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 ...

Genetic Characterization of Small Ruminant Lentiviruses (SRLVs) Circulating in Naturally Infected Sheep in Central Italy [PDF]
Viruses, 2022 Small ruminant lentiviruses (SRLVs) represent a very heterogeneous group of ss-RNA viruses that infect sheep and goats worldwide. They cause important, deleterious effects on animal production and limit the animal trade.

Genotyping Based on the LTR Region of Small Ruminant Lentiviruses from Naturally Infected Sheep and Goats from Mexico. [PDF]
Biomed Res Int, 2019 Small ruminant lentiviruses (SRLVs) belong to the genus Lentivirus in the Retroviridae family. There are five genotypes (A, B, C, D, and E), where genotypes A and B have a global distribution and genotypes C, D, and E are limited to Europe. The presence of SRLV has been confirmed in Mexico, with genotype B detected in the central region of the country.

Duration of passive immunity to small ruminant lentiviruses in lambs
Semina: Ciências Agrárias, 2014 In order to evaluate the passive immunity against small ruminant lentiviruses (SRLV) in lambs, this study was conducted from two experimental groups. The first one (G1) was established by nine lambs subjected to artificial feeding of colostrum of goats ...

Emergence and pandemic spread of small ruminant lentiviruses. [PDF]
Virus Evol, 2023 Abstract Small ruminant lentiviruses (SRLVs) cause chronic, persistent infections in populations of domestic sheep (Ovis aries) and goats (Capra hircus) worldwide. The vast majority of SRLV infections involve two genotypes (A and B) that spread in association with the emergence of global livestock trade.
