According to this book, dead TB can cause tuberculosis. There's also a lot of information in the book about the effect of sunlight on bacteria. I read in at least one place that about a hundred years ago, you could go into major cities, collect dust in public places and find TB in the dust. TB could also be found in the dirt and dust in the streets and street sweepers had high rates of TB.

Here you can see a lot of paper patents you had to search before they put everything on computer databases. There were some patents going back to the 1800's and there was a lot of dust on the patents. I had an idea that there might be TB in the hundred year old dust. It would be dead by now, but if TB was in it then it might cause tuberculosis in anyone who searched these patents regularly. Two patent searchers told me they had TB skin tests and tested negative. One of them got the skin test after he had a chest x-ray after being hit by a car and the other one got a TB skin test once a year because he did counselling in a hospital.
