[New findings on the immunology of bronco-82]

The effect of Bronco-82 treatment, a bacterial polyvalent vaccine, was determined on some of the most significant parameters of the immune response, i.e. PHA-induced blastogenesis, secretory IgA levels, IL 2 receptor expression, human T-cell activation antigen (MLR 3) and gamma-interferon production. The results obtained pointed out a high immunostimulating activity of the vaccine on the parameters considered. Some aspects of the complex immunomodulating effects of Bronco-82 are discussed.
