Bovine respiratory syncytial virus (BRSV) belongs to the pneumovirus genus within the family Paramyxoviridae and is a major cause of respiratory disease in young calves. BRSV is enveloped and contains a negative sense, single-stranded RNA genome encoding 11 proteins. The virus replicates predominantly in ciliated respiratory epithelial cells but also in type II pneumocytes. It appears to cause ...
The bovine respiratory syncytial virus (BRSV) is an enveloped, negative sense, single-stranded RNA virus belonging to the pneumovirus genus within the family Paramyxoviridae. BRSV has been recognized as a major cause of respiratory disease in young calves since the early 1970s. The analysis of BRSV infection was originally hampered by its characteristic lability and poor growth in vitro. Howeve...
Respiratory syncytial virus (RSV), a prominent cause of airway morbidity in children, maintains an excessive hospitalization rate despite decades of research. Host factors are assumed to influence the disease severity. As a first step toward identifying the underlying resistance mechanisms, we recently showed that inbred mouse strains differ dramatically as regards their susceptibility to pneum...
Respiratory syncytial virus-bronchiolitis is a major independent risk factor for subsequent asthma, but the causal mechanisms remain obscure. We identified that transient plasmacytoid dendritic cell (pDC) depletion during primary Pneumovirus infection alone predisposed to severe bronchiolitis in early life and subsequent asthma in later life after reinfection. pDC depletion ablated interferon p...
Respiratorni sincicijalni virus (RSV), RNA virus grupe Pneumovirus genus, familije Paramyxoviridae, uzrokuje bolesti respiratornog trakta kod dece i odraslih . Do navršene prve godine života 50% dece je inficirano RSV virusom i 20-40% te odojčadi razvije infekciju donjih respiratornih puteva ispoljenu kao bronhiolitis ili pneumonija. Inače, poseban rizik od komplikacija i smrtnog ishoda usled R...
Respiratory virus infections are often pathogenic, driving severe inflammatory responses. Most research has focused on localized effects of virus infection and inflammation. However, infection can induce broad-reaching, systemic changes that are only beginning to be characterized. In this study, we assessed the impact of acute pneumovirus infection in C57BL/6 mice on bone marrow hematopoiesis. ...
The first cases of infection caused by avian metapneumoviruses (aMPVs) were described in turkeys with respiratory disease in South Africa during 1978. The causative agent was isolated and identified as a pneumovirus in 1986. aMPVs have been detected in domestic nonpoultry species in Europe, but tests for the detection of these viruses are not available in the United States. To begin to understa...
Acute respiratory tract infections are leading causes of morbidity in poultry farms throughout the world. Avian pneumovirus (APV), avian influenza virus (AIV), and Newcastle disease virus (NDV) have been recognized as the most important pathogens of both chicken and turkeys. Single-virus reverse transcription-polymerase chain reaction (sRT-PCR) assays are used extensively to detect these viruse...
BACKGROUND Bacterial pneumonia (BP) is an inflammation of the lower airways and lung parenchyma secondary to bacterial infection. The pathogenesis of BP in dogs is complex and the role of canine respiratory viruses has not been fully evaluated. OBJECTIVES The aim of this study was to investigate the occurrence of viral co-infections in dogs with BP and to assess demographic or clinical variab...
