Up until a couple of years ago, i wasof the school that 'black death' and 'bubonic plague' were two different things. But they have sequenced dna from black death victims, and its clearly Yersinia pestis, although a different strain from what we see today.There still isn't any consensus as to what it was? And for that matter, whether or not it was the same thing every time it hit. Yersinia pestis does not adequately explain a number of the systems of the different plagues.
So, in theory, it could certainly have been. It just depends on what school of thought on which you want to base your timeline on and which plague you want to target. It would be difficult to get rid of all three though...
Certainly, there have been other plagues of other diseases, but it does look like the black death was Y.pestis.
