An early theory on the causes of food poisoning involved ptomaines (from Greek ptōma, "fall, fallen body, corpse"), alkaloids found in decaying animal and vegetable matter. While some alkaloids do cause poisoning, the discovery of bacteria left the ptomaine theory obsolete and the word ptomaine is no longer used scientifically.

最後だけ言えば「バクテリアの発見以後プトマイン説は時代遅れとなり
科学の用語としては用いられない」
