Host Restriction of Lentiviruses and Viral Countermeasures: APOBEC3 and Vif

Viruses, 2013
It is becoming increasingly clear that organisms have developed a variety of mechanisms to fight against viral infection. The viruses have developed means of counteracting these defences in various ways.

Development and comparison of strain specific gag and pol real-time PCR assays for the detection of Visna/maedi virus [PDF]

Journal of Virological Methods, 2010
The aim of this study was the development of gag and pol dual labelled probe real-time PCR and RT PCR assays to quantify the proviral load and the transcripts of the British Visna/maedi virus EV1 strain. Primers and probes were chosen based on the consensus sequences of gag and pol clones representative of EV1 genetic variants.

Histogenesis of the pulmonary lesions in the course of visna maedi virus-induced pneumonia.

Veterinary research, 1996
The major characteristic lesion observed following spontaneous infection of sheep by the prototype lentivirus, maedi-visna virus (MVV), is a lymphocytic intestitial pneumonia. Similar lesions may be observed with variable frequency following infection of other species by pathogenic lentiviruses, for example in children infected by HIV-1.
