Anguillulina putrefaciens, Kühn, 1879.
Syn.: Tylenchus putrefaciens, Kühn; Trichina contorta, Botkin, 1883.
In 1883 Botkin (Pet. klin. Wochenschr., 1883) found a small Nematode, which was, however, entirely mistaken, in the material vomited by a Russian; this was not a species of Trichinella, but an Anguillulina living in onions which had already, in 1879, been described by Kühn as Tylenchus putrefaciens; the Nematodes got into the stomach with the onions, causing nausea and vomiting.
Family. Angiostomidæ, Braun, 1895.
