Because different viruses may elicit similar symptoms, the disease phenotype can provide only limited, although important, information for disease diagnosis. More specific and reliable methods of virus identification are based on various properties of the virus. These properties and corresponding approaches include the following: pathogenicity (bioassays using indicator plants), transmissibility (vector transmission assays), architecture of virus particles (electron microscopy), presence of virus-specific structures in infected cells (electron microscopy), properties of the protein coat (immunological procedures), properties of viral nucleic (PCR amplification).
