T0 ( time zero) shows assay performed in order to obtain an absorbance at the time of test agent added in order to determine 1. how much cells have grown over the incubation period 2. Growth inhibition by test agent 3. If test agent caused cytotoxicityYou perform a Kirby-Bauer assay with two antibiotics. Antibiotic X has a zone of inhibition of 9 mm. Antibiotic Y has a zone of inhibition of 11 mm. Which antibiotic is better at killing this particular microorganism? Group of answer choices 1Antibiotic Y 2Antibiotic X and Y, which have identical antimicrobial activities 3Antibiotic X4 4It is impossible to tell from the information givenPlease answer fast Dilution Problem. A culture of Staphylococcus is diluted as follows: (1) 20mL are added to 80mL of water. (2) 10uL from (1) are then added to 9.99mL of water. (3) A 10-2 dilution is made from tube # (2).

- If you have 4 compounds and you test them for antimicrobial activity using a disk diffusion assay and one is very active, one is moderately active, one is slightly active and one is not active at all, draw the disk, the zone of inhibition that you would see and a pretend numerical value to indicate the size of the zone in mm, give each one a number 1 – 4 and rank them from most effective to least effective as an antimicrobial.The table below shows the response of our ESKAPE safe relatives to 4 bacteria isolated from a master grid. We do not know the identity or any characteristics of the unknown bacteria. Each safe relative was spread onto a petri dish using aseptic technique. A grid pattern was taped to each plate and the unknown bacteria were patched into one of the squares. If there was no inhibition visible, including with a magnifying lens, the result was listed as -. If there was an inhibition zone between 1 and 10mm in diameter, the result is listed as +. If the inhibition zone was greater than 10mm, the result is listed as ++. Page 50 in your research guide states: "Some antibiotics are broad spectrum, meaning that they affect a wide range of bacteria. Other antibiotics have a narrow spectrum of activity. One anatomical feature that plays a significant role in the susceptibility of a microbe to a particular antibiotic is its cell wall composition (discussed in Section 8)".

MRSA 2) How does the MIC test differ from the Kirby-Bauer test? 3) Were all of the conditions of a standardized Kirby-Bauer test met as you performed this assay? If not, which were not? 4) What is the significance of colonies that develop within otherwise clear zones of inhibition?

Control. 500 ml of cottage cheese was inoculated with 2 ml of a 24-hr culture of Pseudomonas aeruginosa and incubated at 25°C. Five hours after inoculation, a standard plate count showed there were 200 bacterial cells/ml in the cottage cheese. After 11 hours, 1600 cells/ml. After 21 hours, 50,000 cells/ml. After 27 hours, 400,000 cells/ml. Experiment. 500 ml of cottage cheese containing the preservative was inoculated with 2 ml of a 24-hr culture of P. aeruginosa. After 6 hours of incubation at 25°C, a standard plate count was performed. There were 700 bacterial cells/ml in the cottage cheese. After 14 hours, 11,000 cells/ml. After 20 hours, 90,000 cells/ml. After 28 hours, 1, 400, 000 cells/ml. Use the data and the semi-log graph paper to plot growth curves for the control and the experiment. Remember to label…
