Infection with parvovirus B19 causes several clinical syndromes (fifth disease, transient aplastic crisis, pure red cell aplasia, and hydrops fetalis) and may contribute to other illnesses. B19 has been linked to renal disease in three settings: As a cause of acute glomerulopathy and as a cause of anemia in ESRD and kidney transplantation. Case reports implicate parvovirus in the pathogenesis o...

BACKGROUND/AIM Human parvovirus B19 is a pathogen that affects different parts of the body. We planned this study because of the lack of data on B19 seroprevalence based on different body-system diseases. MATERIALS AND METHODS The prevalence of parvovirus B19 antibodies was investigated retrospectively in 1239 patients by review of medical records from 2009-2012, according to their diseases c...

The genome of the human parvovirus B19 contains a transcriptional promoter (BP06) at map position 6, upstream from the nonstructural protein genes. By cotransfecting HeLa cells with this promoter cloned before the chloramphenicol acetyltransferase (CAT) gene together with a plasmid containing almost the whole B19 genome, we showed that BP06 is transactivated by a B19 gene product. The transacti...

Objectives: Facilitate risk assessment of vital complications in fetuses of pregnancies affected by acute parvovirus B19 infection. Design: Study of the natural course of maternal parvovirus B19 infection in four cases, from early pregnancy on. Setting: University medical center in the Netherlands. Population: Pregnant mothers attending obstetric services. Methods: Serial measurements of the ma...

INTRODUCTION Human parvovirus B19 is found worldwide. It causes various infections, including fifth disease (erythema infectiosum) in small children, acute arthropathy in adults, transient aplastic crisis and chronic anemia in immunocompromised patients and even fetal infection, which may result in intrauterine fetal death or fetal hydrops. Many of these manifestations of B19 infection are caus...

Parvovirus B19 is a common human pathogen maintained by horizontal transmission between acutely infected individuals. However, B19 virus can also be detected in tissues throughout the life of the host, although little is understood about the nature of such persistence. In the current study, we created large VP1/2 sequence data sets of plasma- and tissue (autopsy)-derived variants of B19 virus w...

To understand the evolutionary dynamics of human parvovirus B19, we analyzed VP1 and VP2 gene sequences of B19 sampled from Belém (Amazon), the city of São Paulo, Brazil and globally. Our analysis revealed a strikingly different pattern of evolutionary change for those viral lineages introduced into Belém, which exhibited a higher rate of nonsynonymous substitutions compared to those viruses sa...

The target cell specificity of the B19 parvovirus infection was examined by isolating highly enriched hematopoietic progenitor and stem cells from normal human bone marrow. The efficiency of the B19 parvovirus replication in enriched erythroid progenitor cells was approximately 100-fold greater than that in unseparated bone marrow cells. The more-primitive progenitor cells identical to or close...

For the production of dengue-vaccine candidates, empty capsids, or virus-like particles (VLPs), of parvovirus B19 that carry dengue 2-specific epitopes were employed as antigen carriers. Two epitopes (comprising amino acids 352-368 and 386-397) of domain BIII of the envelope glycoprotein were chosen to produce recombinant B19 VLPs for immunization of BALB/c mice. Serum samples from immunized mi...

Human parvovirus (HPV) B19 induced aplastic crisis in a family leading to the diagnosis of hereditary spherocytosis (HS) is a very rare condition being barely reported in the literature. We herein report a 4-year-old girl, her brother, and their mother who all presented with progressive pallor and jaundice after a febrile illness. The HPV B19 was diagnosed using polymerase chain reaction (PCR) ...
