Abstract
Detection of rotavirus by polyacrylamide gel electrophoresis in combination with silver staining and by enzyme-linked immunosorbent assay showed 96.7% identical results in tests with 1,304 stool specimens from diarrheic patients. The polyacrylamide gel electrophoresis method can be modified to reduce cost and working time. Phenol extraction of stools, however, is essential in maintaining the sensitivity of the method.
