An outbreak of small ruminant lentivirus in a Swedish dairy goat herd

Veterinary Record Case Reports, Volume 11, Issue 4, December 2023., 2023
Abstract Small ruminant lentivirus causes severe economic losses, and negatively affects animal welfare in goat herds across the world. The aim of this study was to describe the clinical and pathological consequences of the disease in an affected goat herd, as well as to sequence the virus in infected animals. Seventy‐six percent of the sampled animals

Multiple infections of zoonotic pathogens in wild Brandt's voles (Lasiopodomys brandtii)

Veterinary Medicine and Science, Volume 9, Issue 5, Page 2201-2211, September 2023., 2023
Our research revealed the viral and bacterial diversity in wild Brandt's voles. The characterization and distinctive lineage of some rodent‐specific viruses (Cytomegalovirus, PestVs and Lentiviruses) and rodent‐borne bacteria (Leptospira interrogans and Vibrio cholerae) indicates that wild Brandt's voles may harbor a diversity of viruses and bacteria ...

Associations between small ruminant lentivirus infection and total milk yield and somatic cell count in a dairy sheep flock

Veterinary Record, Volume 192, Issue 11, 3/10 June 2023., 2023
Abstract Background Small ruminant lentiviruses (SRLVs) are lentiviruses of sheep and goats, formerly known as maedi–visna (MV) in sheep and caprine encephalitis and arthritis in goats. In sheep, SRLVs commonly cause progressive pneumonia, wasting and indurative mastitis.

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.
