Prevalence and Risk Factors for the Carriage of Bacteria and Clostridioid in Elderly Dependent Persons

Study Overview
=================
Brief Summary
-----------------
Brief summary : Very few studies have evaluated the prevalence of multi-drug resistant (MDR), highly resistant emerging bacteria and Clostridioides difficile toxinogenic (CDt) in residents and in healthcare workers (HCW) in nursing home (NH). Most of study were conducted in acute care services and were limited to specific bacterial species. Hypothesis : The carriage of MDR bacteria in resident may be a risk factor for an outbreak in NH or in healthcare facility. Primary outcome: The objective of this study is to estimate the prevalence for carriage of MDR bacteria and CDt in residents in NH. Secondary outcomes: Estimate the prevalence for carriage of MDR bacteria and CDt toxigenic in HCW in NH. Identify the risk factors for carriage of MDR bacteria and CDt in residents in nursing home Identify the risk factors for carriage of MDR bacteria and CDt in healthcare workers in NH Evaluate the presence of cross-transmission of MDR bacteria and CDt in one or several NH Evaluate the association between the presence of cross-transmission of MDR bacteria and CDt in a NH and the management of infection control Establishment a collection of stool samples
