Abstract

Aleutian disease virus (ADV) was extracted and purified from infected mink. Nucleic acid extracted from the virus was examined in an electron microscope. Three different sizes of molecule, with approximate lengths of 1.2, 0.55, and 0.25 micron, were observed. The ratios of the large molecules to the small molecules were similar in all the particles prepared under different conditions. Equilibrium CsCl density gradient centrifugation showed that ADV nucleic acid had a buoyant density of 1.733 g/cm3. In Cs2SO4, ADV had a lower buoyant density than that of double-stranded RNA. These properties and its sensitivity to DNase suggested that ADV contains DNA. Thermal denaturation curves revealed that the DNA of ADV had a single-stranded configuration. Polypeptide analysis of ADV by polyacrylamide gel electrophoresis revealed the presence of four polypepties, with molecular weights of 30,000, 27,000, 20,500, and 14,000. These polypeptides were present in a ratio of 10:3:10:1, respectively. The data suggested that ADV is closely related to the members of the parvovirus groups.
