Presence of a unique parainfluenza virus 3 strain identified by RT-PCR in visna-maedi virus infected sheep

Veterinary Microbiology, 1997
The presence in farm sheep of a paramyxovirus closely related to parainfluenza virus type 3 (Pi3) from humans or cattle was confirmed using RT-PCR on RNA samples from lung cells from slaughtered animals. Sequencing and restriction enzyme patterns of the amplified fragment of the F gene confirms the distinctness of the isolate, and suitable PCR primers ...

Visna-maedi Virus Induces Interleukin-8 in Sheep Alveolar Macrophages through a Tyrosine-kinase Signaling Pathway

American Journal of Respiratory Cell and Molecular Biology, 1998
The mechanisms leading to the severe lung damage seen in some sheep naturally infected with the visna-maedi virus, and to pulmonary lesions in other lentiviral diseases, appear to involve the recruitment of large numbers of uninfected inflammatory cells.

Alveolar macrophages from sheep naturally infected by visna-maedi virus contribute to IL-8 production in the lung

Veterinary Immunology and Immunopathology, 1997
Sheep naturally infected by visna-maedi virus often develop a chronic interstitial lung disease characterized by an alveolitis comprising lymphocytes, neutrophils and macrophages. The alpha chemokine interleukin-8 (IL-8) was detected in cell free bronchoalveolar lavage fluid from naturally infected animals, confirmed by RT-PCR, presenting typical ...

Pathogenesis of visna/maedi and caprine arthritis-encephalitis: New leads on the mechanism of restricted virus replication and persistent inflammation

Veterinary Immunology and Immunopathology, 1987
Lentiviruses are unique retroviruses which cause diseases with long incubation periods and prolonged clinical courses. The prototype lentiviruses, visna/maedi of sheep and arthritis-encephalitis virus of goats (CAEV), infect cells of the monocyte-macrophage system and replicate at a restricted level in these cells.

Indagine sierologia riguardante la diffusione del virus Visna/Maedi (MVV) in allevamenti ovini in Italia

1999
SUMMARY - In order to gel a generai indication of thè extent of maedi-visna infection in dairy and meat sheep flocks in Italy, a wide serological survey covering flocks in several provinces was carried out in 1998. Blood samples were obtained through thè courtesy of veterinary surgeons involved in testing flocks for brucellosis.
