Did Human Survivorship Improve Following The Black Death Epidemic?

Lawrence LeBlond for redOrbit.com - Your Universe Online Killing tens of millions of Europeans during the mid-1300s, the medieval Black Death plague was one of the worst disease outbreaks humans have ever faced. But as devastating as the disease was, it may have helped human survival over the course of many generations, according to new research from Sharon DeWitte, PhD, Assistant Professor of Anthropology and Biology at the University of South Carolina. Previous studies have shown that...

Pathogen Responsible For Two Historical Plagues Could Reemerge

[ Watch the Video: Pathogen Behind Ancient Plagues Could Come Back Someday ] Brett Smith for redOrbit.com - Your Universe Online Both the Plague of Justinian in 541 and Black Death some 800 years later were responsible for widespread fatalities across Europe. Now, new research in The Lancet Infectious Diseases journal has found that both pandemics were caused by different strains of the same pathogen. The international team of study authors also concluded that a new strain of plague...

Scientists Unravel The Role Of A Pathogen Molecule

Helmholtz Centre for Infection Research Braunschweig have now discovered what makes a specific strain of Yersinia pseudotuberculosis–one of the main instigators for these infections–so dangerous: the bacteria produce a molecule called CNFy that facilitates the infection process for them. It changes the host cells in a manner that enables the injection apparatus of Yersinia, which injects toxins into the cells, to work more efficiently. This strengthens the infection and leads to...

Among medical mysteries baffling many infectious disease experts is exactly how the deadly pneumonic plague bacterium, Yersinia pestis, goes undetected in the first few day of lung infection, often until it's too late for medical treatment. New research from the University of North Carolina at Chapel Hill School of Medicine has opened a door to the answer. Researchers led by William E. Goldman, PhD, professor and chair of microbiology and immunology at the University of North Carolina at...

14th Century Plague Lives On Via New Strain
2011-08-30 10:17:00

  According to a study published Tuesday, a less virulent version of the 14th century's Black Death plague is still present today. DNA testing on the skeletons of plague victims unearthed in a medieval London mass grave revealed part of the same gene sequence as the modern bubonic plague. "At least this part of the genetic information has barely changed in the past 600 years" said Johannes Krause, one of the authors of the study published in the Proceedings of the National...

HARRISBURG, Pa., July 29, 2011 /PRNewswire-USNewswire/ -- The Pennsylvania departments of Health and Agriculture and the Allegheny County Health Department are advising the public of the possible health risks associated with products, specifically glass-bottled milk, from Brunton Dairy in Aliquippa, Beaver County. Since June 15, five individuals - three young children and two older adults - developed diarrhea and other symptoms caused by bacteria called Yersinia enterocolitica. All five...

A new study tracking the DNA signature of the plague has found that the deadly disease first broke out in China more than 2,600 years ago before making its way to Europe via Central Asia's "Silk Road" trade route. The findings prove many suspicions about the long-believed Chinese origins of the plague, which killed nearly a third of Europeans during the Middle Ages. Scientists from around the world sequenced 17 strains of Y. pestis, connecting them as pathogens that mutated from a common...

Black Death, one of the deadliest pandemics in human history, has been confirmed by anthropologists to have been caused by a germ called Yersinia pestis. Researchers studied tooth and bone samples from 76 skeletons discovered in "plague pits" in France, Germany, Italy and the Netherlands and found DNA evidence that Y. pestis was to blame for the plague that wiped out nearly a third of Europe's population during the Middle Ages. It was believed for more than a century that Y. pestis was the...
