Identificazione e caratterizzazione di consorzi microbici causa di deterioramento per i beni culturali e potenziali patogeni per l'uomo.

Identification of microbial taxa involved in cultural heritage deterioration and able to produce health hazardous substances by molecular techniques.

Fungi and bacterial, wide-spread in biosphere environments, are the main microorganisms related to the deterioration of cultural assets but, moreover, complex microbial communities may emit mixed aerosol into indoor air. In this study the microbial colonization is investigated from to point of view, conservation of cultural heritage and related potential illness to visitors or professionals. The sampling was performed by non-destructive procedures on works of art surfaces, and by the gelatin membrane filter method (Sartorius) for aerosol. The identification of microbial taxa was performed by molecular analyses based on PCR, sequencing, sequence comparison techniques and, particularly for fu…

Characteristics of SARS-CoV-2 variants of concern B.1.1.7, B.1.351 or P.1: data from seven EU/EEA countries, weeks 38/2020 to 10/2021

COVID study groups - PORTUGAL: Portuguese Laboratory Network for the Diagnosis of COVID-19 and Public Health Department of the Health Administrative Regions, Physicians that provided data and samples from suspected cases and SARS-CoV-2 genetic characterization. INSA laboratory team for the diagnosis of SARS-CoV-2. Algarve Biomedical Center and Unilabs. We compared 19,207 cases of SARS-CoV-2 variant B.1.1.7/S gene target failure (SGTF), 436 B.1.351 and 352 P.1 to non-variant cases reported by seven European countries. COVID-19 cases with these variants had significantly higher adjusted odds ratios for hospitalisation (B.1.1.7/SGTF: 1.7, 95% confidence interval (CI): 1.0-2.9; B.1.351: 3.6, 95…
