Immunological responses of Balb/C mice infected with Mycobacterium tuberculosis MT103 and M. tuberculosis SO2: mean ± s.d. values of quantitative expression of mRNA encoding cytokines and nitric oxide synthase (iNOS) determined by real-time polymerase chain reaction (PCR) in lung homogenates from three mice per group infected with either M. tuberculosis MT103 or M. tuberculosis SO2. Asterisks represent statistical significance between groups at those time-points (P < 0·05).
