  • This amplicon was Not I-digested and cloned into the Not I site of the pHIP1 plasmid containing the xylE gene to generate pHIP4.

  • In experiments in which THP-1 cells were infected at a MOI of 50:1 (results in ~1 phagocytosed M. smegmatis bacterium per macrophage) with a mixture containing equal numbers of bacteria of the xylE -expressing control strain and a strain carrying the cosmid vector pYUB178, the ratio of recovered white colonies to yellow colonies was 1:1 at all time points (data not shown).

  • For the screening step, we used the xylE gene because catechol 2,3 dioxygenase activity is easily measured by spraying colonies with catechol and the amount of color produced is a rough measure of promoter activity [ 10 ] . In our screen, white, pale yellow, and bright yellow colonies were observed, indicating a wide range of promoter activity.

  • In coinfection experiments with xylE -expressing bacteria, both sur2 and sur3 bacteria exhibited increased survival (Figure 3).

  • In this coinfection, the ratio of white (sur2) to yellow (xylE and Rv0365c expressing) colonies remained 1:1 through 12 hours and then increased to ~3:1 at 24 hrs, consistent with the above-described observations.
