  1. Great video! I was just wondering what's the name of the program you used to make this video? Does anyone know?

  2. Can someone explain it a little deeper in regards to "I recognize this/i dont recognize this"? I know how a normal infection becomes latent, but why does the t-cells not activate otherwise? Shouldn't it react the same as if there was a whole bacteria or is it because we're only putting in tuberculin?

  3. Just wondering, if the same person goes for a TCT/PPD test for the second time, would he show positive results due to the first PPD generating memory of the encounter??
