Replication of bovine parvovirus
Bovine parvovirus (BPV) is a small icosahedral virus containing single stranded DNA and belongs to the group of nondefective parvoviruses. Research on this virus group has revealed that viral replication occurs in cycling cells only, and evidence exists that the required factor provided by cycling …

Molecular Mechanism of Parvovirus Infection
… cytopathic effects induced during infections of parvovirus B19 (B19V) and minute virus of canines (MVC); 2) identifying the role of EpoR signaling in supporting B19V replication in erythroid of progenitor cells. To the first part, we take advantage of a recently developed in vitro permissive B19V …

Infectivity and Epidemiological Studies on Bovine Parvovirus
Bovine parvoviruses (BPV) are widespread in the cattle population and associated with disease of the reproductive and possibly with the respiratory tract. The virus has been recovered from cattle with clinical signs of respiratory disease. Four established cell lines (bovine turbinates (BT), Madin …

Isolation and characterization of bovine parvovirus DNA
The best characterized of the autonomous parvoviruses are those of rodent origin. The purpose of this study was to examine the physicochemical characteristics of the genome of an autonomous parvovirus of non-rodent origin, bovine parvovirus (BPV). BPV was isolated from infected cells by …

Analysis of factors that affect parvovirus expression
… the promoter located at map unit 4 of the bovine parvovirus (BPV) genome were determined. The autonomous parvoviruses, of which BPV is a member, contain two transcriptional units with promoters active in temporal order during infection. BPV proteins also appear in the same temporal order; the …

Molecular Study of the B19 (Human) Pathogenic Parvovirus
<p>The B19 (human) parvovirus is a small single stranded DNA virus of 5.4 kilobases. B19 is specific for erythroid progenitor cells and has been propagated in vitro only with human erythroid bone marrow. Replication of viral DNA and the viral protein products of B19 appear similar to those of other …

Electron microscopy of bovine Parvovirus DNA replication intermediates
… DNA species have been isolated from autonomous parvovirus-infected cells that could·not be demonstrated in mock-infected cells. The DNA species were termed replicative forms and intermediates. The purpose of this study was to isolate and characterize the replicative forms from bovine parvovirus …

Cellular factors and viral elements for parvovirus replication
Autonomous parvoviruses, such as bovine parvovirus (BPV), need a factor present at the S-phase of the cell cycle for a productive infection, while dependent parvoviruses, the adenoassociated viruses (AAVs), require a helper virus to complete an infectious cycle. However, AAV can replicate …

Bovine parvovirus and bovine enterovirus in mixed infections
… with 2mM hydroxyurea were infected with bovine parvovirus and bovine enterovirus in order to study the events occurring when DNA and RNA viruses mixedly infect single cells. The objectives of this research were threefold. First, to determine the effects of single infection of synchronized bovine …

Untersuchungen der genetischen Varianz aktueller Isolate des porzinen Parvovirus
… variability of recent isolates of porcine parvovirus The aim of this study was to review the antigenetic variability of porcine parvovirus and to examine the role of porcine parvovirus in reproductive failure. Organ specimens of 500 fetuses and stillborn piglets from a total of 172 farms …

Phospholipase A 2 in der Parvovirus MVMp induzierten Zelllyse
Das autonome Parvovirus Minute Virus of Mice MVMp ist ein onkolytisches Virus, da es selektiv neoplastisch transformierte Zellen infiziert und tötet. Während viele zytotoxische Effekte, die eine MVMp Infektion hervorruft, auf Aktivitäten des viralen NS1 Proteins zurückgeführt wurden, sind die …

Transcription and encapsidation in parvoviruses LuIII and bovine parvovirus
The termini of the autonomous parvovirus LuIII, which encapsulates plus and minus DNA strands equally, were cloned and sequenced. The left and right termini of LuIII differ in nucleotide sequence and these termini can assume T- and U-shaped intra-strand base-paired structures, respectively. The …

Die Serumprävalenz von Parvovirus B19 bei rheumatischen Erkrankungen im Kindesalter
… es, einen möglichen Zusammenhang zwischen einer Parvovirus B19-Infektion und der Ätiologie und Pathogenese der Juvenilen idiopathischen Arthritis (JIA) zu untersuchen. Hierzu wurden von insgesamt 382 Patienten der Rheumasprechstunde der Kinderpoliklinik der Universität Würzburg Serumproben auf …

Molecular cloning and analysis of the genome of bovine parvovirus
The genome of bovine parvovirus (BPV) has been cloned by blunt end ligation of double-stranded virion DNA into the plasmid pUC8. The resulting genomic clones were infectious after transfection into bovine fetal lung (BFL) cells. Sequencing of the plasmids demonstrated that deletions were common at …

Cis and trans signals for the replication of bovine parvovirus
… for the S-phase factor required for autonomous parvovirus replication. The BPV ori thus appears to function by binding both cellular and viral proteins for the initiation of DNA synthesis from the hairpinned termini. The comparison of the BPV and LPV genome sequence suggest that the genomic …

Assessment of Cell Death Parameters in Bovine Parvovirus-Infected EBTr Cells
Bovine parvovirus (BPV) is a helper-independent parvovirus. It has a small icosahedral capsid with a single stranded DNA genome. It is a highly stable virus with a narrow host range. It causes acute gastroenteritis in calves. It is considered to be a cytolytic virus because it kills the host cells. …
