Clinical Outcome of C. difficile-Toxin Negative, PCR-Positive PatientsUsmani, AsharBoyce, JohnThe American Journal of Gastroenterology
In June 2017 for the diagnosis of Clostridioides difficile infection (CDI), Renown Health transitioned from utilizing polymerase chain reaction (PCR) to a two-step algorithm of PCR followed by toxin enzyme immunoassay (EIA) if PCR was positive. Providers were encouraged to forgo treatment in ...
Studies have shown that toxin detection identifies those who require treatment for C. difficile infection (CDI) and free toxin can be predicted with high negative predictive value from PCR cycle threshold (CT). CT-toxin was introduced at our institution in two phases: from October 2016 to ...
To determine how the host responds toC. difficiletoxin-induced inflammation, we compared the cecal tissue gene expression between three groups of mice (noC. diffor uninfected, wild type, andtcdR) with the NanoString Mouse Immunology panel modified to include probes targeting transcripts encoding mat...

Among 107 PCR-positive samples, 46 (43.0 %) had toxins detected by immunoassay and an additional 18 (16.8 %) had toxin detected by the cytotoxin assay yielding 64 (59.8 %) toxin-positive and 43 (40.2 %) toxin-negative samples. Overall, toxin-negative samples with C. difficile had 101–...

实时荧光定量PCR(quantitative real-time PCR,qPCR)是指在PCR反应体系中加入荧光基团,利用荧光信号积累实时监测整个PCR进程,*通过标准曲线对未知模板进行定量分析的方法。实时荧光定量PCR的化学原理包括探针类和非探针类两类,探针类是利用与靶细胞序列特异性杂交的探针来指示扩增产物的增加,非探针类是利用荧光染料或者特异...
