The page of that fruit only mentions bacteria and viruses only. It never mentioned prions.

Its usage section specifally says: Black Death would use this devil fruit ability to absorb and create a variety of disease-causing viruses and bacteria to infect his enemies in order to weaken them during battle or to cause them to die eventually. He could create rats made out of the viruses and bacteria and control them to move anywhere he wants them to.

There is also this statement: Black Death can not succumb to any symptoms of any diseases that are caused from bacteria and viruses despite making them from his body. - Once again implying that only viruses and bacteria are the domains of this fruit.
