Stool: negative C&S and positive C. difftoxin. CT showed air fluid levels throughout the colon with diffuse colonic submucosal edema. The appendix was thick-walled, dilated up to 13 mm distally, with adjacent fat stranding. CT of her abdomen three days after admission showed that the ...
“Currently, cross-regional strains are negative for the C difficile toxin (CDT). The isolation rate of CDT-producing strains in Japan has been relatively low (0 to 6.8%). It could be a concern if a CDT-positive strain were to emerge as a cross-regional strain. Hence, the implementation...
The C.DIFF CHEKTM is an enzyme immunoassay for use as a screening test to detect C. difficile antigen, glutamate dehydogenase, in fecal samples. The goals of this evaluation were to determine the sensitivity, specificity, positive predictive value, negative predictive value and correlation of ...
Fidaxomicin (Fdx) is widely used to treat Clostridioides difficile (Cdiff) infections, but the molecular basis of its narrow-spectrum activity in the human gut microbiome remains unknown. Cdiff infections are a leading cause of nosocomial deaths1. Fidaxo

All samples were confirmed negative for the binary toxin gene ctdB and 11% of the isolates were positive for ctdA gene. Many studies have used NAAT to study CDI and many of them reported false positive results for colonized patients without disease (Fang et al., 2017). Interestingly, one ...

Using a 2-step approach to diagnosing CDI starting with a glutamate dehydrogenase toxin A/B enzyme immunoassay for toxin A or B and then moving to a PCR assay to detect toxigenic C difficile might be a helpful strategy to reduce detection and unnecessary treatment of C difficile colonization [...
“Last year a study was published that turned this on its head and appeared to prove that Clostridium difficilestrainsproducing Toxin A alone were innocuous, and that only Toxin B was essential for disease. This had significant implications — already we have seen a move within the diagnostics i...
