In the present study, we sequenced and analysed the complete genomes of a novel duck parvovirus (NM100) isolates derived from Muscovy ducks in Fujian, Southeast China. According to the phylogenetic analysis, based on the complete genome and VP1 gene showed that novel duck parvovirus strain NM100 belong to the MDPV clusters, whereas the VP3 gene showed that strain NM100 belong to the GPV cluster...
Serological, sequence, and in vitro host range analyses of feline parvovirus (FPV) isolates in Vietnam and Taiwan revealed that more than 80% of the isolates were of the canine parvovirus (CPV) type, rather than feline panleukopenia virus (FPLV). Although parvovirus isolates from three Vietnamese leopard cats were genetically related to CPV type 2a or 2b, they had a natural mutation of VP2 resi...
Waterfowl parvoviruses are classified into goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV) according to their antigenic features and host preferences. A novel duck parvovirus (NDPV), identified as a new variant of GPV, is currently infecting ducks, thus causing considerable economic loss. This study analyzed the molecular evolution and population dynamics of the emerging parvovirus ca...
Parvovirus B19 is a widespread infection that may affects 1-5% of pregnant women, mainly with normal pregnancy outcome. The prevalence of infection is higher during epidemics - between 3 and 20% with sero-conversion rate of 3-34%. Infection during pregnancy can cause a variety of other signs of fetal damage. The risk of adverse fetal outcome is increased if maternal infection occurs during the ...
Parvovirus B19 is a small non-enveloped single-stranded DNA virus of the family Parvoviridae and genus Erythrovirus. B19 virus is most known for causing erythema infectiosum (fifth disease) in children as well as numerous other diseases such as arthropathy in adults, Transient aplastic crisis in patients with increased erythropoiesis and persistent anemiain in immunocompromised patients. Parvov...
A 2 year old boy developed acute cerebellar ataxia in association with erythema infectiosum. During the disease, genomic DNA and antibodies against human parvovirus B19 were detected in serum but not in cerebrospinal fluid. Parvovirus B19 associated acute cerebellar ataxia might occur due to transient vascular reaction in the cerebellum during infection.
Parvovirus B19 is recognized as a rare cause of pure red cell aplasia (PRCA) in allogeneic stem cell (SCT) and solid organ transplant patients. We report a patient with Hodgkin's disease who developed PRCA due to parvovirus B19 after autologous SCT and who had an excellent response after treatment with gamma-globulin.
Human parvovirus 4 infections are primarily associated with parenteral exposure in western countries. By ELISA, we demonstrate frequent seropositivity for antibody to parvovirus 4 viral protein 2 among adult populations throughout sub-Saharan Africa (Burkina Faso, 37%; Cameroon, 25%; Democratic Republic of the Congo, 35%; South Africa, 20%), which implies existence of alternative transmission r...
An aplastic crisis associated with parvovirus infection occurred in a patient suffering from hereditary erythrocytic multinuclearity associated with a positive acidified (Hams) test (HEMPAS). This case emphasises that any patient who has a shortened red cell survival is susceptible to an aplastic crisis induced by parvovirus.
