The possible utilization of nuclear pockets of lymphocytes in the diagnosis of enzootic bovine leucosis.
A comparative study of the presence of lymphocytosis and nuclear pockets in lymphocytes was carried out using blood samples from animals belonging to herds with bovine enzootic leucosis and from herds free from leucosis. It was found that there was a correlation between the presence of such nuclear projections in a certain percentage of the lymphocytes and a state of lymphocytosis. As this correlation seemed to be independent of the aetiology of the lymphocytosis, it was not considered possible to employ the demonstration of nuclear pockets as a more specific tool in the diagnosis of bovine enzootic leucosis than the lymphocyte counts in themselves.
