Serological and molecular identification of Legionella spp. isolated from water and surrounding air samples in Italian healthcare facilities
2016
Abstract Background Legionella is an intracellular microorganism living in natural and artificial aquatic environments. Although its transmission to humans is linked to the inhalation of contaminated aerosols, there is no validated air sampling method for the control and prevention of the disease. The aim of the present study was to provide more information on the distribution of Legionella spp. in indoor environments and to determine whether the same Legionella strains are isolated from air and water samples. Methods Ten healthcare facilities located in seven regions of Italy were enrolled. The serological typing of Legionella spp. from water samples and the surrounding air by active and p…
Is there a microbial sub alpha-diversity at soil microscale ?
2012
The distribution of the soil microbial diversity depends on a broad range of environmental filters nested in spatial scales from continent to millimeter. Although microbial biogeography studies have recently shown the influence of environmental factors (texture/pH/plant cover and land-use) on soil microbial abundance and diversity, little is still known about spatial heterogeneity at a micro-scale within soil. Our study aims at describing and understanding the distribution of abundance and diversity of soil microbial communities between different soil microenvironments. Four soils were selected on the basis of differences in physico-chemical properties and historical land-management practic…
Formation of microbial organic carbonates during the Late Jurassic from the Northern Tethys (Amu Darya Basin, Uzbekistan): implications for Jurassic …
2020
23 pages; International audience; The Late Jurassic was a period of major global carbon cycle perturbations with episodes of anoxia leading to regional accumulation of organic matter in sediments worldwide. The Tubiegatan section (SW Gissar Mountains, Uzbekistan) located in the Northern Tethys, shows atypical organic-rich limestone and marl deposits (up to 6% of total organic carbon) marked by pronounced negative excursions of δ13Ccarb (amplitude of ca. 12‰) and δ13Corg (amplitude of ca. 4‰) recorded during the Middle Oxfordian (Transversarium Zone). A transdisciplinary approach including sedimentology, palynofacies characterization, mineralogy, organic and inorganic geochemistry was carrie…

Manual de Practiques: Microbiología Ambiental. Grau de Ciències Ambientals
Microbiologia : Grau de Biologia
2013
L'assignatura de Microbiologia es troba situada en el tercer curs del Grau en Biologia de la Universitat de València. És una assignatura obligatòria que ha estat precedida per l'estudi, entre altres, de Biologia Cel•lular i Bases Moleculars i Genètiques dels Éssers Vius, en les quals l'alumnat ha desenvolupat i assimilat coneixements bàsics que serviran de base a la Microbiologia. És per això que l'assignatura no desenvoluparà aquests aspectes bàsics, ja que se suposen adquirits (citologia de la cèl•lula eucariota, les bases de genètica i biologia molecular, metabolisme i regulació, etc.), però pressuposarà el seu coneixement. Així mateix, i atès que s'estudia en paral•lel amb l'Ecologia, t…
Laboratori de Microbiologia
2020
El document forma part dels materials docents programats mitjançant l'ajut del Servei de Política Lingüística de la Universitat de València - Idioma Valencià Aquest document ofereix una visió específica de les diferents pràctiques de laboratori que es desenvolupen dins de l´àrea de Microbiologia. L´objectiu és proporcionar a l´alumnat un material gràfic i de contingut, en referència als medis de cultiu, eines, equipament, procediments i bacteris més comunament assajats al laboratori, facilitant la transmissió de coneixements dins d´aquest camp d´estudi. Aquest material proporciona també discussió i contextualització dels problemes i experiments plantejats al laboratori, justificant així la …

Candida parapsilosis Infection:A Multilocus Microsatellite Genotyping-Based Survey Demonstrating an Outbreak in Hospitalized Patients
2020
Microsatellite analysis identifies specific genotypes and the genetic relationship between strains. Our objective was to analyze the genotypes of C. parapsilosis strains isolated on different wards of aTertiary- Referral University Center. We evaluated 70 C. parapsilosis strains in total, isolated from samples of patients admitted to five different wards over two years (January 2015-December 2016). Eight microsatellite markers were selected, and two multiplex PCR assays were set up for microsatellite analysis. The 70 strains, examined at eight microsatellite loci, showed 46 different multilocus genotypes profiles. A total of 74 alleles were detected, with an average of 9.25 alleles per locu…
Pre-operative leukocytosis: a potential poor prognosis risk factor in cardiac device implantation: a case report
2022
Introduction. Despite the benefits of the implantation of cardiac rhythm management devices cardiac implantable electronic device (CIED) infection is an emerging problem New debate emerged about the unclear role of the pre-operative alteration of pro-inflammatory parameters, such as leukocytosis, in the development CIED infection and/or heart failure, and its consequent impact on the timing of ICD implantation/reimplantation. Case report. A 65 years old patient with a history of Diabetes Mellitus (DM) type II, ventricular and supraventricular arrhythmias, chronic myocardial ischemia, heart failure was admitted to hospital.Healthcare workers opted for ICD implantation despite the presence of…
