esc ock Question 4 0/7.7 points Here we see 2 sets of plates that have been exposed to UV light. The two plates on the left are bacteria "A" with exposure of UV light at 20 seconds and 60 seconds respectively. The two plates on the right are bacteria "B" with exposure of UV light at 20 seconds and 60 seconds respectively. Which bacteria is killed by UV light at 20 seconds?

Disinfectant A because there is no halo around the disc Disinfectant G and B are equally good Question 8 0/7.7 points A new disinfectant has come out on the market. "Zippity Do It claims to be the best disinfectant on the market. You used 3 bacteria that would be found in any bathroom to test "Zippity Do It" against Lysol and Bleach. The results of disinfectants are placed on the chart below. The result is showing the measurement of the Zone of Inhibition. Is "Zippity Do It the best overall disinfectant? Why? The wwwww Feve T Time I would need an interpretive chart to know for sure No, it was not most effective against any of the bacterium tested Yes, it showed the best measurement for E. coll It was the worst against E. coli
It tells us if a drug is sensitive to several bacteria Question 10 0/7.7 points We are looking for a drug to kill the pathogen causing an infection in our patient. We tested Tetracyline, an antibacterial drug, with a sample taken from a patient. The Zone of Inhibition for Tetracyline was measured to be 6mm. When we compared it to an interpretive chart, we found that the 6mm fit under the Resistant column on the chart. What does that tell us about this drug? The pathogen is sensitive to Tetracycline: Tetracycline is sensitive to the pathogen. The pathogen is resistant to Tetracycline. Question 11 0/7.7 points We tested antibiotics for a bacterium, meas the zone of inhibition for each drug and placed them on the chart below. Using this chart that contains the interpretive chart, which drug would be the most effective? Why? At one of Resistant ermediate Serve Dig 1 besparyn 1300 Kampin 354 431 4EE ATE 1517 1234 Dur 115 30514 12-15 Penicillin G is most effective because it has the largest zone of inhibition size Tetracycline and Penicillin G would both work because they both fall in the sensitive column Streptomycin is most effective because it matches the size of the resistant column Kanamycin is most effective because it has the smallest zone of inhibition size M
Question 13 0/7.7 poin As we studied antibiotics, we were able to see that Penicillin is a drug that inhibits the gram positive cell from producing the peptidoglycan of the cell wall. We tested antibiotics for E. coli and Bacillus cereus. Penicillin worked against Bacillus but not E. coli - from what you know about Bacillus from lecture, would you expect Penicillin to be an effective drug against Clostridium tetani? Why? Penicillin should have worked with E. coli because it is gram positive like Bacillus Penicillin would not work because Bacillus and Clostridium are not the same genus There is no way to tell without testing Clostridium tetani. I would expect Penicillin to work because both of these are gram positive bacteria
