Human brucellosis is a major health problem in developing countries. A
number of patients with human brucellosis do not recover from the acute stage of
the disease and pass into the chronic form. Since the pathophysiology of this
change is not well understood, we studied the T-cell subsets during the acute,
subacute and chronic forms of human brucellosis. In this study we found
alterations in T-Iymphocyte subsets and in the CD4/CD8 ratio in subacute and
chronic brucellosis while no significant change was found in T-cell subsets in
acute brucellosis. We believe that this alteration of T-cell subsets is important in
the pathophysiology of brucellosis, but it is not clear whether brucella cause this
change or a primary immunodysfunction in patients with a disturbance in T-cell
subset regulation prevents recovery from acute brucellosis and leads to the
development of chronic brucellosis.
