Visualization by immune electron microscopy of viruses associated with acute respiratory disease.

A sensitive and rapid method for detecting adenovirus and influenza viruses has been demonstrated by using both the direct and indirect immune electron microscopy technique. The indirect method was from 4 to over 32 times more sensitive than the direct method. The technique appears to have the sensitivity approaching tissue culture methods, but is much more rapid, requires less laboratory support personnel and space, and should lend itself to detection of noncytologic agents. These data suggest a new role for the electron microscope in diagnostic virology.
