BACKGROUND: Mycobacterium tuberculosis causes tuberculosis, one of the world’s deadliest diseases. It is an acid-fast bacillus that is 2-4 um in length and 0.2-0.5 um in width. How many weeks, days,& hours would it take to see a M.tuberculosis colony on solid media? Its generation time is listed in the reading (above). Assume that bacterial colonies are not visible to the naked eye unless they contain ≥ 2 millioncells. This species forms aggregates of 5 cells on average. Show your...
