I have read several papers about FMT that cite using a cocktail for Ampicillin/Neomycin, however, the product company and number are never included in these manuscripts. I was able to find a few citations that use sigma products (Ampicillin sodium salt, A0166 and Neomycin trisulfate salt hydrate N6910) but these are for cell culture use and not animal research. Does anyone have a suggestion for vet approved solutions?
