IFNG and tuberculosis: Our results for superiority of BCG for induction of Th1-oriented responses were in agreement with data of KLM+BCG (48) and a TB vaccine candidate (consisted of BCG and Ag85B and ESAT-6 proteins of this bacteria) in mice immunization studies (33) and supported the cytokine results of recent studies on Lag+BCG (34) and FML+BCG (49) for production of moderate levels of IFNγ compared to other vaccine formulations.
