Abstract:
A novel family of lymphotropic viruses, designated activating viruses or AV, have been discovered and isolated from primates, including humans (HAV) and marmosets (MAV). These viruses are infectious in primates and are associated with a wide variety of symptoms including anemia, chronic rhinitis, diarrhea, emaciation, enteritis, and neurologic abnormalities. Virus was isolated and purified from the blood of wasting marmosets and humans. These viruses have the following characteristics: (1) a double-stranded DNA genome; (2) an average diameter of 100 nm as determined by electron microscopy; (3) a spherical capsid with imperfect icosahedral symmetry; (4) a buoyant density of 1. 12-1. 20 as determined by sucrose gradient centrifugation; (5) major antigens of 32, 44, 48, 58. 8, and 106. 5 kDa as determined by Western blot analysis and silver staining of SDS-PAGE-resolved proteins obtained from MAV- or HAV-infected OMK cell lysates; (6) minor antigens of 26, 30. 5, 74.
