A while ago I took an interest in Yersinia pestis, the infamous microorganism that caused the ‘black death’ in Europe in the past and still causes a lot of misery in some places in the world today. One of the things that caught my eye while I was looking into some of the historical aspects of the black death, was if Y. pestis was actually getting improper credit for causing the entire mess and that something else might have caused the black death. While my curiosity was piqued, I sadly didn’t get the time to investigate the issue in enough depth to make any kind of comment. Thankfully, Tara has recently done a series on Y. pestis that more or less looks at the entire issue and sums up (and refutes) the arguments against Y. pestis quite soundly. It comes in four parts (First, second, third and fourth) as well for even more fun!
