[Legionella spp. contamination in indoor air: preliminary results of an Italian multicenter study].

2014

Obiettivo. Rilevare la presenza di Legionella spp. nell’aria attraverso un protocollo standardizzato, a fianco dei tradizionali metodi impiegati per la rete idrica. Disegno. In dieci strutture sanitarie è stato selezionato un bagno, la cui acqua presentava una contaminazione da Legionella >1.000 unità formanti colonie (ufc)/litro. La contaminazione dell’aria è stata valutata tramite campionamento attivo (Surface Air System, SAS) e passivo, impiegando piastre di sedimentazione per la valutazione dell’Indice Microbico Aria (Index of Microbial Air, IMA). I campionamenti sono stati effettuati per 8 ore consecutive, a circa 1 m dal pavimento e a 50 cm dal rubinetto. Con il campionamento attivo, …

Control and prevention measures for legionellosis in hospitals: A cross-sectional survey in Italy

2018

Abstract Risk assessment, environmental monitoring, and the disinfection of water systems are the key elements in preventing legionellosis risk. The Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine, and Public Health and the Italian Multidisciplinary Society for the Prevention of Health Care-Associated Infections carried out a national cross-sectional survey to investigate the measures taken to prevent and control legionellosis in Italian hospitals. A multiple-choice questionnaire was developed, comprising 71 questions regarding hospital location, general characteristics, clinical and environmental surveillance, and control and preventive measur…

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…

Wastewater surveillance of SARS-CoV-2 variants in October-November 2022 in Italy: detection of XBB.1, BA.2.75 and rapid spread of the BQ.1 lineage

2023

This study adds insight regarding the occurrence and spread of SARS-CoV-2 Variants of Concern (VOCs) and Var-iants of Interest (VOIs) in Italy in October and November 2022, by testing urban wastewater collected through-out the country. A total of 332 wastewater samples were collected from 20 Italian Regions/Autonomous Provinces (APs) within the framework of national SARS-CoV-2 environmental surveillance. Of these, 164 were collected in the first week of October and 168 in the first week of November. A similar to 1600 bp fragment of the spike protein was sequenced by Sanger (for individual samples) and long-read nanopore sequencing (for pooled Region/AP samples).In October, mutations charact…
