Breed susceptibility to ovine progressive pneumonia (maedi/visna) virus
Veterinary Microbiology, 1986In this retrospective study of breed differences in susceptibility to disease caused by ovine progressive pneumonia (OPP) virus, 29 Border Leicester sheep were compared with 46 Columbia sheep. As judged by frequency and severity of clinical signs and lesions attributable to the infection, Border Leicester sheep were markedly more susceptible than ...

Expression of the SU glycoprotein of maedi visna virusin baculovirus
Archives of Virology, 1997The envelope glycoprotein, gp 135, of the ovine lentivirus maedi visna virus is the main target for a specific antibody response in vivo, however, little is known about the specific regions of gp 135 which elicit this response. Research on the function of gp 135 has been hampered by the lack of reagents to study such structure/function relationships ...

Immune responses to maedi-visna virus
2018Maedi-visna infected sheep develop detectable levels of anti-viral antibody by 4-6 weeks after experimental infection. These antibodies are directed against the envelope and core structural proteins of the virus and initially are of the IgM isotype, but later switch to IgG. These IgG anti-visna antibodies are restricted to the IgGj subclass.

Respiratory transmission of maedi-visna virus
2018The main routes of transmission of Maedi-visna virus (MVV), an ovine lentivirus, are thought to be through ingestion of infected colostrum and/or milk, or inhalation of respiratory secretions. Whereas oral transmission appears to be mediated via uptake ofvirus by small intestinal epithelial cells, the mechanism of virus uptake in the respiratory tract ...

Regulation of transcription in Maedi-visna virus
2018Due to the apparent requirement for integration in the lentiviral lifecycle these viruses behave essentially as cellular genes. However they have the great advantage of containing all their regulatory elements within a defined sequence of DNA which can be readily manipulated in vitro.
