The aim of this research is to determine which parasites were present in a mediaeval latrine from the old city of Jerusalem. This latrine contains fragments of pottery from the Middle East and also from Italy, suggesting links of some kind with Europe. Excavation identified two separate entry chutes emptying in a shared cesspool. Radiocarbon dating and pottery analysis is compatible with a date of use in the late fifteenth century and early sixteenth century. Twelve coprolites (preserved stool) and mixed cesspool sediment were analysed with light microscopy and enzyme-linked immunosorbent assay (ELISA). Six species of intestinal parasites were identified. These were the helminths Ascaris lumbricoides (roundworm), Trichuris trichiura (whipworm), Taenia sp. (beef/pork/asiatic tapeworm) Diphyllobothrium sp. (fish tapeworm), and two protozoa that can cause dysentery (Entamoeba histolytica and Giardia duodenalis). While roundworm and whipworm were found in every sample, the other parasite species were present in only one or two samples each, suggesting that only a minority of those using the latrine were infected with those species. The role of Jerusalem as a site for long distance trade, migration or pilgrimage is considered when interpreting the Italian pottery and the parasites present, especially E. histolytica and Diphyllobothrium sp.
