Human parvovirus B19 is a single-stranded DNA virus which preferentially targets the erythroblasts in the bone marrow. B19 infection commonly causes erythema infectiosum, arthralgia, fetal death, transient aplastic crisis in patients with shortened red cell survival, and persistent infection in people who are immunocompromised. Less common clinical manifestations include atypical skin rashes, n...

Plasma samples obtained at delivery from 885 pregnant Ghanaian women were tested for human parvovirus B19 DNA and B19-specific antibodies. Maternal-fetal transmission was evaluated by testing paired maternal plasma and umbilical cord blood samples, as well as newborn whole-blood samples when they were available. The B19 DNA seroprevalence rate in women was 1.8% (94% had genotype 3 strains), and...

Human parvovirus B19 infection was studied in 60 thalassemic patients in Thailand. Seroprevalence, persistence of parvovirus B19 and their genotypes were identified in blood samples. Prevalence of anti-parvovirus B19 IgG and DNA found in thalassemic patients were 38% and 13%, respectively. Anti-parvovirus B19 IgM could be detected in 4% of these positive anti-parvovirus B19 IgG patients. The se...

Human parvovirus B19 (B19) infects human erythroid cells expressing P antigen. However, some cell lines that were positive for P antigen failed to bind B19, whereas some cell lines had an ability to bind B19 despite undetectable expression of P antigen. We here demonstrate that B19 specifically binds with Ku80 autoantigen on the cell surface. Furthermore, transfection of HeLa cells with the gen...

OBJECTIVE To gain information concerning the association between parvovirus B19 infection and arthritis. METHODS Blood or synovial fluid, or both, from a total of 77 adult patients with various arthropathies (rheumatoid arthritis 13; mechanical arthropathies 11; crystal induced arthritis 13; idiopathic mono/oligoarthritis 25; suspicion of viral arthritis 15) were tested for the presence of th...

background and aims: human parvovirus b19, a member of the parvoviridae family, with single-stranded dna is a very minute non-enveloped virus. b 19 virus is mostly transmitted via the respiratory tract but some studies have been reported which b19 virus can be transmitted through blood and/or blood products. the aim of this study was to evaluate the prevalence of b19 among blood donors in tehra...

Parvovirus B19 infection leads to transient aplastic crises in individuals with chronic hemolytic anemias or immunodeficiency states. An additional unexplained sequela of B19 infection is thrombocytopenia. Because B19 is known to have a remarkable tropism for human erythropoietic elements, and is not known to replicate in nonerythroid cells, the etiology of this thrombocytopenia is uncertain. W...

BACKGROUND Pregnant women acutely infected with human parvovirus B19 (B19) may transmit the virus to the developing fetus. The mechanism whereby the virus interacts with the placenta is unknown. It is known that globoside receptor is required for successful infection of the target cells, which are the highly undifferentiated, actively dividing colony and burst-form units of the erythroid series...

An increased human parvovirus B19 infection rate has been observed in immunocompromised hosts. In this study, we sought to determine the prevalence of parvovirus B19 infection in adult cancer patients receiving multiple courses of systemic chemotherapy. From March 1999 through April 2000, 59 men and 68 women, with a median age of 49 (18 to 79) years, were enrolled in this study. They had receiv...
