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.

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.

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
