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;... Continue Reading →
The process of mapping ancient Yersinia pestis (plague) strains along the central Asian mountain chain, or greater Himalayas continues. Up to now, most of the living ancient strains have been mapped in Tibet/western China and a few scattered other places (Cui et al, 2010). Russian scholars have a released data on mapped ancient strains of Yersinia... Continue Reading →
I have a weakness for good scientific graphics, especially zoonotic cycles. In his recent paper, Christos Lynteris looks at these diagrams with the eye of a visual anthropologist. He explains why zoonotic cycle diagrams work, and why they sometimes confer much more information that we intend (or want). Since these diagrams are intended for public... Continue Reading →
Initially, it seemed like just another, now annual, outbreak. Plague is endemic in Madagascar, producing about 400 infections per year. As of October 13, there were 684 cases infections with 57 deaths. Four days later (the weekend update), the case number jumped to 804 cases and 74 deaths for a 9.3% mortality rate and pneumonic plague reached 74%... Continue Reading →
I love this flourescent mircrograph by Brad Amos at LMP
by Michelle Ziegler Contagions: The Society for Historic Infectious Disease Studies has been given the opportunity of organizing three sessions at next year's International Congress for Medieval Studies. 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... Continue Reading →
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... Continue Reading →
by Michelle Ziegler Bruce Campbell. The Great Transition: Climate, Disease, and Society in the Late Medieval World. Cambridge University Press, 2016. When I first learned that Bruce Campbell was working on this book, I wondered if it would be the first grand synthesis of the new paradigm. Although there have been some very good regional...

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...
