Phylogenetic analysis of small ruminant lentiviruses from Southern Brazil

Virus Research, 2001
The 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 ...

First partial characterisation of small ruminant lentiviruses from Greece

Veterinary Microbiology, 2005
Small ruminant lentivirus (SRLV) infections are widespread in Greece, but SRLVs have never been isolated and characterized. In this study, we present the sequence of a 574-nucleotide (191-amino acid) region of the gag gene of SRLV strains from four sheep and one goat from a single geographic area of Greece.

Phylogenetic analysis of small ruminant lentiviruses detected in Slovenia

Veterinary Microbiology, 2013
Small 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.

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 tested in six different caprine arthritis-encephalitis virus (CAEV)- and Maedi-Visna virus isolates

Seroprevalence of caseous lymphadenitis, Mycobacterium avium subsp. paratuberculosis and small ruminant lentiviruses in U.S. domestic sheep and goat herds

American Association of Bovine Practitioners Conference Proceedings
Historically, caseous lymphadenitis (CL), Mycobacterium avium subsp. paratuberculosis (MAP) and small ruminant lentiviruses (SRLV) have been the most common diseases tested for in sheep and goats.

Serotyping versus genotyping in infected sheep and goats with small ruminant lentiviruses

Veterinary Microbiology, 2021
Despite SRLV infection being endemic in Mexico, there is little information regarding which genotypes are present. We compared serotyping and PCR-sequencing results from sheep and goats infected with SRLV. We separated plasma and peripheral blood leukocytes (PBL) from 1940 blood samples from sheep and goats from 12 states across Mexico.

Molecular and genetic characteristics of small ruminant lentiviruses in Slovenia

Acta Veterinaria Hungarica, 2013
Small ruminant lentiviruses (SRLV) are spread throughout the world, including Slovenia, where the first evidence of caprine arthritis encephalitis virus (CAEV) infection was found in 1996. This study was conducted to investigate the molecular and genetic characteristics of SRLV infection in Slovenia in order to classify our strains in relation to other

Immortalization of caprine fibroblasts permissive for replication of small ruminant lentiviruses

American Journal of Veterinary Research, 1997
Abstract Objective To establish immortalized caprine fibroblastic cell lines permissive for replication of small ruminant lentiviruses. Animals Carpal synovial membrane explants collected aseptically from a surgically delivered fetus of a lentivirus-seronegative goat.

A highly sensitive semi-nested real-time PCR utilizing oligospermine-conjugated degenerate primers for the detection of diverse strains of small ruminant lentiviruses.

Molecular and Cellular Probes, 2020
Small ruminant lentiviruses (SRLVs) are highly diverse retroviruses infecting sheep and goats. Although PCR-based testing is being utilized for diagnostics, its application is hampered by various factors.
