How serious is c-diff?

Can be very serious: C. Difficile, when pathologic, is a bacterial infection and as such warrants specialized antibiotic treatment with documentation of eradication following such appropriate therapy. That being said, a special probiotic (florastor = sacchromyces boulardes) can help inhibit growth of c.Diff, can help reduce recurrence in at risk populations, and may possibly prophylax against c.Diff infection.

Serious enough: Depending on the strain type some may end up dying from this or require surgical emoval of the large bowel to survive. In some cases it is a relapsing condition which could just be pesky outpatient issue but for the sick and elderly who cannot get rid of it and keep relapsing --- readmission can pose other risks.
