(A) Phagocytic index of BMDM infected with wild-type or Tx5 N. brasiliensis. (B) Number of CFU obtained in BMDM cultures infected with wild-type and Tx5 N. brasiliensis after several time intervals. (C) Number of CFU in IFN-γ-activated BMDM, infected with wild-type or Tx5 N. brasiliensis. (D) NO production in IFN-γ-activated BMDM, in response to infection with wild-type or Tx5 N. brasiliensis. (E) NO production by IFN-γ-activated BMDM stimulated with several concentrations of isolated N. brasiliensis wall-associated lipids. (F) Total number of CFU in cultures of BMDM stimulated with several concentrations of wall-associated lipids, activated with IFN-γ, and then infected with wild-type or Tx5 N. brasiliensis. Data are expressed as means ± standard deviations. *, P < 0.05; ***, P < 0.0001, as assessed using a Bonferroni posttest.
