Scientists discovered this novel protein while studying what mechanism in
Hydra? - 🧠 ANSWER ✔✔Skin defenses
3Hydramacin is unique, but appears to be most similar to proteins found in
- 🧠 ANSWER ✔✔Scorpion venom
the Kirby-Bauer disc diffusion test is used to determine: - 🧠 ANSWER
✔✔antimicrobial susceptibility
During incubation, antimicrobials applied to the bacterial lawn become

,concentration on the disc to a lower concentration within the medium via
diffusion)
The area of clearing around the discs is called the zone of: - 🧠 ANSWER
✔✔inhibition (A zone of inhibition is the clear area that develops around a
test bacterium sensitive to the applied antimicrobial agent.)
the diameter of the zone of inhibition is always measured in mm. - 🧠
ANSWER ✔✔The diameter of the zone of inhibition is measured in
millimeters (mm) to determine susceptibility to antimicrobial agents.
Which of the medications tested in the above image is a beta-lactam
antibiotic? - 🧠 ANSWER ✔✔ampicillin(Ampicillin is a semisynthetic penicillin
that targets the cell wall.)
Which of the following medications created the largest zone of inhibition - 🧠
ANSWER ✔✔chloramphenicol (The largest zone of inhibition was
measured at 27 mm around the disc containing chloramphenicol.)
Please evaluate the test organism's sensitivity to chloramphenico - 🧠
ANSWER ✔✔sensitive(The zone of inhibition measured 27 mm for this
drug, which is classified as sensitive to this medication)

, What is the test organism's level of sensitivity to tetracycline? - 🧠 ANSWER
✔✔intermediate( The zone of inhibition measured 15 mm for this
medication, which is classified as resistant to this medication. Less than 14
mm indicates resistance to the medication, while more than 19 mm would
indicate sensitivity to the medication. Please refer to sections 20.1 and 20.4
for additional information)
Based upon the information in the case, hydramacin can be classified as
what type of antibiotic? - 🧠 ANSWER ✔✔broad spectrum ( Hydramacin
appears to be effective against both Gram-positive and Gram-negative
bacteria making it a broad spectrum antibiotic.)
If hydramacin exhibits selective toxicity in experiments, it will - 🧠 ANSWER
✔✔cause no damage to host tissues (A medication exhibiting selective
toxicity kills or inhibits microbial cells but does not cause host cells any
damage. Please refer to sections 20.1 and 20.4 for aditional information)
Hydramacin needs to be tested in human trials - 🧠 ANSWER ✔✔true (One
important phase of testing is to determine if a compound has any toxic
effects on the patient.
