Prevalence of diagnostically-discrepant Clostridioides difficile clinical specimens: insights from longitudinal surveillance

Frontiers in Medicine, 2023
BackgroundClostridioides difficile Infection (CDI) is a healthcare-associated diarrheal disease prevalent worldwide. A common diagnostic algorithm relies on a two-step protocol that employs stool enzyme immunoassays (EIAs) to detect the pathogen, and its

Possibility of a life-time extension for wwer-1000 reactor pressure vessels beyond the design period

Trudy Odesskogo Politehničeskogo Universiteta, 2020
At present a life-time extension for WWER-1000 reactor pressure vessels is an actual issue in Ukraine. For a decision about the life-time extension it is needed to assess mechanical properties and the critical brittleness temperature TK for the RPV ...

Optimum Diagnostic Assay and Clinical Specimen for Routine Rotavirus Surveillance [PDF]

Journal of Clinical Microbiology, 2008
ABSTRACT Rates of detection of rotavirus were compared by diagnostic assay and specimen type. For bulk stools, rates of detection by reverse transcriptase PCR (RT-PCR) and enzyme immunoassay (EIA) were similar, but 18% of healthy controls tested positive by RT-PCR. Testing of bulk stools by EIA appears to be optimum for rotavirus surveillance.
