Confocal microscopy allowed us to localize viral nonstructural (NS) and
capsid (VP) proteins and DNA simultaneously in cells permissively infected
with Aleutian mink disease parvovirus (ADV). Early after infection, NS
proteins colocalized with viral DNA to form intranuclear inclusions,
whereas VP proteins formed hollow intranuclear shells around the
inclusions. Later, nuclei had irregular outlines and were virtually free of
ADV products. In these cells, inclusions of viral DNA with or without
associated NS protein were embedded in cytoplasmic VP protein. These
findings implied that ADV replication within an infected cell is regulated
spatially as well as temporally.
