OpenBiome is a nonprofit 501(c)(3) organization. They have created a stool bank with fecal microbiota transplants from screened donors, to be used for treatment of recurrent C.difficile infection.
From their website:
We work with clinicians to make FMT easier, cheaper, safer and more widely available. We do so by providing hospitals with screened, filtered, and frozen material ready for clinical use. This service eliminates the time, staff, protocols, and facilities needed to screen and prepare material from new donors for each treatment. With OpenBiome, all that’s needed to deliver FMT is a doctor and an endoscope.
