'Modern Plague' Evidence from Ancient Mummies

A new analysis of mummies has revealed that a tiny-wormlike parasite, Schistosoma mansoni that plagues people worldwide, also infected ancient Africans.

The resulting disease from the worm, called schistosomiasis, is not generally lethal. But it can cause anemia, impair internal organs, damage growth and cognitive development in children, and lead to a general chronic weakening of its human hosts.

History of a 'Modern' Plague Highlighted by Mummies
The age-old irrigation techniques may have boosted the plague of schistosomiasis, mummies from along the Nile are revealing.

"Before this study, it was always assumed that S. mansoni was a product of modern urbanization," the National Geographic News quoted study co-author George Armelagos, an anthropologist at Emory University in Atlanta, as saying.

Since the discovery of parasite eggs on mummies in the 1920s, scientists had suspected that the Nubians might have been infected by schistosomiasis. But researchers generally assumed that the disease in Nubians had been caused by S. haematobium, a close cousin of S. mansoni.

Campbell Hibbs, study first author, and colleagues examined hundreds of naturally mummified Nubian mummies at Emory.

Vaccine To Fight Naturally Occurring Plague And Bioterrorism Too
US scientists could be closer to developing a vaccine that fights both the naturally plague and the bacteria that is sought to be used by terrorists for mass slaughter.

An analysis of the mummified skin revealed traces of proteins belonging to S. mansoni-the first proof that the ancient Nubians, or any ancient civilization, were afflicted by schistosomiasis.

The research will be published in the American Journal of Physical Anthropology this month.
