摘要：
Glutamate dehydrogenase (GDH) is popular as a preliminary test for the detection of Clostridium difficile. Recent work has suggested that GDH sensitivity may vary according to ribotype and may be lower for ribotypes 002, 027, and 106 compared with polymerase chain reaction (PCR). We investigated this effect using a dilution series of 64 isolates tested by GDH and Cepheid GeneXpert PCR. PCR was significantly more sensitive than GDH overall; however, there was no difference in detection according to specific ribotype. Crown Copyright (c) 2011 Published by Elsevier Inc.
