When testing the efficacy of an antibiotic against bacteria on an agar plate, it is important to spread the bacteria evenly across the plate before you add the antibiotic. Why do the bacteria need to be applied evenly? None of the following are true All of the following are true If you add more bacteria in some areas compared to others, it might obscure the effect of the antibiotic If the area right next to the antibiotic initially received relatively few bacterial cells, that might lead you to overestimate the effectiveness of the antibiotic If the area right next to the antibiotic initially received a relatively large number of bacterial cells, that might lead you to underestimate the effectiveness of the antibiotic
EXPERIMENT 2 Title: Aseptic technique Objectives: To apply the aseptic technique To observe the growth found on the petri dish. Material/apparatus: Gloves, incubator, soap for handwashing, tissues, nutrient agar, 70% alcohol Procedure: Wipe off the bench with 70% alcohol. Draw a line down the middle of the petri dish to divide the plate in half. Label each halves with A and B. Press your unwashed thumb onto the agar at column A. Apply proper handwashing technique. Put the same thumb after washing onto agar at the column B. Incubate the petri dish at 37°C for 24 hours or overnight. Observe and note down the colonies. Results:
What is an E-test strip, and what is it used for in the microbiology laboratory? Draw a diagram of an E-test strip.
Discuss fresh, living preparations vs fixed preparations. What are the advantages and disadvantages of each technique in a microbiology laboratory?
during inoculation, the bacterial culture tube is always held at an angle and the lid of the Petri dish is slightly open. Explain the purpose of these steps briefly.
In the conduct of serial dilution, which of the following tools is NOT necessary? a. Agar plates b. Micropipettor c. Inoculating needle d. Alcohol lamp or Bunsen burner e. Test tubes or microcentrifuge tubes
Using saline tubes containing 9 ml of saline (for dilutions), draw a diagram that would yield between 30 and 300 colonies from an original broth culture that contains 5 * 10^8 cells/ml. Indicate volumes used and dilutions made for each tube and plate.
