[S2] The spread and evolution of ancient infectious diseases

The Scientific Studies on Ancient Parasite Infection of East Asia by Microscopic and Genetic Researches

Only about 100 years ago, parasite disease was one of the most prevalent diseases worldwide. The recent development of paleo-parasitology using archaeological samples can provide a wealth of information, making a scientific basis for understanding of ancient parasitism in history. Although East Asia is a region with a long history, the academic tradition of the research on the ancient parasitism was very weak. In recent years, however, interdisciplinary studies successfully revealed how the people of the area were affected by parasite infection in the past; and further analyzed even the ancient parasite genes. Actually, through the microscopic examinations of the mummy coprolites, we estimated the infection prevalence of each parasite spp. in pre-modern East Asia. More interestingly, using the ancient DNA (aDNA) analysis, we also got the genetic information of the ancient parasites prevalent in this area. To date, we sequenced Ascaris, Trichuris, Clonorchis, and Paragonimus aDNA; and by the analysis of the accumulated genetic information, we gained scientific evidences for understanding the genetic traits of ancient parasites in the historical East Asia. By the approaches, we know how the pre-modern parasitism in here differs from now and how their genetic characteristics have changed over the years.

Our new paper is out in Anthropological Science

In paleoparasitology, which is the study of ancient parasite species, parasite egg remnants in archaeological samples are examined by microscopic or molecular analysis. The parasitological information thus obtained can inform speculation about the parasite-infection patterns that prevailed in ancient societies. The current analysis of ancient feces removed from Joseon period mummies adds six new paleoparasitological outcomes to the existing pool of mummy parasitism data already maintained in South Korea. The current microscopic examination revealed the ancient parasite eggs of Trichuris, Clonorchis, Paragonimus, Ascaris, and Taenia in the Joseon mummy feces. When the updated Joseon data were compared with the 20th-century National Survey statistics of South Korea, clear differences could be observed between ancient and modern parasite infection rates. These results will yield invaluable insights -unobtainable by conventional historical investigation-that contribute to the knowledge base on the parasitism of pre-industrial East Asian societies.
