Problem 1. (5 pts Mycobacteria are a group of slow-growing, acid-fast bacili. 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. Yes/No 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. Problem 2. (1 pt) Draw (in the appropriate color) the appearance of a typical gram- positive bacterial coccus after a Gram stain under brightfield microscopy.
