Clostridioides difficile infection [5] (CDI or C-diff), also known as Clostridium difficile infection, is a symptomatic infection due to the spore-forming bacterium Clostridioides difficile. [6] Symptoms include watery diarrhea , fever, nausea, and abdominal pain . [ 1 ]
[4] [5] It is known also as C. difficile, or C. diff (/ s iː d ɪ f /), and is a Gram-positive species of spore-forming bacteria. [6] Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the ...
In order to purify toxin B from C. difficile cell cultures, brain heart infusion broth is used because it promotes the synthesis of toxin B. [11] The filtration method facilitates purification of toxin B from the supernatant of C. difficile. The toxin concentration of the supernatant is proportional to the organism cell count.
The toxins are the main virulence factors produced by the gram positive, anaerobic, [2] Clostridioides difficile bacteria. The toxins function by damaging the intestinal mucosa and cause the symptoms of C. difficile infection, including pseudomembranous colitis. TcdA is one of the largest bacterial toxins known.

Heterophile also can mean that it is an antibody that reacts with antigens other than the antigen that stimulated it (an antibody that crossreacts). [citation needed] A 20% suspension of horse red cells is used in an isotonic 3–8% sodium citrate formulation. One drop of the patient's serum to be tested is mixed on an opal glass slide with one ...
Stool antigen detection tests have helped to overcome some of the limitations of stool microscopy. Antigen detection tests are easy to use, but they have variable sensitivity and specificity, especially in low-endemic areas. [7] Polymerase chain reaction (PCR) is considered the gold standard for diagnosis but remains underutilized. [7] [18]
