Question about C-diff

"How is C. difficile-associated disease usually treated? In 23% of patients, C. difficile-associated disease will resolve within 2-3 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 metronidazole or vancomycin (administered orally). After treatment, repeat C. difficile testing is not recommended if the patients’ symptoms have resolved, as patients may remain colonized."

Maybe she's thinking that the patient will remain colonized even though they are not symptomatic?

Not sure the answer to your question but I was just thinking that the understanding I have of C. diff is that we all have it in our GI tract. The problem with C. diff comes after being exposed to high dosages of antibiotics.... If this the case, wouldn't we all be positive for C. diff? Maybe a diagnosis is made by a count.. Not sure.

We do have C. diff in our G.I. but the antibiotics will disturb the normal flora causing the microorganisms to release the toxins (A/B), and that is how patients become positive when they are found in the stool. Patients will have elevated white count and diarrhea, and most often it is diagnosed via sigmoidoscopy or colonoscopy where they will find pseudomembranes which are characteristics of colitis.
