instruments as complex as an electron microscope. Samples obtained from patients may
be viewed directly under the light microscope, and can often rapidly lead to
identification. Microscopy is often also used in conjunction with biochemical staining
techniques, and can be made exquisitely specific when used in combination with
antibody based techniques. For example, the use of antibodies made artificially
fluorescent (fluorescently labeled antibodies) can be directed to bind to and identify a
specific antigens present on a pathogen. A fluorescence microscope is then used to detect
fluorescently labeled antibodies bound to internalized antigens within clinical samples or
cultured cells. This technique is especially useful in the diagnosis of viral diseases, where
the light microscope is incapable of identifying a virus directly.
