Part II: Bacterial Anatomy The purpose of this experiment is to become familiar and gain an understanding of how morphology and the arrangement of bacteria relate to staining techniques. Sample 1 In this study a female patient who had a problem that had arisen suddenly after lunch‚ had allergic reaction to something that she ate or drank had sent her to the bathroom with cramps and copious diarrhea. She knew she

incubated at 37C for 24- 48 hours‚ and two separate morphologies were then observed and recorded‚ unknown A and unknown B‚ a Gram stain was then performed for each unknown. After determining the Gram reaction‚ alternate staining procedures were performed as needed. Unknown A required further endospore staining‚ whereas unknown B required no further staining procedures. Once all staining methods were complete‚ specific biochemical tests were performed. The biochemical tests were chosen from the unknown

1 1. Explain the principle of positive staining. (3 marks) Positive staining is done by staining the cell walls of Gram-positive bacteria with crystal violet. The cell wall of Gram-positive bacteria is made up of a thick layer of peptidoglycan which undergoes dehydration during decolourisation causing the pores to shrink. This shrinkage of pores traps CV-I complex and stain the cell purple. 2. Using a flow chart‚ outline the process of gram staining. (5 marks) Flood the slide with crystal

Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of staining is the Gram Staining‚ as it is highly dependent
