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.

Etiology, Epizootiology and Control of Maedi-Visna in Dairy Sheep: A Review

Animals, 2020
Maedi-visna (MV) in sheep is caused by maedi-visna virus (MVV), a small ruminant lentivirus (SRLV) that causes chronic infection and inflammatory lesions in infected animals.

Effects of housing on the incidence of visna/maedi virus infection in sheep flocks [PDF]

Research in Veterinary Science, 2010
The incidence of seroconversion to visna/maedi virus (VMV) infection and its relationship with management and sheep building structure was investigated in 15 dairy sheep flocks in Spain during 3-7years. Incidence rates were 0.09 per sheep-year at risk in semi-intensive Latxa flocks and 0.44 per sheep-year at risk in intensive Assaf flocks and was ...

Visna/maedi virus serology in sheep: Survey, risk factors and implementation of a successful control programme in Aragón (Spain) [PDF]

The Veterinary Journal, 2010
A serological survey of Visna/maedi virus (VMV) infection involving 274,048 sheep from 554 flocks was undertaken during 2002-2007 in Aragón, North-East Spain. One hundred and two of these flocks enrolled in a VMV control programme to reduce seroprevalence by selecting replacement lambs from seronegative dams and gradual culling of seropositive sheep ...

Visna/Maedi virus genetic characterization and serological diagnosis of infection in sheep from a neurological outbreak

Veterinary Microbiology, 2012
An extensive outbreak characterized by the appearance of neurological symptoms in small ruminant lentivirus (SRLV) infected sheep has been identified in Spain, but the genetic characteristics of the strain involved and differential diagnostic tools for this outbreak remain unexplored.

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.
