Controlled mycobacterial infection is distinguished from progressive infection by higher induction of Th2 markers.

<p>The groups with different bacterial loads were analyzed for typical Th2 (A–F) and Th1 (G–J) markers by q-RT-PCR at 4 wpi. (K) The ratio of the inductions of <i>il13</i> to <i>ifnγ</i> was also calculated in the different subgroups at 4 wpi.
