Morphological and virological studies in six autopsies of children with adenovirus pneumonia.
Pulmonary lesions compatible with adenovirus infection were detected by gross and microscopic examination of autopsy tissues from children aged from 5 to 34 months. Hepatic lesions indicative of systemic infection were also found in four of the children. The viral etiology was confirmed in three cases by in-situ hybridization, electron-microscopy and immunofluorescence performed in paraffin-embedded tissues, and in one case by cell culture isolation of adenovirus type 2 from nasopharyngeal exudate. Routine testing by methods additional to conventional light microscopy would probably have revealed a larger number of adenovirus infections among the 1,103 autopsy records analyzed in this study.
