There are a number of clinical situations where viral diagnosis may be particularly helpful. These include: Viral diseases in which there are important public health considerations (e.g., influenza and arbovirus…
Viral diagnosis by direct or indirect visualization can be achieved by using light or electron microscopy and relies on the identification of viruses based on typical morphological characteristics. Noncultivable viruses…
The presence of viral antigens in clinical specimens, such as nasopharyngeal aspirates, fecal specimens, vesicle fluids, tissue specimens, as well as serum samples can be demonstrated by antigen detection assays.…
The detection of newly developed, virus-specific antibody or the detection of a rise in titer of preexisting antibody is essential in viral analysis and is without doubt one of the…
Some viruses similar to widespread respiratory viruses (the influenza and parainfluenza viruses) and several other different viruses, mumps virus and Newcastle illness virus replicate in cell cultures however often don’t…
