[Biochemical study of rotavirus strains isolated in New Caledonia between 1980 and 1983. Electrophoretypes]

Between 1980 and 1983, 150 Rotavirus strains have been identified by ELISA test. RNA was extracted from 90 strains. We used a very simple and rapid extraction technique. Polyacrylamide gel electrophoresis permits the separation of double stranded RNA segments. The system of classification we retained, allows to recognize 8 classes of electrophoretypes. This study confirms the great variability of human rotaviruses.
