Often within clearing zones on the spot test, you may observe tiny colonies of bacteria that have somehow not been lysed by the phage. Give one explanation of what these colonies might be (besides contamination)
Homework Answers
These colonies might be those colonies that have not yet undergone complete lysis or it might be that those colonies are partially resistant to the phage.

Practice Questions 1. You were given a bacteria for unknown investigation. To begin with, you performed a Methyl Red test after inoculating and incubating them for 48 hours. You obtained no color change after addition of Methyl Red. You proceed forward and performed Voges Proskauer test. For this particular test, you obtained a red color change after addition of Barritt solution A and B. From the result, what kind of inference can you draw from the 2 results obtained about...

1. The 1952 experiment performed by the Lederbergs in which they replica-plated ten million colonies of TI-phage sensitive E. coli to plates containing high concentrations of TI phase and found a small number of phage-resistant colonies showed that: A) a selecting agent can affect mutation rate in E. coli. B) mutations can arise spontaneously before exposure to the selecting agent. C) mutations in E. coli occur at a relatively high frequency, D) the mutation rate in E. coli fluctuates greatly...

Your assignment is to create and test a class for a queue of objects. You may use any object class of your choice as the data for the queue. The instances of the class should have at least one field that distinguishes each instance from other instances of the class (key property, also called a key field). You should complete the software to implement and test your queue and submit the software along with a project report. Your queue class...

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...

You have been admitted to your local hospital for chest pain. An EKG was performed on you and now you are waiting for a lab technician to draw blood to test your cardiac enzyme levels. Moments before the technician arrives your nurse comes in with a puzzled look. You ask what's wrong and they mention that another EKG order has appeared for you. The nurse verifies that you have in fact just had one and steps out to contact the...
