of the C. difficile toxin gene by molecular methods such as polymerase chain reaction (PCR): Stool sample collection should occur as soon as possible after the onset of diarrhea. Rapid turnaround time for C. difficiletesting and reporting is essential and should be pre-arranged
Therefore, for surveillance purposes, an individual may be classified and captured as a new incident case if eight consecutive weeks have elapsed since their last C. difficile -positive test. CDI cases with a positive C. difficile stool specimen between 2 to 8 weeks of the last positive specimen are considered recurrent episodes.

Each laboratory regularly reports positive C. difficile test results to the local EIP site.
A negative test result for the C. difficile toxin gene likely indicates that the person's diarrhea and related symptoms are not due to toxin-producing C. difficile. Negative test results for both the bacteria and the toxin may mean that the diarrhea and other symptoms are being caused by something other than C.
C. diff spread can be stopped by washing your hands often and reminding those around you to wash their hands as well. Ask your visitors and health care providers to follow any Special Contact Precautions in place and to wash their hands before entering and when leaving the room.
Contact PrecautionsUse gloves and gown when entering patients' rooms and during patient care. Remove PPE and perform hand hygiene when exiting the room.Change gloves and gowns and perform hand hygiene when moving from one patient to another when patients are cohorted, and before leaving patient room.
If tests for C. difficile toxin gene and C. difficile toxin are positive, it is likely that the person's diarrhea and related symptoms are due to the presence of toxin-producing C. difficile.

difficile is confirmed through testing, nurses should constantly assess patients for signs of complications. This includes checking the abdomen for distention or tenderness, evaluating stool for the presence of blood, and monitoring the patient for fever. Nursing care should focus on hydration and skin integrity.
Clean their hands with soap and water or an alcohol-based hand rub before and after caring for every patient. This can prevent C. diff and other germs from being passed from one patient to another on their hands. Carefully clean hospital rooms and medical equipment that have been used for patients with C.
contact precautionsUse contact precautions for patients with known or suspected CDI: Place these patients in private rooms. If private rooms are not available, they can be placed in rooms (cohorted) with other CDI patients. Wear gloves and a gown when entering CDI patient rooms and during their care.
Clearly, glove use is the precaution proven to be most effective in preventing the transmission of C. difficile during care of a patient with CDI [22]. After removal of gloves worn during care of patients with CDI, we prefer handwashing with soap and water.
Health-care workers should wear gloves and aprons when providing care for patients with C. difficile and should discard them immediately after they have been worn for a patient-care activity. Hand hygiene must then be performed.
The most common signs and symptoms of mild to moderate C. difficile infection are: Watery diarrhea three or more times a day for more than one day. Mild abdominal cramping and tenderness.
C. diff is a spore-forming, Gram-positive anaerobic bacillus that produces two exotoxins: toxin A and toxin B. It is a common. cause of antibiotic-associated diarrhea (AAD). It accounts for 15 to 25% of all episodes of AAD.
Molecular tests: FDA-approved PCR assays, which test for the gene encoding toxin B, are same-day tests that are highly sensitive and specific for the presence of a toxin-producing C. diff organism. Molecular assays can be positive for C. diff in individuals who are asymptomatic.
C. diff toxin is very unstable. The toxin degrades at room temperature and might be undetectable within two hours after collection of a stool specimen. False-negative results occur when specimens are not promptly tested or kept refrigerated until testing can be done.
Any surface, device, or material (such as commodes, bathtubs, and electronic rectal thermometers) that becomes contaminated with feces could serve as a reservoir for the C. diff spores.
After tremendous increases during 2000 and 2011, CDI rates plateaued at historic highs and have since begun to show some decline. In 2011, an estimated 476,400 CDIs in the United States were reported; C. diff accounted for 12.1% of all healthcare-associated infections. Between 2011-2017, nucleic acid amplification tests (NAAT) increased in use. After adjusting for the use of NAAT, the estimated CDI burden decreased by 24% during 2011-2017 with 365,200 cases reported in 2017. The decrease was driven by a 36% decrease in cases of healthcare-associated CDI, while community-associated CDI was unchanged. After adjusting for NAAT use, hospitalized cases of CDI decreased by 24%. There were no changes in estimates of first recurrences and in-hospital deaths during 2011-2017. We have also seen a decline in ribotype 027, an epidemic strain of C. diff that emerged in the 2000s. This decline in ribotype 027 might be partly driven by a decreased use of fluoroquinolone in U.S. hospitals. Continued efforts to improve adherence to recommended infection prevention measures and implement diagnostic and antibiotic stewardship in both inpatient and outpatient settings will further reduce CDI.
In about 20% of patients, CDI will resolve within two to three days of discontinuing the antibiotic to which the patient was previously exposed. The infection can usually be treated with an appropriate course (about 10 days) of antibiotics, including oral vancomycin or fidaxomicin.
If the patient is positive for CDI: Continue isolation and contact precautions. Use antibiotics judiciously. Clean room surfaces thoroughly on a daily basis while treating a patient with C. diff and upon patient discharge or transfer using an EPA-approved spore-killing disinfectant.
difficile molecular assay (e.g. PCR) of a stool specimen from a resident of the surveillance catchment area who is at least 1 year old. Cases with a C. difficile -positive stool specimen greater than 8 weeks after the last positive specimen are considered a new case with an incident stool specimen. Therefore, for surveillance purposes, an individual may be classified and captured as a new incident case if eight consecutive weeks have elapsed since their last C. difficile -positive test.
CDI cases are identified based on reports of positive C. difficile toxin assay or C. difficile nucleic acid amplification assay from all clinical, reference, and commercial laboratories that serve the population in the surveillance catchment areas. Each laboratory regularly provides line listings of positive C. difficile test results to the local EIP site. The line listings include the patient name and local laboratory identifier, date of specimen collection, as well as any additional available information (e.g. address, date of birth, age, sex, location of stool collection). Information on additional positive specimens from the same patient is recorded for the purpose of ascertaining and tracking recurrent or duplicate episodes, as well as new cases (i.e., greater than eight weeks after the last positive C. difficile specimen).
Overview. Clostridioides difficile infection (CDI) is the leading cause of antibiotic-associated diarrhea and one of the most common healthcare-associated infections in the United States. The Clostridioides difficile infection surveillance program is an active population- and laboratory-based surveillance system conducted through CDC’s Emerging ...
When a person treated for antibiotic-associated diarrhea or colitis relapses and symptoms reoccur, C. difficile testing may be ordered to confirm the presence of the toxin.
diff for short), the genes associated with toxin production, and its toxins are used to help diagnose diarrhea and other conditions and complications caused by toxin-producing C. difficile. (See the "What is being tested?".
Normal bacterial flora that are susceptible to the antibiotic are eliminated from the digestive tract, while C. difficile that are resistant to the antibiotic remain and begin to overgrow, or new types (strains) of C. difficile are acquired. C. difficile usually produced two toxins: toxin A and toxin B. The resulting combination of decreased normal ...
Dead tissue, fibrin, and numerous white blood cells can form a lining over the surface of the inflamed bowel (a pseudomembrane), a condition that is referred to as pseudomembranous colitis. C. difficile infection is the most common cause of diarrhea in people who develop diarrheal symptoms while hospitalized.
Clostridium difficile (commonly called C. difficile or C. diff) is a type of bacteria that is associated with diarrhea resulting from antibiotic use. C. difficile testing and C. difficile toxin tests identify the presence of these bacteria, genes associated with toxin production, and/or detect the toxins produced by them.
C. difficile usually produced two toxins: toxin A and toxin B . The resulting combination of decreased normal flora, overgrowth of C. difficile, and toxin production can damage the lining of the lower portion of the digestive tract (colon, bowel) and lead to severe inflammation of the colon and prolonged diarrhea.
Testing may be ordered for outpatients when someone develops these symptoms within 6-8 weeks after taking antibiotics, several days after chemotherapy, or when a person has a chronic digestive tract disorder that a healthcare practitioner suspects is being worsened by a C. difficile infection.
By the fifth day, his diarrhea was almost gone and Al was ready to go back to work. Four days later the diarrhea returned. It was as bad as it had been in the beginning. This time, Al’s doctor started him on Vanco (the other antibiotic taken by Jeannie) four times per day.
After the transplant Al felt fine. Naturally, he worried that C. diff might come back. When he saw the gastrointestinal doctor three weeks later, he had no diarrhea, the longest time he had been without symptoms since the root canal. Three months after the stool transplant, Al was feeling great and working full time.
This time, the diarrhea came back two weeks after he stopped taking Vanco.
The diarrhea was severe, occurring up to 10 times per day. He called his doctor who tested his stools for C. diff. The result was positive. Treatment was started with 10 days of Flagyl (one of the same antibiotics taken by Jeannie) four times per day. By the fifth day, his diarrhea was almost gone and Al was ready to go back to work.
The normal colonic flora provides a protective barrier against C. diff, other harmful bacteria, and viruses. That’s why nearly every patient who gets C. diff has taken an antibiotic before the diarrhea starts. But Al’s barrier was so low that the C. diff kept coming back after he stopped the Vanco.
Al’s wife was healthy, with no diarrhea and no recent antibiotics. The plan was for her to come in with Al on the day of his colonoscopy, and to “donate” a stool sample that would be used to reseed his colon.
Some patients are afraid to try a stool transplant because it seems “gross” or “yucky.”. But in hundreds if not thousands of patients worldwide the procedure is safe and very effective.
difficile infection and look for alternative causes of your symptoms, your doctor may examine the inside of your colon. This test (flexible sigmoidoscopy or colonoscopy) involves inserting a flexible tube with a small camera on one end into your colon to look for areas ...
If your doctor is concerned about possible complications of C. difficile, he or she may order an abdominal X-ray or a computerized tomography (CT) scan, which provides images of your colon. The scan can detect the presence of complications such as thickening of the colon wall, expansion of the bowel or, more rarely, a hole (perforation) in the lining of your colon.
Several main types of lab tests exist, and they include: Polymerase chain reaction. This sensitive molecular test can rapidly detect the C. difficile toxin B gene in a stool sample and is highly accurate. GDH/EIA. Some hospitals use a glutamate dehydrogenase (GDH) test in conjunction with an enzyme immunoassay (EIA) test.
difficile is another antibiotic. These antibiotics keep C. difficile from growing, which in turn treats diarrhea and other complications. Your doctor may prescribe vancomycin ( Vancocin HCL, Firvanq) or fidaxomicin (Dificid).
Other good choices are saltine crackers, bananas, soup and boiled vegetables. If you aren't hungry, you may need a liquid diet at first. After your diarrhea clears up, you may have temporary difficulty digesting milk and milk-based products. By Mayo Clinic Staff. C. difficile infection care at Mayo Clinic.
Are older than 65. Are taking other antibiotics for a different condition while being treated with antibiotics for C. difficile infection. Have a severe underlying medical disorder, such as chronic kidney failure, inflammatory bowel disease or chronic liver disease. Treatment for recurrent disease may include:
This type of test is sensitive, but it is less widely available, is more cumbersome to do and requires 24 to 48 hours for test results. It's typically used in research settings.
