Lazarus does not have the plague!

I get it. We would all like to have more illustrations of the plague. It is hard to fathom how a horrific event like the Black Death has left so few bonafide illustrations. Misidentified illustrations do not solve the problem; they compound the confusion. Three images commonly used to illustrate the Black Death have been proven misidentifications;...

CFP: Contagions sessions at the International Congress for Medieval Studies 2018

This is the equivalent of a full day at the Congress. The Congress will be held from May 10 to May 13, 2018, at Western Michigan University in Kalamazoo...

The Microbial Anthropocene

Over the last decade or so, geologists and ecologists have begun to talk about planet earth entering a new geologic period called the Anthropocene, defined as the period when humans became the driving force of change on planet Earth. Debates continue on when the Anthropocene begins; sometime in the late 18th century when the industrial...

Medieval Historians Taking Genomics into Account

At the International Congress on Medieval Studies at Kalamazoo (Kzoo) last month, I couldn't help feeling that we have reached a turning point. I went to four sessions that engaged in genomics, human and/or bacterial, in some way. Granted, these are a tiny proportion of the 500+ sessions offered, but I have learned that if you...

Pregnancy, ‘coffin birth’, and the Black Death

by Michelle Ziegler The Genoese have always been central in the legend of the start of the Black Death, by their own claim, linking a siege of the Genoese at Kaffa to the spread of the epidemic in the Mediterranean. Last month the first confirmed plague graves in the region of Genoa were reported by...

Enjoy 3 hours of plague talks! Introduction-Plague in diachronic and Interdisciplinary perspective by...

War as a Driver in Tuberculosis Evolution

by Michelle Ziegler Russia has been all over the news lately. Beyond our recent election, increased Russian activity on the world stage has public health consequences for Europe and farther afield. It has been known for a long time that post-Soviet Russia had and continues to have serious public health problems. One of their particular...

Evolutionary Clues in 17th-Century Smallpox Genome

By Michelle Ziegler Smallpox is one of those diseases long believed to have an ancient pedigree, the suspected culprit of legendary epidemics. Yet, so far, smallpox hasn't made a big impression in ancient DNA surveys. If it was truly endemic throughout the Old World before 1492, so much so that it pops up in the...

Plague in 6th century Aschheim and Altenerding, Bavaria

Since I last wrote about Bavaria, the aDNA centers have been busy. With the accepted manuscript of the second new paper available this past week, its time for an update. The fourth paper on Aschheim not only confirmed the first three, but it also produced the first full genome of Yersinia pestis for the Plague...
