It was previously reported that paleoparasitological clues for
parasites infecting humans could be found in the feces of mummies of
the Joseon Dynasty (1392-1910) in the Republic of Korea. Here, we
report the presence of trematode eggs, including Clonorchis sinensis,
Metagonimus yokogawai, and Gymnophalloides seoi (a human parasite
known in Korea since 1993) in the feces of a recently excavated female
mummy in Hadong, Republic of Korea. This is the first report of the
discovery of a G. seoi infection in a human mummy. Since Hadong is
currently not an endemic area for G. seoi, we speculate that the
parasite might have occurred frequently along coastal areas of the
Korean peninsula several hundred years ago and that the endemic areas
contracted to, more or less, restricted regions since that time.
