The Case of the Missing Worms

Research work may be glamorous, but… this study is evidence that sometimes it’s not easy:

Hepaticoliasis: a Frequent and Sometimes Fatal Verminous Infestation of the Livers of Rats and Other Rodents,” F.D. Weidman, Journal of Parasitology, vol. 12, no. 1, 1925. pp. 19–25. [AIR 15:4] (Thanks to investigator Wendy Cooper for bringing this to our attention.) Weidman supplies details: “This second rat died in six months and two filariform worms were found in its liver but no ova. Before the writer could determine their structural details they were lost, being eaten by cockroaches during a short absence from the laboratory room, but is believed that they were adult male Hepaticola.”
