Testing of stool samples by real-time polymerase chain reaction is able to detect C. difficile about 93% of the time and when positive is incorrectly positive about 3% of the time. [54] This is more accurate than cytotoxigenic culture or cell cytotoxicity assay. [ 54 ]
A C. difficile infection is often suspected because of foul-smelling diarrhea, but this does not confirm if the patient has a CDI. To confirm a CDI, a cytotoxin assay detects the cell's toxin B (ToxB) cytotoxicity in the fecal eluate. The presence of C. difficile toxin is confirmed by the anti-toxin antibodies' neutralization of the cytotoxic ...

Fecal microbiota transplant (FMT), also known as a stool transplant, [2] is the process of transferring fecal bacteria and other microbes from a healthy individual into another individual. FMT is an effective treatment for Clostridioides difficile infection (CDI).
There are different plasmid sizes of C. difficile. The detected molecular weights range from 2.7x10 6 to 100x10 6, but plasmid sizes show no correlation with toxicity. In order to detect the toxin B level in C. difficile, clinicians extensively use cell culture assays derived from stool specimens from patients with PMC.
Fecal microbiota, sold under the brand name, Rebyota is used for the prevention of recurrence of Clostridioides difficile infection. [1] [4] The most commonly reported adverse reactions include abdominal pain, diarrhea, abdominal distention, flatulence, and nausea. [1] Fecal microbiota is prepared from stool donated by qualified individuals. [4]
OpenBiome distributes material to hospitals and clinics to support the treatment of C. difficile, the most common pathogen causing hospital-acquired infection in the U.S. [1] OpenBiome provides frozen preparations of screened and filtered human stool for use in fecal microbiota transplantation (FMT) therapies.
