Abstract
The effect of tuberculosis anergic immune sera adsorbed with BCG was studied on cocultures of adherent and non-adherent cells from PPD+ tuberculosis patient (TBP PPD+). This effect on the cocultures was quantified by lymphocyte transformation (LT) test using PPD as antigen. Only those cocultures with non-adherent cells from TBP PPD+ patients treated with anergic sera, inhibited the LT response induced by PPD, whereas sera adsorption with BCG eliminated the inhibitory effect.
