Question
1.
A. Based on the result, disk D is least potent antibiotic. This is because this disk have least zone of inhibition which is shown by diameter around the disc. Therefore, this show that antibiotic is not able to kill bacteria around it.
B. Based on these result, no it is not correct to say that Disc A is more potent antibiotic. This is because disc C is having largest diameter around disc that correlate with effectiveness of antibiotics.
Add Answer to:
1. A) Based on these results, which disk is the least potent antibiotic among those tested?...

Triple Antibiotic Ointment contains Neomycin, Polymyxin B and Bacitracin and is sold across the counter to be applied topically to cuts and abrasions. This ointment is used to prevent infection and aid healing. Based on the results obtained using the Kirby-Bauer disk diffusion susceptibility test, would this ointment prevent infection by all four of the bacteria tested? Explain. the four bacteria are Staphylococcus aureus Escherichia coli Bacillus subtilis Pseudomonas aeruginosa

Epidemiology: Among those who are 25 years of age, those who have been driving less than 5 years had 13,700 motor vehicle accidents in 1 year, while those who had been driving for more than 5 years had 21,680 motor vehicle accidents during the same time period. It was concluded from these data that 25-year-olds with more driving experience have increased accidents compared to those who started driving later. This conclusion is: Select one: a. Correct based on the data...

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...

12 Two packaging styles for a new cookie brand were tested in 20 grocery stores for one week. Ten of these stores were randomly chosen to be stocked with packages of style #1, while the other ten were stocked with packages of style #2. Marketing researchers determined that one style would prove to be clearly better than the other if its median number of packages sold exceeded that of the other by at least 10. Based on this reasoning and...

The total electric field at a point on the axis of a uniformly charged disk, which has a radius R and a uniform charge density of σ, is given by the following expression, where x is the distance of the point from the disk. (R2 + x2)1/2 Consider a disk of radius R-3.27 cm having a uniformly distributed charge of +5.18 C. (a) Using the expression above, compute the electric field at a point on the axis and 3.30 mm...
