BACKGROUND Erythema infectiosum is the most common clinical manifestation of Parvovirus B19 infection although it has also been associated with rheumatologic diseases and various types of systemic vasculitides. Acute hepatitis and benign myositis however are rarely reported in association with Parvovirus B19 infection. CASE PRESENTATION Here we report a 14-year old male, who developed acute h...

In order to investigate the pathogenic mechanisms of parvovirus B19 in human colorectal cancer, plasmids containing the VP1 or VP2 viral capsid proteins or the NS1 non-structural proteins of parvovirus B19 were constructed and transfected into primary human colorectal epithelial cells and LoVo cells. Differential gene expression was detected using a human genome expression array. Functional gen...

BACKGROUND Human parvovirus B19 has been implicated as a primary etiologic agent of erythema infectiosum (fifth disease) and aplastic crisis in patients with chronic haemolytic anemias. Human parvovirus B19 is known to be associated with adverse effects on fetuses such as hydrops fetalis, intrauterine fetal death, and chronic anaemia in immunocompromized individuals. The objective of this study...

The blood group P antigen, known to be abundantly expressed on erythroid cells, has been reported to be the cellular receptor for parvovirus B19. We have described the development of recombinant parvovirus B19 vectors with which high-efficiency, erythroid lineage-restricted transduction can be achieved (S. Ponnazhagan, K. A. Weigel, S. P. Raikwar, P. Mukherjee, M. C. Yoder, and A. Srivastava, J...

Parvovirus B19 has a marked tropism for erythroid progenitor cells. This may lead to chronic anemia in predisposed individuals. The purpose of the study was to investigate the frequency of parvovirus B19 infections in patients with diagnosis of haematological disorders. In order to determine the diagnostic use of different markers of parvovirus B19 infection, serum specimens obtained from 79 pa...

Parvovirus B19 has been proposed as the etiological agent of fulminant hepatitis (FH) or hepatitis-associated aplastic anemia (HAA). We studied the prevalence of parvovirus B19 in liver-tissue samples from patients with FH and HAA and from control subjects. In the first study, parvovirus B19 DNA was detected by nested polymerase chain reaction (PCR) in 4 of 15 livers from patients with FH and i...

  Background and Objectives: Infection with parvovirus may induce spontaneous abortion, non-immune hydrops fetalis, and intrauterine death in full term infants. The aim of this study was to determine the frequency of parvovirus B19 in paraffin-embedded formalin fixed placental tissues in lost fetuses by PCR method and comparison with its frequency in healthy full term neonates as controls. Ma...

Parvovirus B19 has an extreme tropism for human erythroid progenitors. Here we propose the hypothesis explaining the tropism of human parvovirus B19. Our speculations are based on experimental results related to the capsid proteins VP1 and VP2. These proteins were not detectable in nonpermissive cells in course of these experiments, although the corresponding mRNAs were synthesized. Our interpr...

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) ...
