The recently described monomer covalently closed linear replicative form DNA (Mccl RF DNA) of Aleutian disease parvovirus (ADV) is an infectious intermediate of the viral DNA replication cycle. Transfection of highly purified Mccl RF DNA into susceptible feline kidney cells (CCC clone 81 cells) resulted in viral DNA replication, expression of viral proteins and synthesis of infectious progeny virus. Mccl RF DNAs generated under permissive (32 degrees C) or non-permissive (37 degrees C) conditions were shown to be biologically indistinguishable. The accumulation of the Mccl RF DNA form at the non-permissive temperature in vitro strongly resembles that in bone marrow cells of naturally infected mink and may reflect one mechanism contributing to virus persistence of ADV in vivo.

UI	MeSH Term	Description	Entries
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D000454	Aleutian Mink Disease Virus	A species of PARVOVIRUS that causes a disease in mink, mainly those homozygous for the recessive Aleutian gene which determines a desirable coat color.	Aleutian Disease Virus,Aleutian Mink Disease Parvovirus
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014162	Transfection	The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES.	Transfections
D014779	Virus Replication	The process of intracellular viral multiplication, consisting of the synthesis of PROTEINS; NUCLEIC ACIDS; and sometimes LIPIDS, and their assembly into a new infectious particle.
