Afr Health Sci 2018 Sep;18(3):496-502

University of Zambia, School of Medicine, Department of Pathology and Microbiology.

Background: Human Parvovirus (B19V) is a small, single-stranded, non-enveloped DNA virus which is pathogenic to humans causing a wide array of clinical complications which include erythema infectiosum, aplastic crisis and hydrops foetalis. It is generally harmless in healthy individuals but may be life threatening in immunocompromised individuals such as patients with sickle cell disease, cancer, HIV and pregnant women. It has been shown to be transmissible by blood transfusion but donor screening for the virus is not yet mandatory in most sub-Saharan African countries including Zambia. Read More

Ancient human parvovirus B19 in Eurasia reveals its long-term association with humans.

Proc Natl Acad Sci U S A 2018 07 2;115(29):7557-7562. Epub 2018 Jul 2.

Center for Pathogen Evolution, Department of Zoology, University of Cambridge, CB2 3EJ Cambridge, United Kingdom;

Human parvovirus B19 (B19V) is a ubiquitous human pathogen associated with a number of conditions, such as fifth disease in children and arthritis and arthralgias in adults. B19V is thought to evolve exceptionally rapidly among DNA viruses, with substitution rates previously estimated to be closer to those typical of RNA viruses. On the basis of genetic sequences up to ∼70 years of age, the most recent common ancestor of all B19V has been dated to the early 1800s, and it has been suggested that genotype 1, the most common B19V genotype, only started circulating in the 1960s.

Parvovirus B19: A Cause of Sepsislike Syndrome in an Infant.

Pediatrics 2018 Jun;141(6)

Department of Pediatrics, Graduate School of Medical and Dental Sciences, Niigata University, Niigata, Japan.

Parvovirus B19 (PB19) is an important human pathogen that results in a wide spectrum of clinical outcomes, from mild, self-limiting erythema infectiosum in immunocompetent children and arthralgia in adults to lethal cytopenia in immunocompromised patients and intrauterine fetal death. However, there have been few reports of PB19 infection in neonates or young infants (aged 28-90 days), and no previous reports contained descriptions of PB19 infection as a cause of sepsislike syndrome in this age group. We report a case of sepsislike syndrome caused by PB19 infection in a 56-day-old infant whose mother had polyarthralgia at the time of his admission. Read More

J Virol 2018 04 28;92(8). Epub 2018 Mar 28.

Department of Microbiology, Molecular Genetics and Immunology, University of Kansas Medical Center, Kansas City, Kansas, USA

Human parvovirus B19 (B19V) expresses a single precursor mRNA (pre-mRNA), which undergoes alternative splicing and alternative polyadenylation to generate 12 viral mRNA transcripts that encode two structural proteins (VP1 and VP2) and three nonstructural proteins (NS1, 7.5-kDa protein, and 11-kDa protein). Splicing at the second 5' donor site (D2 site) of the B19V pre-mRNA is essential for the expression of VP2 and the 11-kDa protein. Read More

Am J Dermatopathol 2018 Feb;40(2):e19-e24

Dermatology, and.

Human parvovirus B19 (B19V) causes a number of skin exanthemas and has been related to both cutaneous and systemic diseases. Tropism of the virus for the rapidly proliferating erythroid progenitor cells in the bone marrow and fetal liver explains the pathogenesis of anemia and fetal hydrops. The cutaneous lesions of erythema infectiosum and other B19V-related exanthemas have been attributed to the deposition of immune complexes in the skin. Read More

Molecular diversity of human parvovirus B19 during two outbreaks of erythema infectiosum in Brazil.

Braz J Infect Dis 2017 Jan - Feb;21(1):102-106. Epub 2016 Nov 30.

Universidade Federal Fluminense, Faculdade de Medicina, Programa de Pós Graduação em Ciências Médicas, Niterói, RJ, Brazil; Universidade Federal Fluminense, Faculdade de Medicina, Disciplina de Doenças Infecciosas e Parasitárias, Niterói, RJ, Brazil.

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 five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b).

Parvovirus B19 infection presenting concurrently as papular-purpuric gloves-and-socks syndrome and bathing-trunk eruption.

Clin Exp Dermatol 2017 Jan 30;42(1):58-60. Epub 2016 Nov 30.

Dermatology Service, Fundación Jiménez Díaz, Madrid, Spain.

Parvovirus B19 infection can cause a wide range of cutaneous manifestations, including papular-purpuric gloves-and-socks syndrome (PPGSS) and petechial bathing trunk eruption. We report a case of an immunocompetent woman with a primary parvovirus B19 infection presenting as concurrent PPGSS and petechial bathing trunk eruption. Parvovirus B19 seroconversion was confirmed several days after the onset of the clinical manifestations. Read More

Office of the Dean, James H. Quillen College of Medicine, East Tennessee State University, Johnson City, TN.

Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent. Read More

DNA Binding and Cleavage by the Human Parvovirus B19 NS1 Nuclease Domain.

Biochemistry 2016 Nov 17;55(47):6577-6593. Epub 2016 Nov 17.

Department of Chemistry and Biochemistry, University of Arizona , Tucson, Arizona 85721, United States.

Infection with human parvovirus B19 (B19V) has been associated with a myriad of illnesses, including erythema infectiosum (Fifth disease), hydrops fetalis, arthropathy, hepatitis, and cardiomyopathy, and also possibly the triggering of any number of different autoimmune diseases. B19V NS1 is a multidomain protein that plays a critical role in viral replication, with predicted nuclease, helicase, and gene transactivation activities. Herein, we investigate the biochemical activities of the nuclease domain (residues 2-176) of B19V NS1 (NS1-nuc) in sequence-specific DNA binding of the viral origin of replication sequences, as well as those of promoter sequences, including the viral p6 and the human p21, TNFα, and IL-6 promoters previously identified in NS1-dependent transcriptional transactivation.

Not the Usual Viral Suspects: Parvovirus B19, West Nile Virus, and Human T-Cell Lymphotrophic Virus Infections After Kidney Transplantation.

Semin Nephrol 2016 09;36(5):428-434

Division of Infectious Diseases and the William J von Liebig Center for Transplantation and Clinical Regeneration, Mayo Clinic, Rochester, MN. Electronic address:

Kidney transplant recipients are at increased risk of developing clinical disease due to uncommon opportunistic viral pathogens. Refractory anemia is classically associated with parvovirus B19 infection. West Nile virus has the propensity to cause fever and neurologic symptoms, while spastic paresis and lymphoma can be triggered by human T cell lymphotrophic virus. Read More

The VP1u Receptor Restricts Parvovirus B19 Uptake to Permissive Erythroid Cells.

Viruses 2016 Sep 28;8(10). Epub 2016 Sep 28.

Department of Chemistry and Biochemistry, University of Bern, Bern 3012, Switzerland.

Parvovirus B19 (B19V) is a small non-enveloped virus and known as the causative agent for the mild childhood disease . B19V has an extraordinary narrow tissue tropism, showing only productive infection in erythroid precursor cells in the bone marrow. We recently found that the viral protein 1 unique region (VP1u) contains an N-terminal receptor-binding domain (RBD), which mediates the uptake of the virus into cells of the erythroid lineage.

Virome characterisation from Guthrie cards in children who later developed acute lymphoblastic leukaemia.

Br J Cancer 2016 10 23;115(8):1008-1014. Epub 2016 Aug 23.

Department of Clinical Science, Intervention and Technology, CLINTEC, Karolinska Institutet, S-141 86 Stockholm, Sweden.

Background: Some childhood acute lymphoblastic leukaemias (ALL) can be traced back to a prenatal origin, where a virus infection could be involved in the first pre-leukaemic clone development. The DNA virome of 95 children who later developed ALL was characterised from neonatal blood spots (NBS) using unbiased next-generation sequencing (NGS) and compared with the virome of 95 non-ALL controls.

Methods: DNA was individually extracted from the ALL-patients and controls, pooled, randomly amplified and sequenced using the Illumina MiSeq Sequencing System. Read More
