title: Cytomegalovirus strain differentiation by DNA restriction analysis.
abstract: The heterogeneity of CMV DNA obtained from standard strains and new isolates, including a vaccination strain (Towne 125), was investigated. The cleavage patterns produced by the restriction endonucleases Eco RI and Bam 1 revealed stable strain specificities of CMV. On the other hand, a remarkable homology of sequence-specific CMV DNA fragmentation was demonstrated. A CMV subtyping relevant to clinical questions seems to be improbable.
