Prevention strategies against small ruminant lentiviruses: An update
Veterinary Journal, 2009 Small ruminant lentiviruses (SRLVs), including maedi-visna virus (MVV) of sheep and caprine arthritis-encephalitis virus (CAEV), are widespread, cause fatal diseases and are responsible for major production losses in sheep and goats. Seventy years after the legendary maedi-visna sheep epidemic in Iceland, which led to the first isolation of a SRLV and ...

The presence of small ruminant lentiviruses in Mexican Pelibuey sheep
Theriogenology, 2016 The transmission frequency of small ruminant lentiviruses (SRLVs) through the placenta is controversial and may be associated with breed susceptibility. In Mexico, SRLV infections in sheep have been poorly studied. This work explores the presence of antibodies and proviral DNA in Mexican Pelibuey sheep. Enzyme-linked immunosorbent assays (ELISAs; three

Update on Small Ruminant Lentiviruses
Veterinary Clinics of North America: Food Animal Practice, 2021Small ruminant lentiviruses (SLRVs) have been recognized throughout the world for decades. SLRVs are a heterogenous group of viruses that can infect sheep, goats, and wild ruminants. Evidence supports cross-species infection. These viruses cause lifelong infections where they target specific organs, which can result in production losses due to ...

Phylogenetic analysis of small ruminant lentiviruses detected in Slovenia
Veterinary Microbiology, 2013Small ruminant lentiviruses (SRLV), which belong to the Retroviridae family, infect goats and sheep worldwide. The aim of this study was to characterize the SRLV strains circulating in Slovenia, by phylogenetic analysis of two genomic regions, 1.8 kb gag-pol fragment and 1.2kb pol fragment.

Transmission of small ruminant lentiviruses
Veterinary Microbiology, 2004Small ruminant lentiviruses (SRLV) are classical slow retroviruses causing chronic inflammatory disease in a variety of target organs. The routes of transmission have been investigated and a large body of evidence has accumulated over many years.

Phylogenetic analysis of small ruminant lentiviruses from Southern Brazil
Virus Research, 2001The first lentivirus isolated from sheep in Brazil was analysed phylogenetically. Evolutionary trees of the proviral 597 nucleotide gag and 432 nucleotide pol sequences obtained by the maximum likelihood method demonstrated that the sheep isolate clustered with prototype Maedi Visna virus whereas three lentiviruses isolated from goats in the same ...

Diagnostic tests for small ruminant lentiviruses
Veterinary Microbiology, 2005Maedi visna virus and caprine arthritis encephalitis virus are closely related retroviruses that cause chronic inflammatory disease in small ruminants. The infections are characterised by insidious onset and slow progression. Diagnosis of infection is usually by serological testing.

Genetic analysis of small ruminant lentiviruses following lactogenic transmission
Virology, 2010 Lactogenic transmission plays an important role in the biology of lentiviruses such as HIV and SIV or the small ruminant lentiviruses (SRLV). In this work we analyzed the characteristics of viruses that goats, naturally infected with two strains of SRLV, transmitted to their kids.
