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.

A census to determine the prevalence and risk factors for caprine arthritis-encephalitis virus and visna/maedi virus in the Swiss goat population [PDF]

Preventive Veterinary Medicine, 2017
In Switzerland, viruses belonging to two different phylogenetic groups of small ruminant lentiviruses (SRLV) are currently circulating: the caprine arthritis-encephalitis virus (CAEV) and visna/maedi virus (VMV). In the past two decades, a mandatory national control program has led to a very low prevalence of seropositivity, while completely ...

Pathological, molecular, and serological study of small ruminant lentiviruses in Jordan [PDF]

Veterinary World, 2022
Background and Aim: Maedi-visna is a chronic viral disease of sheep with worldwide distribution causing substantial economic losses to the small ruminant industry. Pneumonia and mastitis are the main manifestations of the disease.

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,

Understanding the Enigmatic Dance of Immune-Mediated Viral Infections and Their Pathogenetic Mechanisms. [PDF]

Vet Med Sci
This graphical representation illustrates the multifaceted nature of the immune response in viral infections, demonstrating both its protective and potentially harmful aspects. While a properly regulated immune reaction facilitates viral clearance and promotes general recovery, an overly robust or misdirected response—exemplified by Type III or Type IV

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.
