Which infectious agent is the most resistant to sterilization?

bacteria
virus
fungi
prion
The smaller the agent, the more dif­fi­cult it is to destroy it. Prions are quite re­sis­tant to pro­teas­es, heat, ra­di­a­tion, and formalin treat­ments. 134°C (274°F) for 18 minutes in a pres­sur­ized steam au­to­clave may not be enough to de­ac­ti­vate the agent of disease. Prions may last for decades in the en­vi­ron­men­t.
