Interspecific transmission of small ruminant lentiviruses from goats to sheep
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 ruminant lentiviruses (SRLV). The second group (milk group) was established by nine lambs that received milk of these goats. Third was a control group, consist...
متن کاملPhylogenetic analysis of small ruminant lentiviruses.
Based on available sequence data, a phylogeny of small ruminant lentiviruses (SRLV) was established for env, pol, gag and LTR fragments using maximum likelihood, neighbour-joining and minimum evolution reconstruction techniques. To reconstruct topologies as accurately as possible, phylogenetic parameters like base composition, percentage divergences, kappa, the gamma shape parameter alpha and c...
متن کاملRetroviral Infections in Sheep and Goats: Small Ruminant Lentiviruses and Host Interaction
Small ruminant lentiviruses (SRLV) are members of the Retrovirus family comprising the closely related Visna/Maedi Virus (VMV) and the Caprine Arthritis-Encephalitis Virus (CAEV), which infect sheep and goats. Both infect cells of the monocyte/macrophage lineage and cause lifelong infections. Infection by VMV and CAEV can lead to Visna/Maedi (VM) and Caprine Arthritis-Encephalitis (CAE) respect...
متن کاملComplete Genome Sequences of Two Genotype A2 Small Ruminant Lentiviruses Isolated from Infected U.S. Sheep
Two distinct subgroups of genotype A2 small ruminant lentiviruses (SRLVs) have been identified in the United States that infect sheep with specific host transmembrane protein 154 (TMEM154) diplotypes. Here, we report the first two complete genome sequences of SRLV strains infecting U.S. sheep belonging to genotype A2, subgroups 1 and 2.
متن کاملDirect evidence for natural transmission of small-ruminant lentiviruses of subtype A4 from goats to sheep and vice versa.
Small-ruminant lentiviruses (SRLV), which include the caprine arthritis-encephalitis and the maedi-visna virus, cause persistent inflammatory infections in goats and sheep. SRLV are mainly transmitted from mother to offspring through milk. Transmission after prolonged contact between adult animals has also been observed. The observation that certain SRLV subtypes are found in both goats and she...
