In this study,
Ascaris
DNA was extracted and sequenced from a medieval archaeological sample in Korea. While
Ascaris eggs were confirmed to be of human origin by archaeological evidence, it was not possible to pinpoint the exact species due to close genetic relationships among them. Despite this shortcoming, this is the first
Ascaris ancient DNA (aDNA) report from a medieval Asian country and thus will expand the scope of
Ascaris aDNA research.
