Are we going to have another “Black Plaque” from off the bones?
Not if we floss properly.
Bubonic plague from time to time shows up in New Mexico.
It’s speculated that it is spread by rats that eat pinion pine nuts and urinate on them. Humans pick up the nuts and eat them.
Not sure this is the actual vector, but the plague still exists in the real world. Different strain? Not sure.
A black plaque might form on your teeth if you don’t brush and floss regularly but it won’t come from Y. Pestis.
The transmission vector is insect/animal and from contact with active buboes and body fluids of an infected person.
Dry bones centuries old, no. It is possible to extract Y. Pestis DNA from bones of medieval plague victims but not the bacterium itself.
I believe the medical scientists say now that the plague is mostly transmitted by fleas (from the rats we always heard about).
Either way, these researchers are well advised to please be careful digging in a Black Death cemetery (not that it hasn’t been done before without spreading the disease, it has....but STILL......fleas are very tiny and hard to see and prevent from spreading...)
