Ovine Progressive Pneumonia: Diagnosis and Seroprevalence in the South of Sonora, Mexico

Case Reports in Veterinary Medicine, 2021
Ovine progressive pneumonia (OPP) is the most severe presentation of small ruminant lentivirus (SRLV) infection known as Maedi-Visna. Serological evidence in Mexico of the presence of this lentivirus was published in 1986.

Seroprevalence of Visna-Maedi Virus (VMV) and Border Disease Virus (BDV) in Van province and around [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2018
The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van.

Ovine TRIM5α can restrict visna/maedi virus. [PDF]

J Virol, 2012
ABSTRACT The restrictive properties of tripartite motif-containing 5 alpha (TRIM5α) from small ruminant species have not been explored. Here, we identify highly similar TRIM5α sequences in sheep and goats. Cells transduced with ovine TRIM5α effectively restricted the lentivirus visna/maedi virus DNA synthesis.

Recombinant CA Protein-Based ELISA for Serological Detection of Small Ruminant Lentiviruses Antibodies. [PDF]

Transbound Emerg Dis
Maedi‐visna (MV) and caprine arthritis encephalitis (CAE) are important viral diseases of sheep and goats. The diseases are caused by a group of genetically closely related lentiviruses known as small ruminant lentiviruses (SRLV), and are collectively referred to as SRLV infections. As the majority of sheep and goats infected with SRLV are asymptomatic,

Role of alveolar macrophages in respiratory transmission of visna/maedi virus. [PDF]

J Virol, 2008
ABSTRACTA major route of transmission ofVisna/maedi virus(VMV), an ovine lentivirus, is thought to be via the respiratory tract, by inhalation of either cell-free or cell-associated virus. In previous studies, we have shown that infection via the lower respiratory tract is much more efficient than via upper respiratory tissues (T. N.

Identification of the ovine mannose receptor and its possible role in Visna/Maedi virus infection. [PDF]

Vet Res, 2011
Abstract This study aims to characterize the mannose receptor (MR) gene in sheep and its role in ovine visna/maedi virus (VMV) infection. The deduced amino acid sequence of ovine MR was compatible with a transmembrane protein having a cysteine-rich ricin-type amino-terminal region, a fibronectin type II repeat, eight tandem C-type lectin ...

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.
