  • Seven of these ORFs have high identity to proteins essential for basic cellular processes, including replication, in other mycobacterial species (Table 1).

  • To elucidate the mechanisms used by tubercle bacilli to survive in macrophages, researchers at several laboratories are studying mycobacterial genes specifically expressed during growth in macrophages [ 1 2 3 4 5 6 ] . Among the genes specifically expressed during intracellular growth are genes encoding two extracytoplasmic function sigma factors, SigE (σ E) and SigH (σ H) [ 3 4 5 ] .
