Epidemiological Insights into Small Ruminant Lentiviruses in Portuguese Production Systems [PDF]

Animals
Small ruminant lentiviruses are longstanding viral infections affecting sheep and goats worldwide, resulting in reduced efficiency and economic losses. In Portugal, updated epidemiological data are scarce.

Molecular Characterization of Small Ruminant Lentiviruses Isolated from Polish Goats with Arthritis [PDF]

Viruses, 2022
Previous studies revealed that the small ruminant lentivirus (SRLV) population in Poland is highly heterogeneous. All SRLVs detected from Polish sheep and goats so far have belonged to subtypes B1, B2, A1, A5, A12, A13, A16, A17, A18, A23 and A24 ...

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,

Transmission of small ruminant lentiviruses

Veterinary Microbiology, 2004
Small 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.

Testing the Tenacity of Small Ruminant Lentiviruses In Vitro to Assess the Potential Risk of Indirect Fomites’ Transmission [PDF]

Viruses
In 2011–2013, we isolated and characterized small ruminant lentiviruses (SRLVs) from two flocks, one of goats and the other of sheep, that had never been in direct contact. Phylogenetic analysis of these viruses indicated a common origin, which led us to

Risk factors associated with small-ruminant lentiviruses in sheepfold buildings

Annals of Agricultural and Environmental Medicine, 2018
Introduction Small-ruminant lentivirus (SRLV) infection is widespread across Europe. It causes substantial economic losses in sheep breeding. The main route of SRLV infection is through the mother’s milk, especially colostrum However, infection can also ...

Interspecific transmission of small ruminant lentiviruses from goats to sheep. [PDF]

Braz J Microbiol, 2015
Abstrract: This study was conducted in order to evaluate the transmission of caprine lentivirus to sheep using different experimental groups. The first one (colostrum group) was formed by nine lambs receiving colostrum from goats positive for small ...

The genetic variability of small-ruminant lentiviruses and its impact on tropism, the development of diagnostic tests and vaccines and the effectiveness of control programmes [PDF]

Journal of Veterinary Research, 2023
Maedi-visna virus and caprine arthritis encephalitis virus are two closely related lentiviruses which cause multisystemic, progressive and persistent infection in goats and sheep.

Quasispecies Composition of Small Ruminant Lentiviruses Found in Blood Leukocytes and Milk Epithelial Cells [PDF]

Viruses, 2021
Small ruminant lentiviruses (SRLVs) exist as populations of closely related genetic variants, known as quasispecies, within an individual host. The privileged way of SRLVs transmission in goats is through the ingestion of colostrum and milk of infected ...

Genomic heterogeneity of small ruminant lentiviruses detected by PCR

Veterinary Microbiology, 1992
In order to detect a large spectrum of small ruminant lentiviruses, primers for PCR were chosen in conserved parts of the LTR and GAG genes of Icelandic Visna virus 1514 and of the POL gene of caprine arthritis-encephalitis virus. This set of primers was
