Detection of Clostridium difficile antigen and toxin in stool specimens: Comparison of the C. difficile quik chek complete enzyme immunoassay and GeneXpert C. difficile polymerase chain reaction assay
BACKGROUND/AIMS Accurate and rapid laboratory diagnosis of Clostridium difficile infections (CDI) remains a significant challenge. A two-step algorithm for detection of toxigenic C. difficile in stool based on initial screening for glutamate dehydrogenase assay followed by confirmation by toxin A+B detection using an enzyme immunoassay (EIA) or molecular assay has been proposed. We aimed to eva...
متن کاملEvaluation of enzyme immunoassays to detect Clostridium difficile toxin from anaerobic stool culture.
Stool culture for Clostridium difficile, while necessary for strain typing and antimicrobial surveillance, cannot determine toxin production. We prospectively tested in triplicate 91 C difficile cultured isolates for toxin production by 2 enzyme immunoassays (EIAs) (Meridian Premier Toxins A&B, Meridian Bioscience, Cincinnati, OH; and TechLab Tox A/B II, TechLab, Blacksburg, VA) and cytotoxin n...
متن کاملA Rapid Enzyme Immunoassay for the Detection of Clostridium difficile Toxins A and B in Stool Specimens
AND EXPLANATION OF THE TEST Toxigenic Clostridium difficile is the leading cause of nosocomial infectious diarrhea in developed countries. An estimated 300,000 cases of C. difficile associated disease (CDAD) are seen per year in U.S. hospitals alone. 2 Clostridium difficile is the etiologic agent in approximately 25% of all cases of antibiotic-associated diarrhea. Virtually any antibiotic can p...
متن کاملDetection of vancomycin-resistant enterococci (VRE) in stool specimens submitted for Clostridium difficile toxin testing
The aim of this study was to determine the association between Clostridium difficile (C. difficile) and vancomycin-resistant Enterococcus (VRE) and efficacy of screening stools submitted for C. difficile toxin assay for prevalence of VRE. Between April 2012 and February 2014, 158 stool samples submitted for C. difficile toxin to the Marmara University Microbiology Laboratory, were included in t...
متن کاملSpecific detection of toxigenic strains of Clostridium difficile in stool specimens.
Clostridium difficile is the infectious agent responsible for antibiotic-associated colitis. We report the use of the polymerase chain reaction technique to identify toxigenic strains of C. difficile in human stool specimens. A set of primers based on the nucleotide sequence of the toxin B gene, which amplified a 399-bp fragment from isolates producing toxin B, was designed. We examined 28 know...
