Signs and symptoms of CDI range from mild diarrhea to severe life-threatening inflammation of the colon. [16]In adults, a clinical prediction rule found the best signs to be significant diarrhea ("new onset of more than three partially formed or watery stools per 24-hour period"), recent antibiotic exposure, abdominal pain, fever (up to 40.5 °C or 105 °F), and a distinctive foul odor to the ...
Clostridioides difficile (syn. Clostridium difficile) is a bacterium known for causing serious diarrheal infections, and may also cause colon cancer. [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 difficile, also known more commonly as C. diff, accounts for 10 to 20% of antibiotic-associated diarrhea cases, because the antibiotics administered for the treatment of certain disease processes such as inflammatory colitis also inadvertently kill a large portion of the gut flora, the normal flora that is usually present within the bowel.
Toxic megacolon in a patient with ulcerative colitis: The patient subsequently underwent a colectomy. A pathological specimen showing toxic megacolon The pathological process involves inflammation and damage to the colonic wall with unknown toxins breaking down the protective mucosal barrier and exposing the muscularis propria .

The condition is usually caused by Gram-positive enteric commensal bacteria of the gut (). Clostridioides difficile is a species of Gram-positive bacteria that commonly causes severe diarrhea and other intestinal diseases when competing bacteria are wiped out by antibiotics, causing pseudomembranous colitis, whereas Clostridium septicum is responsible for most cases of neutropenic enterocolitis.
The first use of FMT in western medicine was published in 1958 by Ben Eiseman and colleagues, a team of surgeons from Colorado, who treated four critically ill people with fulminant pseudomembranous colitis (before C. difficile was the known cause) using fecal enemas, which resulted in a rapid return to health. [55]
Hence, this leads to tumor necrosis factor α (TNF α) and proinflammatory interleukins being established as the major causative agents of pseudomembranous colitis (PMC) and antibiotic-associated diarrhea (AAD). [2] [3] [43] The involvement of toxin A and—most importantly—toxin B is the key element that determines the disease caused by C ...
The signs and symptoms of colitis are quite variable and dependent on the cause of the given colitis and factors that modify its course and severity. [2]Common symptoms of colitis may include: mild to severe abdominal pains and tenderness (depending on the stage of the disease), persistent hemorrhagic diarrhea with pus either present or absent in the stools, fecal incontinence, flatulence ...
