Failure to detect Schmallenberg virus RNA in ram semen in the UK (2016–2018)

Veterinary Record Open, Volume 9, Issue 1, December 2022., 2022
Abstract Background Schmallenberg virus (SBV) is a midge‐borne arbovirus that first emerged in the European ruminant population in 2011 and has since settled to an endemic pattern of disease outbreaks on an approximately 4‐year cycle when herd immunity from the previous circulation drops to a point allowing renewed widescale virus circulation.

To scan or not to scan? Efficacy of transthoracic ultrasonography for ovine pulmonary adenocarcinoma screening in a large commercial UK sheep flock

Veterinary Record, Volume 191, Issue 3, 6/13 August 2022., 2022
Abstract Background Transthoracic ultrasonography (TTUS) is currently the only widely used method to diagnose preclinical or subclinical ovine pulmonary adenocarcinoma (OPA) in the live sheep. However, little is known about the test characteristics of TTUS.

Association of Ovar‐DRB1 alleles with innate immune responses in sheep

Veterinary Medicine and Science, Volume 8, Issue 2, Page 752-757, March 2022., 2022
Results of this study provided additional support for the association between Ovar‐DRB1 alleles and regulation of immune responses in sheep population. Description of MHC polymorphism and its role in the controlling of immune responses will increase our understanding of host‐pathogen interactions, and ultimately facilitate the selection of disease ...

A novel enterovirus in lambs with poliomyelitis and brain stem encephalitis

Transboundary and Emerging Diseases, Volume 69, Issue 2, Page 227-234, March 2022., 2022
Abstract An Austrian organic dairy sheep farm experienced cases of recumbency and sudden deaths in 3‐ to 4‐week‐old lambs. Two animals were subjected to thorough clinical and pathological investigations. Pathohistological analysis identified severe nonsuppurative myelitis and mild nonsuppurative encephalitis.

Visna in a UK flock and the biosecurity risk arising from the onward sale of likely infected pedigree stock

Veterinary Record Case Reports, Volume 9, Issue 3, September 2021., 2021
Abstract Small ruminant lentivirus infections in sheep most commonly present with respiratory signs (maedi) and indurative mastitis, while primary neurological signs (visna) have rarely been reported in Great Britain (GB). Most reports of visna describe signs referable to myelitis, although central signs associated with encephalitis may feature.

Pestivirus apparent prevalence in sheep and goats in Northern Ireland: A serological survey

Veterinary Record, Volume 188, Issue 1, January 2021., 2021
Abstract Background: Bovine viral diarrhoea virus (BVDV) and border disease virus (BDV) can cause significant health problems in ruminants and economic impacts for farmers. The aim of this study was to evaluate pestivirus exposure in Northern Ireland sheep and goat flocks, and to compare findings with a previous study from the region. Methods: Up to 20

A Seroprevalence Survey of Maedi-Visna Among Twenty-Four Ovine Floks from Twelve Regions of China

Journal of Integrative Agriculture, 2013
Maedi-visna virus (MVV) is an ovine lentivirus that is widespread in many countries worldwide. Both clinical and subclinical MVV infections cause substantial economic losses.

Comparison of immunoassay and real-time PCR methods for the detection of Jembrana disease virus infection in Bali cattle [PDF]

, 2009
A sensitive diagnostic assay for the detection of infections with the bovine lentivirus Jembrana disease virus (JDV) is required in Indonesia to control the spread of Jembrana disease. Immunoassays are used routinely but are compromised by cross-reactive

Study of compartmentalization in the visna clinical form of small ruminant lentivirus infection in sheep [PDF]

, 2012
Background A central nervous system (CNS) disease outbreak caused by small ruminant lentiviruses (SRLV) has triggered interest in Spain due to the rapid onset of clinical signs and relevant production losses.
