1. Molecular diversity of human parvovirus B19 during two outbreaks of erythema infectiosum in Brazil
Abstract This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996–2006, a period with two distinct outbreaks of B19V infection: 1999–2000 and 2004–2005. A total of 27 sera from patients with erythema infectiosum and f

2. Genotyping of human parvovirus B19 in clinical samples from Brazil and Paraguay using heteroduplex mobility assay, single-stranded conformation polymorphism and nucleotide sequencing
Heteroduplex mobility assay, single-stranded conformation polymorphism and nucleotide sequencing were utilised to genotype human parvovirus B19 samples from Brazil and Paraguay. Ninety-seven serum samples were collected from individuals presenting with abortion or erythema infectiosum, arthropathies, severe anaemia and transient aplastic crisis; two addition

3. Parvovirus B19 antibodies and correlates of infection in pregnant women attending an antenatal clinic in central Nigeria
Human parvovirus B19 infection is associated with spontaneous abortion, hydrops foetalis, intrauterine foetal death, erythema infectiosum (5th disease), aplastic crisis and acute symmetric polyarthropathy. However, data concerning Nigerian patients with B19 infection have not been published yet. The purpose of this study was to establish the prevalence of B1

4. FreqÃÃncia de sarampo, rubÃola, dengue e eritema infeccioso em casos suspeitos de sarampo e rubÃola no Estado de Pernambuco, no perÃodo de 2001 â 2004
O diagnÃstico das doenÃas exantemÃticas virais apresenta muitas falhas quando baseado apenas em critÃrios clÃnicos, principalmente nos paÃses onde os casos de sarampo e rubÃola sÃo raros. Estudos realizados em diversos paÃses apontam outras viroses determinantes de doenÃas exantemÃticas confundidas com sarampo e rubÃola. Para verificar a freqÃÃ

5. Anti-VP1 and anti-VP2 antibodies detected by immunofluorescence assays in patients with acute human parvovirus B19 infection
Acute human parvovirus B19 infection is followed by an antibody response to the structural proteins of the viral capsid (VP1 and VP2). We used 80 sera collected from 58 erythema infectiosum and 6 transient aplastic crisis patients to test IgM and IgG antibodies against these two proteins in an immunofluorescence assay (IFA) using Sf9 cells infected with reco

6. Two family members with a syndrome of headache and rash caused by human parvovirus B19
Human parvovirus B19 infection can cause erythema infectiosum (EI) and several other clinical presentations. Central nervous system (CNS) involvement is rare, and only a few reports of encephalitis and aseptic meningitis have been published. Here, we describe 2 cases of B19 infection in a family presenting different clinical features. A 30 year old female wi

7. Analysis of Nucleotide Sequences of Human Parvovirus B19 Genome Reveals Two Different Modes of Evolution, a Gradual Alteration and a Sudden Replacement: a Retrospective Study in Sapporo, Japan, from 1980 to 2008▿
There have been no long-term systematic analyses of the molecular epidemiology of human parvovirus B19 (B19V). We investigated the variations of nucleotide sequences of B19V strains collected in Sapporo, Japan, from 1980 to 2008. In that period, six outbreaks of erythema infectiosum occurred regularly at 5-year intervals. The B19V strains collected successiv

8. Evaluation of a synthetic-peptide enzyme-linked immunosorbent assay for immunoglobulin M to human parvovirus B19.
A synthetic peptide corresponding to a part of the virus protein 1-virus protein 2 overlapping region of human parvovirus B19 was used in an indirect enzyme-linked immunosorbent assay. Antibodies of the immunoglobulin (Ig) M class were measured in serum samples from patients with erythema infectiosum and controls. In comparison with an IgM assay using native

9. Prokaryotic expression of a VP1 polypeptide antigen for diagnosis by a human parvovirus B19 antibody enzyme immunoassay.
To produce parvovirus B19 antigen for diagnostic purposes, partially overlapping segments covering the genes encoding the viral structural proteins VP1 and VP2 were cloned into expression vectors. The constructs were induced in Escherichia coli, resulting in the expression of beta-galactosidase fusion proteins. In immunoblotting experiments with sera from pa

10. The VP1 Unique Region of Parvovirus B19 and Its Constituent Phospholipase A2-Like Activity
Parvovirus B19 is the causative agent of erythema infectiosum. In addition, parvovirus B19 infection may be associated with other disease manifestations, namely, thrombocytopenia or granulocytopenia, spontaneous abortion or hydrops fetalis in pregnant women, acute and chronic arthritis, and systemic lupus erythematosus. Based on sequence homology data, a pho

11. Simultaneous Detection of Measles Virus, Rubella Virus, and Parvovirus B19 by Using Multiplex PCR
We describe here a multiplex reverse transcription-PCR (RTMNPCR) assay designed to detect and differentiate measles virus, rubella virus, and parvovirus B19. Serial dilution experiments with vaccine strains that compared cell culture isolation of measles in B95 cells and rubella in RK13 cells showed sensitivity rates of 0.004 50% tissue culture infective dos

12. Human Parvovirus B19
Parvovirus B19 (B19) was discovered in 1974 and is the only member of the family Parvoviridae known to be pathogenic in humans. Despite the inability to propagate the virus in cell cultures, much has been learned about the pathophysiology of this virus, including the identification of the cellular receptor (P antigen), and the control of the virus by the imm
