Perivascular inflammatory cells in ovine Visna/maedi encephalitis and their possible role in virus infection and lesion progression

, 2012
6 Páginas.We examined the distribution in the perivascular spaces of Visna/maedi antigen, T cells (CD3+, CD4+ and CD8+), B cells and macrophages by immunohistochemistry in 22 natural cases of Visna/maedi encephalitis.

Soroprevalência da infecção por lentivírus de pequenos ruminantes em abatedouros do estado de Pernambuco, Brasil

Arquivos do Instituto Biológico, 2016
RESUMO: A soroprevalência da infecção por lentivírus de pequenos ruminantes (LVPR) foi determinada em amostras de soros sanguíneos de caprinos e ovinos de aptidão cárnea provenientes de abatedouros de dez municípios do estado de Pernambuco, Brasil.

Maedi visna - genetic aspects of susceptibility/resistance in sheep

, 2019
The aim of this research is to evaluate the rate of correlation between Maedi-visna sheep disease and the polymorphism on 35th position of the gen for TMEM154 transmembrane protein.

Mimicry of a 21.5 kDa myelin basic protein peptide by a Maedi Visna virus polymerase peptide does not contribute to the pathogenesis of encephalitis in sheep

, 1996
Epitope mimicry is the theory that an infectious agent such as a virus causes pathological effects via mimicry of host proteins and thus elicits a cross-reactive immune response to host tissues.

Evaluation of approaches to control of Maedi-Visna disease of sheep using a Markov chain simulation model for a range of typical British Flocks

An epidemiological model is described that closely mimicked results of a published serological study of natural transmission of Maedi-Visna virus in a low ground flock of sheep.

The effects of maedi-visna virus infection on productivity in ewes

Five sets of data from four separate sheep flocks (1445 ewes) were used to assess the effects of subclinical maedi-visna virus infection (as determined by serological procedures) on productivity in ewes.
