Accurate Diagnosis of Small Ruminant Lentivirus Infection Is Needed for Selection of Resistant Sheep through TMEM154 E35K Genotyping

Pathogens, 2021
Small ruminant lentiviruses (SRLV) cause an incurable multiorganic disease widely spread in sheep and goats that disturbs animal welfare and production.

Genetic landscape of Italian SRLV: insights from passive surveillance-based phylogenetic analysis. [PDF]

Front Microbiol
Small ruminant lentiviruses (SRLVs) are retroviruses infecting small ruminants, characterized by a high genetic variability. SRLVs infection may result in a variety of clinical signs in goats and sheep and is not species-specific. SRLVs are worldwide distributed with four distinct genotypes and numerous sub-genotypes described so far.

Immune response dynamics of recent and chronic small ruminant lentivirus infection in the male reproductive system

Semina: Ciências Agrárias, 2023
The objective of this study was to analyze the immune responses of bucks to small ruminant lentivirus (SRLV) with a focus on the reproductive system of males with recent and chronic infection.

Detection of aluminium hydroxide‐induced granulomas in sheep by computed tomography: A feasible approach for small ruminant lentiviruses diagnosis and research

Veterinary Medicine and Science, Volume 7, Issue 5, Page 1757-1761, September 2021., 2021
We describe the usefulness of CT for in vivo diagnose of subcutaneous granulomas in sheep. CT is an excellent tool to advance the diagnosis of subcutaneous Al‐induced granulomas in vivo and to boost further research in SRLV infections in sheep. Abstract Aluminium (Al) hydroxide use as adjuvant induces local formation of long‐lasting subcutaneous ...

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.

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

Case Reports in Veterinary Medicine, Volume 2021, Issue 1, 2021., 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. After that, studies revealed that SRLVs have a broad distribution in Mexico by detecting antibodies or/and molecular tests; however,

Influence of SRLV infections in sheep flocks on growth and reproductive performance [PDF]

Medycyna Weterynaryjna, 2018
The aim of the study was to determine the influence of the occurrence of SRLV infections on lamb growth and reproductive performance of sheep. The study was carried out on 98 sheep flocks from mid-Eastern Poland, covering the area of Lubelskie, Świętokrzyskie and Podkarpackie provinces. The study included 6,470 mother ewes.

Characterization of Ovine A3Z1 Restriction Properties against Small Ruminant Lentiviruses (SRLVs) [PDF]

Viruses, 2017
Intrinsic factors of the innate immune system include the apolipoprotein B editing enzyme catalytic polypeptide-like 3 (APOBEC3) protein family. APOBEC3 inhibits replication of different virus families by cytosine deamination of viral DNA and a not fully characterized cytosine deamination-independent mechanism.

First Molecular Characterization of Small Ruminant Lentiviruses Detected in Romania

Animals, 2023
Small ruminant lentiviruses (SRLVs) are a group of retroviruses that cause multisystem chronic diseases in goats and sheep and lead to production losses in these animals, negatively affecting animal health and welfare. Although molecular characterization
