A 22-year-old volunteer worker at a wildlife refuge is admitted
to the emergency room with agitation, disorientation, seizures, and
pain on swallowing. Physical examination reveals a partially healed
animal bite on his forearm. The animal which gave him this bite, a
raccoon, died several days ago, having shown similar symptoms.
Samples of brain tissue from the deceased animal reveal the
presence of Negri bodies (inclusion bodies) and viral antigens are
found in serum samples from the patient. Reverse transcriptase
polymerase chain reaction (PCR) on a skin biopsy from the patient
(saliva may also be used) confirmed the presence of viral antigen
from a bullet-shaped RNA-containing virus.

diagnosis?
