Abstract
The virion RNAs of six independent isolates of Drosophila C virus (DCV) have been characterized by ribonuclease T1 oligonucleotide fingerprinting. All six isolates share common large oligonucleotides. Two of the isolates, from Vigier and Charolles, are closely related while a third French isolate from Gif is more distantly related. The other three isolates, two from Morocco (Taroudant and Ouarzazate) and one from the French Antilles were mixtures of more than one variant of DCV, but were clearly related to the three French isolates.
