摘要
We describe a novel ultrasensitive cell-based immunocytotoxicity assay for detecting Clostridium difficile toxin A and B. The assay is simple to perform with a turnaround time of approximately 3 h. It is particularly sensitive in detecting TcdA at a level less then 1 pg/ml. Using this assay, we were able to detect the presence of C, difficile toxins in the fecal and serum specimens of experimentally infected piglets.
