Each of the animals was infected with Mtb CDC1551. The animals were either vaccinated and/or immunized or considered a negative control. Immunizations consisted of the recombinant 3D–BCG strain provided by Dr. Doug Kernodle. The animals vaccinated with the 3D–BCG strain were boosted six weeks later with either a control MVA or MVA:Ag85B and then challenged six weeks after the boost with Mtb CDC1551 to deliver 1000 cfu into the lungs of macaques (86). Aerosol vaccination with a single, one time dose of BCG (Danish) (130, 131) as well as Mtb:Δ-sigH (CDC1551 background) [140] were performed in order to deliver ∼5000 cfu of bacilli into the lungs of macaques. The animals were challenged 8 weeks after the single pulmonary vaccination with the identical dose of Mtb CDC1551 (1000 cfu delivered into the lungs of macaques). SIV co-infection was performed 9 weeks after initial low-dose (25–50 cfu delivered to the lungs of macaques) Mtb CDC1551 infection.
