TL;DR: This study compares the validation of three different molecular assays at the Johns Hopkins Molecular Virology laboratory: the RealStar® SARS-CoV-2 RT-PCR, ePlex® Sars-Cov-2, and the CDC COVID-19 RT- PCR tests and indicates a comparable analytical performance of the three assays for the detection of SARS.
Journal ArticleDOI
Impact of Toxigenic Clostridium difficile Colonization on the Risk of Subsequent C. difficile Infection in Intensive Care Unit Patients
Sarah Tschudin-Sutter,Karen C. Carroll,Pranita D. Tamma,Madeleine L. Sudekum,Reno Frei,Andreas F. Widmer,Brandon Ellis,John G. Bartlett,Trish M. Perl +8 more
TL;DR: In intensive care unit patients, colonization with toxigenic C. difficile is an independent risk factor for development of subsequent CDI, and colonization on admission and colonization during hospitalization were independent predictors of CDI.
Journal ArticleDOI
