Bacteria Traits

Why is it possible for bacterial cells to obtain new genetic traits while humans cannot? Would it ever be possible for human cells to undergo conjugation? Why or why not?

Given what you know about genetic recombination in bacteria, do you think it is possible for the medical community to stay ahead of antibiotic resistance? Why or why not?

How do humans contribute to the development of resistance to antimicrobial drugs?

1.What does it mean for a bacterium to be âantibiotic resistantâ? In your opinion, what factors have led to the development of antibiotic resistant bacteria?

2. How does Penicillin work? In what other ways might Penicillin (and similar drugs) be used to inhibit a bacteriumâs ability to cause infection or persist in a host? (HINT: Think about the other structural features of a bacterium)

3. Antibiotic resistance is a serious threat to human health. What role do beta-lactamases have in increasing bacterial resistance to drugs such as penicillin? In the future, do you feel we will be able to âsolveâ the antibiotic resistance problem?

MUST BE IN YOUR OWN WORDS!!!!

You must be thinking right now, what is a superbug? Is it a tenfoot tall mutated form of a flying two-headed cockroach? Actually,you cannot see superbugs with the naked eye. Superbugs have comeabout by way of overuse and abuse of antibiotics and yet the termstill sounds like a cheap Hollywood Science-fiction horrorflick.

Have you ever wondered how antibiotics actually work? They candifferentiate your human cells from bacterial cells. Penicillinprevents bacterium from building a cell wall; animal cells do nothave cell walls. The first antibiotic (penicillin) was discoveredin the 1920s by Alexander Fleming. It wasnât until the 1940s thatit was commercialized. The delay was caused by difficulty inproducing appropriate quantities. By the time it wascommercialized, Methicillin-resistant Staphylococcusaureus (MRSA) was identified as resistant. In fact, whenaccepting his Nobel prize, Fleming cautioned the scientificcommunity on antibiotic resistance. In 1959, resistant Shigellashowed resistance to tetracycline. In 1962, MRSA was found to beresistant to methicillin. This same bacteria developed resistanceto linezolid in 2001, vancomycin in 2002, and ceftaroline in 2011.Ceftaroline was only on the market for one year before resistancewas identified. According to the Center for Disease and Control(CDC), 23,000 deaths have been caused by antibiotic resistance(CDC, 2018).
