Rabies Virus Can Be Directly Detected in Brain Tissue Using

Question

Rabies virus can be directly detected in brain tissue using a(n) ________ assay.
A) viral neutralization
B) direct fluorescent antibody
C) immunodiffusion precipitation
D) viral hemagglutination inhibition
E) immunoblot

Accepted Answer

Direct fluorescent antibody assay is the most sensitive and specific method for detecting rabies virus in brain tissue.
