14. Infecção latente pelo herpesvírus bovino tipo 1 em búfalos (Bubalus bubalis) no Rio Grande do Sul
RESUMO Apesar dos bovinos serem considerados os hospedeiros naturais do BoHV-1, estudos sorológicos têm sugerido que búfalos podem ser suscetíveis ao BoHV-1 e a outros alfa-herpesvírus geneticamente relacionados. O objetivo deste estudo foi detectar a presença de DNA viral de BoHV-1 em 202 amostras de gânglios trigêmeos de búfalos, pela técnica de

15. Human virome in nasopharynx and tracheal secretion samples
BACKGROUND In Brazil the implementation of the Sentinel Surveillance System of Influenza began in 2000. Central public health laboratories use reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for diagnosis of respiratory viruses, but this protocol identifies only specific targets, resulted in inconclusive diagnosis for many samples. T

16. Epidemiological survey of hepatitis C in a region considered to have high prevalence: the state of Minas Gerais, Brazil
Abstract INTRODUCTION: The prevalence of hepatitis C virus (HCV) infection is affected by demographic, virological, clinical, and lifestyle-related factors and varies in different regions in Brazil or worldwide. The present study aimed to clarify the epidemiological patterns of HCV infection in the interior region of Brazil. METHODS: This study was condu

18. Exploratory spatial analysis of HBV cases in Brazil between 2005 and 2017
RESUMO Objetivo: Analisar o padrão de distribuição espacial dos casos de hepatite causada pelo vírus B (HBV) e a mortalidade atribuída a esse agravo em todo o território nacional, nos anos de 2005, 2016 e 2017. Métodos : Trata-se de um estudo ecológico de análise espacial, utilizando dados do Sistema de Informação de Agravos de Notificação e d

19. Molecular Diagnostics of Dengue by Reverse Transcription-Loop Mediated Isothermal Amplification (RT-LAMP) in Disposable Polyester-Toner Microdevices
Dengue is one of the most prevalent infectious tropical diseases in the world, with high incidence in over 100 countries. Rapid and reliable diagnosis of dengue is of great importance for public health. To simplify molecular diagnostics, isothermal amplification techniques have recently emerged as an alternative to conventional methods of deoxyribonucleic ac

20. Clinical, laboratorial diagnosis and prophylaxis of measles in Brazil
RESUMO O sarampo é uma doença exantemática febril aguda de etiologia viral altamente contagiosa. É causa de morbidade e mortalidade de crianças em países em desenvolvimento, ao passo que se tornou mais rara em países desenvolvidos devido à vacinação. O diagnóstico diferencial deve ser realizado em relação a outras doenças da infância, como inf

21. Epidemiological profile of Zika, Dengue and Chikungunya virus infections identified by medical and molecular evaluations in Rondonia, Brazil
ABSTRACT Several arboviruses have emerged and/or re-emerged in North, Central and South-American countries. Viruses from some regions of Africa and Asia, such as the Zika and Chikungunya virus have been introduced in new continents causing major public health problems. The aim of this study was to investigate the presence of RNA from Zika, Dengue and Chikung

22. Viral etiology of acute respiratory infections in children in Southern Iran
Abstract INTRODUCTION: Prevalence of influenza A virus (Flu-A), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) was assessed in children with acute respiratory infections (ARIs). METHODS: Nasopharyngeal aspirates and throat swabs were subjected to real-time polymerase chain reaction (PCR) to detect RSV and Flu-A and to conventional PCR

23. Potencial do teste IGRA (Interferon Gama Release Assay) para o diagnóstico de tuberculose ocular. Revisão e análise comparativa com o teste tuberculínico cutâneo (PPD)
Resumo A detecção precisa da infecção latente por tuberculose está se tornando cada vez mais importante devido ao aumento do uso de medicamentos imunossupressores e da epidemia do vírus da imunodeficiência humana, o que aumentou o risco de reativação à tuberculose ativa (TB). O Teste IGRA QuantiFERON® TB Gold apresenta vantagens frente ao teste de

24. Analysis of tRNA halves (tsRNAs) in serum from cattle challenged with bovine viral diarrhea virus
Abstract Acute infections of bovine viral diarrhea virus (BVDV) lead to a range of clinical presentations. Laboratory tests for detection depend on collection of samples during a short viremia. Acutely infected animals remain largely undiagnosed. Transfer RNA halves (tsRNAs) are hypothesized to function like microRNAs to regulate gene expression during an im
