Exploration of the cellular mediated immunity by the blastogenesis test during chronic brucellosis in human

The diagnosis of the chronic, human brucellosis is frequently difficult and usually needs experimental methods. This paper describes a lymphocyte stimulation test with a Brucella antigen and the results of this test concerning 45 brucellic or not brucellic patients. It is concluded that this test is interesting, especially for the chronic and sero-negative Brucellosis diagnosis.
