    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.

    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 erythema infectiosum. 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.

    The Receptor-Binding Domain in the VP1u Region of Parvovirus B19.
    Viruses 2016 Feb 24;8(3):61. Epub 2016 Feb 24.
    Department of Chemistry and Biochemistry, University of Bern, Bern 3012, Switzerland.
    Parvovirus B19 (B19V) is known as the human pathogen causing the mild childhood disease erythema infectiosum. B19V shows an extraordinary narrow tissue tropism for erythroid progenitor cells in the bone marrow, which is determined by a highly restricted uptake. We have previously shown that the specific internalization is mediated by the interaction of the viral protein 1 unique region (VP1u) with a yet unknown cellular receptor. Read More

    No evidence of persistent parvovirus B19 viremia among Iranian patients with HIV after a 1-year follow-up.
    Arch Virol 2016 May 10;161(5):1183-7. Epub 2016 Feb 10.
    Clinical Research Department, Pasteur Institute of Iran, No 69, Pasteur Ave., Tehran, 13164, Iran.
    Recent studies have demonstrated that, in common with other latent viruses, parvovirus B19 infection can be controlled by the host immune response but may persist in some places such as the bone marrow. Persistent B19 infection has been found in both immunocompetent and immunocompromised individuals, such as patients infected with human immunodeficiency virus (HIV). However, there is limited data regarding long-term B19 viremia in HIV patients. Read More

    Common Skin Rashes in Children.
    Am Fam Physician 2015 Aug;92(3):211-6
    University of Missouri-Columbia School of Medicine, Columbia, MO, USA.
    Because childhood rashes may be difficult to differentiate by appearance alone, it is important to consider the entire clinical presentation to help make the appropriate diagnosis. Considerations include the appearance and location of the rash; the clinical course; and associated symptoms, such as pruritus or fever. A fever is likely to occur with roseola, erythema infectiosum (fifth disease), and scarlet fever. Read More

    Predicting the characteristics of the aetiological agent for Kawasaki disease from other paediatric infectious diseases in Japan.
    Epidemiol Infect 2016 Feb 23;144(3):478-92. Epub 2015 Jul 23.
    Institute of Industrial Science,the University of Tokyo,Komaba,Meguro,Tokyo,Japan.
    Although Kawasaki disease (KD), which was first reported in the 1960s, is assumed to be infectious, its aetiological agent(s) remains unknown. We compared the geographical distribution of the force of infection and the super-annual periodicity of KD and seven other paediatric infectious diseases in Japan. The geographical distribution of the force of infection, which was estimated as the inverse of the mean patient age, was similar in KD and other paediatric viral infections. Read More

    Parvovirus B19 infection as a cause of acute myositis in an adult.
    Rev Bras Reumatol 2015 Mar-Apr;55(2):185-8. Epub 2014 Oct 5.
    Divisão de Hematologia, Departamento de Medicina Interna, Faculdade de Medicina, Universidade Bezmialem Vakif, Istambul, Turquia.
    Parvovirus B19 infection is often asymptomatic, but clinical expressions may include transient aplastic crisis, erythema infectiosum, non-immune hydrops fetalis, and chronic red cell aplasia. This virus has also been associated with rheumatoid arthritis and other autoimmune connective tissue diseases; however, we could not identify any acute adult myositis case developed after a Parvovirus B19 infection in the literature. For this reason, we would like to present a rare case of acute myositis developed after Parvovirus B19 infection. Read More
