The Virginia opossum (a marsupial, unlike the other mammals named above, which are all eutherians/placental), has a lower internal body temperature than the rabies virus prefers and therefore is resistant but not immune to rabies. [47]
Opossums are not considered dangerous to humans. [56] Though their open-mouth hiss when frightened is often mistaken as rabid behavior, opossums are naturally resistant to rabies due to their low body temperature. Opossums can however host parasites and carry diseases such as tuberculosis, leptospirosis, and tularemia, among others. [57]

3D still showing rabies virus structure. Rhabdoviruses have helical symmetry, so their infectious particles are approximately cylindrical in shape. They are characterized by an extremely broad host spectrum ranging from plants [citation needed] to insects [citation needed] and mammals; human-infecting viruses more commonly have icosahedral symmetry and take shapes approximating regular polyhedra.
