13. Bovine alphaherpesvirus 1 and 5 in semen from bulls presenting genital lesions under field conditions in Brazil
RESUMO Os alfa-herpesvírus bovinos 1 e 5 (BoHV-1/5) são importantes patógenos de doença respiratória, reprodutiva e neurológica em bovinos. O objetivo deste estudo foi investigar a frequência de detecção de anticorpos neutralizantes contra BoHV-1/5 em amostra de soro e detectar DNA viral em sêmen de touros do rebanho bovino localizado nas fazendas

14. Could human coronavirus OC43 have co-evolved with early humans?
Abstract This paper reports on an investigation of the role of codon usage evolution on the suggested bovine-to-human spillover of Bovine coronavirus (BCoV), an enteric/respiratory virus of cattle, resulting in the emergence of the exclusively respiratory Human coronavirus OC43 (HCoV-OC43). Analyses based on full genomes of BCoV and HCoV-OC43 and on both hum

15. Evolution of equine influenza viruses (H3N8) during a Brazilian outbreak, 2015
Abstract Equine influenza is one of the major respiratory infectious diseases in horses. An equine influenza virus outbreak was identified in vaccinated and unvaccinated horses in a veterinary school hospital in São Paulo, SP, Brazil, in September 2015. The twelve equine influenza viruses isolated belonged to Florida Clade 1. The hemagglutinin and neuramini

16. Human metapneumovirus in Southern Brazil
Abstract INTRODUCTION Infections caused by respiratory viruses are important problems worldwide, especially in children. Human metapneumovirus (hMPV) is a respiratory pathogen and causes severe infections with nonspecific symptoms. This study reports the hMPV occurrence and dissemination in southern Brazil and compares the frequency of occurrence of this v

17. In silico analysis of amino acid variation in human respiratory syncytial virus: insights into immunodiagnostics
BACKGROUND The highly contagious nature of human respiratory syncytial virus (HRSV) and the gravity of its infection in newborns and vulnerable adults pose a serious public health problem. Thus, a rapid and sensitive diagnostic test for viral detection that can be implemented upon the first appearance of symptoms is needed. The genetic variation of the vir

19. Molecular epidemiology of influenza A(H1N1)PDM09 hemagglutinin gene circulating in São Paulo State , Brazil: 2016 anticipated influenza season
ABSTRACT Compared to previous years, seasonal influenza activity commenced early in São Paulo State, Brazil, Southern hemisphere during the 2016 year. In order to investigate the genetic pattern of influenza A(H1N1)pdm09 in the State of Sao Paulo a total of 479 respiratory samples, collected in January by Sentinel Surveillance Units, were screened by real-t

20. Detection of respiratory viruses in shelter dogs maintained under varying environmental conditions
Abstract Three dog shelters in Rio Grande do Sul were investigated for associations between the occurrence of respiratory viruses and shelter environmental conditions. Nasal secretions randomly collected during the cold season were tested via PCR, and this data collection was followed by nucleotide sequencing of the amplicons. In shelter #1 (poor sanitary an

22. Patterns of influenza B circulation in Brazil and its relevance to seasonal vaccine composition
Abstract Data on the burden of disease and circulation patterns of influenza B lineages for Brazil are limited. This review aims to describe the pattern of influenza B occurrence in Brazil to have a better understanding of its epidemiology and its relevance when considering seasonal influenza vaccine composition. A review of the data including analysis of in

23. Viral aetiology of common colds of outpatient children at primary care level and the use of antibiotics
Although antibiotics are ineffective against viral respiratory infections, studies have shown high rates of prescriptions worldwide. We conducted a study in Brazil to determine the viral aetiologies of common colds in children and to describe the use of antibiotics for these patients. Children up to 12 years with common colds were enrolled from March 2008-Fe
