BRSV seroprevalence and associated risk factors on Dutch dairy farms

The Veterinary Journal
Bovine respiratory syncytial virus (BRSV) causes infections of the respiratory tract of cattle and is endemic in the Netherlands. We aimed to update our knowledge on the seroprevalence of BRSV in youngstock on Dutch dairy farms by performing a cross sectional study during the winter of 2021-2022 and a telephone survey with the farmers to map the most ...

Causes of the Abnormally Strong Easterly Phase of the Mesopause Semiannual Oscillation During the March Equinox of 2023 Revealed by a New Reanalysis Data Covering the Entire Middle Atmosphere

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract During the March equinox of 2023, a strong easterly wind of ∼80 m s−1 appeared at an altitude of ∼82 km in the equatorial upper mesosphere, which is regarded as an enhancement of the mesopause semi‐annual oscillation. In this study, a new reanalysis data available up to 110 km was used to investigate its momentum budget.

The Effect of Florfenicol Given by Nebulization in the Treatment of Naturally Infected Calves With Bovine Respiratory Disease Complex: Randomized Clinical Study

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
M. bovis and BRSV were the main pathogens in BRD calves. No PI isolated in any animals. Haematology, haptoglobin levels and thoracic ultrasonography scores were not significant. Reduction in clinical respiratory score was better in nebulized therapy groups after the second day.

Proteome analysis of bronchoalveolar lavage from calves infected with bovine respiratory syncytial virus-Insights in pathogenesis and perspectives for new treatments.

PLoS ONE, 2017
Human and bovine respiratory syncytial viruses (HRSV/BRSV) are major causes of severe lower respiratory tract infections in children and calves, respectively.

Vaccine safety and efficacy evaluation of a recombinant bovine respiratory syncytial virus (BRSV) with deletion of the SH gene and subunit vaccines based on recombinant human RSV proteins: N-nanorings, P and M2-1, in calves with maternal antibodies.

PLoS ONE, 2014
The development of safe and effective vaccines against both bovine and human respiratory syncytial viruses (BRSV, HRSV) to be used in the presence of RSV-specific maternally-derived antibodies (MDA) remains a high priority in human and veterinary ...

Cloning of the transmembrane glycoproteins G and F from a Brazilian isolate of bovine respiratory syncytial virus in a prokaryotic system

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2011
The aim of this work was the cloning of those transmembrane glycoproteins G and F from an isolate bovine respiratory syncytial viruses (BRSV) - a Brazilian isolate of BRSV, named BRSV-25-BR in previous studies, in a prokaryotic system to proceed the ...

Retrospective study of the relative frequency of cattle respiratory disease pathogens in clinical laboratory samples submitted by UK veterinary practices

Veterinary Record, Volume 195, Issue 6, 21/28 September 2024.
Abstract Background The objective of this study was to explore the relative frequency and seasonality of bovine respiratory pathogens in the UK, based on clinical case submission for laboratory PCR testing. Methods This study used retrospective data generated by a central Scotland laboratory using 407 clinical (pooled) samples collected by 95 ...

Cytokine and Acute Phase Response in Calves Following Experimental Infection with BRSV [PDF]

Acta Veterinaria Scandinavica, 2003
Bovine respiratory syncytial virus has been identified as an important pathogen associated with acute respiratory disease in calves. An infection model has been developed reflecting the clinical course and the development of pathological signs during a natural BRSV-infection.

Comparing the immune response to a novel intranasal nanoparticle PLGA vaccine and a commercial BPI3V vaccine in dairy calves [PDF]

, 2015
peer-reviewedBackground There is a need to improve vaccination against respiratory pathogens in calves by stimulation of local immunity at the site of pathogen entry at an early stage in life. Ideally such a vaccine preparation would not be inhibited by
