Abstract:
Bone-marrow samples were collected from 48 CAEV-seropositive, symptomless goats (30 kids, 18 adults).
The samples were formalin-fixed and processed for histological examination. In addition, all samples
were examined immunohistochemically with a monoclonal antibody (1A7) against the p27 capsid protein
of maedi-visna virus, an antibody which cross-reacts with the Ca-p27 of CAEV. Samples from 16 goats
(10/30 kids, 6/18 adults) showed positive immunolabelling of bone-marrow stromal cells (fibrocytes,
endothelial cells and adipocytes) and of scattered macrophages, whereas haematopoietic cells were
negative. The detection of viral Ca-p27 protein in bone-marrow fibrocytes was consistent with previous
in-vitro studies which indicated that such cells are semi-permissive for CAEV infection. It is speculated that
bone-marrow stromal cells represent a viral reservoir in symptomless animals
