All what's needed is the patient making their own, home-made goat kefir (if they're not terribly allergic to dairy -- although even dairy allergies are a para-symptom of wheat allergy in reality). Kefir's 43 different bacteria and yeasts can kill CDiff, and it's being shown to do so in research (Minnesota university professor/doctor tried it recently too). But the kefir must be home-made (bottled ones don't include the full spectrum of bacteria/yeasts because of bottling regulations regarding alcohol the yeasts create), it must be from goat, sheep or buffalo milk (for less casein irritation, as the A2 casein is more compatible with humans), and it must be fermented for 24 hours (to minimize the amount of lactose ingested). Two-three cups a day of kefir (with a few berries in it, maybe with some pine and walnut nuts, also maybe with some raw, unfiltered and local honey too), and CDiff should be back in check within 3-4 days. No need for antibiotics, for pill probiotics, or doctors for that matter.
