Mycobacteria are a group slow-growing, acid Mycobacterium avium, which can cause very serious infections in children and immune- compromised adults, has a doubling time of 18 hours. A. Would you be able to detect M. avium colonies on solid media 14 days after a viable count was performed? Assume a colony is not visible until it contains at least 1 million cells, that individual CFU were spread on the plate, and that they form clusters of 8 cells (on average). See Chapter 4 for helpful formulas. Show your work. B. Which cytoplasmic or envelope structure would be the best target for a drug that could kill M. avium without disrupting the commensal species of bacteria or harming the human patient? Explain your answer. Draw (in the appropriate color) the appearance of a typical gram positive bacterial coccus after a Gram under brightfield microscopy.
