast isolates (7 species with 52 to 11 isolates each, and 15 species with 1 to 6 isolates) were evaluated, 125 were recent bloodstream isolates, 30 isolates from other sources and six ATCC isolates that included amphotericin B-resistant Candida albicans ATCC 200955, Candida lusitaniae (ATCC 200950, 200951, 200952 and 200953) and amphotericin B- and itraconazole-resistant Candida tropicalis ATCC 200956. MICs were determined at 24 and 48 h by following th…

More than Pneumonia: Distinctive Features of SARS-Cov-2 Infection. From Autopsy Findings to Clinical Implications: A Systematic Review

2020

Despite safety recommendations for the management of corpses with COVID-19 infection and the high number of deaths worldwide, the post-mortem investigation rate is extremely low as well as the scientific contributions describing the pathological features. The first results of post-mortem investigations provided interesting findings and contributed to promoting unexplored therapeutic approaches and new frontiers of research. A systematic review is provided with the aim of summarizing all autopsy studies up to February 2020 in which a complete post-mortem investigation in patients with COVID-19 disease was performed, focusing on histopathological features. We included case reports, case serie…

Characterization of MEMS accelerometer self-noise by means of PSD and Allan Variance analysis

2017

In this paper, we have studied the sources of error of a low-cost 3-axis MEMS accelerometer by means of Power Spectral Density and Allan Variance techniques. These techniques were applied to the signals acquired from ten identical devices to characterize the variability of the sensor produced by the same manufacturer. Our analysis showed as identically produced accelerometer have somehow variable behavior in particular at low frequency. It is therefore of paramount importance before their use in Inertial Navigation or Earthquakes Monitoring System, a complete characterization of each single sensors.

Syntaxonomy and ecology of thermophilous deciduous open woodlands and scrub vegetation in Tajikistan (Middle Asia)

2022

In this paper we present the first syntaxonomic classification for the thermophilous open wood and scrub vegetation in Tajikistan with some remarks on its environmental gradients. Altogether 143 relevés were sampled between 2014–2021 using the seven-degree cover-abundance scale of Braun-Blanquet. They were classified by the modified TWINSPAN method with the use of the four step interval scale with cutoff levels of 0%, 2%, 5% and 10% and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. Detrended Correspondence Analysis was used to determine the relation between samples, vegetation units and the major grad…

Las culturas de la emigración española: reflejos audiovisuales de la clase obrera

2019

[spa] El objetivo del presente artículo es estudiar la representación de la emigración española hacia Europa, colocando el acento en su pertenencia a la clase obrera. Por ello, consideraremos films rodados en el contexto franquista, propuestas realizadas al margen de la industria o militantes, películas producidas por los países de acogida o audiovisuales dirigidos por personas que hayan vivido la experiencia de la emigración (primera y segunda generación). Todas estas distintas variables nos permitirán conocer y estudiar la complejidad que entraña abordar este tema y a su vez también analizaremos la relevancia que se concede en estos títulos a la condición obrera. Asimismo, valoraremos la …

Nutritional Profiling and the Value of Processing By-Products from Gilthead Sea Bream (

2019

Fish processing industries generate a large volume of discards. In order to fulfil with the principles of a sustainable circular economy, it is necessary to maintain aquaculture by-products in the food chain through the production of high-value biomolecules that can be used as novel ingredients. In this study, we try to give value to the gilthead sea bream by-products, evaluating the composition and the nutritional value of the muscle and six discards commonly obtained from the fish processing industry (fishbone, gills, guts, heads, liver, and skin), which represent ≈ 61% of the whole fish. Significant differences were detected among muscle and by-products for fatty acid and amino acid prof…
