Summary Introduction
To review:
The observation of microbes by light and electron microscopy.
Introduction:
The perception of microorganisms started nearly 300 years ago with the development of microscopes. The initial microscopes were made up of a simple ground glass lens by Leeuwenhoek that could detect the presence of microbes. The development of microscopes from simple to compound with further technical advances helped improve our detailed understanding of the microbial world. Microscopes help in better understanding the key details of the microbes.

Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope.
c) After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry. Explain, based on microscopy principles, why this has occurred
Provide a description of the procedure to prepare an acidic stain of bacteria using Nigrosin as it would appear in the Methods section.
Both stained and live organisms are viewed using a microscope, but what is the purpose/benefit of staining a microorganism versus not staining it?
Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope.
At 100X you are unable to see the diatom. Explain why.
Explain what correction (s) should be made to allow you to see the diatom using the 100X lens.
After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry. Explain, based on microscopy principles, why this has occurred.

- Which Two types of electron microscopy are in routine use in microbiology? Explainarrow_forwardPlease discuss why staining is important in visualizing microbes under the microscope. What different types of staining methods can be used?arrow_forwardA student missed the laboratory period where the use of the microscope was demonstrated. The instructor asked the student to read the description in the laboratory manual and then proceed to examine bacterial cells with the oil immersion lens. The student skimmed the directions and began. After about 15 minutes of struggling, the student gave up in despair without seeing anything. Below is a detailed description of what the student did. How many mistakes did the student make and why didn’t the student see anything? a. Plugged in the microscope and turned the light source to maximum intensity. Made a wet mount and placed it on the stage with the low-power objective lens in position. Tried to focus with the coarse adjustment, but decided the bacteria were too small and needed to be seen with the high-power objective lens. Rotated the high-power objective lens into position, but saw the lens would likely touch the slide, so lowered the stage so that the objective lens rotated freely.…arrow_forward

- Describe in detail all the steps needed to determine whether an Unknown bacteria has a Gram-positive or Gram-negative cell wall using the Gram stain. (You can describe the method presented in the Exercise 3-6 Gram stain videos or in the Lab Manual.) 1. Start by describing the method of transferring the bacteria onto the microscope slide, then describe heat-fixing the emulsion of the Unknown bacteria. (Do not describe all the steps needed to perform aseptic technique. Just say “Bacteria was added aseptically.”) 2. Describe the Gram stain in detail.
