Bayesian estimation of seroprevalence of small ruminant lentiviruses in sheep from Poland

Preventive Veterinary Medicine, 2017
In Poland, no systematic survey of ruminant lentiviruses (SRLVs) infection was performed, neither at the national nor at the regional level and only limited knowledge exists on the prevalence of SRLVs among sheep. The aim of the present study was to establish the true prevalence of SRLVs infection in sheep from Poland at the animal and herd-levels. The

Small Ruminant Lentiviruses and Caseous Lymphadenitis

Veterinary Clinics of North America: Food Animal Practice
Ovine progressive pneumonia and caprine arthritis encephalitis together are referred to as small ruminant lentiviruses (SRLVs). Along with caseous lymphadenitis (CL), SRLV are 2 of the so-called "iceberg diseases" of sheep and goats. In the case of SRLV, healthy tissue can be replaced with unproductive lymphoid tissue causing loss of milk, poor growth ...

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.

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.

Risk factors associated with seropositivity to small ruminant lentiviruses in goat herds

Research in Veterinary Science, 2013
Cross-sectional studies based on serological testing and questionnaires were conducted at 5-yr intervals (1996, 2002 and 2007) in goat breeding herds from Poland to determine true herd-level seroprevalence of caprine arthritis-encephalitis and the herd-level risk factors for seropositivity.

Small ruminant lentiviruses in Jordan: evaluation of sheep and goat serological response using recombinant and peptide antigens

Tropical Animal Health and Production, 2013
Small ruminant lentiviruses infect sheep and goats worldwide, causing chronic progressive diseases and relevant economic losses. Disease eradication and prevention is mostly based on serological testing.

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.

Molecular characteristics and prevalence of small ruminant lentiviruses in goats in Japan

Archives of Virology, 2017
Small ruminant lentiviruses (SRLVs), which comprise caprine arthritis-encephalitis virus (CAEV) and maedi-visna virus (MVV), are prevalent in goats and sheep worldwide, including in Japan. However, little is known about the molecular characteristics of goat lentiviruses in Japan.

An ELISA Based on Whole Virus for the Detection of Antibodies to Small‐ruminant Lentiviruses

Journal of Veterinary Medicine, Series B, 1994
SummaryA new ELISA kit was developed, based on highly purified whole‐virus antigen derived from the Swiss maedi‐visna virus strain OLV. The sensitivity, specificity and accuracy of this assay were compared with that of an established ELISA based on recombinant GAG (group‐specific antigens)‐GST (glutathione S‐transferase) fusion protein expressed inE ...
