35) Refer to the treatments listed to answer the question. You isolate an infectious substance capable of causing discase in plants, but you do not know whether the infectious agent is a bacterium, virus, or prion. You have four methods at your disposa to analyze the substance and determine the nature of the infectious agent. I. Treat the substance with enzymes that destroy all nucleic acids, and then determine whether the substance is still infectious. II. Filter the substance to...

Suppose you would like to determine the number of bacteria in a culture via an aerobic plate count. Explain (with pictures) how you would set up a dilution series (104, 106, 10) using the fewest number of dilution blanks. Draw and label your tubes and plates with each dilution. Show all volumes including transfers, amounts in tubes, and amounts plated 1. You want to set up a 1:10 dilution series, so that you can plate a 10-1, 102, and a...

You are given a mixed culture of two organisms in a small tube of TSB.
You are given a mixed culture of two organisms in a small tube of TSB. These two organisms include a Gram-negative strain (your bacterial strain to identify) and a Gram-positive strain (a contaminant). Your first task is to isolate these organisms which will help you identify which Gram-negative strain you are working with. 1) You inoculate two streak plates on TSA media and MacConkey Agar using aseptic technique. For each medium, state whether the medium is selective, differential, or neither and...

1. You are studying phage transduction and trying to deliver a kanamycin resistance gene from one strain of bacteria to another using phage. The kanR gene is FAR away from the lambda prophage in your bacterium. Choose which type of transduction should you use for your experiment and explain why. a. lambda phage, specialized transduction b. lambda phage, conjugation C. T4 phage, generalized transduction d. A different phage with mitomycin C induction 2. A pig is infected with two subtypes...

You notice that there is an increasing prevalence of a bacterial infection at your hospital that appears to be affecting people. The bacterium has been named T. routmania, and microbiologists have found that it is a gram negative organism that is highly resistant to typical antibiotics. Immunologists have found that the organism appears to target T-cells in the host. Analysis of lymphatic fluid from infected patients has found an unusually low level of IL-2, yet tissue samples appear to have...
