Trichinosis being common in Germany at that time, A'irchow and Leuckart undertook its investigation, but mistook other nematodes of the intestine for the Trichina spiralis. In 1847 Leydy recognised that trichinosis occurred in American pigs. In 1860 Zenker found muscular and intestinal trichinosis on post- mortem examination of a girl who had been suspected of suffering from tyi)hoid fever, and a carefully conducted inquiry revealed the fact that
