Intestinal parasites in the Neolithic population who built Stonehenge (Durrington Walls, 2500 BCE).

Parasitology 2022 Jul 20;149(8):1027-1033. Epub 2022 May 20.

School of History, Classics and Archaeology, Newcastle University, Newcastle upon Tyne NE1 7RU, UK.

Durrington Walls was a large Neolithic settlement in Britain dating around 2500 BCE, located very close to Stonehenge and likely to be the campsite where its builders lived during its main stage of construction. Nineteen coprolites recovered from a midden and associated pits at Durrington Walls were analysed for intestinal parasite eggs using digital light microscopy. Five (26%) contained helminth eggs, 1 with those of fish tapeworm (likely ) and 4 with those of capillariid nematodes. Read More

Even though the cetacean tapeworm Diphyllobothrium stemmacephalum occurs in both cold and warm waters, human infections and final host occurrences have been confined to temperate areas in and near Japan. We recently obtained a strobila of this cestode that was excreted from a harbor porpoise accidentally caught offshore of Hokkaido of northern Japan. Genetic analysis of 28S rDNA and cox1 genes confirmed that the cestode was D. Read More

Yale J Biol Med 2021 06 30;94(2):297-309. Epub 2021 Jun 30.

Faculty of Medicine and Health Sciences, School of Veterinary Medicine and Science, University of Nottingham, UK.

Fish-borne parasites have been part of the global landscape of food-borne zoonotic diseases for many decades and are often endemic in certain regions of the world. The past 20 years or so have seen the expansion of the range of fish-borne parasitic zoonoses to new geographic regions leading to a substantial public health burden. In this article, we summarize current knowledge about the biology, epidemiology, clinical characteristics, diagnosis, treatment and control of selected fish-borne helminthic diseases caused by parasitic roundworm (), tapeworm (), and fluke ().
