Aid to the antemortem diagnosis of Fell pony foal syndrome by the analysis of B lymphocytes

摘要

Fell pony foals are affected by a congenital fatal immunodeficiency that commonly leads to anaemia and lymphopenia. Previous work has shown that the foals' circulating subpopulations of CD4 and CD8 T lymphocytes are unaffected. in this study it was shown that the mean population of B lymphocytes in 10 affected foals was less than 10 per cent of that in normal foals.
