1. Seroprevalence of arenavirus and hantavirus in indigenous populations from the Caribbean, Colombia
Abstract INTRODUCTION: In Colombia, there is insufficient epidemiological surveillance of zoonotic hemorrhagic viruses. METHODS: We performed a sero-epidemiological study in indigenous populations of Wayuü, Kankuamos, and Tuchin communities using Maciel hantavirus and Junin arenavirus antigens for IgG detection by ELISA. RESULTS IgG antibodies to hanta

2. Doença do corpúsculo de inclusão e espondilite por Salmonella sp. em uma Boa constrictor constrictor
RESUMO: Doença do corpúsculo de inclusão (IBD) é uma enfermidade caracterizada por corpúsculos intracitoplasmáticos em diversos tecidos, principalmente no sistema nervoso central, responsável pelos principais sinais clínicos atribuídos à doença que acomete Boas e Phytons de cativeiro; essa enfermidade tem sido uma preocupação mundial devido à a

3. Padronização de um teste de ELISA utilizando a nucleoproteína recombinante de vírus Junin como antígeno e triagem sorológica para Arenavírus na população de Nova Xavantina, Estado do Mato Grosso
INTRODUÇÃO: A febre hemorrágica por Arenavirus é uma severa doença emergente. MÉTODOS: Considerando que os níveis de anticorpos contra Arenavirus na população brasileira é totalmente desconhecido, nos padronizamos um teste de ELISA para detecção de anticorpos IgG usando uma nucleoproteína recombinante do vírus Junin como antígeno. Esta proteí

4. Circulating natural killer and γδ T cells decrease soon after infection of rhesus macaques with lymphocytic choriomeningitis virus
Rhesus macaques infected with the WE strain of lymphocytic choriomeningitis virus (LCMV-WE) serve as a model for human infection with Lassa fever virus. To identify the earliest events of acute infection, rhesus macaques were monitored immediately after lethal infection for changes in peripheral blood mononuclear cells (PBMCs). Changes in CD3, CD4, CD8 and C

5. Febres hemorrágicas por vírus no Brasil
Chamando a atenção para as febres hemorrágicas por vírus, que em sua maioria tem escassa informação divulgada e provavelmente são subnotificadas, mostra-se neste artigo casos clínicos das 4 doenças deste tipo que ocorrem no Brasil: febre amarela, dengue hemorrágico/síndrome de choque do dengue, febre hemorrágica por arenavírus e síndrome pulmon

6. Myristoylation of the RING Finger Z Protein Is Essential for Arenavirus Budding
The arenavirus small RING finger Z protein is the main driving force of arenavirus budding. The primary structure of Z is devoid of hydrophobic transmembrane domains, but both lymphocytic choriomeningitis virus (LCMV) and Lassa fever virus Z proteins accumulate near the inner surface of the plasma membrane and are strongly membrane associated. All known aren

7. Recombination Between Temperature-Sensitive Mutants of the Arenavirus Pichinde
High-frequency recombination was obtained with temperature-sensitive, conditionally lethal mutants of the arenavirus Pichinde.

8. Arenavirus Concentration by Molecular Filtration
Liter volumes of a human arenavirus pathogen (Machupo) and a nonpathogen (Tacaribe) were concentrated 30 to 100 times in less than 90 min without significant loss of particle infectivity.

9. The small RING finger protein Z drives arenavirus budding: Implications for antiviral strategies
By using a reverse genetics system that is based on the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV), we have identified the arenavirus small RING finger Z protein as the main driving force of virus budding. Both LCMV and Lassa fever virus (LFV) Z proteins exhibited self-budding activity, and both substituted efficiently for the late domai

10. An Arenavirus RING (Zinc-Binding) Protein Binds the Oncoprotein Promyelocyte Leukemia Protein (PML) and Relocates PML Nuclear Bodies to the Cytoplasm
The promyelocytic leukemia protein (PML) forms nuclear bodies which are altered in some disease conditions. We report that the cytoplasmic RNA virus lymphocytic choriomeningitis virus (LCMV) influences the distribution of PML bodies. In cells infected with LCMV, the Z protein and PML form large bodies primarily in the cytoplasm. Transient transfection studie

11. Characterization of the Genomic Promoter of the Prototypic Arenavirus Lymphocytic Choriomeningitis Virus†
The genome of the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) consists of two negative-sense, single-strand RNA segments designated L and S. Arenavirus genomes exhibit high sequence conservation at their 3′ ends. All arenavirus genomes examined to date have a conserved terminal sequence element (3′-terminal 20 nucleotides [nt]) though
