Slang words describing human feces are often used to denote products of poor quality or that have absolutely no value whatsoever. A product that is substandard is sometimes derisively referred to as “crap” — or worse. Now, a company in Massachusetts is collecting fecal material into a “stool bank,” and selling the screened preparations to hospitals for $385 apiece. The material is later injected into sick patients’ digestive tracts infected with Clostridium difficile. These are difficult-to-treat bacterial infections that kill an estimated 14,000 people annually. The donated feces are obtained from healthy donors, who are paid $40 per donation. The average donation is screened and divided into four preparations, enough to treat four patients. In a clinical trial, the results from using donated fecal material were superior to using antibiotics.
